TRIN (finance)

The TRIN, or Arms index is a short-term technical analysis stock market trading indicator. The name is short for TRading INdex. The index is calculated as follows:

:$TRIN\; =\; frac\; \{advancing\; issues/declining\; issues\}\; \{advancing\; volume/declining\; volume\}$

A value below 1 usually indicates bullish sentiment, and a value above 1 – bearish. The index was introduced by Richard Arms, and is continuously displayed during trading hours, among other indices, on the New York Stock Exchange's central wall display for the stocks traded on that exchange.
