[//]:content-type-MARKDOWN-DONOT-DELETE Gate.io is going to upgrade and optimize the spot trading engine from 14:10 – 14:20 UTC on 22 Feb, 2023. The upgrade will take about 10 minutes and partial service of spot trading will be unavailable during the process. We expect there will be trading interruption (less than 1 second) and query interruption (less than 1 second). If you are an affected trader and API user, please adjust your strategies beforehand. Affected services: All spot trading pairs This upgrade will prepare the spot engine for porting to the portfolio margin account, as part of our effort to deliver better trading service to our users.
