  1. You park a buy limit order @ best bid + 0.01 for 100 shares. This is all going on the same exchange

    So it reads (1) 20.25

    ... then someone else joins you and it reads
    (2) 20.25.

    ... then you decide to bid 100 more shares and it reads
    (3) 20.25.

    A sell market order comes for 200 shares.

    How many shares are you filled?
  2. balda


  3. Adding QTY is basically the same as cancel/replace, at least with what I trade.

    I agree with balda.
