Chapter NineFutures and Options on Foreign Exchange
Example: On Monday morning you take a long position in SF futures contract that matures on Wednesday afternoon at $0.75/SF.
1. At the close of trading on Monday the futures price has risen to $0.755. Because of the daily settlement you receive a cash profit of
$625 =125,000 x (0.755-0.75)
2. At Tuesday close the price has declined to $0.743. You must pay the $1500 loss (125,000 x [0.743-0.755]) to the other side of the contract.
3. At Wednesday close, the price drops to $0.74, and the contract matures. You pay $375 loss to the other side and take the delivery of the SF, paying the prevailing price of $0.74. You have a net loss on the contract of $1250 (625-1500-375)
You can also close out your long position with an offsetting trade, if you don’t want the delivery of the SF.

The change was .01 percent of $1 million representing $100 on an annual basis. Since it is a 3-month contract one basis point corresponds to a $25 price change.
The exercise price (E), also known as strike price, equals the spot price (S) of the underlying asset.
The exercise price (E) is less than the spot price (S) of the underlying asset.
The exercise price is more than the spot price of the underlying asset.

Exercise of a currency futures option results in a long futures position for the holder of a call or the writer of a put.
