To any transaction on the „enter coins page“ you can add a „trade group“. It is just an additional sorting /grouping option for some reports we offer.

You can change / add a trade group of more then one trade via the „bulk edit / delete“ option on the „enter coins page“. 

Here you can choose which trades - sorted by exchanges, trade groups, dates etc - should be adjusted.

You can sort the "Balance by Exchange page" in the drop down for trade groups as well.
