Average Directional Movement Index Wilder (ADX Wilder) helps to determine if there is a market trend.
This technical indicator is constructed as a strict correspondence with the algorithm described by Welles
Wilder in his book "New concepts in technical trading systems".
Trading rules of this indicator are described in the Average Directional Movement Index.
First positive (dm_plus) and negative (dm_minus) changes at each bar are calculated, as well as the true range tr:
If Low(i-1) - Low(i) > 0 dm_minus(i) = Low(i-1) - Low(i), otherwise dm_minus(i) = 0.
tr(i) = Max(ABS(High(i) - Low(i)), ABS(High(i) - Close(i-1)), ABS(Low(i) - Close(i-1)))
After that the smoothed values are calculated: Plus_D(i), Minus_D(i) and ATR():
Now Directional Movement Index - DX(i) - is calculated:
After preliminary calculations we obtain the value of the ADX(i) indicator on the current bar by smoothing DX index values:
