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

請問，高手們，我這樣寫有問題嗎，為啥達(dá)到條件，不會(huì)出場？

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是全局變量就用了？

如果用后臺交易呢，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，咋還是不會(huì)平倉呀，我先顯示出盈利數(shù)值，去掉等號，提示重復(fù)定義YL
