One thing to understand, though, is that the price feed is the price of HIVE, not HBD.

That's kind of what I thought, but not what I was getting in that Discord conversation.

So, the only thing we can really do on-chain (side-chain) is to get CMC/CG to take in the LP price?

I'd be perfectly happy to include DEX prices in my feed if there is a simple API I can use to get those prices.

If there isn't such a thing, it seems like something that would be great to have, eh @aggroed?
