Quote Stuffing Impact

Quote stuffing impact refers to the degradation of market performance caused by an overwhelming volume of rapid order cancellations and updates. This technique is used to congest the exchange's matching engine, creating latency for other participants and potentially allowing the stuffer to gain an advantage.

By filling the communication channels with noise, the attacker makes it difficult for other traders to get their orders through or to see the true state of the market. This not only creates an unfair environment but also increases the risk of systemic failure during high-volatility events.

Exchanges combat this by implementing message rate limits and charging fees for excessive cancellations. It is a key factor in understanding the limits of electronic trading infrastructure.
