Overview
What Is Bro | Quant
A deterministic trading engine and the platform around it: one fact semantics across different execution environments.
English localization is preserved as a draft. It uses the same claim IDs and status model as the Russian source, but remains noindex until editorial review.
Bro | Quant is built around one rule: the same state, configuration and ordered accepted facts must produce the same next state. The environment may change; the meaning of facts inside the core must not.
Strategy decides, Execution turns the decision into action, and Portfolio records what happened to capital. Today this loop is proven only in a bounded test-only BACKTEST environment. DRYRUN and LIVE are not yet claimed as ready for the new engine line.
The platform now receives verified historical observations from the calculation owner. Labs is available for research; trading launch is not yet open.
Why Determinism Matters
The goal is not to make historical testing and real trading accidentally show the same result. The goal is to preserve strategy and capital-accounting meaning as the environment changes.
Three Roles
- Strategy decides what to do from accepted state.
- Execution performs the decision in the selected environment.
- Portfolio records capital, positions, execution facts and results.
The User Path
- Understand the principle and current boundary on Home.
- Explore saved research scenarios in Labs.
- Complete access and build a personal configuration in Dashboard.
- Confirm an action separately when the required contour is actually available.
Current Boundary
- The new deterministic line is proven only in a test-only BACKTEST composition.
- DRYRUN and LIVE remain separate future verification stages.
- The operating private v4.4.4 contour is a separate legacy lineage and does not prove live authority for the new architecture.
- When evidence is insufficient, the system must preserve UNKNOWN instead of inventing a convenient value.
