The parameters of the candidate processes at different time scales were estimated and proceed with simulating the empirical distributions of exchange rate returns from selected candidate processes. Results showed that the empirical distribution of returns behaves differently at different frequencies.EnglishContinuous-time processesExchange rate returnsTime scalesComputer simulationRandom processesRisk managementStatistical methodsFinanceArticle10.1016/S0378-4371(02)00986-X1873-2119
