We propose several nonparametric predictors of the mid-price in a limit order book, based on different features constructed from the order book data observed contemporaneously and in the recent past. We evaluate our predictors in the context of an order execution task by constructing order...

The unique characteristics of Chinese stock markets give rise to the difficulty of assuming innovation distributions and the specification form of the volatility process when modelling volatility with the parametric GARCH family models. This paper examines the Chinese stock market volatility and...

We propose a new methodology based on Fourier analysis to estimate the fourth power of the volatility function (spot quarticity) and, as a byproduct, the integrated function. We prove the consistency of the proposed estimator of the integrated quarticity. Further, we analyse its efficiency in...
