If the feature is currently enabled and you would like to remove it, you are able to do so by following the above steps.

When you have enabled One Click Trading, this will appear on your chart. 

You are able to add the number of lots you would like to buy or sell in the highlighted area.

By clicking on BUY or SELL, your trade will be immediately executed.
