该策略可在三种指标之间选择：简单移动平均线交叉、MACD 交叉或布林带突破。任意时刻仅启用一种模式，并可选择做多或做空方向。

参数

  • CandleType — K线周期。
  • Indicator — 使用的指标（MA、MACD、BB）。
  • Direction — 交易方向（Long 或 Short）。
  • MaLength — 移动平均线周期。
  • FastLength — MACD 快速 EMA 周期。
  • SlowLength — MACD 慢速 EMA 周期。
  • SignalLength — MACD 信号线周期。
  • BbLength — 布林带周期。
  • BbMultiplier — 布林带系数。
  • StartDate — 开始日期。
  • EndDate — 结束日期。
