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
 
Thanks,

  TASC)
  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.
