if holding=0 and time<144000 then //开多 tbuy(KAIDUO,200,STPLMT,close-30,close-50+20); if holding=0 and time< 144000 then //开空 tbuyshort(KAIKONG,200,STPLMT,close+30,close+50); if holding>0 then //平多 tsell(PINGDUO,holding,lmt,close); if time=145700 then tsell(time=145700,holding,lmt,close); if holding<0 then //平空 tsellshort(PINGKONG,holding,lmt,close); tsellshort(time=145700,holding,lmt,close); 把buy等相应改成tbuy,怎么测试就没有成交,错在哪里?
