Open the Positions tab in cTrader.
Find the position you want to manage from your list of open trades.
Choose the Close option if you want to close the full position, or adjust the amount if you want to close only part of the trade.
Review the action carefully to make sure you are closing the correct volume.
Confirm the action to complete the close or partial close.
Once confirmed, cTrader will update your open positions accordingly. If needed, cTrader also supports bulk-close actions for managing multiple positions at the same time, which can be useful when you want to exit several trades more quickly.
