…rough brighter, especially in the center of the hero.
- Add KMeans clustering for market activity patterns (4 clusters) - Add volatility skew/smile pattern detection with quadratic fitting - Add IV spike/shift detection using z-score analysis - Add AI-driven insight generation combining anomaly, volume, OI, volatility - Add /api/ai-insights endpoint for real-time AI insights - Add /api/volatility-surface endpoint for 3D IV visualization - Add /api/volume-surface endpoint for volume distribution - Add /api/pattern-analysis endpoint for comprehensive pattern analysis"
- Fix Vite proxy target from port 5000 to 8000 - Map all frontend API calls to actual backend endpoints - Add new API functions: anomalies, greeks, max-pain, volatility-surface - Add pattern-analysis, volume-surface, metrics, spot-price endpoints - Increase API timeout to 30s for data-heavy endpoints"
- Add AnomalyScatterChart for ML anomaly detection visualization - Add GreeksChart for options Greeks (Delta) across strikes - Add PCRTimeseriesChart for Put-Call Ratio over time with spot overlay - Add VolatilitySurfaceChart for 3D IV visualization across strike/expiry - Add VolumeProfileChart for stacked Call/Put volume by strike - Enhance VolatilitySmileChart to show both Call IV and Put IV curves"
…s, pattern badges - 8 metric cards: Spot, ATM Strike, PCR, Sentiment, Total OI, Volume, Anomalies, Volume Spikes - OI Distribution + Volume Profile side-by-side - Volatility Analysis: Smile + Surface charts with skew/smile detection badges - Pattern Analysis summary: skew direction, smile curvature, clusters, IV spikes - Time Series: PCR Timeseries with spot overlay + Cumulative OI - Activity Heatmap section - AI Pattern Detection: Anomaly Scatter (Isolation Forest) + Greeks Delta chart - AI Insights panel with real-time insight count
…rmat - Maps datetime to time labels, total_oi_CE/PE to cumulative_oi_ce/pe - Backwards compatible with existing data format
- Removed BANKNIFTY, FINNIFTY, SENSEX (no training data exists for these) - Sidebar now fetches available expiries from /api/expiries endpoint - Removed hardcoded fake dates (2026-03-10, 2026-03-17)
- Removed stacking (bars were invisible due to small values) - Added empty state message when no volume data - Filters out zero-volume strikes
…ptions - Shows loading spinner while data fetches from backend - Market Pulse section labeled 'NIFTY' explicitly - All chart subtitles rewritten for non-expert readability - Pattern analysis cards have helper descriptions (skew, smile, clusters) - CumulativeOIChart gets legend for Call/Put OI
Removed author section from README.
