Over the last few weeks I have shared this functionality with a few friends who also want to keep track of exchange rates and realized that setting these up in the Stocks app is not at all obvious, some would say impossible unless you know the process. Thankfully, once you know the process, it's a piece of cake.
Here are the steps
- Open the Stocks app
- Tap the ( i ) icon in the bottom right hand corner
- Tap the + icon in the top left corner
- Enter the currency rate described as AAABBB=X in the search box (e.g: GBPUSD=X )
- Tap the item in the list
- Click the "Done" button in the top right corner
