主题：信号出现不闪动.

老师好!如下模型信号出现有闪动.不稳定.请给更改为不闪动.信号出现不消失.我要用固定轮模式下单交易.

Z1:=ref(LLV(L,27),1);
Z2:=ref(HHV(H,27),1);
VAR21:=(C-Z1)/(Z2-Z1)*10000;
VAR22:=REVERSE(VAR21);
VAR23:=SMA(VAR21,3,1);
K:=SMA(VAR23,3,1);
D:=SMA(K,3,1);

if k-d>0 then begin
   sellshort(1,0,limitr,OPEN+0*mindiff);
   buy(holding=0,1,limitr,OPEN+0*mindiff);
end
 
if k-d<0 then begin
   sell(1,0,limitr,OPEN-0*mindiff);
   buyshort(holding=0,1,limitr,OPEN-0*mindiff);
end
