The pinks are not so bad, but the grey sheet ones have no bid/ask and no time or price precedence. Trading is totally blind. So you could put a sell which would correspond to the the Venture exchange bid in and it might sell on 1 minute, 1 hour, 1 day or never, even below the bid it could just sit and sit. Unless there is lots of trading in the issue it is really crappy, whereas with the venture exchange, click, done.
