+## A note on Binance
+
+For Binance, please add `"BNB/<STAKE>"` to your blacklist to avoid issues.
+Accounts having BNB accounts use this to pay for fees - if your first trade happens to be on `BNB`, further trades will consume this position and make the initial BNB order unsellable as the expected amount is not there anymore.

+Go to the [trailing stoploss Documentation](stoploss.md) for details on trailing stoploss.
+
 ### 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 process_throttle_secs
+
 `process_throttle_secs` is an optional field that defines in seconds how long the bot should wait
 before asking the strategy if we should buy or a sell an asset. After each wait period, the strategy is asked again for
 every opened trade wether or not we should sell, and for all the remaining pairs (either the dynamic list of pairs or
 the static list of pairs) if we should buy.
 
 ### 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 exchange.name?
+
 Freqtrade is based on [CCXT library](https://github.com/ccxt/ccxt) that supports 115 cryptocurrency
 exchange markets and trading APIs. The complete up-to-date list can be found in the
 [CCXT repo homepage](https://github.com/ccxt/ccxt/tree/master/python). However, the bot was tested
 with only Bittrex and Binance.
 
 The bot was tested with the following exchanges:
+
 - [Bittrex](https://bittrex.com/): "bittrex"
 - [Binance](https://www.binance.com/): "binance"
 
 Feel free to test other exchanges and submit your PR to improve the bot.
 
 ### What values for fiat_display_currency?
+
 `fiat_display_currency` set the base currency to use for the conversion from coin to fiat in Telegram.
 The valid values 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".
 In addition to central bank currencies, a range of cryto currencies are supported.
 The valid values are: "BTC", "ETH", "XRP", "LTC", "BCH", "USDT".
 
 ## 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 and specify db_url for a persistent db
+
 ```json
 "dry_run": true,
 "db_url": "sqlite///tradesv3.dryrun.sqlite",
 ```
 
 3. Remove your Exchange 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 and don't forget to adapt your database URL if set
+
 ```json

+
+### Embedding Strategies
+
+FreqTrade provides you with with an easy way to embed the strategy into your configuration file. 
+This is done by utilizing BASE64 encoding and providing this string at the strategy configuration field,
+in your chosen config file.
+
+##### Encoding a string as BASE64
+
+This is a quick example, how to generate the BASE64 string in python
+
+```python
+from base64 import urlsafe_b64encode
+
+with open(file, 'r') as f:
+    content = f.read()
+content = urlsafe_b64encode(content.encode('utf-8'))
+```
+
+The variable 'content', will contain the strategy file in a BASE64 encoded form. Which can now be set in your configurations file as following
+
+```json
+"strategy": "NameOfStrategy:BASE64String"
+```
+
+Please ensure that 'NameOfStrategy' is identical to the strategy name!

+## Solving a Mystery
-```python
-def populate_buy_trend(dataframe: DataFrame) -> DataFrame:
-    dataframe.loc[
-        (dataframe['rsi'] < 35) &
-        (dataframe['adx'] > 65),
-        'buy'] = 1
 
-    return dataframe
+Let's say you are curious: should you use MACD crossings or lower Bollinger 
-```
+Bands to trigger your buys. And you also wonder should you use RSI or ADX to 
+help with those buy decisions. If you decide to use RSI or ADX, which values 
+should I use for them? So let's use hyperparameter optimization to solve this 
+mystery.
 
-Your hyperopt file must contain `guards` to find the right value for 
+We will start by defining a search space:
-`(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 your strategy file 
-will 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': 'stochf_cross'},
-        {'type': 'ht_sine'},
-    ]),
-}
-
-... 
-
-def populate_buy_trend(self, dataframe: DataFrame) -> DataFrame:
-        conditions = []
-        # GUARDS AND TRENDS
-        if params['adx']['enabled']:

-
-
-### 2. Update the hyperopt config file
-Hyperopt is using a dedicated config file. Currently 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 
-[user_data/hyperopt_conf.py](https://github.com/freqtrade/freqtrade/blob/develop/user_data/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 [hyperopt_space()](https://github.com/freqtrade/freqtrade/blob/develop/user_data/strategies/test_strategy.py#L244-L297).
-
-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 the 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']:
+    def indicator_space() -> List[Dimension]:
-    conditions.append(dataframe['rsi'] < params['rsi']['value'])
+        """
+        Define your Hyperopt space for searching strategy parameters
+        """
+        return [
+            Integer(20, 40, name='adx-value'),
+            Integer(20, 40, name='rsi-value'),
+            Categorical([True, False], name='adx-enabled'),
+            Categorical([True, False], name='rsi-enabled'),
+            Categorical(['bb_lower', 'macd_cross_signal'], name='trigger')
+        ]
 ```
 
