+# Contribute to freqtrade
+
+Feel like our bot is missing a feature? We welcome your pull requests! Few pointers for contributions:
+
+- Create your PR against the `develop` branch, not `master`.
+- New features need to contain unit tests and must be PEP8 
+conformant (max-line-length = 100).
+
+If you are unsure, discuss the feature on our [Slack](https://join.slack.com/t/highfrequencybot/shared_invite/enQtMjQ5NTM0OTYzMzY3LWMxYzE3M2MxNDdjMGM3ZTYwNzFjMGIwZGRjNTc3ZGU3MGE3NzdmZGMwNmU3NDM5ZTNmM2Y3NjRiNzk4NmM4OGE)
+or in a [issue](https://github.com/gcarq/freqtrade/issues) before a PR.
+
+
+**Before sending the PR:**
+
+## 1. Run unit tests
+
+All unit tests must pass. If a unit test is broken, change your code to 
+make it pass. It means you have introduced a regression.
+
+**Test the whole project**
+```bash
+pytest freqtrade
+```
+
+**Test only one file**
+```bash
+pytest freqtrade/tests/test_<file_name>.py
+```
+
+**Test only one method from one file**
+```bash
+pytest freqtrade/tests/test_<file_name>.py::test_<method_name>
+```
+
+## 2. Test if your code is PEP8 compliant
+**Install packages** (If not already installed)
+```bash
+pip3.6 install flake8 coveralls
+``` 
+**Run Flake8**
+```bash
+flake8 freqtrade
+```

+Simple High frequency trading bot for crypto currencies designed to 
+support multi exchanges and be controlled via Telegram.
 
-The command interface is accessible via Telegram (not required).
-Just register a new bot on https://telegram.me/BotFather
-and enter the telegram `token` and your `chat_id` in `config.json`
+![freqtrade](https://raw.githubusercontent.com/gcarq/freqtrade/develop/docs/assets/freqtrade-screenshot.png)

+## Disclaimer
+This software is for educational purposes only. Do not risk money which 
+you are afraid to lose. USE THE SOFTWARE AT YOUR OWN RISK. THE AUTHORS 
+AND ALL AFFILIATES ASSUME NO RESPONSIBILITY FOR YOUR TRADING RESULTS. 
 
-#### Telegram RPC commands:
-* /start: Starts the trader
-* /stop: Stops the trader
-* /status: Lists all open trades
-* /profit: Lists cumulative profit from all finished trades
-* /forcesell <trade_id>: Instantly sells the given trade (Ignoring `minimum_roi`).
-* /performance: Show performance of each finished trade grouped by pair
+Always start by running a trading bot in Dry-run and do not engage money
+before you understand how it works and what profit/loss you should
+expect.
 
-#### Config
-`minimal_roi` is a JSON object where the key is a duration
-in minutes and the value is the minimum ROI in percent.
-See the example below:
+We strongly recommend you to have coding and Python knowledge. Do not 
+hesitate to read the source code and understand the mechanism of this bot.

+
+## Quick start
+This quick start section is a very short explanation on how to test the 
+bot in dry-run. We invite you to read the 
+[bot documentation](https://github.com/gcarq/freqtrade/blob/develop/docs/index.md) 
+to ensure you understand how the bot is working.
+
+The following steps are made for Linux/MacOS environment
+
+**1. Clone the repo**
+```bash
+git clone git@github.com:gcarq/freqtrade.git
+git checkout develop
+cd freqtrade
 ```
-"minimal_roi": {
-    "2880": 0.005, # Sell after 48 hours if there is at least 0.5% profit
-    "1440": 0.01,  # Sell after 24 hours if there is at least 1% profit
-    "720":  0.02,  # Sell after 12 hours if there is at least 2% profit
-    "360":  0.02,  # Sell after 6 hours if there is at least 2% profit
-    "0":    0.025  # Sell immediately if there is at least 2.5% profit
-},
+**2. Create the config file**  
+Switch `"dry_run": true,`
+```bash
+cp config.json.example config.json
+vi config.json
+```
+**3. Build your docker image and run it**
+```bash
+docker build -t freqtrade .
+docker run --rm -v `pwd`/config.json:/freqtrade/config.json -it freqtrade
 ```
 
-`stoploss` is loss in percentage that should trigger a sale. 
-For example value `-0.10` will cause immediate sell if the
-profit dips below -10% for a given trade. This parameter is optional.
 
-`initial_state` is an optional field that defines the initial application state.
-Possible values are `running` or `stopped`. (default=`running`)
-If the value is `stopped` the bot has to be started with `/start` first.
+### Help / Slack
+For any questions not covered by the documentation or for further
+information about the bot, we encourage you to join our slack channel.

