Regardless of whether a stock is on a major exchange or the otcs, the patterns are still the same. Obviously there are other things that happen a lot in otc land, surprise dilution, crap financing, etc but supply and demand are still readable and most real traders wont touch a stock with a bad chart. Its all a matter of pattern recognition. Imo most people I read on these boards could have prevented a lot of bad buys had they looked at the charts and saw that they were buying into down trends.
