主题：简单的后台模型，麻烦帮忙修改

我按你的意思改了一下，你看看对不？

ss:=1; //手数
EXTGBDATASET('T1_POSITION',0);
//0表示没有仓位，1表示持有多头， -1表示持有空头
EXTGBDATASET('T1_holding',0);
//0表示没有仓位，>0表示持有多头， <0表示持有空头

MAA:MA(C,7);
BPK:=CROSS(C,MAA);
SPK:=CROSS(MAA ,C);
//没有持仓状态
if bpk and EXTGBDATA('T1_POSITION')=0  and EXTGBDATA('T1_holding')=0 then begin

      tbuy(1,ss,mkt);
      EXTGBDATASET('T1_POSITION',1);
      EXTGBDATASET('T1_holding',ss);
     
end

if spk and EXTGBDATA('T1_POSITION')=0 and EXTGBDATA('T1_holding')=0 then begin

       tbuyshort(1,ss,mkt);
       EXTGBDATASET('T1_POSITION',-1);
       EXTGBDATASET('T1_holding',-ss);
end
//持有仓位状态
   //持空头
IF BPK AND EXTGBDATA('T1_POSITION')=-1    AND TENTERBARS>=1 THEN BEGIN

       tsellshort(EXTGBDATA('T1_holding')<0,ss,mkt);
       TBUY(1,ss,MKT);
       EXTGBDATASET('T1_POSITION',1);
       EXTGBDATASET('T1_holding',ss);
      
END
    //持多头
IF SPK AND EXTGBDATA('T1_POSITION')=1  AND TENTERBARS>=1  THEN BEGIN

        tsell(EXTGBDATA('T1_holding')>0,ss,mkt);
        TBUYSHORT(1,ss,MKT);
        EXTGBDATASET('T1_POSITION',-1);
        EXTGBDATASET('T1_holding',-ss);
       
END

if  time>=151300 then begin

             tsell(EXTGBDATA('T1_holding')>0,ss,mkt);
             tsellshort(EXTGBDATA('T1_holding')>0,ss,mkt);
             EXTGBDATASET('T1_POSITION',0);
             EXTGBDATASET('T1_holding',0);
                     
end

Position:=EXTGBDATA('T1_POSITION');
T1Holding:=EXTGBDATA('T1_holding');

DEBUGFILE('D:\Debug\803555.TXT','Position=%.0f' ,Position) ;
