Not many traders know about this feature but you can visualize your closed trades directly on your charts. For that, open your terminal (hotkey CTRL + T), go to account history and then drag and drop a trade onto your chart.
MetaTrader will then draw the entry and the exit with 2 arrows and connect the distance with a dotted line. MetaTrader also visualizes the stop loss order and take profit orders with small red and blue lines.
This feature is especially helpful if you want to save screenshots of your older trades. This way, you don’t have to mark them manually and you can do the process much faster.
