Download or read book Order Flow and Liquidity Provision written by Álvaro Cartea and published by . This book was released on 2015 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: We show how to optimally take positions in the limit order book by placing limit orders at-the-touch when the midprice of the asset is affected by the trading activity of the market. The midprice dynamics have a short-term-alpha component which reflects how instantaneous net order-flow, the difference between the number of market buy and market sell orders, affects the asset's drift. If net-order flow is positive (negative), so short-term-alpha is positive (negative), the strategy may even withdraw from the sell (buy) side of the limit order book to take advantage of inventory appreciation (depreciation) and to protect the trading strategy from adverse selection costs.
Download or read book Liquidity Provision in a Limit Order Book Without Adverse Selection written by Onur Bayar and published by . This book was released on 2013 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this paper, we develop a dynamic model of a limit order market populated with liquidity traders who have only private values. We characterize and analyze the equilibrium order placement strategies of traders and the conditional execution probabilities of limit orders as a function of traders' liquidity demand and the state of the limit order book. We solve for the equilibrium of the model numerically, and analyze its properties by performing comparative dynamics analysis. Our analysis shows that changes in the steady state of the limit order book and optimal order placement strategies reflect corresponding changes in the trade-off between order execution risk and the size of potential trading gains. The equilibrium order flow depends on the current state of the limit order book since a trader's optimal trading strategy is largely affected by the time and price priorities of the existing limit orders in the book. We demonstrate how changes in the dispersion of traders' private values affect optimal trading strategies and conditional execution probabilities of limit orders. Our main result is that the dispersion in private values across traders has a significant impact on the stationary state of the equilibrium limit order book and the average bid-ask spread. A wider distribution of private values leads to more order placement at prices away from the consensus value, and therefore, to a larger bid-ask spread. Further, our numerical simulations show that extending the life span of limit orders reduces the average bid-ask spread observed in equilibrium. Finally, we find that the equilibrium percentage of market order submissions is also increasing in the dispersion in liquidity traders' private values.

This book was released on 2006-10-16 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: On April 29, 2003, the Zicklin School of Business hosted a trading conference titled, Coping With Institutional Order Flow. This conference was electronically recorded and later transcribed for this book. The text includes the edited transcript of the panel discussions and separate presentations by two major industry executives, Richard Ketchum' and Robert Mc Sweeney. As with the other volumes in this popular series, this book is not simply intended to be an historical record of the conference. We have edited the manuscript for clarity, perspective and context. New material was gathered in subsequent interviews with many of the panelists. Consequently, some remarks and passages in the text were altered and expanded and many footnotes were introduced. Our goal was to flesh out the dialogue and presentations and to keep the material as contemporary as possible. In doing so, we went to great lengths to preserve the essential nature of the original debate. We worked closely with the panelists in the editing process and took pains not to distort the meaning of their remarks. They have all approved the final draft of the manuscript. We thank them for their assistance and patience. \n my opening remarks at the conference, I suggested that effective handling of institutional order flow is one of the most important and difficult At the time of the conference, Richard Ketchum was President and Deputy Chairman at The Nasdaq Stock Market, Inc. Preface xiv challenges facing our equity markets today.
Download or read book Liquidity Based Competition for Order Flow written by Duane J. Seppi and published by . This book was released on 1998 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We present a microstructure model of competition between exchanges for order flow based on liquidity provision. Different pairings of pure limit order markets (PLM) and hybrid specialist/limit order markets (HM) are considered. We find that neither a pure nor a hybrid market structure is competition-proof. A PLM can always be supported in equilibrium as the dominant market (i.e., where the hybrid limit book is empty), but a HM can also be supported for some market parameterizations, as the dominant market. We also have examples of co-existence of competing markets. Order preferencing -- i.e., decisions about where orders are routed when investors are indifferent -- is a key determinant of market viability. Welfare comparisons show that competition between exchanges often, but not always, reduces the cost of liquidity.

Available in PDF, EPUB and Kindle. Book excerpt: This open access book addresses four standard business school subjects: microeconomics, macroeconomics, finance and information systems as they relate to trading, liquidity, and market structure. It provides a detailed examination of the impact of trading costs and other impediments of trading that the authors call rictions It also presents an interactive simulation model of equity market trading, TraderEx, that enables students to implement trading decisions in different market scenarios and structures. Addressing these topics shines a bright light on how a real-world financial market operates, and the simulation provides students with an experiential learning opportunity that is informative and fun. Each of the chapters is designed so that it can be used as a stand-alone module in an existing economics, finance, or information science course. Instructor resources such as discussion questions, Powerpoint slides and TraderEx exercises are available online.

