請(qǐng)問高手:我的介入價(jià)止損代碼對(duì)不對(duì),是不是這樣寫　[金字塔]

//建立多頭的進(jìn)場(chǎng)條件
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;//持倉(cāng)價(jià)位
 SELL(HOLDING>0,HOLDING,Stopr,Price*0.9977);//止損
 end
//Price:=AVGENTERPRICE;//持倉(cāng)價(jià)位
//畫出多頭的止損線
partline(holding>0,Price*0.9977,colorred);

//開空條件
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;//持倉(cāng)價(jià)位
 sellshort(holding > 0, 0, Stopr,Price*1.0027);
 end

//畫出空頭的止損線
partline(holding<0, Price*1.0027, colorgreen);

//收盤前5分鐘平倉(cāng)
if time >= 151200 then
 begin
 sell(holding > 0, 0, limitr, open);
 sellshort(holding < 0, 0, limitr, open);
 end
