请问高手:我的介入价止损代码对不对,是不是这样写　[金字塔]

//建立多头的进场条件
long :=VBuy and time>=092700 and time<=150000;

if long then
 begin
 sellshort(holding < 0, 0, limitr, open);
 buy(holding = 0, 1, limitr, open);
 Price:=AVGENTERPRICE;//持仓价位
 SELL(HOLDING>0,HOLDING,Stopr,Price*0.9977);//止损
 end
//Price:=AVGENTERPRICE;//持仓价位
//画出多头的止损线
partline(holding>0,Price*0.9977,colorred);

//开空条件
short := VSell and time >= 092700 and time <= 150000;

if short then
 begin
 sell(holding > 0, 0, limitr, open);
 buyshort(holding = 0, 1, limitr, open);
 Price:=AVGENTERPRICE;//持仓价位
 sellshort(holding > 0, 0, Stopr,Price*1.0027);
 end

//画出空头的止损线
partline(holding<0, Price*1.0027, colorgreen);

//收盘前5分钟平仓
if time >= 151200 then
 begin
 sell(holding > 0, 0, limitr, open);
 sellshort(holding < 0, 0, limitr, open);
 end
