Attach an Auto Trailing Stop Order
You can attach a trailing stop order to a limit order. The attached trailing stop order is automatically activated when the limit order is filled.
To attach an auto trailing stop
Right-click on a limit order and select Attach, then select Auto Trailing Stop.
To modify the trailing amount, change the value in the Aux. Price field.
To change the default trailing amount used to calculate the stop election price, use the Order > Order Defaults page of Global Configuration.
When the limit order executes, the trailing stop order is submitted. The stop election price will be calculated using the (parent order limit price + trailing amount) for Buy orders, and the (parent order limit price - trailing amount) for Sell orders.
The relationship between the parent and attached order can be seen in the Trailing Key field. Related orders are assigned the same trailing key.
