Optimal order display in limit order markets with liquidity competition | May 28, 2017

 and Ulrich Horst of Universität Wien and Humboldt-Universität zu Berlin published and Article in Journal of Economic Dynamics and Control (April 2015)  with the titel Optimal order display in limit order markets with liquidity competition using LOBSTER data. Abstract:
Order display is associated with benefits and costs. Benefits arise from increased execution-priority, while costs are due to adverse market impact. We analyze a structural model of optimal order placement that captures trade-off between the costs and benefits of order display. For a benchmark model of pure liquidity competition, we give a closed-form solution for optimal display sizes. We show that competition in liquidity supply incentivizes the use of hidden orders to prevent losses due to over-bidding. Thus, because aggressive liquidity competition is more prevalent in liquid stocks, our model predicts that the proportion of hidden liquidity is higher in liquid markets. Our theoretical considerations ares supported by an empirical analysis using high-frequency order-message data from NASDAQ. We find that there are no benefits in hiding orders in il-liquid stocks, whereas the performance gains can be significant in liquid stocks.

Latency and Liquidity Provision in a Limit Order Book | April 18, 2017


Julius Bonart and Martin Gould  of Imperial College London published an Article in Quantitative Finance (April 2017) using LOBSTER data titled Latency and Liquidity Provision in a Limit Order Book. Abstract:

 We use a recent, high-quality data set from Nasdaq to perform an empirical analysis of order flow in a limit order book (LOB) before and after the arrival of a market order. For each of the stocks that we study, we identify a sequence of distinct phases across which the net flow of orders differs considerably. We note some of our results are consist with the widely reported phenomenon of stimulated refill, but that others are not. We therefore propose alternative mechanical and strategic motivations for the behaviour that we observe. Based on our findings, we argue that strategic liquidity providers consider both adverse selection and expected waiting costs when deciding how to act.
