This thesis is dedicated to the study of market microstructure and price dynamics in the electronic market. We start byconstructing an order flows model under the framework of point processes. We combine multivariate Hawkes processeswith the so-called “queue reactive" property firstly introduced in [87]. In our model, the intensity of order flows dependsexplicitly on the current state of the Limit Order Book and also on past order flows. Ergodicity is proven in this model,which allows one to apply it for simulation purposes. The second part is dedicated to the analysis of rough volatility. Fromthe Gaussian random field, we construct a family of parametrized random processes. Our approach unifies two famousvolatility models, the rough fracti...
