Deep learning for limit order books [PDF]
Quantitative Finance, 2018 This paper develops a new neural network architecture for modeling spatial distributions (i.e., distributions on R^d) which is computationally efficient and specifically designed to take advantage of the spatial structure of limit order books. The new architecture yields a low-dimensional model of price movements deep into the limit order book ...

The Impact of Hidden Liquidity in Limit Order Books [PDF]
SSRN Electronic Journal, 2009 We show that the order submission strategies of liquidity demanders and suppliers change when the observed price dynamics signal that the order book is likely to contain hidden liquidity. We combine the signals of hidden liquidity that can be extracted from the price dynamics with the actual data on hidden liquidity to differentiate between situations ...

LiT: limit order book transformer [PDF]
Frontiers in Artificial IntelligenceWhile the transformer architecture has demonstrated strong success in natural language processing and computer vision, its application to limit order book forecasting, particularly in capturing spatial and temporal dependencies, remains limited. In this work, we introduce Limit Order Book Transformer (LiT), a novel deep learning architecture for ...

A limit order book model for latency arbitrage [PDF]
Mathematics and Financial Economics, 2011 We consider a single security market based on a limit order book and two investors, with different speeds of trade execution. If the fast investor can front-run the slower investor, we show that this allows the fast trader to obtain risk free profits, but that these profits cannot be scaled.
