Volatility is a measure of a financial instrument indicating the change in the price of that instrument per unit of time. Volatility allows for the assessment of potential risks and potential profits on a given instrument. It increases with the time interval extension over which the price change is of interest. However, this relationship is nonlinear, meaning that volatility does not grow proportionally to the increase in the time interval. Besides volatility, market liquidity also affects profitability. In cases of insufficient liquidity, the execution of market orders significantly deteriorates, ultimately reducing actual volatility and, consequently, decreasing potential profits, while potential risks increase.
