Tick Size
Tick size is the minimum price movement, or smallest increment, by which the price of a security can change in the financial markets. It represents the smallest possible change between bid and ask prices, and it varies depending on the asset class, market, and the exchange where the security is traded. Tick size is important because it affects liquidity, trading costs, and the execution of trades.
Example
In the U.S. stock market, the tick size for most stocks is $0.01, meaning the smallest price movement a stock can make is one cent.
