A similar question came into Support. We had to make a slight change to make it work consistently:
n:=Input("Enter the number of shares:",100000000,100000000000,100000000);
eVWMA:=((n-V)*PREV+(V*C))/n;
eVWMA
<<
This works even less on EOD data ... one has to enter a value not less than 100,000,000 ... considering that n excludes shares held by institutional investers this doesn't let the formula do what it is supposed to, i.e. enter a number of shares that is significantly smaller than the total (C.F. suggests 1%).
Please also note that Reuters scales EOD volumes by 100.
Care to try again Equis :-) ?

In the June issue of TASC is an article by Christian Fries on the development of a "Elastic Moving Average", a volume sensitive moving average. The basic formula to make the indicator is:
n:=Input("Enter the number of shares: ",1,1000000,1);
eVWMA:=((n-V)*PREV+(V*C))/n;
eVWMA;
It has interesting possibilities and provides good opportunities to play with, however I have two problems with it:
1) applying it to the QQQ I get an "Overflow in MUL() function". I think this is due to the high volumes of the QQQ. Any ideas how to fix this?
2) the QQQ has a rather wide range of volumes since its inception and the eVWMA changes character rather drastically over a period of several years for this equity. With a number of shares of 1000000 it starts off rather smooth but in the end it is hardly distinguishable from the price. As is, its usefulness appears short term...
I would like it to maintain its filtering characteristic more constant over time with EOD prices, i.e. its usefulness as compared to the price, by scaling the "no. Shares" input with a volume derived factor (perhaps MA?). Any ideas on this?
Best regards,
Herman.
