In this article we introduce a decomposition of the joint distribution of price changes of assets recorded trade-by-trade. Our decomposition means that we can model the dynamics of price changes using quite simple and interpretable models which are easily extended in a great number of...

In this paper we introduce a decomposition of the joint distribution of price changes of assets recorded trade--by--trade. Our decomposition means that we can model the dynamics of price changes using quite simple and interpretable models which are easily extended in a great number of...

In this paper we extend Rydberg-Shephard's activity, direction and size decomposition of trade-by-trade price movements to the multivariate case. We illustrate our ideas using a bivariatemodelling problem --- modelling the evolution of the prices of Ford and GM shares. Throughout we use the...

In this chapter we propose using compound Poisson processes to model trade-by-trade financial data. Our main focus will be on developing specific types of Cox processes in order to accurately depict the trading process. We study the problem of signal extracting the intensity of the trading...
