Strategy Lifecycle
Author and backtest strategies with real spread & slippage, capacity and over-fit scoring, and your own paper track record — draft-only and gated by default.
A disciplined, honest path for every strategy.
BYP treats strategies like experiments: authored, tested against history with real trading frictions, scored for over-fitting and capacity, and certified with reproducible evidence — never auto-deployed to live money.

Build a strategy with clear rules and assumptions.
Backtest with real frictions
Spread and slippage are modelled by default — no filling at the mid for free. A loud banner flags simulated price series so a backtest is never mistaken for a live edge.
Capacity & over-fit scoring
See the $-size where execution cost eats the edge, an over-fit score from walk-forward + Monte-Carlo, and side-by-side comparison of pinned runs.
Your track record
Every paper run aggregates into one honest scorecard — best return and deepest drawdown surfaced equally. Live execution stays gated and approval-based.
