根据视频课写了EMA的双均线系统，但是图上没有信号，麻烦看看

学习视频课的双均线交易系统，写了EMA的双均线交易系统，但是没有信号，麻烦看看。Params Numeric Length1(5); Numeric Length2(20);Vars series<Numeric> EMA1; series<Numeric> EMA2; series<Bool> bool_crossover; series<Bool> bool_crossunder;Events OnBar(ArrayRef<Integer> indexs) { //双EMA均线用收盘价计算两根均线 PlotNumeric("EMA1",XAverage(Close, Length1)); PlotNumeric("EMA2",XAverage(Close, Length2)); //金叉和死叉状态 bool_crossover = EMA1[1] <= EMA2[1] and EMA1 > EMA2; bool_crossunder = EMA1[1] >= EMA2[1] and EMA1 < EMA2; If(bool_crossover[1]) { Buy(1,Open); } If(bool_crossunder[1]) { SellShort(1,Open); } }

知道错误原因了，ema1和ema2的两行代码漏掉了

回复：😅

bool_crossover = EMA1[1] <= EMA2[1] and EMA1 > EMA2; bool_crossunder = EMA1[1] >= EMA2[1] and EMA1 < EMA2;改成：bool_crossover = EMA1[12] <= EMA2[12] and EMA1[1] > EMA2[1]; bool_crossunder = EMA1[21] >= EMA2[12] and EMA1[1] < EMA2[1];再试试。

回复：bool_crossover = EMA1[1] <= EMA2[1] and EMA1 > EMA2; bool_crossunder = EMA1[1] >= EMA2[1] and EMA1 < EMA2; 改成：bool_crossover = EMA1[2] <= EMA2[2] and EMA1[1] > EMA2[1]; bool_crossunder = EMA1[2] >= EMA2[2] and EMA1[1] < EMA2[1];再试试。以这个为准

回复：bool_crossover = EMA1[1] <= EMA2[1] and EMA1 > EMA2; bool_crossunder = EMA1[1] >= EMA2[1] and EMA1 < EMA2; 改成：bool_crossover = EMA1[2] <= EMA2[2] and EMA1[1] > EMA2[1]; bool_crossunder = EMA1[2] >= EMA2[2] and EMA1[1] < EMA2[1];再试试。以这个为准

回复：谢谢回复，我试了一下，还是不行😭
