I'm not aware that one can trade otcbb stocks after hours.I know they can be traded pre-market in the AM but not in the evening from 4-8. Correct me if I am wrong?
there is not "extended hours" (pre or after-market) trading with BB stocks...what you see in the am is line-up of bid and ask for the open and at the close the bid/ask are those posted by MM during the day that were not taken removed...but cant be acted upon.
