主题：老师帮我看看

老师好 我这样为什么不能实现每个信号下只开平仓一次呢 只要止盈或者止损后就会继续开平仓  麻烦老师帮忙给改正一下 谢谢   SS:=1;//ss
if B8<=0 then begin,

sellshort(1,holding,thisclose),orderqueue;
buy(holding=0 and bj=0,ss,thisclose),orderqueue;
end
if bj=1 and B8<=0 and holding=0 and exitbars>1 then begin
buy(1,ss,thisclose);
bj:=0;
end

if B8>0 then begin

sell(1,holding,thisclose),orderqueue;
buyshort(holding=0 and bj=0,ss,thisclose),orderqueue;
end
if bj=1 and B8>0 and holding=0 and exitbars>1 then begin
buyshort(1,ss,thisclose);
bj:=0;
end
