We propose a model for the dynamics of a limit order book in a liquid market where buy and sell orders are submitted at high frequency. We derive a functional central limit theorem for the joint dynamics of the bid and ask queues and show that, when the frequency of order arrivals is large, the...

This paper examines whether NASDAQ dealers' preopening quotes might be related to non-fundamental information, that is, information about transient trading pressure unrelated to fundamentals. Preopening quotes posted by wholesalers (dealers specialized in market-making and thus presumably more...

To execute a trade, participants in electronic equity markets may choose to submit limit orders or market orders across various exchanges where a stock is traded. This decision is influenced by the characteristics of the order flow and queue sizes in each limit order book, as well as the...

We show that the distribution of trading volume in call auctions is indicative of the proportion of informed trade. We use the Kyle (1985) model to predict the shape of the volume distribution as a function of the proportion of informed trade. If most liquidity demanders are uninformed, there is...

The efficient frontier is a core concept in Modern Portfolio Theory. Based on this idea, we will construct optimal trading curves for different types of portfolios. These curves correspond to the algorithmic trading strategies that minimize the expected transaction costs, i.e. the joint effect...

We analyze a new blue chips (large caps) stock index for France from 1854 to 1998. We detail its methodology and show that it differs profoundly from earlier indices, and that it is more consistent with the French financial and economic history. We suggest this result casts some doubt on many...