Download or read book Econometrics of Financial High Frequency Data written by Nikolaus Hautsch and published by Springer Science & Business Media. This book was released on 2011-10-12 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: The availability of financial data recorded on high-frequency level has inspired a research area which over the last decade emerged to a major area in econometrics and statistics. The growing popularity of high-frequency econometrics is driven by technological progress in trading systems and an increasing importance of intraday trading, liquidity risk, optimal order placement as well as high-frequency volatility. This book provides a state-of-the art overview on the major approaches in high-frequency econometrics, including univariate and multivariate autoregressive conditional mean approaches for different types of high-frequency variables, intensity-based approaches for financial point processes and dynamic factor models. It discusses implementation details, provides insights into properties of high-frequency data as well as institutional settings and presents applications to volatility and liquidity estimation, order book modelling and market microstructure analysis.
Download or read book Limit Order Books written by Frédéric Abergel and published by Cambridge University Press. This book was released on 2016-05-09 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: A limit order book is essentially a file on a computer that contains all orders sent to the market, along with their characteristics such as the sign of the order, price, quantity and a timestamp. The majority of organized electronic markets rely on limit order books to store the list of interests of market participants on their central computer. A limit order book contains all the information available on a specific market and it reflects the way the market moves under the influence of its participants. This book discusses several models of limit order books. It begins by discussing the data to assess their empirical properties, and then moves on to mathematical models in order to reproduce the observed properties. Finally, the book presents a framework for numerical simulations. It also covers important modelling techniques including agent-based modelling, and advanced modelling of limit order books based on Hawkes processes. The book also provides in-depth coverage of simulation techniques and introduces general, flexible, open source library concepts useful to readers studying trading strategies in order-driven markets.
Download or read book Liquidity Provision with Limit Orders and a Strategic Specialist written by Duane J. Seppi and published by . This book was released on 1997 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents a microstructure model of liquidity provision in which a specialist with market power competes against a competitive limit order book. General solutions, comparative statistics and examples are provided first for markets with uninformative orders and then when order flows are informative. The model is also used to address two optimal market design issues. The first is the effect of quot;tickquot; size -- e.g., eighths versus decimal pricing -- on market liquidity. Institutions trading large blocks are shown to have a larger optimal tick size than small retail investors, but both prefer a tick size strictly greater than zero. Second, a hybrid specialist/limit order market (like the NYSE) provides better liquidity to small retail and institutional trades, but a pure limit order market (like the Paris Bourse) may offer better liquidity on midsize orders.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Dark Trading at the Midpoint written by Robert P. Bartlett III and published by . This book was released on 2015 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using over eight trillion observations of market data, we use a regression discontinuity design to analyze the effect of increasing the minimum price variation (MPV) for quoting equity securities in light of recent proposals to increase the MPV from $0.01 to $0.05. We show that a larger MPV encourages investors to trade in dark venues at the midpoint of the national best bid and offer. Enhanced order flow to dark venues reduces price competition by exchange liquidity providers, especially those using high frequency trading (HFT). Trading in dark venues due to a wider MPV reduces volatility and increases trading volume.
Download or read book The Evolution of Informed Liquidity Provision and Consumption written by David E. Allen and published by . This book was released on 2018 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: We investigate the provision of liquidity by different trader types on the Australian Securities Exchange using data that spans an extended sample period of 2003 to 2012. We find the familiar intraday U-shaped pattern in order volume and frequency where the lunch time session is associated with a lower level of order placement activity. We also find institutional traders use more limit orders than market orders and that their relative use of limit to market orders is higher than retail traders. The use of limit orders by institutional traders has increased substantially in 2009 and reflects the growth in algorithmic and high frequency trading. The size of the orders used by institutional traders is reduced dramatically over the years. The VAR analysis on the order choice of institutional and retail traders shows high tendency of clustering in liquidity provision even after controlling for time-of-the-day effect and market conditions. Market depth affects institutional traders' order choice but not that of retail traders. When studying the price impact of market orders, we find institutional traders are better informed than retail traders. While we do not find the provision of liquidity by institutional traders to be driven by information for all years, there is some evidence of informational liquidity provision in 2006 and 2009 and it tails off in 2012.
