Pegged Limit Orders

Abstract

Limit orders face mispricing risk - the risk of executing at a stale limit price after an innovation in public valuation, because limit-order traders generally do not continuously monitor market conditions. We analyze the impact of pegged limit orders that automatically adjust the limit price in a hybrid market. We find the direct effect is to increase limit-order profits, reduce dealer profits, and increase market-order losses. However, the indirect effect is to increase the quantity of limit orders submitted. A numerical calibration finds that when dealers supply relatively little liquidity, there is a net benefit to market orders as well.