-It checks if Hyperopt wants the RSI guard to be enabled for this 
+Above definition says: I have five parameters I want you to randomly combine 
-round `params['rsi']['enabled']` and if it is, then it will add a 
+to find the best combination. Two of them are integer values (`adx-value` 
-condition that says RSI must be smaller than the value hyperopt picked 
+and `rsi-value`) and I want you test in the range of values 20 to 40.
-for this evaluation, which is given in the `params['rsi']['value']`.
+Then we have three category variables. First two are either `True` or `False`.
+We use these to either enable or disable the ADX and RSI guards. The last
+one we call `trigger` and use it to decide which buy trigger we want to use.
 
-That's it. Now you can add new parts of strategies to Hyperopt and it 
+So let's write the buy strategy using these values:
-will try all the combinations with all different values in the search 
-for best working algo.
 
+```
+        def populate_buy_trend(dataframe: DataFrame) -> DataFrame:
+            conditions = []
+            # GUARDS AND TRENDS
+            if 'adx-enabled' in params and params['adx-enabled']:
+                conditions.append(dataframe['adx'] > params['adx-value'])
+            if 'rsi-enabled' in params and params['rsi-enabled']:
+                conditions.append(dataframe['rsi'] < params['rsi-value'])
 
-### Add a new Indicators
+            # TRIGGERS
-If you want to test an indicator that isn't used by the bot currently, 
+            if params['trigger'] == 'bb_lower':
-you need to add it to the `populate_indicators()` method in `hyperopt.py`.
+                conditions.append(dataframe['close'] < dataframe['bb_lowerband'])
+            if params['trigger'] == 'macd_cross_signal':
+                conditions.append(qtpylib.crossed_above(
+                    dataframe['macd'], dataframe['macdsignal']
+                ))
+
+            dataframe.loc[
+                reduce(lambda x, y: x & y, conditions),
+                'buy'] = 1
+
+            return dataframe
+
+        return populate_buy_trend
+```
+
+Hyperopting will now call this `populate_buy_trend` as many times you ask it (`epochs`)
+with different value combinations. It will then use the given historical data and make
+buys based on the buy signals generated with the above function and based on the results
+it will end with telling you which paramter combination produced the best profits.
+
+The search for best parameters starts with a few random combinations and then uses a 
+regressor algorithm (currently ExtraTreesRegressor) to quickly find a parameter combination
+that minimizes the value of the objective function `calculate_loss` in `hyperopt.py`.
+
+The above setup expects to find ADX, RSI and Bollinger Bands in the populated indicators.
+When you want to test an indicator that isn't used by the bot currently, remember to 
+add it to the `populate_indicators()` method in `hyperopt.py`.

+- The buy trigger that worked best was `bb_lower`.
-and the best value is `15.0` (`"value": 15.0,`)

+
+## You should now be ready to test your sandbox
+
+Ensure Freqtrade logs show the sandbox URL, and trades made are shown in sandbox.
+** Typically the  BTC/USD has the most activity in sandbox to test against.
+
+## GDAX - Old Candles problem
+
+It is my experience that GDAX sandbox candles may be 20+- minutes out of date. This can cause trades to fail as one of Freqtrades safety checks.
+
+To disable this check, add / change the `"outdated_offset"` parameter in the exchange section of your configuration to adjust for this delay.
+Example based on the above configuration:
+
+```json
+  "exchange": {
+        "name": "gdax",

