Sweeps
Parameter sweeps in progress, queued, and recently completed. Each sweep enumerates 1,000-10,000 combinations of a strategy across historical data with walk-forward validation.
No sweeps yet
The sweep engine (Phase B1 — vectorized backtester) is not yet built. Once it ships, every sweep you fire from a strategy page will appear here with live progress.
What a sweep will report
- Top-N variants by Sharpe / Sortino / Calmar / profit factor
- Walk-forward 70/30 + 5-fold bootstrap (no overfitting)
- Per-regime breakdown (VIX bands, trending vs choppy, event days)
- Indian transaction costs line-itemed (STT, brokerage, GST, slippage)
- Sample-strength badges — 🟢 strong / 🟡 moderate / 🔴 weak
- Liquidity flag when simulated size exceeds historical volume
