我的思路是5日均线以下，出现大阳线，收盘价不超过5日均线，就做空，第二日收盘平仓
5日均线以上，出现大阴级，收盘价不超过5日均线，就做多，第二天收盘平仓
但代码好像有问题，版主能不能帮忙看看？
input fudu(1.3,1,9,0.1)
input tian(5)
ma5:ma(close,tian);
kd:=(-((close-open))/ref(close,1)>fudu/100) and (close>ma(close,tian));
pd:=holding>0 and barslast(holding=0)=1;
kk:=(close-open)/ref(close,1)>fudu/100 and (close<ma(close,tian));
pk:= holding<0 and barslast(holding=0)=1;
开多:BUY(KD AND HOLDING=0,1,THISCLOSE);
平多:SELL(PD,1,THISCLOSE);
平空:SELLSHORT(PK,1,THISCLOSE);
开空:BUYSHORT(KK AND HOLDING=0,1,THISCLOSE);
