if ( RaiderOBV(Close, Period)[0] > SMA(Close, Period)[0]) Just glancing at the code, inside RaiderOBV calling this is not a good idea. See Recursion

so calling the indicator inside of itself - was that the real reason of the NT-Crash / forced close now ?

Thanks, Jon. They definitely take getting used to but I'm now at the point where I can't even look at normal candles anymore. Anyway, these tend to (help) keep me out of trouble.

Happy trading,
Dave

MAX!!

I guess so. I'm now calling the regular OBV and using OBV as the SMA input and all is well with the world.

Almost forgot. In case any of you are interested in the final product, it's now in the download section for 6.5: View Download Details - Big Mike's Day Trading Forum
