This refers to a change in the price of a security. An uptick occurs when the last trade in a security takes place at a higher price than the prior trade. A downtick occurs when the last trade in a security takes place at a lower price than the prior trade. An indicator may be fashioned from the difference between the number of NYSE issues showing upticks on the last trade and the number of NYSE issues showing downticks on the last trade. This indicator is known as the TICK, and is found on many quote screens. A TICK of +236 means 236 more NYSE issues last traded on upticks than those trading on downticks.
