    Syntax

    DI_NEG(close; high; low; period)

    Arguments

    The first three arguments are arrays:

      • 'close' contains the closing prices
      • 'high' contains the high prices
      • 'low' contains the low prices

    The 'period' argument defines the period for the function. It must be a constant greater than or equal to 1.

    Result

    The result is an array. The first 'period' elements are marked as invalid. 

    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_NEG function uses the modified moving average.
