This paper analyses the impact of a minimum price variation (tick) and time priority on the quote dynamics and on trading costs when competition for the order flow is dynamic. It finds that convergence to competitive prices can take time and that the speed of convergence is influenced by the...

We analyze the impact of a minimum price variation (tick) and time priority on the dynamics of quotes and the trading costs when competition for the order flow is dynamic. We find that convergence to competitive outcomes can take time and that the speed of convergence is influenced by the tick...
