Market microstructure analyzes the granular mechanisms through which buy and sell orders translate into recorded transaction prices. It encompasses exchange matching engine latency, tick sizes, order flow toxicity, hidden liquidity (iceberg orders), and the interplay between spot trading and derivatives venues.
