I need a lot of Euros because I frequently travel to European countries. Therefore, I always have an amount of Euros at home and from time to time I exchange a large amount of Euro. To save some money, I try to observe the exchange rate and try to get a favorable one. Doing this manually is a little bit tedious and therefore I'm looking for a tool that does this for me. The tool should be able to observe a specific exchange rate and inform me via email if a certain rate is achieved or if trend/forecast show that a minimum is reached.
Is there any tool like this available? I'm interested in a generic solution, but for now a tool for CHF - EUR and CHF - USD would also be okay.
