I think it's useful somewhat but, not all that reliable LOL if that makes any sense. I don't use it when i'm day/swingtrading otc stocks, I just watch a live 4 min chart with time and sales(i use Medved Quotetracker it's free) so i can see the buys and sells. What i do is pretty simple, when a otc stock jumps way outside the upper bb on the daily. and everybody starts selling I sell and take my profit. Hopefully. It doesn't matter how great the news or mo mo or whatever. When a stock price jumps way outside the upper bb on the daily chart. it ALWAYS comes back inside the bbs.
cap.
