Quote Stuffing

Quote Stuffing is a form of market manipulation where a participant floods the order book with a high volume of orders and cancellations to create noise and delay the processing of other participants' orders. By overwhelming the exchange's matching engine, the manipulator creates a temporary latency advantage for themselves, allowing them to execute trades at favorable prices before the market can react.

This practice is considered predatory because it disrupts the normal flow of information and can disadvantage legitimate traders who are unable to update their positions quickly. Exchanges combat this through rigorous surveillance and the imposition of message limits.

It highlights the vulnerability of electronic markets to technical exploitation. Regulatory bodies often monitor for this activity as part of their broader mandate to protect market fairness.
