Starting 24 August 2020 at 17:00 UTC, new orders submitted to the exchange will result in a single update being generated and published on the WebSocket API order feed containing the final state of that order. Previously an additional intermediate state with ordStatus=New and workingIndicator=0b was also published on the order feed. This change is now live in the Testnet environment.
Please see our blog post for further details.
