[amibroker] real time scanning challenges

[murthysuresh]

Hello
I am doing realtime scanning and have the backfill checkbox turned on. 
however sometimes, i find that i get results that are not today's data 
especially in the mornign sessions. so i actually updated the formulaa 
to force return of today's results only. is there a better way? i use 
dtniq as realtime feed

relativevolume=(((LastValue(TimeNum())-93000.00)/63000)) * LastValue
(V,20);
Luckybreakdown=Close>15 AND Close<Ref(LLV(L,20),-1) AND V>1.5*  
(relativevolume) AND LastValue(DateNum() )==GetRTData("UpdateDate");
Luckybreakout=Close<50 AND Close>Ref(HHV(H,20),-1) AND V>1.5*  
(relativevolume) AND LastValue(DateNum() )==GetRTData("UpdateDate");
