USD/JPY

USD/JPY

In this example the US dollar is the base currency and thus the "basis" for the buy/sell. If you think that the Japanese government is going to weaken the yen in order to help its export industry, you would execute a BUY USD/JPY order. By doing so you have bought U.S dollars in the expectation that they will appreciate versus the Japanese yen. If you believe that Japanese investors are pulling money out of U.S. financial markets and repatriating funds back to Japan, and this will hurt the US dollar, you would execute a SELL USD/JPY order. By doing so you have sold U.S dollars in the expectation that they will depreciate against the Japanese yen.
