求老師幫忙

//為什么我的后臺止贏不好用，是哪里寫錯了？

//如果持倉盈利大于50點則開始移動止贏
持倉:=holding;
持倉1:=THOLDING2;
VARIABLE:biaoji=0;
VARIABLE:zuigao=0;
VARIABLE:zuidi=0;
if h-tenterprice>50 and tbuyholding(0)>0 and biaoji=0 then begin
     zuigao:=HIGH;
     biaoji:=1;
end
if HIGH>zuigao and tbuyholding(0)>0 then zuigoa:=HIGH;
if LOW<zuigao-1 and tbuyholding(0)>0 then begin
 tsell(1,0,mkt);
 biaoji:=0;
end
if tenterprice-l>50 and TSELLHOLDING(0)>0 and biaoji=0 then begin
 zuidi:=LOW;
 biaoji:=1;
     end
 if LOW<zuidi and TSELLHOLDING(0)>0 then zhuidi:=LOW;
 if HIGH>zuidi-1 and tbuyholding(0)>0 then begin
 tsellshort(1,0,mkt);
 biaoji=0;
 end

后臺不要用圖表全局變量variable

后臺的全局變量是用extgbdataset或者GLOBALVARIABLE
GLOBALVARIABLE用法和variable一樣，extgbdataset用法看函數說明，比GLOBALVARIABLE復雜一點

好的，我具體研究一下

謝謝!
