It really depends how you are set up. If I put an order for 1000 in I only pay 9.95/trade and that trade is 1000 shares. If they only sell 100 then 900 the next day i still pay the 9.95 once. If i canceled the trade after 100 got sold then the next day tried to sell the 900 that would be 2 trades and would have to pay for 2 trades. So it depends on how you are set up. I always move in big lots anyways. Well big for me.. :) TTY
