Thanks for the support, yes I'm definitely planning on getting a bot built for trading on Hive.
That should cover most of the price tracking stuff too, so all I'd need to do is add some sort of notification service to it and it would take care of the other thing as well.
It's definitely possible but there's also a million other bots competing with you on bigger exchanges. And fees/delays on Coinbase make that not really feasible.
The NFT thing is a bit easier because worst case, you don't get the NFT you want. With arbing on exchanges, worst case is you buy coins and get stuck with them because another bot frontran you.
