THE ARMS INDEX (TRIN)
An Introduction to the Volume Analysis of Stock and Bond Markets
Richard Arms is associated with Equivolume Charting and the ARMS Index. His earlier writings have
received wide attention and Equivolume Charting has been acclaimed to be "the first new method of
charting since the point and figure was introduced in the 1930s." Arm's premise is that trading volume
(especially when combined with price) is a better indicator of current market activity and portendor of
future price movements than price alone.
