Because the quoted price depends only on the pool balances, it drifts away from prices on larger venues until arbitrage traders swap in the correcting direction and restore alignment. An automated market maker differs from a human market maker in that it quotes mechanically and continuously, forms no view on value, and cannot withdraw its quotes during stress.
Na prática

Aggregators and routers create double counting when a single order…
