Quote Stuffing
Quote stuffing is a manipulative practice of rapidly submitting and cancelling large numbers of orders to clog the order book or data feed and slow down or confuse other participants.
Quote stuffing is prohibited in India and is one of the abuses the order-to-trade ratio penalties and surveillance systems are designed to deter. By flooding the system with orders that are never meant to trade, a manipulator can create latency for rivals or false impressions of liquidity.
Exchanges and SEBI monitor for abnormal messaging patterns, and the graded OTR charges raise the cost of excessive order traffic. Legitimate market making also posts and cancels many orders, so surveillance must distinguish genuine liquidity provision from manipulative stuffing.
