Charles EMA RSI 策略

该策略仿照 Charles 智能交易系统，将指数移动平均线 (EMA)、RSI 滤波和追踪止损结合使用，可做多也可做空，并自动保护持仓。

策略在选定的时间框架上监控快慢 EMA。当快速 EMA 向上穿越慢速 EMA 且 RSI 高于 55 时，开多仓；当快速 EMA 向下穿越慢速 EMA 且 RSI 低于 45 时，开空仓。入场后，追踪止损跟随价格锁定利润，同时内置的止损和止盈负责风险控制。

细节

  • 入场条件：
    • 多头：快速 EMA 上穿 慢速 EMA 且 RSI > 55。
    • 空头：快速 EMA 下穿 慢速 EMA 且 RSI < 45。
  • 多/空：双向。
  • 出场条件：
    • 追踪止损；
    • 止损或止盈。
  • 止损：使用内置保护并带有追踪。
  • 默认值：
    • FastPeriod = 18
    • SlowPeriod = 60
    • RsiPeriod = 14
    • TakeProfit = 0.02
    • StopLoss = 0.008
    • TrailStart = 0.006
    • TrailOffset = 0.003
  • 过滤器：
    • 类别：趋势跟随
    • 方向：双向
    • 指标：多个
    • 止损：是
    • 复杂度：中等
    • 时间框架：默认 1 小时
    • 季节性：否
    • 神经网络：否
    • 背离：否
    • 风险等级：中等
