Most of people do not know how currency trades are happening in forex. So for example, if you felt the USD would strengthen against the JPY, youd go long or buy the USD/JPY forex pair. Youd also buy if you felt the JPY would weaken against the USD. Alternatively, if you felt the JPY would strengthen against the USD or the USD weaken against the JPY, youd sell or go short USD/JPY. This is how I am doing currency trading with TryMarkets.
