Trading Index. A market indicator used in technical analysis, calculated as...

same as Arms Index

A market indicator used in technical analysis also known as ARMS, calculated as follows: Arms Index = ((# of advancing issues / # of declining issues) / (Total up volume / Total down volume)). A value of less than 1 is considered bullish, greater than 1 bearish. Triple witching - Once every quarter — on the third Friday of March, June, September, and December — options, index options, and futures contracts expire on the same day in the U.S. In the past, when they expired at the same hour of the day, trading could be extremely volatile. But in recent years, the timing has been adjusted so that they expire at different times throughout the day, somewhat reducing the potential frenzy of trading.

Name derived from TRading INdex. Also known as an ARMS index. The index is usually calculated as the number of advancing issues divided by the number of declining issues. This, in turn, is divided by the advancing volume divided by the declining volume. If there is considerably more advancing volume relative to declining volume this will tend to reduce the index (i.e. increase the denominator). Hence, a value less than 1.0 is bullish while values greater than 1.0 indicate bearish demand. The index often is smoothed with a simple moving average.

Used in the context of general equities. Short term trading index which shows a minute-by-minute correlation of the ratio of advances to declines to the ratio of advancing volume to declining volume. Depicts whether changes in the relationship of advances and declines are taking place faster or slower than changes in the general volume movement of the market, 1 indicates a bull market, = 1 neutral, and 1 bear market. See a/d.

A measure of stock market strength that relates the number of stocks that advanced or declined to the total number of shares that advanced or declined. A trin under 1.00 is bullish and a trin over 1.00 is bearish. See: Bear Market; Bull Market

See Arms Index Trix-The one-period difference of the triple exponential smoothing operating on the log of price.
