The Conditional order type does not support Stop or Stop Limit Orders. It is possible to select other order types such as Limit or Market in the conditional order.
If you wish to enter a conditional order on a position, right click on the position in your portfolio and select Trade followed by Order Ticket. Configure the order as desired (please note, all order types may not be available). To attach the condition, click on the Conditional tab at the top and configure as desired.
It is also possible to create a stop loss order on a particular instrument based on an Alert for price movement. To set up Alerts in the Trader Workstation, right click on the symbol you wish to set the Alert for and left click on the Alert (bell) icon in the right click menu. Click the Advanced Settings button and choose Price as the Condition type and click Next. Configure the condition and enter the details as desired and click Finish once complete. Once the Condition description is populated, under the Actions section you can select Orders and click Add. You can create your Order on the Order line as desired. Finally, go down to the Duration section and set your duration preferences. Once complete, click Activate at the bottom of the window.
Please note, you can test a new order type or strategy in your Paper Trading Account first. When logging in to your trading platform, choose Paper Trading as the Mode to access it.
