尋求幫助，客服來(lái)幫我看看　[金字塔]

GLOBALVARIABLE:YL:=0; ------ 設(shè)全局變量
IF HOLDING>O THEN BEGIN----如果持有多單的時(shí)候
YL:=IF00C-ENTERPRICE;------定義盈虧，當(dāng)前價(jià)個(gè)減去成本價(jià)
sell((YL>5 OR ENDTIME),shou,limitr,d2);----有5點(diǎn)的盈利，就跑了
sell(YL<-2.8,SHOU,MARKETR,C-5*MINDIFF);----虧損2.8就止損了
END
IF HOLDING<0 THEN BEGIN------下面是持有空單的時(shí)候，同理
YL:=ENTERPRICE-IF00C;
sellshort((YL>5 OR ENDTIME),shou,limitr,d1);
sellshort(YL<-2.8,SHOU,MARKETR,C+5*MINDIFF);
END

請(qǐng)問(wèn)，高手們，我這樣寫有問(wèn)題嗎，為啥達(dá)到條件，不會(huì)出場(chǎng)？

圖表全局變量是variable,你用超全局變量是有特殊用處還是不知道用處看見(jiàn)是全局變量就用了？

如果用后臺(tái)交易呢，這個(gè)全局變量是用哪個(gè)？

GLOBALVARIABLE:YL:=0;
IF THOLDING>O THEN BEGIN
YL:=C-TENTERPRICE;
Tsell((YL>1OR ENDTIME),shou,LMT,d2);
Tsell(YL<-2.8,SHOU,MKT,C-5*MINDIFF);
END
IF THOLDING<0 THEN BEGIN
YL:=TENTERPRICE-C;
Tsellshort((YL>1OR ENDTIME),shou,LMT,d1);
Tsellshort(YL<-2.8,SHOU,MKT,C+5*MINDIFF);
END

我把改成后臺(tái)，咋還是不會(huì)平倉(cāng)呀，我先顯示出盈利數(shù)值，去掉等號(hào)，提示重復(fù)定義YL
