Term: ARMS INDEX

Also known as TRading INdex (TRIN): An advance/decline stock market indicator. A reading of less than 1.0 indicates bullish demand, while greater than 1.0 is bearish. The index is often smoothed with a simple moving average. Richard Arms developed the TRIN, or Arms index, as a contrarian indicator to detect overbought and oversold levels in the market. Because of its calculation method, the TRIN has an inverse relationship with the market. Generally, a rising TRIN is bearish and a falling TRIN is bullish. Sometimes you will see the scale of the TRIN inverted to reflect this inverse relationship. The TRIN is the advance/decline ratio divided by the advance volume/decline volume ratio.
