I Luk Kim	bb2a06ce6e	fix: reduce Alpaca multi-bar batch_size 200 → 100 Community reports 502 above ~100 symbols per request. Official docs have no stated limit but 200 appears to be a ceiling. 100 is a safe conservative default that avoids the 502 edge case with minimal performance impact (500 tickers = 5 batches instead of 3).

I Luk Kim	38207d342c	fix: Alpaca intraday 503 — auto-select feed=iex for free plan Free plan blocks SIP intraday data (403). IEX feed is free and real-time. - _default_feed(): returns 'iex' for intraday timeframes, None for daily+ - get_bars() / get_multi_bars(): apply default feed automatically - Callers can override with feed='sip' if on paid plan Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	4 months ago
I Luk Kim	fbb42edfc2	feat: multi-ticker bulk bars endpoints + BF-B ticker normalization - GET /api/v1/price/data?tickers=AAPL,MSFT,BF-B&start_date=...&end_date=... → multi-ticker daily OHLCV via Alpaca (ORB engine daily bars interface) - GET /api/v1/alpaca/intraday?tickers=...&interval=5min&start_date=...&end_date=... → multi-ticker intraday OHLCV via Alpaca (ORB engine ORB-window interface) - AlpacaMultiBarsResponse schema: {source, interval, count, bars: {sym → [bar]}} - normalize_ticker(): BF-B→BF.B, BRK-B→BRK.B applied in get_bars/get_multi_bars/get_snapshot(s) - get_multi_bars: transparent batching (200 symbols/request) + INTERVAL_MAP aliases (5min, 15min, 60min, …) - Response re-keys Alpaca normalized symbols back to original input names Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	4 months ago

I Luk Kim	bf6932ca2f	Add Alpaca-specific DB table and Redis caching for Alpaca/FINRA endpoints Separate Alpaca price data into dedicated AlpacaPriceData table to avoid UniqueConstraint('ticker', 'date') conflicts with Yahoo Finance PriceData. Add Redis caching (build_cache_key/get_cached_response/set_cached_response) to 3 Alpaca endpoints and 2 FINRA query endpoints with appropriate TTLs.
