That's pretty cool to see, and can be quite helpful. I do get some comments from left field from time to time, and always check those before up-voting, but something like this would make it a lot easier to see it at first glance.
One question - how does it react to incoming Hive? Let's say I buy 500 Hive on Binance, transfer them to my account here, and then withdraw only 400 to HE. Would it turn negative then? Mine is probably in the mega-red right now, as I just put some 50$ into SPL that way :-D
