Geedo 策略

基于时间的策略：在指定的小时比较两根过去K线的开盘价。如果较早的K线高于较新的K线并超过阈值，则开空单；如果较新的K线高于较早的K线，则开多单。每笔交易都有固定的止损和止盈，并在达到最大持仓时间后强制平仓。

详情

  • 入场条件：在 TradeTime 比较 T1 与 T2 根之前的开盘价。如果 Open[T1] - Open[T2] 大于 DeltaShort 则做空；如果 Open[T2] - Open[T1] 大于 DeltaLong 则做多。
  • 多空方向：双向。
  • 退出条件：止损、止盈或持仓超过 MaxOpenTime 小时。
  • 止损：固定点差。
  • 默认值：
    • TakeProfitLong = 39
    • StopLossLong = 147
    • TakeProfitShort = 15
    • StopLossShort = 6000
    • TradeTime = 18
    • T1 = 6
    • T2 = 2
    • DeltaLong = 6
    • DeltaShort = 21
    • Volume = 0.01
    • MaxOpenTime = 504
  • 过滤器：
    • 类型: 时间
    • 方向: 双向
    • 指标: 无
    • 止损: 固定
    • 复杂度: 初级
    • 时间框架: 日内 (1小时)
    • 季节性: 无
    • 神经网络: 无
    • 背离: 无
    • 风险等级: 中等
