depending on the interest many stocks that trade otcbb are available with a direct access platform through ISLD ARCA ect..like wcom and km to name a few...however, i woudl never use a DA platform for that unless you were looking to scalp a few subpennies quickly...say you buy 10000 shares of a 10 cent stock on arca....thats going cost you 40.00 to 50.00 just to enter the trade on arca, not to mention your firm's commission. of about the same.....You 'd be better off finding a firm wiht a MAX rate or flat rate on all transactions like BROWN and Scottrade ect..
