The RSI Histo indicator is intgral to the 3crSquad method. It is used to identify periods of high price momentum. You can customise colours, line width and style, RSI Histo levels and more.
 
The free version allows for some customisation but does not offer a built-in divergence detector. RSI Histo divergence highlights weakening price momentum and indicates a possible trend reversal.
 
The 3crSquad method likes to see agreement between this indicator and the TMA Slope indicator to confirm a potential trend reversal.
