CCI + EMA 策略（百分比或 ATR TP/SL）

该策略将商品通道指数（CCI）与可选的 EMA 趋势过滤和 RSI 确认结合使用。 当 CCI 离开极端区域并且可选过滤器允许时开仓。 止盈和止损可以按入场价的百分比计算，也可以使用 ATR 及风险收益比来确定。

细节

  • 入场条件：
    • 多头： CCI 向上穿越超卖水平，价格高于 EMA（如启用），RSI 低于超卖（如启用）。
    • 空头： CCI 向下穿越超买水平，价格低于 EMA（如启用），RSI 高于超买（如启用）。
  • 出场条件：
    • 达到止盈或止损。
    • 多头仓位在 CCI 向上穿越超买水平时平仓。
    • 空头仓位在 CCI 向下穿越超卖水平时平仓。

默认参数基于原始脚本。
