OKEx Maintains Order in the Futures Market by Injecting 2500 BTC


This is regarding the forced liquidation incident on July 31st 2018 when an large long position in BTC0928 futures contract was liquidated by force at 20:17:14 July 31, 2018 (Hong Kong Time, UTC+8). It was a huge order and this triggered their risk management system and alerted insurance fund team.

The client with user ID 2051247 initiated an unusually large long position order (4168515 contracts) at 2am on July 31 (HKT) and triggered our risk management alert system.

In this case, the insurance fund cannot cover the total margin call losses and due to this a full account clawback occurred.

Only users who have a net profit across all three contracts for that week will be subject to the clawback. OkEx will take a portion of the profit in equal percentage from all profited traders only to cover the difference between the liquidated price and settled price.

To reduce the market risks induced by this incident, the following actions were be executed:

– OKex injected 2,500 BTC to bring clawback for the period to 17% (would have been up to 40% otherwise).

– Resulting rebased position from $8020 to $7483 got gobbled up by market within first 3 minutes of post-settlement trading.
