Why use it. Bitfinex's margin book is one of the longest-running gauges of leveraged spot positioning: large accounts there have often added longs into falls and the shorts have been squeezed in sharp rallies. How to read it. Read the two lines and their changes: longs climbing while the price falls is dip buying with leverage; a sudden drop in shorts during a rally is short covering.
