Interesting results:
begvol = TimeNum() == 093500;
endvol = TimeNum() == 114500;
CountWhile = Flip(begvol,endvol);
Cumvol = IIf(CountWhile,Sum(V,BarsSince(begvol)),0);
Plot(Cumvol,"cumvol",1);

Subject: [amibroker] Cumulative Volume Indicator
I am trying to create a cumulative volume indicator based upon
certain times during the day. For example, I would like to know
the premarket volume of spy from 8amEST to 092000 EST. This would
be cumulative from 8 to 9:20 and then it would go to 0 and start
over every day from 0 at 8AM EST. This is what I have so far:
Sumvol = Cum(V);
begvol = TimeNum() == 093500;
endvol = TimeNum() == 114500;
cumvol = IIf(TimeNum() >= begvol AND TimeNum()<= endvol, Sumvol,0);
When I plot this I get a blank window. Would anyone like to help me
out?
Thanks
Eric
