ma4:stkindi('',ma(close,42),0,11);

sell(c<ma4 and holding>0,0,market);
buyshort(close<ma4 and holding=0,1,market);

sellshort(c>ma4 and holding<0,0,market);
buy(close>ma4 and holding=0,1,market);

以上程序问题出在哪？

平仓数量上怎么会是 0 .

ma4:stkindi('','ma.MA1',0,11);//加上一对单引号，然后在MA公式里面把MA1的参数改成42

sell(c<ma4 and holding>0,0,market);
buyshort(close<ma4 and holding=0,1,market);

sellshort(c>ma4 and holding<0,0,market);
buy(close>ma4 and holding=0,1,market);
