MetaTrader offers a lot of great chart studies and charting tools, but it’s very easy to lose track of what you were trying to show with the different trendlines and chart studies. You can annotate individual trendlines and then display the information right on your chart.
When creating a new trendline, enter the information you want to see on your charts under “Description” and it will show this text directly on the trendline.

When it comes to trendlines, MetaTrader has another feature. Once you have created a trendline, select it, press CTRL and MetaTrader will then copy the trendline. This is an especially helpful shortcut when it comes to drawing parallel channels or quickly creating a new line.
