Company A buys a call option in sterling. When the exchange rate in the maturity market is higher than the agreed price, Company A can exercise the option to make up for the exchange rate fluctuation loss in the spot market. Otherwise, give up the option. The breakeven point of this option is:1.5000+750/25000 =1.5300. That is to say, when the market exchange rate is greater than 1.500, the exercise of options is greater than 1.5 and less than 1.53, and the loss is equal to 1.53, which is the equilibrium point, and greater than 1.53. When it is less than or equal to 1.5, the option is not executed, and the loss fee is the option fee.

When selling the pound put option, exercise it when the market exchange rate is lower than the agreed exchange rate, and the breakeven point is 1.47.
