1. 新建策略，对应的策略的文件路径，user_data/strategies/test.py
freqtrade new-strategy --strategy test
2. 附加参数，低级模板
freqtrade new-strategy --strategy test --template minimal
3. 高级模板
freqtrade new-strategy --strategy test --template advanced
注意事项，不要使用未来数据，比如当天的价格最低点。
注意事项，尽力采用矢量化操作
INTERFACE_VERSION，这个是机器人使用的接口版本，默认是 3
INTERFACE_VERSION = 3
启用做空
can_short: bool = False
最小投资回报率，这个命令是指在退出之前应该达到的最小回报率，即利润达到百分之 4 时退出，30 分钟后 达到百分之 2 退出，60 分钟后达到百分之 1 退出，不想启用 roi，可将其设置为空
minimal_roi = {
"60": 0.01,
"30": 0.02,
"0": 0.04
}
同样也可将 ROI 根据时间范围去设置
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
}
设置止损百分之 10
stoploss = -0.10
时间范围
timeframe = '5m'
策略的启动时期，策略的启动时期，是指在这个时间内，指标的计算会有误差，但具体的启动时间是多长时间，为了解决这个问题，给策略分配 startup_candle_count 这个属性，该值是计算指标所需要的最大周期，例如
startup_candle_count = 100
dataframe['ema100'] = ta.EMA(dataframe, timeperiod=100)
额外的信息对，这些信息对可能对策略有用，但不会被用来交易
