## Ease of Movement (EOM)

### Description

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.

### Formula

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:

$EOM_{n-period MA} = MA(EOM_{1})$
