标题：请老师检查公式，K线图为什么没有显示多单信号的？

if CROSS(wMA(CLOSE,n2),wMA(CLOSE,n)) then begin
sell(1,1,market);
buyshort(1,1,market);
end
if CROSS(wMA(CLOSE,n),wMA(CLOSE,n2)) then begin
sellshort(1,1,market);
buy(1,1,market);
end

改成这样

根据先平后开的原则写

sell(CROSS(wMA(CLOSE,n2),wMA(CLOSE,n)));
buyshort(CROSS(wMA(CLOSE,n2),wMA(CLOSE,n)),1);
sellshort(CROSS(wMA(CLOSE,n),wMA(CLOSE,n2)));
buy(CROSS(wMA(CLOSE,n),wMA(CLOSE,n2)),1);
