We will temporarily halt trading in our Testnet environment on Thursday, 15 July at 02:15 UTC to facilitate a major upgrade to our operating system. On Thursday, 29 July at 02:15 UTC, we will temporarily halt trading in our production (Mainnet) environment for the same upgrade.
From this time in each instance, any order actions will be rejected. Deposits made will be queued for processing.
In both instances, the system will be online again in cancel-only mode from approximately 03:10 UTC. Order cancel requests and deposits will be processed normally. Continuous trading will recommence from approximately 03:15 UTC.
From the halt of trading until continuous trading resumes, there will be no Mark Price updates and hence no liquidations.