+# Backtesting
+This page explains how to validate your strategy performance by using 
+Backtesting.
+
+## Table of Contents
+- [Test your strategy with Backtesting](#test-your-strategy-with-backtesting)
+- [Understand the backtesting result](#understand-the-backtesting-result)
+
+## Test your strategy with Backtesting
+Now you have good Buy and Sell strategies, you want to test it against
+real data. This is what we call 
+[backtesting](https://en.wikipedia.org/wiki/Backtesting).
+
+
+Backtesting will use the crypto-currencies (pair) from your config file
+and load static tickers located in 
+[/freqtrade/tests/testdata](https://github.com/gcarq/freqtrade/tree/develop/freqtrade/tests/testdata).
+If the 5 min and 1 min ticker for the crypto-currencies to test is not 
+already in the `testdata` folder, backtesting will download them 
+automatically. Testdata files will not be updated until you specify it.
+
+The result of backtesting will confirm you if your bot as more chance to
+make a profit than a loss.
+
+
+The backtesting is very easy with freqtrade.
+
+### Run a backtesting against the currencies listed in your config file
+**With 5 min tickers (Per default)**
+```bash
+python3 ./freqtrade/main.py backtesting --realistic-simulation
+```
+
+**With 1 min tickers**
+```bash
+python3 ./freqtrade/main.py backtesting --realistic-simulation --ticker-interval 1
+```
+
+**Reload your testdata files**
+```bash
+python3 ./freqtrade/main.py backtesting --realistic-simulation --refresh-pairs-cached
+```
+
+**With live data (do not alter your testdata files)**
+```bash
+python3 ./freqtrade/main.py backtesting --realistic-simulation --live
+```
+
+**Using a different on-disk ticker-data source**
+```bash
+python3 ./freqtrade/main.py backtesting --datadir freqtrade/tests/testdata-20180101
+```
+
+For help about backtesting usage, please refer to 
+[Backtesting commands](#backtesting-commands).
+
+## Understand the backtesting result
+The most important in the backtesting is to understand the result.
+
+A backtesting result will look like that:
+```

+BTC_NXT            24            0.68          0.00031833            40.2
+BTC_POWR           35            0.98          0.00064887            45.3
+BTC_ADA            43           -0.39         -0.00032292            55.0
+BTC_XMR            40           -0.40         -0.00032181            47.4
+TOTAL             419           -0.41         -0.00348593            52.9
+```
+
+The last line will give you the overall performance of your strategy,
+here:
+```
+TOTAL             419           -0.41         -0.00348593            52.9
+```
+
+We understand the bot has made `419` trades for an average duration of
+`52.9` min, with a performance of `-0.41%` (loss), that means it has 
+lost a total of `-0.00348593 BTC`.
+ 
+As you will see your strategy performance will be influenced by your buy 
+strategy, your sell strategy, and also by the `minimal_roi` and 
+`stop_loss` you have set. 
+
+As for an example if your minimal_roi is only `"0":  0.01`. You cannot
+expect the bot to make more profit than 1% (because it will sell every 
+time a trade will reach 1%).
+```json
+"minimal_roi": {
+    "0":  0.01
+},
+```
+
+On the other hand, if you set a too high `minimal_roi` like `"0":  0.55`
+(55%), there is a lot of chance that the bot will never reach this 
+profit. Hence, keep in mind that your performance is a mix of your 
+strategies, your configuration, and the crypto-currency you have set up.
+
+## Next step
+Great, your strategy is profitable. What if the bot can give your the
+optimal parameters to use for your strategy?  
+Your next step is to learn [how to find optimal parameters with Hyperopt](https://github.com/gcarq/freqtrade/blob/develop/docs/hyperopt.md)

