Has anyone coded this band idea by David Varadi?

"DV Bands are simply bollinger bands that have been normalized by ranking the current z-score using the PERCENTRANK function with a lookback of 252 days. DV bands like bollinger bands are set at 20 and 2, with 20 being the 20-day average of prices and +/- 2 standard deviations representing the upper and lower bands."

The PercentRank function was coded by DartboardTrader and could be found by searching the forum or directly in Community.Indicators (open source). As with DV2 bounded, I guess you'll need to pass each of the Bollinger Band series to PercentRank.
