Volatility Contraction Scanner

[Harry H-1789032205854]

Hi team,

This query pertains the Volatility Contraction Scanner found in RZone
Path: RZone -> P&F Smart Scanner -> Volatility Contraction Scanner

I want to know the logic used in this scanner. There is no information in the tooltip on RZone, nor is there any link on Insight/Shelf related to the logic used. I understand the VCP pattern, but I can't make much sense of the output. The DTB and DBS level shown in the screener don't match the P&F chart either.

Thanks
