We implement the arbitrage strategies, Pair trading in the foreign exchange markets. Utilizing daily data from Jan. 2000 to Apr. 2014, our strategies generate Sharp ratios as high as 0.22. Based on the market neutrality and hedging characteristic in long-short investment, we provide the profitability analysis using four different approaches after considering transaction costs. These approaches consist of match with minimum distance between two normalized prices Distance); estimation of long-term equilibrium and model the resulting residuals (Cointegration); linear and Non-linear relationship between two potential assets (Correlation and Copula). With the result of CAPM test, positive and significant alpha represent our trading strategies is profitable during our sample period. The sources of excess returns reflect difference of liquidity, price pressure while executing trading and the compensation of violation in “Law of One Price"
