Might want to take a look around... some of these brokers have some pretty stinky rules that they take advantage of... case in point....had a sub-penny in Questrade a couple months ago...they would only allow trades to equal the 20-day moving average....even thought the volume had increased to 20+ mil per day - up to 50 mil, and the 20-day average was 20+ mil at this point, their risk-management would only allow less than 1 mil volume per trade and even at 9.95 per trade it still cost me 5% just to sell.....these guys are shady just like everything else in the pinks......for now I'm lucky enough to have a second broker....RBC (in Canada) that reduced their fees from 29.95 to 9.95 flat rate, plus no volume limits on low liquid stocks, and allow you to trade non-DTC stocks as well (something Questrade does not allow (hence they are locked in your account worthless, even if there's a bid)).
Definitely suggest taking a look around first.
Cheers,
Nate
