(((If prices are flat or ranging, it will expand all price activity and attempt to stretch it across the entire screen, making low-volatility activity seem more volatile by increasing the height of all the bars and candlesticks on the screen.

Conversely, when prices are trending, auto-scaling will shorten the height of all bars on the screen in order to fit in the trend action, making volatile price activity look less volatile. )))

can someone explain this for me

thanx!!
