Create digonal lines between varios points

New comment

I'm trying to create a line that follows the following settings to form a triangle:


-starting from the lowest price and linking the inteception between line3 and SQ2#DOWN

-starting from the highest price and linking the inteception between line3 and SQ2#UP


the image illustrate my intention: https://charts.mql5.com/26/292/eurusd-m5-deriv-limited-3.png
