DislikedJaro what charting platform do you use?
Here's mt4, right click on your chart, and click on properties, it will bring up this box, you can set the scale..... here i set the scale to 500 pips, width is set to 500 bars. Having your chart square is not a prerequisite, but if you use same similar scales and widths for your charts it will help you....Ignored
I give set significant high and low to the diagonal square.
