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);

以上程序問(wèn)題出在哪？

平倉(cāng)數(shù)量上怎么會(huì)是 0 .

ma4:stkindi('','ma.MA1',0,11);//加上一對(duì)單引號(hào)，然后在MA公式里面把MA1的參數(shù)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);
