ADX and DI (Average Directional Index) - CORRECT FORMULA

So... the popular version of "ADX and DI" shown on tradingview by masanakamura uses some wacky and incorrect formula for DI and uses SMA instead of the Wilder's MA that ADX/DI is supposed to use, and doesn't give the correct ADX and DI values. The Tradingview "Average Directional Index" uses the correct calculation but doesn't show DI+ and DI-. So, here it is with the DI+ and DI- visible. Enjoy!
