求老师帮忙

//为什么我的后台止赢不好用，是哪里写错了？

//如果持仓盈利大于50点则开始移动止赢
持仓:=holding;
持仓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

后台不要用图表全局变量variable

后台的全局变量是用extgbdataset或者GLOBALVARIABLE
GLOBALVARIABLE用法和variable一样，extgbdataset用法看函数说明，比GLOBALVARIABLE复杂一点

好的，我具体研究一下

谢谢!
