Range Action Verification Index (RAVI) indicator script. This indicator was originally developed by Tushar Chande (see his book "Beyond Technical Analysis: How to Develop and Implement a Winning Trading System").
This is the second version of Kay_BBands. But this is infused with ADX.
When +DI (Directional Index) is above -DI, then Upper band will be visible and vice-versa.
This is when the ADX is above the threshold. 20 is the default but can be set to 25.
When the ADX is below the specified threshold, both bands gets visible, showing no trending conditions.
