Question

该机器人应该基于支撑和阻力来购买，止损基于移动平均线的支撑阻力。当我对其进行测试时，它不会做任何尝试。我该如何调试它以执行我想要的操作？

查看代码后，您是否有任何建议或批评意见？我试图尽我所能对代码进行注释。

检查并检查这段代码，直到您确定了解逻辑并使其正常工作为止

     //...
     if (CandleColor == "Green") //this one is NULL
        {
           PlacePendingOrder("Green", LotsToTrade, CandleSupport, PendingOrderExpirationSeconds);
           LastTradePlacedTimestamp = TimeCurrent();
        }
     }

     // short
     if ( CurrentPrice >= CandleResistance) 
     {
        if (CheckForTradeSetup() == "Red" )//this fn() returns "no-setup"
     //....

因此编辑CheckForTradeSetup（）函数并在检查颜色之前调用它，并且比较两个字符串也是一个非常糟糕的主意，因为它太慢了。 + 1/0 / -1或枚举甚至是颜色（== int）是首选
