OCO
An OCO (One Cancels Other or Order Cancels Order) consists of a:
- Buy limit order below the market and a buy stop order above the market, or
- Sell limit order above the market and a sell stop order below the market.
When one order is filled, the other is automatically canceled. If one order is partially filled, the remaining volume on the other order is reduced accordingly.
How to Enter an OCO
- Left-click on the OCO option — the color will turn orange to indicate it is active.
- Two blank boxes will appear under the order types:
- One labeled L for limit
- One labeled S for stop
Submitting the OCO Order
- Clicking in the Bid column will populate the appropriate box with your limit or stop price, depending on the OCO setup.
- Click the Submit button to send the selected limit and stop OCO order.
- Click the TKT button to bring up the New OCO Revision window, allowing you to adjust the OCO before submitting.
Managing OCO Orders
- If one side of the OCO is filled, the other side is canceled automatically.
- To cancel both orders manually, simply click on one of them — both will be canceled together.
Verifying OCO Orders
You can confirm and monitor your OCO orders in the All or Working tab of your Order Book.
