Ease of Movement (EOM)

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:

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