Download or read book Competing Market Makers Liquidity Provision and Bid Ask Spread written by Oleg Bondarenko and published by . This book was released on 2014 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper develops a dynamic market microstructure model of liquidity provision in which M strategic market makers compete in price schedules for order flow from informed and uninformed traders. In equilibrium, market makers post price schedules that are steeper than efficient ones, and the market bid-ask spreads can be decomposed into two components, one due to adverse selection and the other due to imperfect competition. At any time, the two components are proportional to each other with a coefficient of proportionality depending on M. Several testable hypothesis are derived regarding the time-series and cross-sectional properties of prices and the bid-ask spreads. In particular, a new empirical measure of market competitiveness is proposed which can be estimated from the history of transaction prices and trading volumes. Finally, the properties of continuous market are also investigated.
Download or read book Market Microstructure In Practice Second Edition written by Charles-albert Lehalle and published by World Scientific. This book was released on 2018-01-18 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book exposes and comments on the consequences of Reg NMS and MiFID on market microstructure. It covers changes in market design, electronic trading, and investor and trader behaviors. The emergence of high frequency trading and critical events like the'Flash Crash' of 2010 are also analyzed in depth.Using a quantitative viewpoint, this book explains how an attrition of liquidity and regulatory changes can impact the whole microstructure of financial markets. A mathematical Appendix details the quantitative tools and indicators used through the book, allowing the reader to go further independently.This book is written by practitioners and theoretical experts and covers practical aspects (like the optimal infrastructure needed to trade electronically in modern markets) and abstract analyses (like the use on entropy measurements to understand the progress of market fragmentation).As market microstructure is a recent academic field, students will benefit from the book's overview of the current state of microstructure and will use the Appendix to understand important methodologies. Policy makers and regulators will use this book to access theoretical analyses on real cases. For readers who are practitioners, this book delivers data analysis and basic processes like the designs of Smart Order Routing and trade scheduling algorithms.In this second edition, the authors have added a large section on orderbook dynamics, showing how liquidity can predict future price moves, and how High Frequency Traders can profit from it. The section on market impact has also been updated to show how buying or selling pressure moves prices not only for a few hours, but even for days, and how prices relax (or not) after a period of intense pressure.Further, this edition includes pages on Dark Pools, Circuit Breakers and added information outside of Equity Trading, because MiFID 2 is likely to push fixed income markets towards more electronification. The authors explore what is to be expected from this change in microstructure. The appendix has also been augmented to include the propagator models (for intraday price impact), a simple version of Kyle's model (1985) for daily market impact, and a more sophisticated optimal trading framework, to support the design of trading algorithms.
Download or read book The Adaptive Nature of Liquidity Taking in Limit Order Books written by Damian Taranto and published by . This book was released on 2016 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: In financial markets, the order flow, defined as the process assuming value one for buy market orders and minus one for sell market orders, displays a very slowly decaying autocorrelation function. Since orders impact prices, reconciling the persistence of the order flow with market efficiency is a subtle issue. A possible solution is provided by asymmetric liquidity, which states that the impact of a buy or sell order is inversely related to the probability of its occurrence. We empirically find that when the order flow predictability increases in one direction, the liquidity in the opposite side decreases, but the probability that a trade moves the price decreases significantly. While the last mechanism is able to counterbalance the persistence of order flow and restore efficiency and diffusivity, the first acts in opposite direction. We introduce a statistical order book model where the persistence of the order flow is mitigated by adjusting the market order volume to the predictability of the order flow. The model reproduces the diffusive behaviour of prices at all time scales without fine-tuning the values of parameters, as well as the behaviour of most order book quantities as a function of the local predictability of order flow.
Download or read book Trades Quotes and Prices written by Jean-Philippe Bouchaud and published by Cambridge University Press. This book was released on 2018-03-22 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: The widespread availability of high-quality, high-frequency data has revolutionised the study of financial markets. By describing not only asset prices, but also market participants' actions and interactions, this wealth of information offers a new window into the inner workings of the financial ecosystem. In this original text, the authors discuss empirical facts of financial markets and introduce a wide range of models, from the micro-scale mechanics of individual order arrivals to the emergent, macro-scale issues of market stability. Throughout this journey, data is king. All discussions are firmly rooted in the empirical behaviour of real stocks, and all models are calibrated and evaluated using recent data from Nasdaq. By confronting theory with empirical facts, this book for practitioners, researchers and advanced students provides a fresh, new, and often surprising perspective on topics as diverse as optimal trading, price impact, the fragile nature of liquidity, and even the reasons why people trade at all.
