In trading, there are often times that you were in a hurry and accidentally opened up on emotions in the wrong direction on the news or you opened for a purchase, but the price is on sale and your strategy gives signals only for sales and you need to close the order very quickly and open in the opposite side.
In order to make a reverse order, you need to select the order you need in the lower trading panel of the terminal and click on the Reverse tab
And your current order will instantly close and an order will open in the other direction of the same volume
