平多信號還是沒有及時執(zhí)行

還是老問題：平多盈利執(zhí)行不及時，盈利全部吃光：程序源碼

//開多
IF ( stopprice)<l THEN
BEGIN
SELLSHORT( HOLDING<0,HOLDING,market); //平空操作
BUY( HOLDING=0,1，market);//開多操作 
maxprofit:=0;
END
//平倉
SELL((stopprice)>h and  HOLDING>0,HOLDING,market);//平多
BUYSHORT((stopprice)>h and HOLDING=0,1,market); //開空操作

if enterbars>=3 then begin
     if c>o and holding>0 then sell(1,holding,market);
     if c<o  and type(1)= 2 then buy(holding>=0,1,market);
  end

//空頭為例
  if enterbars>=3 then begin
     if c>o and holding<0 then sellshort(1,holding,market);
     if c<o and type(1)=4 then buyshort(holding<=0,1,market);
  end

那根k線是陰線，怎么會出信號的？
