Welcome to our annual survey of European trading volumes and market fragmentation at the end of yet another highly eventful year of trading. We aim to provide a brief overview of the key trends and patterns in the market microstructure in 2022 by comparison with the previous five years. The survey is based on a vast amount of data. Since the beginning of the new MiFID2 regime in Europe, we have collected over 2.5 trillion data points from the European equity markets. Back in Q1 2020 it felt like we were watching a truly exceptional event but despite lower volatility, the markets managed to deliver something even more unpredictable. Please have a read of our latest European market microstructure and let us know your thoughts or ideas for any further investigations.
