Ease of Movement (EMV)
An indicator relating price change to volume, showing how easily price moved — a large move on low volume signals 'ease,' a small move on high volume doesn't.
Ease of Movement (EMV), developed by Richard Arms, relates how far price moved during a period to how much volume it took to move it that far, producing a reading that's high when price moves a large distance on relatively low volume, and low when a large volume produces only a small price move.
The underlying idea is that price moving easily (a large move on light volume) reflects less resistance than price that struggles to move despite heavy volume. See Kaavon's dedicated EMV article for the full calculation.
Examples
- A high EMV reading means price moved a large distance on comparatively light volume — moving "easily," in the indicator's own terms.
- A low or negative EMV reading, despite heavy volume, can suggest price is meeting more resistance to further movement.
