Strategic Foundation for the Tail Expectation in Limit Order Book Markets
A Talk by Dr. Lawrence R. Glosten
Abstract
We analyze the strategic interactions of liquidity suppliers quoting on a limit order book. In an environment with noise traders and informed traders trading on news we show that there is an equilibrium that feature quoters using mixed strategies; each offering the same quantity of shares at random prices (and, of course, random bid prices). These random prices with the associated quantities form the market quotes and the depth of book, or price schedule. There are equilibria with a smaller number of quoters quoting a larger number of shares and equilibria with a larger number of quoters quoting a smaller number of shares. Considering a sequence of equilibria with the number of quoters getting large, we establish that the stochastic equilibrium price schedule converges to the zero profit deterministic competitive price schedule. An offer (or bid) is characterized as the expectation of the future value conditional on the offer being picked off by a larger buy (or sell) order.
