After downloading the MT4, when you draw a trendline, the platform will project it infinitely on the right side of the chart. It means it has the “Ray” option activated, and you’ll need to get rid of it asap.
To do that:
- draw a trendline on a chart using the “Draw trendline” option from the shortcuts menu
- select it with the mouse
- right click on it
- open the Parameters tab
- un-check the Ray option
From this moment on, the trendline will have the exact length you want it to have. Just click and drag it from and to any point on the chart.