+# Stop Loss support
+
+At this stage the bot contains the following stoploss support modes:
+
+1. static stop loss, defined in either the strategy or configuration
+2. trailing stop loss, defined in the configuration
+3. trailing stop loss, custom positive loss, defined in configuration
+
+## Static Stop Loss
+
+This is very simple, basically you define a stop loss of x in your strategy file or alternative in the configuration, which
+will overwrite the strategy definition. This will basically try to sell your asset, the second the loss exceeds the defined loss.
+
+## Trail Stop Loss
+
+The initial value for this stop loss, is defined in your strategy or configuration. Just as you would define your Stop Loss normally.
+To enable this Feauture all you have to do is to define the configuration element:
+
+``` json
+"trailing_stop" : True
+```
+
+This will now activate an algorithm, which automatically moves your stop loss up every time the price of your asset increases.
+
+For example, simplified math,
+
+* you buy an asset at a price of 100$
+* your stop loss is defined at 2%
+* which means your stop loss, gets triggered once your asset dropped below 98$
+* assuming your asset now increases to 102$
+* your stop loss, will now be 2% of 102$ or 99.96$
+* now your asset drops in value to 101$, your stop loss, will still be 99.96$
+
+basically what this means is that your stop loss will be adjusted to be always be 2% of the highest observed price
+
+### Custom positive loss
+
+Due to demand, it is possible to have a default stop loss, when you are in the red with your buy, but once your profit surpasses a certain percentage,
+the system will utilize a new stop loss, which can be a different value. For example your default stop loss is 5%, but once you have 1.1% profit,
+it will be changed to be only a 1% stop loss, which trails the green candles until it goes below them.
+
+Both values can be configured in the main configuration file and requires `"trailing_stop": true` to be set to true.
+
+``` json
+    "trailing_stop_positive":  0.01,
+    "trailing_stop_positive_offset":  0.011,
+```
+
+The 0.01 would translate to a 1% stop loss, once you hit 1.1% profit.
+
+You should also make sure to have this value higher than your minimal ROI, otherwise minimal ROI will apply first and sell your trade.

+# Webhook usage
+
+This page explains how to configure your bot to talk to webhooks.
+
+## Configuration
+
+Enable webhooks by adding a webhook-section to your configuration file, and setting `webhook.enabled` to `true`.
+
+Sample configuration (tested using IFTTT).
+
+```json
+  "webhook": {
+        "enabled": true,
+        "url": "https://maker.ifttt.com/trigger/<YOUREVENT>/with/key/<YOURKEY>/",
+        "webhookbuy": {
+            "value1": "Buying {pair}",
+            "value2": "limit {limit:8f}",
+            "value3": "{stake_amount:8f} {stake_currency}"
+        },
+        "webhooksell": {
+            "value1": "Selling {pair}",
+            "value2": "limit {limit:8f}",
+            "value3": "profit: {profit_amount:8f} {stake_currency}"
+        },
+        "webhookstatus": {
+            "value1": "Status: {status}",
+            "value2": "",
+            "value3": ""
+        }
+    },
+```
+
+The url in `webhook.url` should point to the correct url for your webhook. If you're using [IFTTT](https://ifttt.com) (as shown in the sample above) please insert our event and key to the url.
+
+Different payloads can be configured for different events. Not all fields are necessary, but you should configure at least one of the dicts, otherwise the webhook will never be called.
+
+### Webhookbuy
+
+The fields in `webhook.webhookbuy` are filled when the bot executes a buy. Parameters are filled using string.format.
+Possible parameters are:
+
+* exchange
+* pair
+* market_url
+* limit
+* stake_amount
+* stake_amount_fiat
+* stake_currency
+* fiat_currency
+
+### Webhooksell
+
+The fields in `webhook.webhooksell` are filled when the bot sells a trade. Parameters are filled using string.format.
+Possible parameters are:
+
+* exchange
+* pair
+* gain
+* market_url
+* limit
+* amount
+* open_rate
+* current_rate
+* profit_amount
+* profit_percent
+* profit_fiat
+* stake_currency
+* fiat_currency
+
+### Webhookstatus
+
+The fields in `webhook.webhookstatus` are used for regular status messages (Started / Stopped / ...). Parameters are filled using string.format.
+
+The only possible value here is `{status}`.
