Capturing Order Book Dynamics in the Interbank EUR/PLN Spot Market

In this paper, I examine order submissions and cancellations in the Reuters Dealing 3000 Spot Matching System, the main order-driven market for interbank trading of the euro/złoty (EUR/PLN) currency pair. I generalize the asymmetric autoregressive conditional duration (AACD) model of Bauwens and Giot (2003) with respect to more than two competing risks. With the new multistate AACD model, I examine the timing of different order submissions and cancellations that take place on different sides of the market and vary according to their level of aggressiveness. I investigate different liquidity or information-oriented factors that exert an influence on the dynamics of the limit order book.
