基于RSI的自动挂单策略

当相对强弱指标（RSI）在超买或超卖区域连续保持指定数量的K线时，本策略会自动放置限价挂单。

当RSI连续 MatchCount 根K线低于超卖水平时，在收盘价下方 PendingOffset 个价格点处挂出买入限价单；当RSI连续位于超买水平以上时，在收盘价上方同样距离处挂出卖出限价单。

参数

  • RsiPeriod – RSI的计算周期。
  • RsiOverbought – 判断超买区域的水平。
  • RsiOversold – 判断超卖区域的水平。
  • PendingOffset – 挂单距离收盘价的偏移量（价格点）。
  • MatchCount – 触发挂单所需的连续K线数量。
  • CandleType – 用于分析的K线周期。

默认设置仿照原始MQL脚本并使用4小时K线。
