**NEW LOGO FOR THE BACHELIER FINANCE SOCIETY**

As announced during the last BFS World Congress in New York, the society has a new logo. In the meantime, this has been integrated into the BFS website.

The use of the infinity symbol depicts the concept of limitless, borderless and complex thinking. Its cyclicality shows a constant state of re-thinking and re-creating. By supporting and positioning the infinity symbol diagonally, it highlights the initial b emerging from a complex concept, like revealing a hidden pattern.

### MOOCs in Mathematical Finance

Massive Online Open Courses (MOOCs) are a relatively new method for teaching and disseminating knowledge. The Bachelier Finance Society has started listing MOOCs related to mathematical finance on its webpage, see http://www.bachelierfinance.org/publications/moocs.html. Members are encouraged to send their MOOCs to the Administrative Director (office@bachelierfinance.org) or the Editors of the Newsletter if they want them included in this list.

We have also conducted a short Q&A with two colleagues who have recently created MOOCs related to mathematical finance, Jakša Cvitanić (JC) and Damir Filipović (DF), on the pros and cons of MOOCs.

#### Q&A on MOOCs

*What is your MOOC about?*

**JC:**The MOOC starts with discrete-time, binomial trees models, and then goes to continuous-time, Brownian Motion driven models. A basic introduction to Stochastic Calculus is given. The Black-Scholes-Merton pricing model is introduced, as well a stochastic volatility models, and interest rate models. Both the Partial Differential Equations approach, and the probabilistic, martingale approach are studied.

**My MOOC gives an introduction to interest rates and related contracts.**

**DF:**** **

*Who should follow your MOOC?*

**JC:**Students and practitioners interested in the mathematical basis of option pricing, with a good background in calculus and probability.

**The course is primarily aimed at advanced graduates interested in quantitative finance, along with finance professionals with an interest in interest rate models. I also recommend the MOOC to our Master students in financial engineering in parallel to the course I teach in class.**

**DF:**** **

*How is your MOOC different from analogous courses on option pricing you have taught at Universities?*

**JC:**It is not much different. The main difference is the additional MOOC features such as the discussion forum, and the ability to watch lecture videos at your own pace.

**DF:**The MOOC is more concise than analogous courses that I taught in class at various universities. I have completely revised the previous course material that was based on my textbook titled Term-Structure Models. The MOOC consists of many practice quizzes that offer the students the possibility to check and review the course matter in small steps, roughly after each section. As a consequence I have added a lot of new exercises to my existing course material.

** **

*What are the advantages and disadvantages of MOOCs compared to ordinary courses at Universities?*

**JC:**The main advantage is the above mentioned discussion forum, and the ability to watch lecture videos at your own pace. The disadvantage is no direct communication with the instructor. The best learning experience is the flipped classroom approach: having the students in an ordinary course use the MOOC to watch the lectures online, and then work on problem solving and case presentations in the class.

**DF:**The MOOC allows for flipping the class room. This means, I give as reading assignments parts of the MOOC, so that students come prepared to class and I can focus on problem solving during class hours. The didactic philosophy behind this is that class hours are too precious to be filled with me writing definitions on the black board. The students shall learn new subject matter at first on their own, so that we can revisit it in class and have more in-depth interaction and students get feedback on their own learning process.

** **

*How was the experience of preparing a MOOC? Would you recommend that people prepare one?*

**JC:**It comes with a high fixed cost - a lot of time investment is required to develop and record it. It is much less time consuming in the future years.

**DF:**It takes a substantial amount of time and energy. But this is a one-off that pays off. It helps yourself to revisit and structure your course material, set learning targets, and develop a lot of quizzes and exercise questions.

** **

*Do you think that MOOCs and video-archived lectures are the future of education, and professors will become obsolete soon?*

**JC:**It may be the future for introductory courses, but not for more specialized courses. Also, even in those professors will still be needed, especially in higher ranked universities, to provide guidance and interaction to students.

**DF:**MOOCs and other forms of digital education will become much more common in the future. MOOCs are the new textbooks. They give millions of people free access to state of the art education. Professors will not become obsolete but our teaching form and styles will have to adapt to digital education.

### BOOK REVIEW

## Algorithmic and High-Frequency Trading

### by Álvaro Cartea, Sebastian Jaimungal and José Penalva

### Mathieu Rosenbaum, École Polytechnique

As the head of a masters program in quantitative finance, I am often asked the following question by students: what is a good textbook on the mathematics of trading algorithms?

I must say that I was never able to provide a really satisfactory answer. Thanks to Álvaro, Sebastian and José, now I can and I really thank them for that.

The book *Algorithmic and High-Frequency Trading* is published at a time where I believe the different aspects of market microstructure are quite well understood. However, probably no reference was properly summarizing the mathematics related to the design of trading algorithms. This book fills this gap and it was much needed. So I am convinced it will become a standard textbook very rapidly.

Beyond students, this work will also be very useful for academics looking for an overview of the mathematics of high frequency trading and for practitioners, who will find elements to build trading strategies and probably theoretical foundations for algorithms that they are already using.

The first part of the book is very accessible. It provides a summary of the basic elements of market microstructure: the way markets are operating in practice, a typology of market participants, a description of the main variables of interest and the most classical theoretical models. This part represents to me an excellent crash course on market microstructure.

Then the authors specialize on one particular topic of market microstructure: (optimal) algorithmic trading. To do so, they first need to introduce some mathematical concepts. This part (Part 2) is quite a *tour de force*. Indeed, in a few pages, the authors are able to explain the main ideas of stochastic control and optimal stopping. After reading this, one has already a sufficient knowledge of the technical concepts to deal with the sophisticated optimization problems occurring in practice. Of course one may say that the presentation is not completely rigorous. However, given the wide targeted audience for this book, this is in my opinion the right way to introduce such mathematical tools.

Equipped with the material of Part 2, the reader can now consider optimal trading problems which are relevant in practice. Starting from the classical setting of optimal execution, the authors describe in Part 3 a series of algorithmic trading problems and their solutions to them. In various contexts, they are able to answer the following high frequency related questions: When should I act on the market? Which type of orders should I use? What are the informative indicators? On which platform should I trade? As a market maker, what would be a good strategy for me? Of course no practitioner would probably directly apply the results here in her/his actual trading. However, such results should be seen as the theoretical foundations of the algorithms used in practice. What I find particularly amazing in this part is that the authors manage to never use cumbersome computations but still provide the main mathematical elements. Actually the reader gets the very pleasant feeling that all this is quite easy and that she/he would be able to use this machinery in many other situations. Another nice thing is the fact that this part also contains exercises.

Thus this book is very well balanced between market description, data analysis, theoretical mathematics, models and case studies. It focuses on the design of trading algorithms, which is nowadays a standard problem for many market participants. The writing and presentation are excellent. It should definitely be on the shelf of anybody interested in quantitative microstructure.
