feat: add 67 new endpoints across 10 feature groups
...
Prerequisite refactor:
- Consolidate duplicate _to_dicts into shared obb_utils.to_list
- Add fetch_historical and first_or_empty helpers to obb_utils
Phase 1 - Local computation (no provider risk):
- Group I: 12 technical indicators (ATR, ADX, Stoch, OBV, Ichimoku,
Donchian, Aroon, CCI, Keltner, Fibonacci, A/D, Volatility Cones)
- Group J: Sortino, Omega ratios + rolling stats (variance, stdev,
mean, skew, kurtosis, quantile via generic endpoint)
- Group H: ECB currency reference rates
Phase 2 - FRED/Federal Reserve providers:
- Group C: 10 fixed income endpoints (treasury rates, yield curve,
auctions, TIPS, EFFR, SOFR, HQM, commercial paper, spot rates,
spreads)
- Group D: 11 economy endpoints (CPI, GDP, unemployment, PCE, money
measures, CLI, HPI, FRED search, balance of payments, Fed holdings,
FOMC documents)
- Group E: 5 survey endpoints (Michigan, SLOOS, NFP, Empire State,
BLS search)
Phase 3 - SEC/stockgrid/FINRA providers:
- Group B: 4 equity fundamental endpoints (management, dividends,
SEC filings, company search)
- Group A: 4 shorts/dark pool endpoints (short volume, FTD, short
interest, OTC dark pool)
- Group F: 3 index/ETF enhanced (S&P 500 multiples, index
constituents, ETF N-PORT)
Phase 4 - Regulators:
- Group G: 5 regulatory endpoints (COT report, COT search, SEC
litigation, institution search, CIK mapping)
Security hardening:
- Service-layer allowlists for all getattr dynamic dispatch
- Regex validation on date, country, security_type, form_type params
- Exception handling in fetch_historical
- Callable guard on rolling stat dispatch
Total: 32 existing + 67 new = 99 endpoints, all free providers.
