CKSDHi. It's simply histogram that shows divergence between the lines of the Chande Kroll Stop ind (built-in TradingView ind). I noticed that the lines intersect or are very close to each other if the volatility decreases. You can use MA like the main line or just 5, 10 lines how I do. Sorry for code Im not a programmer

This indicator was developed and described by Tushar S. Chande and Stanley Kroll in their book "The New Technical Trader" (1994, Chapter 5: New Momentum Oscillators).
Dynamic Momentum Index (DMI) Backtest This indicator plots Dynamic Momentum Index indicator. The Dynamic Momentum 
 Index (DMI) was developed by Tushar Chande and Stanley Kroll. The indicator 
 is covered in detail in their book The New Technical Trader.
 The DMI is identical to Welles Wilder`s Relative Strength Index except the 
 number of periods is variable rather than fixed. The variability of the time 
 periods used in the DMI is controlled by the recent volatility of prices. 
 The more volatile the prices, the more sensitive the DMI is to price changes. 
 In other words, the DMI will use more time periods during quiet markets, and 
 less during active markets. The maximum time periods the DMI can reach is 30 
 and the minimum is 3. This calculation method is similar to the Variable 
 Moving Average, also developed by Tushar Chande.
 The advantage of using a variable length time period when calculating the RSI 
 is that it overcomes the negative effects of smoothing, which often obscure short-term moves.
 The volatility index used in controlling the time periods in the DMI is based 
 on a calculation using a five period standard deviation and a ten period average 
 of the standard deviation.
