I have noticed on the new Beta Module that when I am in a chart and zoom in with the mouse wheel - it is screwy. When you zoom in once, you have you zoom out 4x the amount to get back to square one. It is not like that in the non beta charts.
This happens on the vertical and horizontal scroll. Seems to be 4x to 5x on the up/down & 2x to 3x on the left/right. It would seem it you zoom out “1 click with the wheel” you should be able to zoom in “1 click” to get back to where you started.
BTW - This is on all charts (Candle, TPO, Bar, Etc)
