Bot Optimization

This page explains where to customize your strategies, and add new indicators.

• Where is the default strategy

Since the version 0.16.0 the bot allows using custom strategy file.

Install a custom strategy file

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

Let assume you have a class called AwesomeStrategy in the file awesome-strategy.py:

1. Move your file into user_data/strategies (you should have user_data/strategies/awesome-strategy.py
2. Start the bot with the param --strategy AwesomeStrategy (the parameter is the class name)

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

Change your strategy

The bot includes a default strategy file. However, we recommend you to use your own file to not have to lose your parameters every time the default strategy file will be updated on Github. Put your custom strategy file into the folder user_data/strategies.

A strategy file contains all the information needed to build a good strategy:

• Buy strategy rules
• Sell strategy rules
• Minimal ROI recommended
• Stoploss recommended
• Hyperopt parameter

The bot also include a sample strategy called TestStrategy you can update: user_data/strategies/test_strategy.py. You can test it with the parameter: --strategy TestStrategy

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

Specify custom strategy location

If you want to use a strategy from a different folder you can pass --strategy-path

python3 ./freqtrade/main.py --strategy AwesomeStrategy --strategy-path /some/folder

For the following section we will use the user_data/strategies/test_strategy.py file as reference.

Buy strategy

Edit the method populate_buy_trend() into your strategy file to update your buy strategy.

Sample from user_data/strategies/test_strategy.py:

def populate_buy_trend(self, 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['adx'] > 30) &
            (dataframe['tema'] <= dataframe['blower']) &
            (dataframe['tema'] > dataframe['tema'].shift(1))
        ),
        'buy'] = 1

    return dataframe

Sell strategy

Edit the method populate_sell_trend() into your strategy file to update your sell strategy.

Sample from user_data/strategies/test_strategy.py:

def populate_sell_trend(self, 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[
        (
            (dataframe['adx'] > 70) &
            (dataframe['tema'] > dataframe['blower']) &
            (dataframe['tema'] < dataframe['tema'].shift(1))
        ),
        'sell'] = 1
    return dataframe

Add more Indicator

As you have seen, buy and sell strategies need indicators. You can add more indicators by extending the list contained in the method populate_indicators() from your strategy file.

Sample:

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

Want more indicators example?
Look into the user_data/strategies/test_strategy.py.
Then uncomment indicators you need.

Where is the default strategy?

The default buy strategy is located in the file freqtrade/default_strategy.py.
