As part of the ongoing enhancements to our infrastructure and networks underpinning our API services, BitMEX is introducing a new websocket endpoint, ws.bitmex.com/realtime (ws.testnet.bitmex.com/realtime for Testnet), which is to become the recommended domain to subscribe to any BitMEX feeds. 

The websocket feeds behave the same in both domains and at this time we do not expect any breaking changes on the schema, data, and commands. Users are advised to start directing their websocket clients from the existing endpoint to the new one at their earliest convenience.

The existing endpoint, www.bitmex.com/realtime (testnet.bitmex.com/realtime for Testnet), will remain in service for approximately 3 months from now. However, note that by using it, you may experience an increase in latency and in the frequency of disconnections from 1st November 2021. 

A further announcement will be made prior to retiring the existing websocket endpoint.

To further reconcile contract naming conventions on BitMEX, we will list four new AXSUSD, EOSUSD, LINKUSD, and SOLUSD Perpetual Swaps on 20 October 2021 at 04:00 UTC and conduct early settlement of the current AXSUSDT, EOSUSDT, LINKUSDT, SOLUSDT, AAVEUSDT, MATICUSDT, SRMUSDT, SUSHIUSDT, TRXUSDT, UNIUSDT, VETUSDT, and XLMUSDT perps on 2 November 2021 at 12:00 UTC. Early settlement will occur on Testnet 24 hours earlier than the mainnet so users can see how the delisting process works.

The new AXSUSD, EOSUSD, LINKUSD, and SOLUSD perps will have 0 Taker and 0 Maker Fees until 2 November 2021 at 12:00 UTC. 

They will be visible on the platform from 04:00 UTC on 19 October 2021 as Unlisted, 24 hours before start of trading. 

Stay tuned to our blog for more details coming soon.
