I'm keen on understanding if this is displayed wrong in the GUI.
How did you get to these numbers and did you account for the "Target collateral ratio"?
Armin, you missed one possible scenario I think.
4) A position updated their target collateral ratio, removing some of the required sell to reach collateral ratio.
Say that one position doesn't have a target at all, then the whole position will be put to market (as long as they are under MCR I believe). If a position has a target on the other hand, it will only put so much on the market that is required to reach MCR ratio.
Please tell me if I'm wrong, but that's how I understood it to work.
