Volatility is a market pulse, like breathing. And it's deviations is being considered as a signal attenuation.
When You want to know how far is the current price of it's mean value, You can use this indicator to determine 3-sigma rule.
The mean line (like moving average) shows if the market is in it's UpTrend state or the DownTrend state.
When it hits it's upper level - so we can say that the Uptrend has ended. The vice versa for the DownTrend.
Use it with the faster tuning when You trade the higher timeframes, and with the slower tuning on a lower timeframes.
