Its not possible to set accurate exchange rate
Currently it's not possible to set currency exchange rate more accurate than 5 decimals. Unfortunately it applies to both sides.
For example my currency is HUF I want to exchange to EUR.
The exchange rate is for EUR/HUF is 384.76269 but the HUF/EUR is 0.0026. It's not letting me to change the EUR/HUF exchange rate to for example 360.00000. When I do that it automatically calculates HUF/EUR which is 0.002777777777777777... and because the limit is 5 decimals it says okay bro you get 0.00278 and be happy with it. But that's 359.71223 in EUR/HUF and it applies for it as well. This is messed up. I think the user should be allowed to chose which exchange rate the user want's to use, EUR/HUF or HUF/EUR in my case.
