@SBF_Alameda BitMEX has ADL (auto-deleveraging) in case they can't liquidate in the book. It does not rule out the possibility that they wanted to prevent an ADL event by going down for maintenance.

The fair value of the contracts is based on SPOT prices, not BitMEX last-traded prices. This prevents positive feedback.
