Tomasz,
thanks for the example. Why did you choose to multiply the average volume by
5? Was this an arbitrary number? The original post was doing a 5 day
weighted MA but this is a 20 day weighted ma, correct? I can see that we
need to keep the 2nd part of the expression less than zero but I am still a
bit lost as to what the second number is trying to show? Sorry for being so
dense, I know you have tried to explain this before but it just wont sink in
:((

Alan,
It depends on what kind of volume-weighting you prefer.
If simple weighting - that is OK.
If exponential-like volume weigted you may try this:
Period = 20;
N = 5 * MA( Volume, Period );
VWMA = AMA( Close, Volume/N );
(this average implements dynamic (adaptive) smoothing
depending on the ratio of current volume to average volume
of period last days )
Best regards,
