By default your trading is open to quickly place and remove orders but should you decide to take a break and prevent any miss clicks there is a platform wide lock on trading by navigating to the upper right of your toolbar and finding the Lock icon

Once pressed the icon will go from white to Red and a message should appear below it to confirm

Hovering back over the red icon will highlight the red Lock icon and will display you’ll be able to unlock when pressed

Clicking into the red Lock icon will unlock across your platform the ability to once more place trades confirmed by a message below the icon to confirm

Navigating to the upper right of your DOM and Charts we have similar functionality though this will only lock trading from that specific DOM or Chart
