In Shrimpy, it's possible to provide a custom name for your exchange accounts. That way you can differentiate between exchange accounts when you have a number of different accounts linked for the same exchange. This is done simply by going to "Settings", "Exchange", then selecting the exchange you would like to rename. At the top, you will see an edit icon that can be used to rename the exchange account.
The maximum character count for a name is 15 characters. If you remove all of the characters in the name field, it will default to the name of the exchange.
