This document discusses currency options. It defines a currency option as a financial derivative that gives the buyer the right to buy or sell a currency at a specified exchange rate during a specified period of time. There are two types of currency options: put options, which give the right to sell one currency and receive another, and call options, which give the right to buy one currency with another. Currency options provide advantages like limiting risk to the premium paid and allowing profits from favorable exchange rate movements, but they also have disadvantages like losing the full premium if the option expires out of the money or is terminated early.
