[amibroker] Re: Cum of Sum young guy

["Julian" <juliangoodsell@xxxxxxxxxxxx>]

Thanks Tomasz,
that worked with a bit of jigging. Subtracting the volume from the
start of the day leaves you with no volume on that bar so have to
subtract from end of yesterday.
Is there a better way to get last bar of day without forward looking?

d = Day();
newDay = d != Ref(d, -1);
eod = Ref(newDay, 1);       // Last bar of day
CumVolume = Cum(V);
Vw = Ref(ValueWhen(eod, CumVolume), -1);  // Subtract volume from eod
Vw = Nz(Vw, 0);  // Zeros for first day
intradayCumVolume = CumVolume - Vw;
