What it does
Ease of Movement (EOM), developed by Richard Arms, measures how easily price advances or declines relative to the volume required to move it. Each bar's distance moved (the change in the high-low midpoint from the prior bar) is divided by a box ratio of volume relative to the bar's range, and the result is usually smoothed with a 14-period moving average. Large positive values mean price rose easily on light volume; large negative values mean it fell easily.
How to add it
Click Indicators (ƒx) in the header.
Search “Ease Of Movement” and click the result.
Hover its legend row and click the gear to open settings.
How traders use it
- Readings above zero suggest price is rising with little resistance, supporting long positions; readings below zero suggest easy downside movement.
- Zero-line crossovers of the smoothed EOM can act as trend-following entries, best taken in the direction of the larger trend.
- A strong price advance with EOM barely positive means heavy volume was needed for little progress, a sign of distribution and a warning for longs.
- Combine with a volume indicator such as OBV or with support and resistance levels to confirm whether an easy move has room to continue.

Tips
- Double-click the plot to open settings directly, skipping the legend hover.
- The pane keeps its height in saved layouts, so size it once and it survives reloads.
- Resize the pane by dragging its divider; collapse it from the legend row when you need the space back.
Watch out for
- It depends on reliable volume data, so it is unreliable on spot forex, indices without consolidated volume, or thinly traded instruments.
- The smoothing that makes it readable also adds lag, and it whipsaws around zero in choppy markets.
