How to Fix the Scale in MT4 (Windows)
The price scale on MT4 charts 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 "Fix scale" under the "Common" tab and specify the price range to display.
How to set the scale to a 1:1 ratio
In the "Properties" window, check "Fix scale 1:1" under the "Common" tab to fix the horizontal (time) and vertical (price) axes in 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 indicated by the slightly thicker part of the scale line.