+# Bot Optimization
+This page explains where to customize your strategies, and add new 
+indicators. 
+
+## Table of Contents
+- [Change your strategy](#change-your-strategy)
+- [Add more Indicator](#add-more-indicator)
+
+## Change your strategy
+The bot is using buy and sell strategies to buy and sell your trades. 
+Both are customizable.
+
+### Buy strategy
+The default buy strategy is located in the file 
+[freqtrade/analyze.py](https://github.com/gcarq/freqtrade/blob/develop/freqtrade/analyze.py#L73-L92). 
+Edit the function `populate_buy_trend()` to update your buy strategy.
+
+Sample:
+```python
+def populate_buy_trend(dataframe: DataFrame) -> DataFrame:
+    """
+    Based on TA indicators, populates the buy signal for the given dataframe
+    :param dataframe: DataFrame
+    :return: DataFrame with buy column
+    """
+    dataframe.loc[
+        (
+            (dataframe['rsi'] < 35) &
+            (dataframe['fastd'] < 35) &
+            (dataframe['adx'] > 30) &
+            (dataframe['plus_di'] > 0.5)
+        ) |
+        (
+            (dataframe['adx'] > 65) &
+            (dataframe['plus_di'] > 0.5)
+        ),
+        'buy'] = 1
+
+    return dataframe
+```
+
+### Sell strategy
+The default buy strategy is located in the file 
+[freqtrade/analyze.py](https://github.com/gcarq/freqtrade/blob/develop/freqtrade/analyze.py#L95-L115)
+Edit the function `populate_sell_trend()` to update your buy strategy.
+
+Sample:
+```python
+def populate_sell_trend(dataframe: DataFrame) -> DataFrame:
+    """
+    Based on TA indicators, populates the sell signal for the given dataframe
+    :param dataframe: DataFrame
+    :return: DataFrame with buy column
+    """
+    dataframe.loc[
+        (
+            (
+                (crossed_above(dataframe['rsi'], 70)) |
+                (crossed_above(dataframe['fastd'], 70))
+            ) &
+            (dataframe['adx'] > 10) &
+            (dataframe['minus_di'] > 0)
+        ) |
+        (
+            (dataframe['adx'] > 70) &
+            (dataframe['minus_di'] > 0.5)
+        ),
+        'sell'] = 1
+    return dataframe
+```
+
+## Add more Indicator
+As you have seen, buy and sell strategies need indicators. You can see 
+the indicators in the file 
+[freqtrade/analyze.py](https://github.com/gcarq/freqtrade/blob/develop/freqtrade/analyze.py#L95-L115).
+Of course you can add more indicators by extending the list contained in
+the function `populate_indicators()`.
+
+Sample:
+```python
+def populate_indicators(dataframe: DataFrame) -> DataFrame:
+    """
+    Adds several different TA indicators to the given DataFrame
+    """
+    dataframe['sar'] = ta.SAR(dataframe)
+    dataframe['adx'] = ta.ADX(dataframe)
+    stoch = ta.STOCHF(dataframe)
+    dataframe['fastd'] = stoch['fastd']
+    dataframe['fastk'] = stoch['fastk']
+    dataframe['blower'] = ta.BBANDS(dataframe, nbdevup=2, nbdevdn=2)['lowerband']
+    dataframe['sma'] = ta.SMA(dataframe, timeperiod=40)
+    dataframe['tema'] = ta.TEMA(dataframe, timeperiod=9)
+    dataframe['mfi'] = ta.MFI(dataframe)
+    dataframe['rsi'] = ta.RSI(dataframe)
+    dataframe['ema5'] = ta.EMA(dataframe, timeperiod=5)
+    dataframe['ema10'] = ta.EMA(dataframe, timeperiod=10)
+    dataframe['ema50'] = ta.EMA(dataframe, timeperiod=50)
+    dataframe['ema100'] = ta.EMA(dataframe, timeperiod=100)
+    dataframe['ao'] = awesome_oscillator(dataframe)
+    macd = ta.MACD(dataframe)
+    dataframe['macd'] = macd['macd']
+    dataframe['macdsignal'] = macd['macdsignal']
+    dataframe['macdhist'] = macd['macdhist']
+    hilbert = ta.HT_SINE(dataframe)
+    dataframe['htsine'] = hilbert['sine']
+    dataframe['htleadsine'] = hilbert['leadsine']
+    dataframe['plus_dm'] = ta.PLUS_DM(dataframe)
+    dataframe['plus_di'] = ta.PLUS_DI(dataframe)
+    dataframe['minus_dm'] = ta.MINUS_DM(dataframe)
+    dataframe['minus_di'] = ta.MINUS_DI(dataframe)
+    return dataframe
+```
+

