Demonstrated through controlled laboratory experiments that continuous double auctions produce rapid price discovery and approximate competitive equilibria even with few traders and private information. Experimental protocols specified order types, matching rules and timing, producing replicable evidence that a continuous trading mechanism supports liquidity and efficient allocation. Influence reached market operators and market‑microstructure theorists by providing concrete experimental evidence justifying order‑driven designs and limit‑order procedures used in electronic exchanges. Experimental specifications—such as bid/ask submission rules, matching priority and information feedback—offered implementable parameters that informed exchange software and rulesets used by automated trading venues. Effects include impacting how academics and practitioners evaluate liquidity provision, how exchanges calibrate matching engines, and how regulators assess the resilience of order‑driven markets. Published experimental protocols and replications created a documented bridge between laboratory results and real‑world exchange mechanisms, directly affecting the practical design choices that govern trading liquidity.
