Your high volume requirement probably made all the difference.
I used EquityFeed for my penny stock scans, as it scans in real time, but unfortunately, it can be quite buggy.
I mainly focused on subpenny stocks at the beginning stages of a breakout, or ones that were beaten down and looked like they might pop. I even created some sudden volume scans to try to find frontloading.
I'm guessing my problem was that I was attempting to create a predictive scan using relatively low dollar volume movements. I got way too many false positives.
I probably would have been more successful if I moved to a better subset of penny stocks, but the trade activity and dollar volume for Nasdaq/AMEX/NYSE stocks is just so much more attractive.
I'll have to read up on Hurst this weekend. Thanks for the info.
