Questions about the above. I wish to buy 200 shares of XYZ stock. Say I put in my price 1/2 way between the bid/ask. If I do a "all or none" I move to the back of the line behind all the people who have odd lots (or 100 share lots) moving in front of me. If I don't do a "all or none", I could end up with an odd lot(s) for the day (having to pay full price for the trade). I am talking about Fidelity and Schwab. How can I make sure I don't end up with an odd lot or end up with 2 separate 100 share trades and the fees that go with them??
