还是老问题：平多盈利执行不及时，盈利全部吃光：程序源码

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

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

//空头为例
  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线是阴线，怎么会出信号的？

那在这里一次性理清思路，你要的开仓后3根k线之外还是之内满足条件后平仓？

开仓后3根k线之外是原来的代码

开仓后3根k线之内是下面的代码

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

//空头为例
  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
