Forty Years, Thirty Currencies and 21,000 Trading Rules: A Large-Scale Data-Snooping Robust Analysis of Technical Trading in the Foreign Exchange Market

Working Paper: CEPR ID: DP10018

Authors: Pohsuan Hsu; Mark P. Taylor

Abstract: We carry out a large-scale investigation of technical trading rules in the foreign exchange market, using daily data over a maximum of forty years for thirty developed and emerging market currencies. Employing a stepwise test to safeguard against data-snooping bias and examining over 21,000 technical trading rules, we find evidence of substantial predictability in both developed and emerging markets, measured against a variety of returns and risk-adjusted performance metrics. We present time-series and cross-sectional variation in sub-periods and cultural and/or geographic groups, respectively, suggesting that temporarily not-fully-rational behavior and market immaturity lead to technical predictability and potential profitability.
