 以上兩個開倉條件同時滿足軟件就開了兩次倉，而我只要求開一次

variable:n=0

if  vol_1>=vol_2+vol_3+vol_4 and c_1<o_1-n6   and n=0 then 
 begin
  buySHORT(1,lots,limitr,open),IGNORECHECKPRICE;
 HigherAfterEntry:=enterprice;
 LowerAfterEntry:=enterprice;

n:=1;
   end
  
if  vol_1>=avvol*3 and c_1<o_1-n7  and n=0 then 
  
  begin
  buyshort(1,lots,limitr,open);
 HigherAfterEntry:=enterprice;
 LowerAfterEntry:=enterprice;

n:=1;
   end

用全局變量來記錄下單狀態(tài)，為0時能下單，只要有任意一個交易了，變?yōu)?，后面的就不能交易
