variable:aa=0;

if c>aa then aa:=c;

if aa>0 and c<=aa-10*mindiff  and holding=1 then sell(holding>0,1,thisclose);

if aa>0 and c<=aa-20*mindiff and holding=2 then sell(holding>0,2,thisclose);

if holding=2 then begin
 
 sell(l<=h135-10,1,LIMITR,h135-10);
 
 sell(l<=h135-20,1,LIMITR,h135-20);
 
 end

这样 表达对么

variable:aa=0,bb=0;

 加个开仓语句保证全局变量不出错

if buycond then begin

buy();

aa:=0;

bb:=0;

end

if c>aa then aa:=c;

if aa>0 and c<=aa-10*mindiff  and  holding=1 then sell(holding>0,1,thisclose);

if aa>0 and c<=aa-10*mindif and holding=2 and bb=0 then begin

sell(holding>0,1,thisclose);

bb:=1;

end

if aa>0 and c<=aa-20*mindiff  and bb=1 then sell(holding>0,1,thisclose);