+## Bot commands
+```
+usage: main.py [-h] [-c PATH] [-v] [--version] [--dynamic-whitelist [INT]]
+               [--dry-run-db]
+               {backtesting,hyperopt} ...
+
+Simple High Frequency Trading Bot for crypto currencies
+
+positional arguments:
+  {backtesting,hyperopt}
+    backtesting         backtesting module
+    hyperopt            hyperopt module
+
+optional arguments:
+  -h, --help            show this help message and exit
+  -c PATH, --config PATH
+                        specify configuration file (default: config.json)
+  -v, --verbose         be verbose
+  --version             show program's version number and exit
+  -dd PATH, --datadir PATH
+                        Path is from where backtesting and hyperopt will load the
+                        ticker data files (default freqdata/tests/testdata).
+  --dynamic-whitelist [INT]
+                        dynamically generate and update whitelist based on 24h
+                        BaseVolume (Default 20 currencies)
+  --dry-run-db          Force dry run to use a local DB
+                        "tradesv3.dry_run.sqlite" instead of memory DB. Work
+                        only if dry_run is enabled.
+```
+
+### How to use a different config file?
+The bot allows you to select which config file you want to use. Per 
+default, the bot will load the file `./config.json`
+
+```bash
+python3 ./freqtrade/main.py -c path/far/far/away/config.json 
+```
+
+### How to use --dynamic-whitelist?
+Per default `--dynamic-whitelist` will retrieve the 20 currencies based 
+on BaseVolume. This value can be changed when you run the script.
+
+**By Default**  
+Get the 20 currencies based on BaseVolume.  
+```bash
+python3 ./freqtrade/main.py --dynamic-whitelist
+```
+
+**Customize the number of currencies to retrieve**  
+Get the 30 currencies based on BaseVolume.  
+```bash
+python3 ./freqtrade/main.py --dynamic-whitelist 30
+```
+
+**Exception**  
+`--dynamic-whitelist` must be greater than 0. If you enter 0 or a
+negative value (e.g -2), `--dynamic-whitelist` will use the default
+value (20).
+
+### How to use --dry-run-db?
+When you run the bot in Dry-run mode, per default no transactions are 
+stored in a database. If you want to store your bot actions in a DB 
+using `--dry-run-db`. This command will use a separate database file 
+`tradesv3.dry_run.sqlite`
+
+```bash
+python3 ./freqtrade/main.py -c config.json --dry-run-db
+```
+
+
+## Backtesting commands
+
+Backtesting also uses the config specified via `-c/--config`.
+
+```
+usage: freqtrade backtesting [-h] [-l] [-i INT] [--realistic-simulation]
+                             [-r]
+
+optional arguments:
+  -h, --help            show this help message and exit
+  -l, --live            using live data
+  -i INT, --ticker-interval INT
+                        specify ticker interval in minutes (default: 5)
+  --realistic-simulation
+                        uses max_open_trades from config to simulate real
+                        world limitations
+  -r, --refresh-pairs-cached
+                        refresh the pairs files in tests/testdata with 
+                        the latest data from Bittrex. Use it if you want
+                        to run your backtesting with up-to-date data.
+```
+
+### How to use --refresh-pairs-cached parameter?
+The first time your run Backtesting, it will take the pairs you have 
+set in your config file and download data from Bittrex. 
+
+If for any reason you want to update your data set, you use 
+`--refresh-pairs-cached` to force Backtesting to update the data it has. 
+**Use it only if you want to update your data set. You will not be able
+to come back to the previous version.**
+
+To test your strategy with latest data, we recommend continuing using 
+the parameter `-l` or `--live`.
+
+
+## Hyperopt commands
+
+It is possible to use hyperopt for trading strategy optimization.
+Hyperopt uses an internal json config return by `hyperopt_optimize_conf()` 
+located in `freqtrade/optimize/hyperopt_conf.py`.
+
+```
+usage: freqtrade hyperopt [-h] [-e INT] [--use-mongodb]
+
+optional arguments:
+  -h, --help            show this help message and exit
+  -e INT, --epochs INT  specify number of epochs (default: 100)
+  --use-mongodb         parallelize evaluations with mongodb (requires mongod
+                        in PATH)
+
+```
+
+## A parameter missing in the configuration?
+All parameters for `main.py`, `backtesting`, `hyperopt` are referenced
+in [misc.py](https://github.com/gcarq/freqtrade/blob/develop/freqtrade/misc.py#L84)
+
+## Next step
+The optimal strategy of the bot will change with time depending of the
+market trends. The next step is to 
+[optimize your bot](https://github.com/gcarq/freqtrade/blob/develop/docs/bot-optimization.md).

