Attach Automatic Stop Order
You can attach an opposite-side stop order to any order using the Attach Auto Stop command. TWS creates the opposite side stop, and calculates the stop election price using the limit price of the parent order plus/minus stop offset amount. The stop price is displayed in the Stop Price field if you have made it visible. Otherwise it is displayed in the Aux Price field. The attached stop order is automatically activated when the parent order to which it is attached executes.
To attach an auto stop order
Right-click on an order line and select Attach, then select Auto Stop.
To modify the stop election price, change the value in the Aux. Price field or the Stop Price field if that is visible.
To change the default stop offset amount used to calculate the stop election price, use the Order > Order Defaults page of Global Configuration.
