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.