+## Setup config.json
+We recommend to copy and use the `config.json.example` as a template
+for your bot configuration.
+
+The table below will list all configuration parameters. 
+
+|  Command | Default | Mandatory | Description |
+|----------|---------|----------|-------------|
+| `max_open_trades` | 3 | Yes | Number of trades open your bot will have.
+| `stake_currency` | BTC | Yes | Crypto-currency used for trading.
+| `stake_amount` | 0.05 | Yes | Amount of crypto-currency your bot will use for each trade. Per default, the bot will use (0.05 BTC x 3) = 0.15 BTC in total will be always engaged.
+| `fiat_display_currency` | USD | Yes | Fiat currency used to show your profits. More information below. 
+| `dry_run` | true | Yes | Define if the bot must be in Dry-run or production mode. 
+| `minimal_roi` | See below | Yes | Set the threshold in percent the bot will use to sell a trade. More information below. 
+| `stoploss` | -0.10 | No | Value of the stoploss in percent used by the bot. More information below. 
+| `unfilledtimeout` | 0 | No | How long (in minutes) the bot will wait for an unfilled order to complete, after which the order will be cancelled.
+| `bid_strategy.ask_last_balance` | 0.0 | Yes | Set the bidding price. More information below.
+| `exchange.name` | bittrex | Yes | Name of the exchange class to use.
+| `exchange.key` | key | No | API key to use for the exchange. Only required when you are in production mode.
+| `exchange.secret` | secret | No | API secret to use for the exchange. Only required when you are in production mode.
+| `exchange.pair_whitelist` | [] | No | List of currency to use by the bot. Can be overrided with `--dynamic-whitelist` param.
+| `exchange.pair_blacklist` | [] | No | List of currency the bot must avoid. Useful when using `--dynamic-whitelist` param.
+| `experimental.use_sell_signal` | false | No | Use your sell strategy in addition of the `minimal_roi`.
+| `telegram.enabled` | true | Yes | Enable or not the usage of Telegram.
+| `telegram.token` | token | No | Your Telegram bot token. Only required is `enable` is `true`.
+| `telegram.chat_id` | chat_id | No | Your personal Telegram account id. Only required is `enable` is `true`.
+| `initial_state` | running | No | Defines the initial application state. More information below.
+| `internals.process_throttle_secs` | 5 | Yes | Set the process throttle. Value in second.
+
+The definition of each config parameters is in 
+[misc.py](https://github.com/gcarq/freqtrade/blob/develop/freqtrade/misc.py#L205).
+
+### Understand minimal_roi
+`minimal_roi` is a JSON object where the key is a duration
+in minutes and the value is the minimum ROI in percent.
+See the example below:
+```
+"minimal_roi": {
+    "40": 0.0,    # Sell after 40 minutes if the profit is not negative
+    "30": 0.01,   # Sell after 30 minutes if there is at least 1% profit
+    "20": 0.02,   # Sell after 20 minutes if there is at least 2% profit
+    "0":  0.04    # Sell immediately if there is at least 4% profit
+},
+```
+
+### Understand stoploss
+`stoploss` is loss in percentage that should trigger a sale.
+For example value `-0.10` will cause immediate sell if the
+profit dips below -10% for a given trade. This parameter is optional.
+
+### Understand initial_state
+`initial_state` is an optional field that defines the initial application state.
+Possible values are `running` or `stopped`. (default=`running`)
+If the value is `stopped` the bot has to be started with `/start` first.
+
+### Understand ask_last_balance
+`ask_last_balance` sets the bidding price. Value `0.0` will use `ask` price, `1.0` will
+use the `last` price and values between those interpolate between ask and last
+price. Using `ask` price will guarantee quick success in bid, but bot will also
+end up paying more then would probably have been necessary.
+
+### What values for fiat_display_currency?
+`fiat_display_currency` set the fiat to use for the conversion form coin to fiat in Telegram. 
+The valid value are: "AUD", "BRL", "CAD", "CHF", "CLP", "CNY", "CZK", "DKK", "EUR", "GBP", "HKD", "HUF", "IDR", "ILS", "INR", "JPY", "KRW", "MXN", "MYR", "NOK", "NZD", "PHP", "PKR", "PLN", "RUB", "SEK", "SGD", "THB", "TRY", "TWD", "ZAR", "USD".
+
+## Switch to dry-run mode
+We recommend starting the bot in dry-run mode to see how your bot will
+behave and how is the performance of your strategy. In Dry-run mode the
+bot does not engage your money. It only runs a live simulation without
+creating trades.
+
+### To switch your bot in Dry-run mode:
+1. Edit your `config.json`  file
+2. Switch dry-run to true
+```json
+"dry_run": true,
+```
+
+3. Remove your Bittrex API key (change them by fake api credentials)
+```json
+"exchange": {
+        "name": "bittrex",
+        "key": "key",
+        "secret": "secret",
+        ...
+}   
+```
+
+Once you will be happy with your bot performance, you can switch it to 
+production mode.
+
+## Switch to production mode
+In production mode, the bot will engage your money. Be careful a wrong 
+strategy can lose all your money. Be aware of what you are doing when 
+you run it in production mode.
+
+### To switch your bot in production mode:
+1. Edit your `config.json`  file
+
+2. Switch dry-run to false
+```json
+"dry_run": false,
+```
+
+3. Insert your Bittrex API key (change them by fake api keys)
+```json
+"exchange": {
+        "name": "bittrex",
+        "key": "af8ddd35195e9dc500b9a6f799f6f5c93d89193b",
+        "secret": "08a9dc6db3d7b53e1acebd9275677f4b0a04f1a5",
+        ...
+}       
+```
+If you have not your Bittrex API key yet, 
+[see our tutorial](https://github.com/gcarq/freqtrade/blob/develop/docs/pre-requisite.md).
+
+
+## Next step
+Now you have configured your config.json, the next step is to 
+[start your bot](https://github.com/gcarq/freqtrade/blob/develop/docs/bot-usage.md).

+# freqtrade FAQ
+
+#### I have waited 5 minutes, why hasn't the bot made any trades yet?!
+
+Depending on the buy strategy, the amount of whitelisted coins, the situation of the market etc, it can take up to hours to find good entry position for a trade. Be patient!
+
+#### I have made 12 trades already, why is my total profit negative?!
+
+I understand your disappointment but unfortunately 12 trades is just not enough to say anything. If you run backtesting, you can see that our current algorithm does leave you on the plus side, but that is after thousands of trades and even there, you will be left with losses on specific coins that you have traded tens if not hundreds of times. We of course constantly aim to improve the bot but it will _always_ be a gamble, which should leave you with modest wins on monthly basis but you can't say much from few trades.
+
+#### I’d like to change the stake amount. Can I just stop the bot with /stop and then change the config.json and run it again?
+
+Not quite. Trades are persisted to a database but the configuration is currently only read when the bot is killed and restarted. `/stop` more like pauses. You can stop your bot, adjust settings and start it again.
+
+#### I want to improve the bot with a new strategy
+
+That's great. We have a nice backtesting and hyperoptimizing setup. See the tutorial [[here|Testing-new-strategies-with-Hyperopt]].
+
+#### Is there a setting to only SELL the coins being held and not perform anymore BUYS?
+
+You can use the `/forcesell all` command from Telegram.

+parameters with Hyperopt.

