Ease of Movement (EOM)

Ease of Movement, developed by Richard W. Arms, Jr., relates price change to volume and is particularly useful for assessing the strength of a trend. High positive values indicate the price is increasing on low volume and strong negative values indicate the price is dropping on low volume.

Configuration Options

  • Period: Number of bars to use in the calculations.
  • Moving Average Type: Type of moving average to use in the calculations:
    • Simple
    • Exponential
    • Time Series
    • Triangular
    • Variable
    • VIDYA
    • Weighted
    • Welles Winder
    • Hull
    • Double Exponential
    • Triple Exponential
  • Color Selectors: Colors to use for graph elements.
  • Display Axis Label: Whether to display the most recent value on the Y axis.


The four calculation below are required for Ease of Movement indicator:

\[Distance\;Moved = DM = \left(\frac{High_{current} - Low_{current}}{2}\right) - \left(\frac{High_{previous} - Low_{previous}}{2}\right) \]

\[Box Ratio = BR = \left(\frac{\frac{Volume_{current}}{1,000,000,000}}{High_{current} - Low_{current}}\right) \]

Calculate a one period EOM:

\[EOM_{1} = \frac{DM}{BR}\]

Calculate the moving average where the user can pick from various moving average types:

\[EOM_{n-period MA} = MA(EOM_{1})\]
