FULL TITLE: Modelling and measuring slippage using the signature of order book data

ABSTRACT:

We aim to explore how multiple features observed in real market data can be characterised quantitatively via a property of sample paths known as the signature of the path.

At an abstract mathematical level, the notion of a signature as an informative transform of a multidimensional time series was established by Ben Hambly and Terry Lyons [1], meanwhile Ni Hao et al [2] have introduced the possibility of its use to understand financial data and pointed to the power this approach has for machine learning and prediction.

We evaluate and refine these theoretical suggestions against some real world data and practical examples. Moreover, the paper identifies a low dimensional part of the signature that preserves essential information for understanding and measuring various market features in order to improve the efficient choice of trade execution algorithms.
