Arms Ease of Movement

Arms Ease of Movement was developed by Richard W. Arms, Jr., this analysis routine expands on Mr. Arms' Equivolume charting tool by quantifying the shape aspects of the plotted boxes. The purpose of this quantifying is to determine the ease, or lack thereof, with which a particular issue is able to move in one direction or another. The ease with which an issue moves is a product of a ratio between the height ( trading range ) and width ( volume ) of the plotted box. In general, a higher ratio results from a wider box and indicates difficulty of movement. A lower ratio results from a narrower box and indicates easier movement. This ratio is then related to a comparison between today's and yesterday's trading-range midpoint values to determine the ease of movement value ( EMV ). A moving average is then applied to the EMV value - the moving average period can be varied in order to make the EMV flexible as a trading tool.
