Im just puzzled why these programs will have 2 different formulas. I thought ADX was a standard formula, where you can change variables, but once these variables are the same it should come out the same.
I’ve never used an ADX before so I don’t know if those discrepancies are relatively small or gigantically huge.
If they are just minor differences the problem could be caused by different broker time zones (which can make higher timeframe candles look different), or by one of the brokers disregarding Sunday data while the other is using it in their calculations.
These are the two most common reasons for differences in calculations between brokers.
