Ease of movement

How easily price moves, comparing the midpoint change with the volume needed to produce it.

Illustration of the ease of movement shape. It is a sketch, not real price data.

What it shows

Richard Arms's ease of movement divides the change in the bar's midpoint by a 'box ratio', which is volume divided by the bar's range. A big rise on low volume gives a high value. A small rise on high volume gives a low value.

It is smoothed with a 14-bar average.

How we find it

The same code that draws it on your chart follows these steps, with the same result every time.

Midpoint move = midpoint today − midpoint yesterday.
Box ratio = (volume ÷ 100,000,000) ÷ (high − low).
EMV = midpoint move ÷ box ratio.
Smooth with a 14-bar average.

Starting values: Smoothing 14 bars. These are proposed and will be tuned on real price data before launch.

How to read it

The panel shows EMV.
High positive: price rose with little volume.
Low or negative: fell, or rose with heavy volume.
