RSI Automated Strategy

利用相对强弱指数（RSI）在极度超卖和超买状态下进行交易的动量策略。 当RSI跌破超卖水平时开多仓，当RSI升破超买水平时开空仓。 当RSI回到中间阈值或触发止损、止盈或追踪止损时平仓。

细节

  • 入场条件：RSI跌破 Oversold 做多或升破 Overbought 做空。
  • 多空方向：双向。
  • 出场条件：RSI触及 ExitLevel、止损、止盈或追踪止损。
  • 止损：是，固定止损、止盈以及可选的追踪止损。
  • 默认值：
    • RsiPeriod = 14
    • Overbought = 75
    • Oversold = 25
    • ExitLevel = 50
    • StopLossPoints = 50
    • TakeProfitPoints = 150
    • TrailingStopPoints = 25
    • CandleType = TimeSpan.FromMinutes(1)
  • 筛选：
    • 分类：振荡指标
    • 方向：双向
    • 指标：RSI
    • 止损：是
    • 复杂度：基础
    • 时间框架：日内 (1m)
    • 季节性：否
    • 神经网络：否
    • 背离：否
    • 风险等级：中等
