For orders using the All or None (AON) attribute, IB will typically route to the native exchange, or hold the order if the AON order type is not supported by the primary exchange. When held, IB will attempt to simulate the order as follows:

  • For US stock orders: The NBBO must qualify limit price AND the NBBO size must be equal to (or greater than) the order size + 1000 shares.
  • For US options orders: The NBBO must qualify limit price AND the NBBO size must be equal to (or greater than) the order size + 10 contracts.

For example, an AON order to buy 1500 shares of ABC at $10.00/share will be held until the NBO qualifies (is less than or equal to $10.00) and the NBO size is equal to or greater than 2500 shares.

The order will remain active until it either executes or is canceled. The AON attribute can be used in conjunction with the basic order types and all times in force.

Example


  • All-or-None Buy Order

    Order Type In Depth - All-or-None Buy Order

    Step 1 – Enter a Limit Order and Apply the All-or-None Order Attribute

    You want to place an order to buy 10 Jan11 140 calls of XYZ, but you do not want the order to execute unless the entire order quantity is available. Before you place the order, make sure the All or None column is displayed on the trading screen. Click the check box in the All or None field to tag the order as All-or-None. If the entire quantity becomes available at the specified price or better, the order will be filled. Otherwise, it continues to work until it is canceled.

    Assumptions
    Action BUY
    Qty 10
    Order Type LMT
    Limit Price 3.95
    Order Attribute All or None
    Market Price 4.00
     
  • All-or-None Buy Order

    Order Type In Depth - All-or-None Buy Order

    Step 2 – Order for 10 Options Contracts Transmitted

    You've transmitted your order for 10 Jan11 140 calls of XYZ. At this point, the contracts are nether available at your limit price nor for the entire quantity. If the entire quantity becomes available at your Limit Price or better, the order will be filled. Otherwise, it continues to work until it is canceled.

    Assumptions
    Action BUY
    Qty 10
    Order Type LMT
    Limit Price 3.95
    Order Attribute All or None
    Market Price 4.00
     
  • All-or-None Buy Order

    Order Type In Depth - All-or-None Buy Order

    Step 3 – Market Price Falls, Partial Quantity is Available

    The price of the XYZ options contracts falls to 3.95, which is your Limit Price. However, only four contracts are available at that price. Because this is an All or None order, your order cannot be filled until the entire quantity becomes available at your desired price.

    Assumptions
    Action BUY
    Qty 10
    Order Type LMT
    Limit Price 3.95
    Order Attribute All or None
    Market Price 3.95
     
  • All-or-None Buy Order

    Order Type In Depth - All-or-None Buy Order

    Step 4 – Entire Quantity is Now Available

    Finally, the entire quantity of 10 options contracts becomes available at your limit price, so the order is filled.

    Assumptions
    Action BUY
    Qty 10
    Order Type LMT
    Limit Price 3.95
    Order Attribute All or None
    Market Price 3.95
