Yijia-Xiao	9fd54f8368	fix(data): reject stale yfinance OHLCV instead of reporting wrong prices ... yfinance intermittently returns a year-old partial frame (e.g. June 2025 rows for a June 2026 request) that still has rows and a Close, so it passed the empty-check and silently fed a wrong close price and indicators into the report (#1021). Add a freshness guard that rejects a frame whose latest row is far older than the requested date, on both the raw OHLCV path and the indicator path. It raises the existing NoMarketDataError with a stale-specific detail, so the vendor router's try-next-vendor and single unavailable-signal handling apply unchanged; the sentinel now surfaces that detail so the agent reports the specific reason rather than fabricating a value.	2026-06-14 07:10:15 +00:00
Yijia-Xiao	dab07688fb	fix(data): include the requested end date in yfinance fetches ... yfinance treats end as exclusive, so get_YFin_data_online dropped the requested end_date row and load_ohlcv dropped the current day. Request one day past the end so the range is inclusive (look-ahead is still prevented by the curr_date filter; the header still shows the requested range). Also correct the load_ohlcv docstring to the 5-year window it actually downloads.	2026-06-13 21:30:11 +00:00
Yijia-Xiao	1ff3f07a73	fix: support commodity/forex/crypto tickers and never invent prices (#781) ... Analyzing a symbol Yahoo Finance does not recognize (e.g. XAUUSD+) could produce an invented price instead of an error. The agent now either prices the correct instrument or clearly reports that data is unavailable. Ticker support: - Commodities/forex/crypto resolve to the symbol Yahoo actually serves, so you can enter the common form and it just works: XAUUSD / XAUUSD+ / GOLD -> GC=F (gold) USOIL -> CL=F (WTI crude) EURUSD -> EURUSD=X BTCUSD -> BTC-USD SPX500 / NAS100 -> ^GSPC / ^NDX Native Yahoo symbols (AAPL, GC=F, ^GSPC) keep working unchanged. New instruments are added by extending the alias table. Reliability: - Unknown or delisted symbols now return a clear "data unavailable" result the agent reports verbatim, instead of a value the model fills in. - A failed fetch no longer leaves a broken symbol cached until the cache is cleared by hand.	2026-05-31 22:38:47 +00:00
