How to Lock the Scale on MT5 (Mac)

MT5's chart price scale is automatically adjusted based on the visible range by default, but it can be fixed to a specified price.

How to fix the price scale

Right-click on the chart and select "Properties".

In the "Properties" window, check "Scale fix" under the "Common" tab, and specify the display range with "Fixed maximum" and "Fixed minimum".

How to set the scale to a 1:1 ratio

In the "Properties" window, check "Scale fix one to one" under the "Common" tab to fix the horizontal (time) and vertical (price) axes at a 1:1 ratio.

How to adjust the display position when the scale is fixed

When the scale is fixed, a scrollbar will appear in the price scale area. You can adjust the display position by moving the scrollbar up and down.

※ The scrollbar is the slightly thicker part of the scale line.
