LGTM, I am a bit curious about how we can handle the fact that there's a variable part that could be unexpectedly large for the funding payments.

Also, when we close one market, how are the conditions for the next market selected?

We have this issue for settlement and also normal behavior of the market. I think the clamp is helping us a lot in this since closing a market might have a lot to do with index/mark price divergence
