主题：3分钟重复成交再次出现,有源码

今日3分钟线再次出现重复成交(10:51:00及10：52：59)，请教啥原因，源码如下：

kk:=(ref(h,1)>=ref(upper2,1) or ref(h,2)>=ref(upper2,2) or ref(h,3)>=ref(upper2,3)) and ref(c,1)<ref(o,1);
kk2:=REF(aa,1)<5 and (ref(h,1)>=ref(upper2,1) or ref(h,2)>=ref(upper2,2)) and ref(c,1)<ref(o,1) and ref(l>lower2,1);

if not(time=151500) then begin
if kk and kuandu and holding>0 then begin
sell(1,ss,limitr,o-hd20);
end
if time>092700 and kk2 and holding=0 then begin
buyshort(1,ss,limitr,o);
end
end
