trading tick

A trading tick refers to the smallest possible price movement of a financial instrument, such as a stock or commodity. It is often used to measure the price volatility of a security or the liquidity of a market. A “tick” can refer to either an upward or downward price movement, with the direction depending on market conditions and the specific security being traded. For example, in the stock market, a “tick” may refer to a change in the stock price from $100.00 to $100.01, or from $100.01 to $100.00. Understanding the concept of trading ticks is important for traders and investors as it can help them make informed investment decisions based on the level of price volatility and market liquidity.trading tick

A trading tick is the minimum price change that a financial instrument, such as a stock or commodity, can experience. It is used as a unit of measurement for price movements and volatility in financial markets. A tick can be up or down and its value varies depending on the security being traded and market conditions. Understanding trading ticks is important for traders and investors as it helps them make informed investment decisions by considering the level of price volatility and market liquidity.

What Is a Tick?

A tick is a measure of the minimum upward or downward movement in the price of a security. A tick can also refer to the change in the price of a security from one trade to the next trade. Since 2001 and the advent of decimalization, the minimum tick size for stocks trading above $1 is one cent.

How a Tick Works

Investments may have different potential tick sizes depending on the market in which they participate. For example, the E-mini S&P 500 futures contract has a designated tick size of $0.25, while gold futures have a tick size of $0.10. If a futures contract on the E-mini S&P 500 is currently listed at a price of $20, it can move one tick upward, changing the price to $20.25 based on the $0.25 tick size minimum. However, with that minimum tick size in place, the price of the security could not move from $20 to $20.10 because $0.10 is below the minimum tick size.

In 2015, the Securities and Exchange Commission (SEC) approved a two-year pilot plan to widen the tick sizes of 1,200 small-cap stocks. This was done to promote research and trading in publicly-traded companies with market capitalization levels around $3 billion, as well as trading volumes below one million shares daily on average. The pilot looked to widen the tick size for the selected securities to determine the overall effect on liquidity.

Tick as a Movement Indicator

The term tick can also be used to describe the direction of the price of a stock. An uptick indicates a trade where the transaction has occurred at a price higher than the previous transaction and a downtick indicates a transaction that has occurred at a lower price.

Results of the SEC’s Tick Size Pilot Program

According to an article by Bill Alpert in Barron’s, called “Congress’ Failed Stock Market Experiment Cost Investors $900 Million,” the idea for increasing tick sizes for small-cap stocks originated with David Weild IV, a former Vice President at NASDAQ who is informally known as the father of the JOBS Act.5
