Directional Movement Index​

The Directional Movement Index (DX) is a technical indicator used in financial markets to measure the strength of a trend. It is a part of the Directional Movement System, which was developed by J. Welles Wilder.

Description​

The DX indicator is used to determine the strength of a trend by comparing the gains and losses of an asset over a specified period. It is calculated based on the Positive Directional Indicator (+DI) and Negative Directional Indicator (-DI) lines, which are derived from the highs, lows, and closes of the asset.

What does this worker do?​

This worker calculates the Directional Movement Index (DX) for a given set of high, low, and close prices over a specified period. It takes into account the time period for which the calculation is to be performed and returns the DX values.

How to interpret the results​

The DX indicator ranges from 0 to 100. A high DX value indicates a strong trend, while a low DX value indicates a weak or absent trend. Typically:

  • A DX value above 25 indicates a strong trend.
  • A DX value below 20 indicates a weak or absent trend.
