High-Frequency Data

Definition

High-frequency data refers to information collected and updated at very short intervals, often milliseconds or seconds, capturing rapid changes in market conditions or system states. In digital asset markets, this data includes granular price movements, order book changes, and transaction volumes recorded with extreme precision. It is essential for quantitative analysis, algorithmic trading, and real-time decision-making due to its detailed and immediate nature. This type of data provides a fine-grained view of market dynamics.
