The paper compares the properties of market dynamics, under different trading protocols. At an empirical level, we present some evidence stemming from the comparison between different intra-daily trade regimes within the world largest Stock Exchanges. Such evidence also motivates the investigation of the properties of an agent-based model under three alternatives market mechanisms, namely a Walrasian auction, a batch auction and an 'order-book' double auction. The results highlight the importance of market mechanisms per se, even when holding constant the behavioural characteristics of the agents.
