Theo,
Ron answered your question. I answered another question which is a problem
if your period is to low. You can get a divide by 0 problem if their is no
volume
movement over a short time period. My response below fixes that problem.

====================================================
Theo,
This is a common problem with the StocRSI as well as the StocOBV with small
periods.. I haven't tried this, but try replacing the line below with the
line
underneath. It will introduce a less then 1% error but should get rid of
the
problem. let me know how it works out, if it doesn't work I will work on a
solution.
Bill
replace 100-(100/(1+(UE/DE)));
with
100-(100/(1+(UE/(DE+.000001))));
