|

|
|
BaseVolume (Default 20 currencies)
|
|
```
|
|
|
|
### 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 --strategy?
|
|
This parameter will allow you to load your custom strategy class.
|
|
Per default without `--strategy` or `-s` the bot will load the
|
|
`DefaultStrategy` included with the bot (`freqtrade/strategy/default_strategy.py`).
|
|
|
|
The bot will search your strategy file within `user_data/strategies` and `freqtrade/strategy`.
|
|
|
|
To load a strategy, simply pass the class name (e.g.: `CustomStrategy`) in this parameter.
|
|
|
|
**Example:**
|
|
In `user_data/strategies` you have a file `my_awesome_strategy.py` which has
|
|
a strategy class called `AwesomeStrategy` to load it:
|
|
```bash
|
|
python3 ./freqtrade/main.py --strategy AwesomeStrategy
|
|
```
|
|
|
|
If the bot does not find your strategy file, it will display in an error
|
|
message the reason (File not found, or errors in your code).
|
|
|
|
Learn more about strategy file in [optimize your bot](https://github.com/gcarq/freqtrade/blob/develop/docs/bot-optimization.md).
|
|
|
|
### How to use --strategy-path?
|
|
This parameter allows you to add an additional strategy lookup path, which gets
|
|
checked before the default locations (The passed path must be a folder!):
|
|
```bash
|
|
python3 ./freqtrade/main.py --strategy AwesomeStrategy --strategy-path /some/folder
|
|
```
|
|
|
|
#### How to install a strategy?
|
|
This is very simple. Copy paste your strategy file into the folder
|
|
`user_data/strategies` or use `--strategy-path`. And voila, the bot is ready to use it.
|
|
|
|
### 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 (default: '5m')
|
|
--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 the exchange. 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).
