Indicator: Volatility Quality Index [VQI]

Volatility Quality Index ( VQI ), by Thomas Stridsman, points out the difference between bad and good volatility in order to identify better trade opportunities in the market.

This plots 3 lines:
- Red line is the VQI (actually, sum of VQI ).
- Green line is the 9-period SMA of sum_of_VQI.
- Orange line is the 200-period SMA of sum_of_VQI.

Stridsman suggested to buy when VQI has increased in the previous 10 bars (use the SMAs ) and sell when it has decreased in the previous 10 bars. IMO, use this with your other indicators as a confirmation signal.
