This refers to a financial indicator that shows the the number of stocks, or any other financial security, in an index that during any particular moment of the day are trading above or below their last closing price. It is calculated simply by subtracting the number of stocks showing downticks from the number of stocks that are showing upticks during the day. The tick index is one of the many indicators used by traders to gauge the general mood of the market. It gives traders a good idea of the general breadth of a market advance or decline, which can have an impact on their trades.
