Euronext stock exchange order book and order flow dynamics

Abstract

The purpose of this study is twofold. First we analyze the intraday pattems of the Euronext Stock Exchange order book in terms of relative spread and depth at the best quotes. Then we test if the order flow aggressiveness is predisposed by the current state of the order book. The order book and order flow aggressiveness is analyzed using a data sample with more than 3 million order records across the 4 main national stock market places rnanaged by Euronext. We use the cross section regressions on a set of durnmy variables to analyze the intraday pattems of the order book and the order probit rnodel to study the interaction between the order flow aggressiveness and the current state of the order book. On the contrary to the current literature, the results obtained on the intraday pattems of the order book do not reveal a "U-Shape" but rather suggest that liquidity provision is larger and the relative spread is narrower by the end of the trading session and, thus, transaction costs are srnaller at this moment when compared with the beginning of the day. The trading activity is concentrated at the beginning and by the end of the trading day exhibiting a "waxing moon" shape. The tests held over the order flow aggressiveness given the state of the order book support the idea that traders are more concemed with depth at the sarne side of the book than to the opposite side. We find as well that traders tend to submit less aggressive orders when the transient volatility is smaller avoiding to be picked offby inforrned traders. Therefore, we provide new evidence that order aggressiveness is at least partially explained by the previous state of the order book in particular by the depth on the sarne side of the book and the transient volatility.

Este estudo tem um duplo objectivo, primeiro pretende analisar o comportamento intra­ diário do livro de ofertas em termos de spread e profundidade nos melhores limites do livro de ordens. Segundo, pretende averiguar se a agressividade das ordens, medida através do posicionamento do seu preço face aos melhores preços oferecidos no mercado é explicado pelo estado actual do livro de ordens. No estudo é analisado o livro central de ofertas e a dinâmica das ordens introduzidas nas 4 praças nacionais da Euronext através de uma base de dados com mais de 3 milhões de ofertas introduzidas no sistema. Ao contrário da literatura recente sobre esta matéria não se encontrou evidencia de que o spread e a profundidade do livro de ordens tem um formato em U mas sim que a oferta de liquidez é maior e o spread relativo é mais estreito no final da sessão de negociação e, como tal, os custos de transacção são menores neste momento. A negociação está concentrada no início e no final da sessão exibindo um formato semelhante a uma "lua em quarto crescente". Os testes realizados sobre a agressividade das ordens sugerem que os investidores monitorizam o estado da profundidade do mercado. Contudo, preocupam-se mais com a profundidade do livro de ordens no mesmo lado da oferta do que com o lado oposto. Encontramos também evidência de que os investidores tendem a ser menos agressivos quando a volatilidade de curto prazo é maior evitando assim a negociação contra investidores mais informados. Conclui-se portanto que a agressividade das ordens é em parte explicada pelo estado actual do livro de ordens, particularmente pela profundidade do mercado na mesma ponta e pela volatilidade de curto prazo.
