How it works
From first call to live execution, in three structured stages. Every engagement follows the same disciplined process. Each stage takes at least one week, so the logic is clear before any code is written.
- Strategy audit Minimum 1 weekWe review your strategy as it stands: entry and exit rules, position sizing, risk limits, and the market conditions it is built for. We test the performance data for consistency and flag the discretionary steps that can be turned into rules. The result is a written specification of exactly what the software must do.
- Complexity and workload estimation Minimum 1 weekWe map the specification to your platforms, brokers and data feeds. We assess the technical complexity, the integration points, the latency requirements and the edge cases. You receive a fixed scope, a development timeline and a quote, before any build begins.
- Development and testing Minimum 1 week, scaled to scopeWe build the engine or script to the agreed specification. It is then tested in simulation and paper trading, and under live-market conditions with limited size. We deliver the finished software with documentation and handover, and support the first live sessions.
Most projects take three weeks or more from audit to delivery, depending on complexity.
