Arrival Process Statistics

Calculation

Arrival process statistics, within cryptocurrency and derivatives markets, quantify the timing and frequency of order arrivals to an exchange or trading venue. These statistics are fundamental to modeling market microstructure, informing high-frequency trading strategies, and assessing liquidity risk. Accurate calculation relies on high-resolution timestamp data, often requiring specialized data handling techniques to account for network latency and clock synchronization issues inherent in decentralized systems. The resulting distributions—typically Poisson or Hawkes processes—provide insights into the predictability of order flow and potential for price impact.
