Quadratic Weighted (QWMA) MACD

MACD but on the Quadratic Weighted Moving Average instead of regular Moving Average

"The quadratic moving average ( QMA ) or quadratic weighted moving average (QWMA) is a type of moving average who is closer to the price when price is up trending. This moving average is defined as the square root of the moving average of the squared price." alexgrover (tradingview.com/script/Iw3FtbxG-QMA-SMA-Difference/)
