  • Fill or Kill Buy Order

    Order Type In Depth - Fill or Kill Buy Order

    Step 1 – Enter a Fill or Kill Buy Order

    At 10:00 AM Tuesday, you want to place an order to 1000 shares of XYZ stock. You want the entire order to fill right away, otherwise you don't want it. Create the buy order, select an order type from the Type field (in this example, we've chosen a limit order), and select FOK as the time in force. If the entire order does not fill immediately once it is accepted by the market, the entire order is canceled.

    Assumptions
    Action BUY
    Qty 1000
    Order Type LMT
    Market Price 13.50
    Limit Price 13.50
    Time in Force FOK

    Step 2 – Buy Order for 1000 Shares Transmitted

    You've transmitted your limit order with the time in force set to Fill or Kill. If the entire order does not fill immediately once it is accepted by the market, the entire order will be canceled.

    Assumptions
    Action BUY
    Qty 1000
    Order Type LMT
    Market Price 13.50
    Limit Price 13.50

    Step 3 – Order is Filled Immediately

    Your limit price and the market price of XYZ are the same, 13.50, when you transmit the order. Your entire order is immediately filled.

    Assumptions
    Action BUY
    Qty 1000
    Order Type LMT
    Market Price 13.50
    Limit Price 13.50

    Alternate Scenario – Market Price Moves Away from Limit Price, Order Cannot Be Filled Immediately

    In this alternate scenario, the market price of XYZ rises to 13.51, away from your limit price of 13.50. Your entire order cannot be immediately filled so it is canceled.

    Assumptions
    Action BUY
    Qty 1000
    Order Type LMT
    Market Price 13.51
    Limit Price 13.50
