As to the MA_Period, I have found the following.
https://www.linnsoft.com/techind/evw...moving-average
eVWMA = [(N - v) * eVWMA.1 + v*p] / N where... p = price v = volume of bar N = volume "period". This period can either be specified (as a constant value) or computed as a multiple of the recent average volume.
Let us try to ubdertsand.
1. P is price, understandable, no comments;
2. V - volume of a bar - it seems to undersandable as well;
3. N is volume "period".
This period can either be specified (as a constant value) or computed as a multiple of the recent average volume.
Here we have a problem. In the original formula N is the number of shares floating. However we have no shares in FOREX. That is why we have difficulties up on this issue.
So, look at the picture at the abowe link. You can see eVWMA(DELL, 10000). I suppose, N = constant and is qual to be 10000. That is the answer why we should take MA-period to be a high number.
Let us discuss.
Best,
D.P.