+
+## Prepare Hyperopt
+Before we start digging in Hyperopt, we recommend you to take a look at 
+out Hyperopt file 
+[freqtrade/optimize/hyperopt.py](https://github.com/gcarq/freqtrade/blob/develop/freqtrade/optimize/hyperopt.py)
+ 
+### 1. Configure your Guards and Triggers
+There are two places you need to change to add a new buy strategy for 
+testing:
+- Inside the [populate_buy_trend()](https://github.com/gcarq/freqtrade/blob/develop/freqtrade/optimize/hyperopt.py#L167-L207).
+- Inside the [SPACE dict](https://github.com/gcarq/freqtrade/blob/develop/freqtrade/optimize/hyperopt.py#L47-L94).
+
+There you have two different type of indicators: 1. `guards` and 2. 
+`triggers`.
+1. Guards are conditions like "never buy if ADX < 10", or never buy if 
+current price is over EMA10.
+2. Triggers are ones that actually trigger buy in specific moment, like 
+"buy when EMA5 crosses over EMA10" or buy when close price touches lower 
+bollinger band.
+
+HyperOpt will, for each eval round, pick just ONE trigger, and possibly 
+multiple guards. So that the constructed strategy will be something like 
+"*buy exactly when close price touches lower bollinger band, BUT only if 
+ADX > 10*".
+
+
+If you have updated the buy strategy, means change the content of
+`populate_buy_trend()` function you have to update the `guards` and 
+`triggers` hyperopts must used.
+
+As for an example if your `populate_buy_trend()` function is:
+```python
+def populate_buy_trend(dataframe: DataFrame) -> DataFrame:
+    dataframe.loc[
+        (dataframe['rsi'] < 35) &
+        (dataframe['adx'] > 65),
+        'buy'] = 1
+
+    return dataframe
+```
+
+Your hyperopt file must contains `guards` to find the right value for 
+`(dataframe['adx'] > 65)` & and `(dataframe['plus_di'] > 0.5)`. That 
+means you will need to enable/disable triggers.
+ 
+In our case the `SPACE` and `populate_buy_trend` in hyperopt.py file 
+will be look like:
+```python
+SPACE = {
+    'rsi': hp.choice('rsi', [
+        {'enabled': False},
+        {'enabled': True, 'value': hp.quniform('rsi-value', 20, 40, 1)}
+    ]),
+    'adx': hp.choice('adx', [
+        {'enabled': False},
+        {'enabled': True, 'value': hp.quniform('adx-value', 15, 50, 1)}
+    ]),
+    'trigger': hp.choice('trigger', [
+        {'type': 'lower_bb'},
+        {'type': 'faststoch10'},
+        {'type': 'ao_cross_zero'},
+        {'type': 'ema5_cross_ema10'},
+        {'type': 'macd_cross_signal'},
+        {'type': 'sar_reversal'},
+        {'type': 'stochf_cross'},
+        {'type': 'ht_sine'},
+    ]),
+}
+
+... 
+
+def populate_buy_trend(dataframe: DataFrame) -> DataFrame:
+        conditions = []
+        # GUARDS AND TRENDS
+        if params['adx']['enabled']:
+            conditions.append(dataframe['adx'] > params['adx']['value'])
+        if params['rsi']['enabled']:
+            conditions.append(dataframe['rsi'] < params['rsi']['value'])
+
+        # TRIGGERS
+        triggers = {
+            'lower_bb': dataframe['tema'] <= dataframe['blower'],
+            'faststoch10': (crossed_above(dataframe['fastd'], 10.0)),
+            'ao_cross_zero': (crossed_above(dataframe['ao'], 0.0)),
+            'ema5_cross_ema10': (crossed_above(dataframe['ema5'], dataframe['ema10'])),
+            'macd_cross_signal': (crossed_above(dataframe['macd'], dataframe['macdsignal'])),
+            'sar_reversal': (crossed_above(dataframe['close'], dataframe['sar'])),
+            'stochf_cross': (crossed_above(dataframe['fastk'], dataframe['fastd'])),
+            'ht_sine': (crossed_above(dataframe['htleadsine'], dataframe['htsine'])),
+        }
+        ...
+```
+
+
+### 2. Update the hyperopt config file
+Hyperopt is using a dedicated config file. At this moment hyperopt 
+cannot use your config file. It is also made on purpose to allow you
+testing your strategy with different configurations.
+
+The Hyperopt configuration is located in 
+[freqtrade/optimize/hyperopt_conf.py](https://github.com/gcarq/freqtrade/blob/develop/freqtrade/optimize/hyperopt_conf.py).
+
+
+## Advanced notions
+### Understand the Guards and Triggers
+When you need to add the new guards and triggers to be hyperopt 
+parameters, you do this by adding them into the [SPACE dict](https://github.com/gcarq/freqtrade/blob/develop/freqtrade/optimize/hyperopt.py#L47-L94).
+
+If it's a trigger, you add one line to the 'trigger' choice group and that's it.
+
+If it's a guard, you will add a line like this:
+```
+'rsi': hp.choice('rsi', [
+    {'enabled': False},
+    {'enabled': True, 'value': hp.quniform('rsi-value', 20, 40, 1)}
+]),
+```
+This says, "*one of guards is RSI, it can have two values, enabled or 
+disabled. If it is enabled, try different values for it between 20 and 40*".
+
+So, the part of the strategy builder using the above setting looks like 
+this:
+```
+if params['rsi']['enabled']:
+    conditions.append(dataframe['rsi'] < params['rsi']['value'])
+```
+It checks if Hyperopt wants the RSI guard to be enabled for this 
+round `params['rsi']['enabled']` and if it is, then it will add a 
+condition that says RSI must be < than the value hyperopt picked 
+for this evaluation, that is given in the `params['rsi']['value']`.
+
+That's it. Now you can add new parts of strategies to Hyperopt and it 
+will try all the combinations with all different values in the search 
+for best working algo.
+
+
+### Add a new Indicators
+If you want to test an indicator that isn't used by the bot currently, 
+you need to add it to 
+[freqtrade/analyze.py](https://github.com/gcarq/freqtrade/blob/develop/freqtrade/analyze.py#L40-L70)
+inside the `populate_indicators` function.
+
+## Execute Hyperopt
+Once you have updated your hyperopt configuration you can run it. 
+Because hyperopt tries a lot of combination to find the best parameters
+it will take time you will have the result (more than 30 mins).
+
+We strongly recommend to use `screen` to prevent any connection loss.
+```bash
+python3 ./freqtrade/main.py -c config.json hyperopt
+```
+
+### Execute hyperopt with different ticker-data source
+If you would like to learn parameters using an alternate ticke-data that
+you have on-disk, use the --datadir PATH option. Default hyperopt will
+use data from directory freqtrade/tests/testdata.
+
+### Hyperopt with MongoDB
+Hyperopt with MongoDB, is like Hyperopt under steroids. As you saw by
+executing the previous command is the execution takes a long time. 
+To accelerate it you can use hyperopt with MongoDB.
+
+To run hyperopt with MongoDb you will need 3 terminals.
+
+**Terminal 1: Start MongoDB**
+```bash
+cd <freqtrade> 
+source .env/bin/activate
+python3 scripts/start-mongodb.py
+```
+
+**Terminal 2: Start Hyperopt worker**
+```bash
+cd <freqtrade> 
+source .env/bin/activate
+python3 scripts/start-hyperopt-worker.py
+```
+
+**Terminal 3: Start Hyperopt with MongoDB**
+```bash
+cd <freqtrade> 
+source .env/bin/activate
+python3 ./freqtrade/main.py -c config.json hyperopt --use-mongodb
+```
+
+**Re-run an Hyperopt**
+To re-run Hyperopt you have to delete the existing MongoDB table.
+```bash
+cd <freqtrade> 
+rm -rf .hyperopt/mongodb/
+```
+
+## Understand the hyperopts result 
+Once Hyperopt is completed you can use the result to adding new buy 
+signal. Given following result from hyperopt:
+```
+Best parameters:
+{
+    "adx": {
+        "enabled": true,
+        "value": 15.0
+    },
+    "fastd": {
+        "enabled": true,
+        "value": 40.0
+    },
+    "green_candle": {
+        "enabled": true
+    },
+    "mfi": {
+        "enabled": false
+    },
+    "over_sar": {
+        "enabled": false
+    },
+    "rsi": {
+        "enabled": true,
+        "value": 37.0
+    },
+    "trigger": {
+        "type": "lower_bb"
+    },
+    "uptrend_long_ema": {
+        "enabled": true
+    },
+    "uptrend_short_ema": {
+        "enabled": false
+    },
+    "uptrend_sma": {
+        "enabled": false
+    }
+}
+
+Best Result:
+  2197 trades. Avg profit  1.84%. Total profit  0.79367541 BTC. Avg duration 241.0 mins.
+```
+
+You should understand this result like:
+- You should **consider** the guard "adx" (`"adx"` is `"enabled": true`) 
+and the best value is `15.0` (`"value": 15.0,`)
+- You should **consider** the guard "fastd" (`"fastd"` is `"enabled": 
+true`) and the best value is `40.0` (`"value": 40.0,`)
+- You should **consider** to enable the guard "green_candle" 
+(`"green_candle"` is `"enabled": true`) but this guards as no 
+customizable value.
+- You should **ignore** the guard "mfi" (`"mfi"` is `"enabled": false`)
+- and so on...
+
+
+You have to look from 
+[freqtrade/optimize/hyperopt.py](https://github.com/gcarq/freqtrade/blob/develop/freqtrade/optimize/hyperopt.py#L170-L200) 
+what those values match to.   
+  
+So for example you had `adx:` with the `value: 15.0` so we would look 
+at `adx`-block from 
+[freqtrade/optimize/hyperopt.py](https://github.com/gcarq/freqtrade/blob/develop/freqtrade/optimize/hyperopt.py#L178-L179). 
+That translates to the following code block to 
+[analyze.populate_buy_trend()](https://github.com/gcarq/freqtrade/blob/develop/freqtrade/analyze.py#L73)
+```
+(dataframe['adx'] > 15.0)
+```
+  
+So translating your whole hyperopt result to as the new buy-signal 
+would be the following:
+```
+def populate_buy_trend(dataframe: DataFrame) -> DataFrame:
+    dataframe.loc[
+        (
+            (dataframe['adx'] > 15.0) & # adx-value
+            (dataframe['fastd'] < 40.0) & # fastd-value
+            (dataframe['close'] > dataframe['open']) & # green_candle
+            (dataframe['rsi'] < 37.0) & # rsi-value
+            (dataframe['ema50'] > dataframe['ema100']) # uptrend_long_ema
+        ),
+        'buy'] = 1
+    return dataframe
+```
+
+## Next step
+Now you have a perfect bot and want to control it from Telegram. Your
+next step is to learn the [Telegram usage](https://github.com/gcarq/freqtrade/blob/develop/docs/telegram-usage.md).

