How do we calculate your cancel order limit if you place a window order with both buys and sells?

How do we calculate your cancel order limit if you place a window order with buys only?

How do we calculate your cancel order limit if you place a window order with sells only?

Here’s how we calculate your cancel order limit if you place a window order with sells only. The example assumes that you are placing an order at 11:00 a.m. ET to sell $500 of security A and $500 of security B, and that you have set your cancel order limit at 5%. The order will be executed in the afternoon window.

  1. We add up the values of all your sells.

    Your order when you placed it at 11:00 a.m. ET:

      Price-Per-Share Total Shares Total Value
    Sell security A $100 5 $500
    Sell security B $50 10 $500
  2. We calculate the dollar value of your limit against your total sells.

    Your limit is 5%.
    Your sells total $1000.
    5% of $1000 = $50

    Your order when you placed it at 11:00 a.m. ET:

      Price-Per-Share Total Shares Total Value
    Sell security A $100 5 $500
    Sell security B $50 10 $500
  3. When the window closes, we add up how much your sells have gone down in value since you placed the order.

    (The cancel order limit does not apply when your sells gain value.)

    Your order when window closes:

    Price-Per-Share at: 11:00 a.m. ET 2:45 p.m. ET Shares Total Move
    Sell security A $100 $92 5 $40
    Sell security B $50 $49 10 $10
    Total $50
  4. If the total meets or exceeds the dollar value of your limit, we will cancel your order.

    The order is cancelled because the total price has moved down by $50, your dollar limit.

    Price-Per-Share at: 11:00 a.m. ET 2:45 p.m. ET Shares Total Move
    Sell security A $100 $92 5 $40
    Sell security B $50 $49 10 $10
    Total $50
  5. Now picture another scenario, using the same assumptions as in the first example.

    What happens if, between the time you place the order and the time the window closes, the securities you are selling go up in value?

    Price-Per-Share at: 11:00 a.m. ET 2:45 p.m. ET Shares Total Move
    Sell security A $100 $110 5 $50
    Sell security B $50 $52 10 $20
    Total $70
