The persistence of both trend and value effects at varying timescales presents complex challenges for understanding and predicting the behaviour of prices in limit order books. A further level of challenge has become increasingly apparent as markets have witnessed significantly greater numbers of spikes in prices, traded volumes and volatility, particularly during the current pandemic. Given the recent gyrations in global financial markets, predicting the timing, amplitude and duration of spikes has not received the attention that would appear to be warranted. This talk presents a novel approach to modelling spikes and explores how such a model sits naturally in an agent-based approach in order to gain greater insight into financial market behaviour.
