A tick represents the standard upon which the price of a security may fluctuate. The tick provides a specific price increment, reflected in the local currency associated with the market in which the security trades, by which the overall price of the security can change. Investments may have different potential tick sizes depending on the market in which they participate. The term tick also describes the direction of the price of a stock, with an uptick indicating a trade where the transaction has occurred at a price higher than the previous transaction, and a downtick indicating a transaction that has occurred at a lower price. Tick size is the minimum amount a security can move in price on an exchange. It is expressed in decimal points.

One-minute charts are popular among day traders but aren’t the only option. The bars on a tick chart are created based on a particular number of transactions.
For example, a 512 tick chart creates a new bar every 512 transactions. Customize tick charts to the number of transactions you want, for example, 5 ticks or 1546 ticks. Throughout the day there are active and slower times, where many or few transactions occur. Therefore, the x-axis typically isn’t uniform with ticks charts. For example, when a market opens several ticks bars within the first minute or two may show multiple price swings which can be used for trading purposes.
