Minimum return on investment, this command refers to the minimum return that should be achieved before exiting, that is, exit when profit reaches 4%, exit when it reaches 2% after 30 minutes, and exit when it reaches 1% after 60 minutes. If you do not want to enable roi, you can set it to empty
minimal_roi = {
"60": 0.01,
"30": 0.02,
"0": 0.04
}
ROI can also be set based on time range
from freqtrade.exchange import timeframe_to_minutes
class AwesomeStrategy(IStrategy):
timeframe = "1d"
timeframe_mins = timeframe_to_minutes(timeframe)
minimal_roi = {
"0": 0.05, # 5% for the first 3 candles
str(timeframe_mins * 3): 0.02, # 2% after 3 candles
str(timeframe_mins * 6): 0.01, # 1% After 6 candles
}
Set stop loss at 10%
stoploss = -0.10
Time range
timeframe = '5m'
The startup period of the strategy refers to the time during which the calculation of indicators may have errors, but the specific startup time is how long. To solve this problem, assign the attribute startup_candle_count to the strategy, which is the maximum period required for calculating indicators, for example
startup_candle_count = 100
dataframe['ema100'] = ta.EMA(dataframe, timeperiod=100)
Informative pairs, this information may be useful for the strategy but will not be used for trading
