IB's Discretionary orders: adding or removing liquidity?

Discussion in 'Order Execution' started by isaac000, Dec 7, 2006.

  1. Since adding or removing liquidity makes big difference if using IB's unbundled commission structure, I would like to know the following three order types are considered adding or removing liquidity:

    1. Discretionary Limit Orders (say you enter a buy limit order with limit price $10 and discretionary amount $0.90. someone offers $10.90 and your order is excuted at $10.90.)

    2. Same Discretionary Limit Orders as above, but with a small display size (example: showing 100 shares for a 1000 order).

    3. Hidden Orders
