How to use Trading System Blueprinter
Pick your data source, LLM, broker, storage, risk engine, and logger. The page emits a Mermaid architecture diagram, a starter repo scaffold (downloadable ZIP), and a list of decisions and risk gates so you don't ship a half-thought stack.
What It Does
Use the calculator with intent
Pick your data source, LLM, broker, storage, risk engine, and logger. The page emits a Mermaid architecture diagram, a starter repo scaffold (downloadable ZIP), and a list of decisions and risk gates so you don't ship a half-thought stack.
Engineers starting a new trading system who want to surface the architectural decisions and risk gates before they write the first line of code.
Interpreting Results
The Mermaid diagram is the discussion artefact. The checklist below it is the gating list — every checkbox is a decision that needs a written answer before the system goes live.
Input Steps
Field by field
- 1
Pick option
Pick scope (retail / single-strategy production / multi-strategy fund). The blueprint scales with scope.
- 2
Pick option
Pick asset class and frequency. Equity / daily looks different from FX / minute looks different from crypto / tick.
- 3
Read outputs
Read the architecture diagram and component spec. Each component lists technology recommendations and known failure modes.
- 4
Download
Download starter templates: docker-compose, Terraform IaC, monitoring dashboards. They're skeletons — production hardening is your responsibility.
- 5
Reference
Reference the compliance section. Even retail strategies need basic recordkeeping; institutional needs more.

Risk gate count multiplies (pre-trade checks, position limits, kill-switch). Treat each as a non-negotiable PR before go-live.
