Alex Papanicolaou: Background Subtraction for Pattern Recognition in High Frequency Financial Data

August 31, 2016 @ 4:00 pm - 5:00 pm

This event is part of a series of Neyman seminars offered through the Statistics Department.

Abstract: Financial markets produce massive amounts of complex data from multiple agents, and analyzing these data is important for building an understanding of markets, their formation, and the influence of different trading strategies. We utilize a signal processing approach to deal with these complexities by applying background subtraction methods to high frequency financial data to extract significant market making behavior. In foreign exchange, for prices in a single currency pair from many sources, we model the market as a low-rank structure with an additive sparse component representing transient market making behavior. We consider case studies with real market data for how the model reveals pricing reactions that deviate from prevailing patterns and discuss the broader implications for financial markets as it relates to algorithmic trading and risk.