+### 1. Prepare the bot
+1. Clone the git
+```bash
+git clone https://github.com/gcarq/freqtrade.git
+```
+2. (Optional) Checkout the develop branch
+```bash
+git checkout develop
+```
+3. Go into the new directory
+```bash
+cd freqtrade
+```
+4. Copy `config.sample` to `config.json`
+```bash
+cp config.json.example config.json
+```
+To edit the config please refer to the [Bot Configuration](https://github.com/gcarq/freqtrade/blob/develop/docs/configuration.md) page
+5. Create your DB file (Optional, the bot will create it if it is missing)
+```bash
+# For Production
+touch tradesv3.sqlite
+
+# For Dry-run
+touch tradesv3.dryrun.sqlite
+```
+
+### 2. Build the docker image
+```bash
+cd freqtrade
+docker build -t freqtrade .
+```
+
+For security reasons, your configuration file will not be included in the
+image, you will need to bind mount it. It is also advised to bind mount
+a sqlite database file (see the "5. Run a restartable docker image"
+section) to keep it between  updates.
+
+### 3. Verify the docker image
+After build process you can verify that the image was created with:
+```
+docker images
+```
+
+### 4. Run the docker image
+You can run a one-off container that is immediately deleted upon exiting with
+the following command (config.json must be in the current working directory):
+
+```
+docker run --rm -v `pwd`/config.json:/freqtrade/config.json -it freqtrade
+```
+
+In this example, the database will be created inside the docker instance
+and will be lost when you will refresh your image.
+
+### 5. Run a restartable docker image
+To run a restartable instance in the background (feel free to place your
+configuration and database files wherever it feels comfortable on your
+filesystem).
+
+**5.1. Move your config file and database**
+```bash
+mkdir ~/.freqtrade
+mv config.json ~/.freqtrade
+mv tradesv3.sqlite ~/.freqtrade
+```
+
+**5.2. Run the docker image**
+```bash
+docker run -d \
+  --name freqtrade \
+  -v ~/.freqtrade/config.json:/freqtrade/config.json \
+  -v ~/.freqtrade/tradesv3.sqlite:/freqtrade/tradesv3.sqlite \
+  freqtrade
+```
+If you are using `dry_run=True` it's not necessary to mount
+`tradesv3.sqlite`, but you can mount `tradesv3.dryrun.sqlite` if you
+plan to use the dry run mode with the param `--dry-run-db`.
+
+
+### 6. Monitor your Docker instance
+You can then use the following commands to monitor and manage your container:
+
+```bash
+docker logs freqtrade
+docker logs -f freqtrade
+docker restart freqtrade
+docker stop freqtrade
+docker start freqtrade
+```
+
+You do not need to rebuild the image for configuration changes, it will
+suffice to edit `config.json` and restart the container.

