Book Description
We study the effects of the introduction of a call auction in the closing stages of the trading day in Borsa Italiana's (BIt) equity markets. We show that the Closing Call Auction (CCA) drastically reduces spread and volatility just before the close of trading, while having a negligible effect on the rest of the day. We attribute this change in market quality to agents' reactions to the new trading opportunity offered by the CCA. We show that the introduction of a CCA significantly reduces the cost of immediacy at the end of continuous trading, and also reduces volatility. This effect is highly concentrated in the last few minutes of continuous trading, without any discernible impact on the rest of the day. To test the robustness of our findings, we compare this outcome with that of the introduction of the CCA on Euronext Paris and find similar results. The differences can be explained in the way the two exchanges calculate the Reference Price. We also document changes in the trading aggressiveness of various types of market participants around the close.

Book Description
We study the effects of the introduction of a Closing Auction (CA) on the microstructure on the continuous trading phase in Borsa Italiana and Paris Bourse. We postulate and compare several empirical predictions based on both standard Kyle-type models and more recent models of limit order book. We find that while the CA has no effect on most of the day trading, its effect on the last minutes of trading, where the Closing Price was previously determined, is dramatic. We document a decline in volume, associated with a significant reduction in spread and volatility, and an increase in aggressiveness of liquidity suppliers. We show that the differences in the Reference Price algorithm between Milan and Paris have a significant effect: the CA attracts greater volumes when the Reference Price is equated to the CA price.

Book Description
This book is based on the proceedings of The Electronic Call Auction: New Answers to Old Questions, a conference hosted by the Zicklin School of Business on May 16, 2000. The text includes the edited transcripts of the panel discussions and separate addresses by three major industry executives Douglas M. Atkin, formerly President and CEO, Instinet Corporation; Kenneth D. Pasternak, formerly President and CEO, Knight/Trimark Group, Inc., and William J. Brodsky, Chairman and CEO, Chicago Board Options Exchange. The electronic call auction is an important trading vehicle in many market centers around the world, but is not well understood in the US. What are call auctions? How should they be designed and integrated with continuous trading in a hybrid market structure? As call auctions play a more central role in the US markets, how will they affect market quality in terms of transparency, order flow consolidation, and price discovery? These and other critical questions were asked at the conference while the efficiency of the US markets was broadly assessed.

Book Description
ROBERT A. SCHWARTZ The primary objective of this book is to consider how the inclusion of electronic call auction trading would affect the performance of our U.S. equity markets. The papers it contains focus on the call auction and its role in a hybrid market struc ture. The purpose is to increase understanding of this trading environment, and to consider the design of a more efficient stock market. This book had its origin in a symposium, Electronic Call Market Trading, that was held at New York University's Salomon Center on April 20, 1995. Nearly 150 people from 16 different countries attended. At the time, three proprietary trading systems based on call auction principles (The Arizona Stock Exchange, Posit, and Instinet's Crossing Network) had been operating for several years and interest already existed in the procedure. Since the symposium, increasing use has been made of call auctions, primarily by the ParisBourse in its Nouveau Marchi: and CAC markets, by Deutsche Borse in its Xetra market, and in the U.S. by OptiMark. Rather than being used as stand alone systems, however, call auctions are now being interfaced with continuous markets so as to produce hybrid market structures, a development that is given considerable attention to in a number of the chapters in this book.

Book Description
This paper examines the impact of closing call auctions on liquidity. It exploits the natural experiment offered by the introduction of a closing call auction on the Australian Stock Exchange on 10 February, 1997. The introduction of the closing call auction is associated with a reduction in trading volume at the close of continuous trading. However, bid ask spreads during continuous trading are largely unaffected by the introduction of the closing call auction. Therefore, closing call auctions consolidate liquidity at a single point in time without having any adverse effect on the cost of trading.

Book Description
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.

Book Description
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.

Book Description
Electronic call auctions are used globally to open and close equity market trading; as such, they are a critically important facility that needs to be better understood. The paper focuses on the impact NASDAQ's calls (introduced in 2004) have had on bid-ask spreads, price volatility, and order routing in the continuous market that follows daily openings and which precedes daily closings. NASDAQ's closing call has significantly reduced both spreads and volatility for all market capitalization groups. Its opening call similarly reduced spreads, while a generally similar, though somewhat weaker, pattern of volatility reduction was realized. Although the pattern of trading volume has, for the most part, not been significantly affected, our findings, comprehensively viewed, suggest that the calls have had a positive spillover effect on the dynamic behavior of price formation in NASDAQ's continuous market.

Book Description
The paper analyses the impact of the suspension of opening and closing call auctions by the National Stock Exchange of India in 1999. We compare volatility, efficiency and liquidity (VEL) of securities before and after suspension, and estimate the value of the auctions using an event study. Following suspension, VEL improved and the CARs were significant but not uniformly positive or negative. We also find that less liquid stocks traded less in the auctions than other securities, especially at the opening, and they experienced the most gains following suspension. This is consistent with there being liquidity externalities associated with auctions, a point previous noted for industrial countries. We conclude that opening and closing call auctions may not necessarily improve share trading in a less liquid emerging market.
