* Add Fear & Greed Index 2.0 reverse engineering brief Analyzes the 10-category weighted composite (Sentiment, Volatility, Positioning, Trend, Breadth, Momentum, Liquidity, Credit, Macro, Cross-Asset) with scoring formulas, data source audit, and implementation plan for building it as a worldmonitor panel. https://claude.ai/code/session_01HR69u6oF1VCMwsC2PHFL8i * Add seed script implementation plan to F&G brief Details exact endpoints, Yahoo symbols (17 calls), Redis key schema, computed metrics, FRED series to add (BAMLC0A0CM, SOFR), CNN/AAII sources, output JSON schema, and estimated runtime (~8s per seed run). https://claude.ai/code/session_01HR69u6oF1VCMwsC2PHFL8i * Update brief: all sources are free, zero paid APIs needed - CBOE CDN CSVs for put/call ratios (totalpc.csv, equitypc.csv) - CNN dataviz API for Fear & Greed (production.dataviz.cnn.io) - Yahoo Finance for VIX9D/VIX3M/SKEW/RSP/NYA (standard symbols) - FRED for IG spread (BAMLC0A0CM) and SOFR (add to existing array) - AAII scrape for bull/bear survey (only medium-effort source) - Breadth via RSP/SPY divergence + NYSE composite (no scraping) https://claude.ai/code/session_01HR69u6oF1VCMwsC2PHFL8i * Add verified Yahoo symbols for breadth + finalized source list New discoveries: - ^MMTH = % stocks above 200 DMA (direct Yahoo symbol!) - C:ISSU = NYSE advance/decline data - CNN endpoint accepts date param for historical data - CBOE CSVs have data back to 2003 - 33 total calls per seed run, ~6s runtime All 10 categories now have confirmed free sources. https://claude.ai/code/session_01HR69u6oF1VCMwsC2PHFL8i * Rewrite F&G brief as forward-looking design doc Remove all reverse-engineering language, screenshot references, and discovery notes. Clean structure: goal, scoring model, data sources, formulas, seed script plan, implementation phases, MVP path. https://claude.ai/code/session_01HR69u6oF1VCMwsC2PHFL8i * docs: apply gold standard corrections to fear-greed-index-2.0 brief * feat(market): add Fear & Greed Index 2.0 — 10-category composite sentiment panel Composite 0-100 index from 10 weighted categories: sentiment (CNN F&G, AAII, crypto F&G), volatility (VIX, term structure), positioning (P/C ratio, SKEW), trend (SPX vs MAs), breadth (% >200d, RSP/SPY divergence), momentum (sector RSI, ROC), liquidity (M2, Fed BS, SOFR), credit (HY/IG spreads), macro (Fed rate, yield curve, unemployment), cross-asset (gold/bonds/DXY vs equities). Data layer: - seed-fear-greed.mjs: 19 Yahoo symbols (150ms gaps), CBOE P/C CSVs, CNN F&G API, AAII scrape (degraded-safe), FRED Redis reads. TTL 64800s. - seed-economy.mjs: add BAMLC0A0CM (IG spread) and SOFR to FRED_SERIES. - Bootstrap 4-file checklist: cache-keys, bootstrap.js, health.js, handler. Proto + RPC: - get_fear_greed_index.proto with FearGreedCategory message. - get-fear-greed-index.ts handler reads seeded Redis data. Frontend: - FearGreedPanel with gauge, 9-metric header grid, 10-category breakdown. - Self-loading via bootstrap hydration + RPC fallback. - Registered in panel-layout, App.ts (prime + refresh), panel config, Cmd-K commands, finance variant, i18n (en/ar/zh/es). * fix(market): add RPC_CACHE_TIER entry for get-fear-greed-index * fix(docs): escape bare angle bracket in fear-greed brief for MDX * fix(docs): fix markdown lint errors in fear-greed brief (blank lines around headings/lists) * fix(market): fix seed-fear-greed bugs from code review - fredLatest/fredNMonthsAgo: guard parseFloat with Number.isFinite to handle FRED's "." missing-data sentinel (was returning NaN which propagated through scoring as a truthy non-null value) - Remove 3 unused Yahoo symbols (^NYA, HYG, LQD) that were fetched but not referenced in any scoring category (saves ~450ms per run) - fedRateStr: display effective rate directly instead of deriving target range via (fedRate - 0.25) which was incorrect * fix(market): address P2/P3 review findings in Fear & Greed - FearGreedPanel: add mapSeedPayload() to correctly map raw seed JSON to proto-shaped FearGreedData; bootstrap hydration was always falling through to RPC because seed shape (composite.score) differs from proto shape (compositeScore) - FearGreedPanel: fix fmt() — remove === 0 guard and add explicit > 0 checks on VIX and P/C Ratio display to handle proto default zeros without masking genuine zero values (e.g. pctAbove200d) - seed-fear-greed: remove broken history write — each run overwrote the key with a single-entry array (no read-then-append), making the 90-day TTL meaningless; no consumer exists yet so defer to later - seed-fear-greed: extract hySpreadVal const to avoid double fredLatest call - seed-fear-greed: fix stale comment (19 symbols → 16 after prior cleanup) --------- Co-authored-by: Claude <noreply@anthropic.com>