+
+## Setup your Bittrex account
+*To be completed, please feel free to complete this section.*
+
+## Setup your Telegram bot
+The only things you need is a working Telegram bot and its API token.
+Below we explain how to create your Telegram Bot, and how to get your
+Telegram user id.
+
+### 1. Create your instagram bot
+**1.1. Start a chat with https://telegram.me/BotFather**  
+**1.2. Send the message** `/newbot`  
+*BotFather response:*
+```
+Alright, a new bot. How are we going to call it? Please choose a name for your bot.
+```
+**1.3. Choose the public name of your bot (e.g "`Freqtrade bot`")**  
+*BotFather response:*
+```
+Good. Now let's choose a username for your bot. It must end in `bot`. Like this, for example: TetrisBot or tetris_bot.
+```
+**1.4. Choose the name id of your bot (e.g "`My_own_freqtrade_bot`")**  
+**1.5. Father bot will return you the token (API key)**  
+Copy it and keep it you will use it for the config parameter `token`.  
+*BotFather response:*
+```
+Done! Congratulations on your new bot. You will find it at t.me/My_own_freqtrade_bot. You can now add a description, about section and profile picture for your bot, see /help for a list of commands. By the way, when you've finished creating your cool bot, ping our Bot Support if you want a better username for it. Just make sure the bot is fully operational before you do this.
+
+Use this token to access the HTTP API:
+521095879:AAEcEZEL7ADJ56FtG_qD0bQJSKETbXCBCi0
+
+For a description of the Bot API, see this page: https://core.telegram.org/bots/api
+```
+
+### 2. Get your user id
