At DEGIRO it is possible to make use of a combination order.
If you make use of the Desktop version, you can move your cursor to the 'Place an Order' button that is located at the top right. Within this button you will see an arrow, if you move the cursor over this arrow, a dropdown menu will appear with the text 'Combination Order'. If you select this, you can place a combination order.
If you are trading via the mobile app, you can click on the blue circle with a white + in it to place an order. Then you can click on 'Other orders' under the search bar, after which you can select 'Combination order'.
Please be aware that by minimizing your screen on Desktop, the platform will change to the mobile app version and thus the location of the ‘Combination Order’.
