Hammer / Pin Bar — Base Pattern
Strong intraday rejection of lower prices. Sellers pushed the price down far but buyers took control back before close.
✅ Lower wick ≥ 2× body (configurable in optimizer)
✅ Upper wick ≤ 25% of body (configurable)
✅ Stock in downtrend (below 10 or 20-day SMA)
✅ Previous 1–3 days red (selling exhaustion)
✅ Volume spike (1.5–2.5× average = institutional buying)
✅ High delivery % (40–60% = genuine buying, not speculation)
✅ Min price ₹50–₹100 (removes penny/illiquid stocks)
Why the optimizer matters: The base pin bar alone gives ~49–55% win rate because it fires on everything. Adding filters narrows it to high-quality setups only. The optimizer finds which combination of filters gives the highest win rate on YOUR data (2020–2026). The best combo is automatically used for live alerts.
