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
  -v, --verbose         be verbose
  --version             show program's version number and exit
  -c PATH, --config PATH
                        specify configuration file (default: config.json)
  -s PATH, --strategy PATH
                        specify strategy file (default:
                        freqtrade/strategy/default_strategy.py)
  --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.
  -dd PATH, --datadir PATH
                        path to backtest data (default freqdata/tests/testdata
  --dynamic-whitelist [INT]
                        dynamically generate and update whitelist based on 24h
                        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

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 file. Per default without --strategy or -s the bot will load the default_strategy included with the bot (freqtrade/strategy/default_strategy.py).

The bot will search your strategy file into user_data/strategies and freqtrade/strategy.

To load a strategy, simply pass the file name (without .py) in this parameters.

Example:
In user_data/strategies you have a file my_awesome_strategy.py to load it:

python3 ./freqtrade/main.py --strategy my_awesome_strategy

If the bot does not find your strategy file, it will fallback to the default_strategy.

How to install a strategy?

This is very simple. Copy paste your strategy file into the folder user_data/strategies. 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.

python3 ./freqtrade/main.py --dynamic-whitelist

Customize the number of currencies to retrieve
Get the 30 currencies based on BaseVolume.

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

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
