First and foremost, I would like to say thank you to Dr. Reinoud Joosten. Thank you for giving me the opportunity to graduate under your supervision and letting me work on the topic of High Frequency Trading. Thank you also for the insightful discussions and useful feedback which have definitely contributed to making this thesis a comprehensive study. I would also like to thank Dr. Berend Roorda for being by co-supervisor and Abhishta Abhishta for providing me valuable feedback to my thesis. To my friends, Eline, Ruud and Thomas I am thankful for the many pleasant meetings, trips and dinner parties that we have had and hopefully we will still have for a long time to come. You guys are the best. I would like to say thank you to my parents, for always giving me the right example of how to be a good person, motivating and encouraging me in every situation. Also thank you very much for the many packages with Polish treats making sure that I always have a little bit of home with myself. I would like to thank my boyfriend Ivan for being always there when I need it, making me laugh and being my groupie. I have never met a person so similar to me with so many opposite qualities, but I guess that this is the magic recipe that is needed to make things work. 4 Table of Contents Abbreviations and symbols ........................................................................................................................... 2 Acknowledgements ....................................................................................................................................... 4 1.
