Yes, I still use it, but the google spreadsheets API keeps getting rate limited, so it hasn't been working super well lately. I've been emailing with the developer of the API to see when they might get token-based requests working.
I don't have options to do exchange specific rating. Feel free to add it yourself in your own copy though.
"ID cost of trades"? Not sure what you mean about that. You mean the exchange fees? Yeah, that might be helpful, but it gets confusing to track with some exchanges, so I didn't want to bother with those details (though in previous spreadsheets, I have).
Again, not too interested in arbitrage opportunities via this spreadsheet. I think there are better tools out there for that like Cryptopia.
