What is the mid-market rate?
The mid-market rate is what your money’s actually worth on the global market compared to another currency. It’s the midpoint between worldwide supply and demand for that currency — and the rate banks and transfer services use when they trade among themselves. Use this rate as a baseline to compare against the rates provided by your bank or transfer service. With it, you’ll discover which companies offer the best rates.

I plan to go spend some very long periods in Buenos Aires, and see the exchange rate is currently good. What are my options about forward buying or locking in right now ? And if so, how ?
Hi U.K. resident,
Thanks for getting in touch with finder. I hope all is well with you. :)
As what our guide mentioned, there are a few tools that you might want to try. These are the Contract Options (Spot Contracts and Forward Contracts) and Order Options (Limit Orders and Stop-Loss Order). Please refer to our guide to know more about these tools.
Once you have already decided which tools to use, you can then read more about them.
I hope this helps. Should you have further questions, please don’t hesitate to reach us out again.
Have a wonderful day!
Cheers,
Joshua
