Harold/Sam....You can use logs instead of dividing by the mov to normalize the calculation. WOW will handle logs for a number of applications

I agree fully that normalizing is essential to remove price magnitude effects.

Also, BBs don't have to be just 1 StD from the average. They can be anything (within reason). 1 StD BB will enclose about 68% of the data values, 2 StD will enclose about 95.5%, 3 StD will enclose about 99.7%. WOW will take fractional values of the StD, e.g., 1.5.

Hope this helps a little.

Bill.
