A "tick" in the context of financial markets refers to the smallest possible change in the price of a financial instrument. This variation can be either upwards or downwards and is fundamental to understanding how prices move within stock markets, futures, currencies, among others. The magnitude of a tick varies depending on the market and the financial instrument in question, being stipulated by the stock exchange or the corresponding regulatory entity.

The evolution and popularization of the tick concept are closely linked to the technological development of trading platforms and the digitization of financial markets. Previously, price fluctuations were measured in larger fractions, but with the advancement of technology, greater precision and speed in order execution have been allowed, which in turn has fostered the creation of high-frequency trading strategies that exploit minimal price variations

Key elements that compose the notion of a tick include its monetary value (which determines the minimum profit or loss per contract or share), its impact on market liquidity and volatility, and its relevance in formulating trading strategies. The main roles related to the tick concept are traders (who must understand how it affects their operations), market makers (who provide liquidity by taking advantage of minimal price changes), and regulators (who define the tick size for each instrument).

To begin understanding and applying the tick concept in trading, it is crucial to familiarize oneself with the contract specifications of the financial instruments being traded, understanding how tick size affects trading strategy and risk management. Modern trading tools and platforms provide detailed information on tick sizes for various instruments, as well as offering simulations and testing environments for beginners to experiment with without real risk. Essential resources for learning more about ticks and their application include online tutorials, specialized webinars, and trading communities where strategies can be shared and advice from experienced traders obtained.

For beginners, it is important to start by understanding how tick size affects the positions taken and how to incorporate this understanding into risk management. Continuous practice and ongoing education are essential for developing an effective trading strategy that takes into account tick dynamics in financial markets.
