You can close out of a trade on Trading Station mobile in multiple ways, whether one at a time, or all at once.
From the Open Positions tab, you can monitor the performance of your open trades. The trade size, the profit or loss in pips, and the profit or loss in terms of currency are all listed here.
When you are ready to close a trade, settling the profit or loss into your balance, tap on the Trade, and then select Close. After confirming the order settings, tap Close again. If you have multiple trades open in the same instrument, you can close them all at once from the Summary tab. As before, select the instrument you wish to close, and then tap Close All.
You can review your closed trades from the Closed Positions tab.
