- yfinance>=0.2.40 added as a hard dependency
- _fetch_yfinance_fallback(): pulls OHLCV from Yahoo for symbols not on
the Twelve Data free tier (XAUUSD → GC=F, XAGUSD → SI=F)
- Hooked into both batch and single-symbol fetch paths; logs as [yf]
to distinguish from Twelve Data [live]
- Fail-loud: if both providers return nothing, the pair is skipped with
the existing "data unavailable" message
- _analyze_all_tfs accepts an async progress callback; both /signal and
/scan now show coarse milestones via message edits:
"📡 Fetching market data..." → "🧠 Analyzing pairs..." → result
- prefetch_batch is now run in a thread so it doesn't block the event loop
