The backend is the point
This is a study in backend dataset structure: lookahead-safe queries, multiple-testing correction, and reproducible findings. The frontend stays thin.
full-stack rust · daily bars · rate-limited
Ask a backtest in plain English. Answered in Rust.
Describe a strategy idea the way you would say it out loud. The backend turns it into a disciplined, reproducible study of the eleven SPDR select sectors and the index: how they move, how they move together, and how they react around events.

Run a strategy
Pick a symbol and a strategy. The backtest runs in native Rust over the full daily history, with returns lagged one bar so the result cannot peek at tomorrow.
The universe
The eleven select sectors and the index, on the same daily history the AI Gamma desktop tool uses. Single names are out of scope on purpose: this is about how the sectors move together.

Why this exists
Pure Rust, top to bottom
Leptos on axum, sqlx over Postgres, Qdrant for retrieval, the backtest core compiled native. No interpretation tax on the hot path.
Honest by construction
Daily bars only, hard rate limits, and a backend that refuses a question it cannot answer rather than inventing one.
