Ichimoku Chinkou Cross 策略

该策略基于 Ichimoku 的 Chinkou Span（滞后线）与价格的交叉进行交易。

策略逻辑

  • 做多： Chinkou 从下方上穿价格，且当前价格和 Chinkou 都在 Kumo 云之上，同时 RSI 高于 RsiBuyLevel。
  • 做空： Chinkou 从上方下穿价格，且当前价格和 Chinkou 都在 Kumo 云之下，同时 RSI 低于 RsiSellLevel。

策略通过 StartProtection 设置止损，并包含 Tenkan、Kijun、Senkou Span B 和 RSI 的参数。

参数

名称 描述 默认值
TenkanPeriod Tenkan-sen 周期 9
KijunPeriod Kijun-sen 周期 26
SenkouSpanPeriod Senkou Span B 周期 52
RsiPeriod RSI 计算周期 14
RsiBuyLevel 做多所需的最小 RSI 70
RsiSellLevel 做空所需的最大 RSI 30
StopLoss 止损百分比或数值 2%
CandleType 订阅蜡烛类型 5 分钟蜡烛
