同样的程序多单可以显示开空、平空信号，为什么多单就不能显示开多、平多信号？我只知道是全局变量的问题，就是不知道同样的写法空单没问题，为什么多单就出了问题了呢？不知道问题出在哪里？

上面的就是多头代码，下面的是空头代码（空头没问题，但多头就出了问题，不知为什么？）

M2:EMA(CLOSE,80);

if m1<m2 and ((j>dd AND REF(J,1)<=dd and diff<0) or (j<d AND REF(J,1)>ref(d,1) and diff>0)) and tk  and pkzy=0 and holding=0 then BEGIN
BUYSHORT(1,ss,MARKET);
end

if m1>m2 and ref(m1,1)<ref(m2,1) and  C-AVGENTERPRICE>=zs*MINDIFF  then BEGIN
SELLSHORT(1,holding,MARKET);
end

 

IF AVGENTERPRICE-C>n*MINDIFF THEN BEGIN
SELLshort(1,ss,MARKET);
pkzy:=1;
END

当前持仓:HOLDING,COLORGRAY,LINETHICK0;

 if  holding ＜0 and tg then begin
 sellshort(1,holding,MARKET);
 end

if tg then BEGIN
pkzy:=0;
end

不管日盘、夜盘，就是多单不能出信号，空单可以出信号。
