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
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!
