Trading technology
Granittor designs, builds and operates its own trading infrastructure: market connectivity, algorithms and risk control. An architecture that is proprietary end to end, with no third-party dependencies in the critical path.
Granittor was founded to bring structural discipline to trading technology.
We do not chase volatility.
We build systems that endure.
Strength is not aggressive.
Strength is permanent.
In an industry dominated by noise, we work with conviction. We build concentrated, research-driven technology, designed to hold up across complete market cycles.
Services
We develop and maintain every layer of the architecture, from market data ingestion through to risk control. That integration is what keeps a single standard across the whole system and allows us to respond quickly when conditions change.
Infrastructure developed in house: market connectivity, risk control and observability.
Maintenance, updates and technical assistance provided on a subscription basis, with agreed response times for as long as the systems are in production.
Design, validation and production rollout of algorithmic strategies, with defined risk limits and prior testing against historical series.
How we work
Four phases and one rule that is not up for negotiation: nothing reaches production without being validated first.
We assess the starting position and the objectives set out. The scope of the work comes from that assessment, not from a fixed catalogue.
The solution and its risk limits are defined, then tested against historical data before going anywhere near production.
Gradual rollout, with caps and parameters reviewable at every phase. If a metric moves out of range, it stops and is corrected.
From that point the operation is ours. Systems remain under continuous supervision and are reported on periodically.
