One Trading runs a regulated 24/7 futures exchange on QuestDB

One Trading, a regulated European derivatives exchange, operates under MiFID II and MiCAR, offering round-the-clock trading for crypto and equity markets with sophisticated margining solutions. They became the first to introduce 24/7 central limit order book trading for equity futures, supported by a robust matching engine capable of processing 1.8 million orders per second with sub-200 microsecond latency, thanks to collaboration with AWS on cloud-native colocation. Facing increasing trading volumes, One Trading transitioned from using Amazon DynamoDB and RDS to QuestDB, a high-performance database that allows real-time querying and efficient ingestion of over 5 million rows per second. QuestDB's infrastructure includes a distributed architecture with multi-AZ deployment and automatic failover, ensuring 99.9% uptime and seamless scalability. By self-hosting QuestDB Enterprise, One Trading achieved predictable costs and data sovereignty, enhancing their ability to scale and innovate without vendor lock-in. They acknowledged trade-offs such as incomplete AWS deployment documentation and evolving indexing, which were addressed with direct support from QuestDB's engineering team.
