WebSocket API Feed Interruption, 24 July 2019

Between 10:44:13 and 10:52:29 UTC on 24 July 2019, the realtime data on the following websocket API feeds was interrupted:

  • account, affiliate, execution, funds, instrument, margin, order, position, trade, transact, wallet

Users of the BitMEX website may have noticed that some data was not updating during this period; e.g. in the Recent Trades panel, Open Orders panel, Fills panel, and Position panel.

The following public feeds were unaffected during this period:

  • funding, insurance, liquidation, settlement, impactQuote, impactQuoteBin1m, quote, quoteBin1m, quoteBin5m, quoteBin1h, quoteBin1d, tradeBin1m, tradeBin5m, tradeBin1h, tradeBin1d, orderBookL2_25, orderBook10, orderBookL2

The REST API was also unaffected and client-side data loss due to missed feed updates during this period can be resolved using the REST API.

During this period we continued to process all order instructions and the trading engine was unaffected. The outage was due to a slow consuming internal market data service which became degraded, putting pressure on our market data infrastructure. This internal market data service has been suspended whilst the root cause is being investigated. Additionally, several safety mechanisms are currently being deployed to prevent a potential recurrence from impacting user-facing feeds.

We apologise for any inconvenience this interruption may have caused. If you have any further questions please contact Support via our contact form: https://www.bitmex.com/app/support/contact.

Notice Regarding COIN Prediction Futures

The SEC decision regarding the Bats exchange rule change is due by 11 March 2017. This decision, if positive, will allow the COIN ETF to list. Because this is a Saturday, there is a possibility that no public announcement will be made until Monday 13 March 2017.

The COIN Prediction Futures contract, COIN_BH17, will now settle on Tuesday 14 March 2017 at 00:00 UTC. If a public announcement regarding the rule change is made by the SEC prior to the settlement date, BitMEX will settle the contract early pursuant to the payout guidelines.
