Yes, I should have mentioned thatplus many more reasons, but I would be typing forever. But I will add one more reason. They fill you in line no matter who (and how much money they have) is behind you. I have traded pinks and been passed over and someone got filled cheaper than I had a standing order in for. If the bid shows 20.0 and you put in an order to buy 20,000 shares, the bid changes to 40.0
If 40,000 shares are sold at that price, you are in the stock.
