Formula
TR = the true range, +DM and -DM = the larger of the two directional moves, the other is 0
+DI = 100 * smoothed(+DM) / smoothed(TR), -DI = 100 * smoothed(-DM) / smoothed(TR)
DX = 100 * |+DI - -DI| / (+DI + -DI), ADX = smoothed(DX)
mt5: smoothing with 2 / (period + 1), starting from zero. wilder: smoothing with 1 / period, starting from the mean of the first period values. Where the true range is zero the lines read 0.
