MT4 ADX different from Oanda ADX

[Mikeel1987]

Does anyone know how to get the same ADX value on the MT4 platform as in the Oanda Desktop platform?  It seems verry different with same parameters.  The Mt4 version isn't working for me.  I need to get a similar value as the Oanda desktop version.  the only way I can think of doing that is by getting the formula and programing that manually.  Problem is I don't know the formula.  Oanda isn't helpful either.  Any ideas?

yes for the standard ADX.  it does not appear they use that formula.

Here is the indicator formula they use.
Also same as the one in Tradestation, Multicharts and Trading View.
