If I put in a bid for 100 shares at 70 cents and thousands line up behind me, what if i wanted to reduce those bids to 50? As of now, the only way is to cancel all, then put in 50 bids and be sent to the back of the line. there should be a way to cancel some but not all my bids and keep my place in line.
By putting in several small bets, I wont be able to get out in time if the market crashes due to the slow site and too many clicks involved.
You can just put in several small bids instead of one big bid.
