Example: Anika sends money to India
Anika's nephew, who lives in India, is turning 21. As a gift, she wants to contribute £2,000 to his savings. However, the Rupee has recently gone up in price, with £1 being worth 82.0 INR, making her gift amount to 164,000 INR. Believing the Rupee will go back down, Anika places a limit order requesting an exchange rate of GBP/INR = 85.8. This rate is reached 9 days later and 171,600 INR is sent to her nephew's account.
Thanks to the limit order, Anika managed to send an extra 7,600 INR to her nephew.
