请问为何图表上没有开平仓信号？　[金字塔]

这边是有信号的， 全是信号

用户代码是不是用的不是上面给的？用下面的代码呢？

a1:=valuewhen(todaybar=1,high);
a2:=valuewhen(todaybar=1,low);
a3:=time>=020000;
a4:=time<230000;
a5:=a3 and a4;
a6:=time>=002300;

//做多条件
if holding=0 and a5 and close>a1
then begin
buy(1,1,marketr);
end

//平多条件
if holding>0 and close<a2
then begin
sell(1,0,marketr);
end

//做空条件
if holding=0 and a5 and close<a2
then begin
buyshort(1,1,marketr);
end

//平空条件
if holding<0 and close>a1
then begin
sellshort(1,0,marketr);
end

//收盘平仓
if a6 and holding>0
then begin
sell(1,0,marketr);
end

if a6 and holding<0
then begin
sellshort(1,0,marketr);
end
