numpad 5 by code (rescale y axis)

[Email Temporaire]

Good day,
for complex reason here --> https://www.mql5.com/en/forum/72215

i need to simulate numpad 5 by code (or rescale y axis).
Then my y scale is reinitialized when i change timeframe.

Is it possible ?
regards.

NB: i want to do it by code, is it even possible?

use PostMessage windows API, WM_KEYDOWN message

Require windows DLL.

Thank you.
And is there a way - by mql5 native code - to command the chart to react as if i double click the price scale ?
