Description
The +DI function is a part of the Directional Movement System developed by J. Welles Wilder.
The system consists of three lines:
-
The Positive Direction Indicator (+DI) summarizes upward trend movement;
-
The Negative Direction Indicator (-DI) summarizes downward trend movement;
-
The Average Directional Movement Index (ADX) indicates whether the market is trending or ranging. For internal calculations the DI_POS function uses the modified moving average.
