Tick Data Granularity

Tick data granularity refers to the level of detail captured in a historical record of every individual trade and quote change within a market. Unlike aggregate candle charts, tick data records the exact price, volume, and timestamp of every transaction as it occurs.

In quantitative finance, this high-resolution data is vital for backtesting strategies, calculating risk sensitivities, and analyzing market microstructure. High granularity allows researchers to reconstruct the order book at any given moment, providing insight into how liquidity evolves during periods of high volatility.

For cryptocurrency derivatives, where market moves can be rapid and extreme, tick data is the primary tool for identifying patterns in order flow and verifying the execution quality of trading algorithms. Without such granular data, understanding the mechanics of price discovery becomes impossible.
