The results are derived from a comprehensive order flow dataset distinguishing between different groups of market participants and covering a broad cross-section of currency pairs. Our findings show that both the contemporary and permanent price impact are heterogeneous across agents, time, and currency pairs, supporting the asymmetric information theory. A trading strategy based on the permanent price impact capturing superior information generates high returns even after accounting for risk, transaction costs, and other common risk factors documented in the FX literature.enCarry tradeCurrency portfoliosHeterogeneityOrder flowPrice discoveryconference paper
