IG Trading platform:
All open positions will appear in the ‘positions’ tab on the left hand side of the platform. To close the deal click on the appropriate ‘close’ button on the same row. You will then need to confirm by clicking the highlighted ‘close’ button again.
If you have ‘1-click dealing’ enabled the ‘close’ button will automatically be green and only require one click.
Click on the position from the ‘open positions’ panel. Then click either ‘sell’ or ‘buy’, depending on the direction of the trade, to close the position. For example, if it’s a ‘buy’ trade, you would click ‘sell’ to close.
