Data Source Priority - Alpaca API MANDATORY (v3.6.0)
CRITICAL POLICY
Alpaca API is the ONLY valid source for OHLCV (price/volume) data.
yfinance is NEVER a valid fallback for market data. Any code that falls back to yfinance for price or volume data is a BUG that must be fixed.
Permitted yfinance Usage (ONLY)
| Use Case | Permitted? | Notes |
|---|---|---|
| OHLCV data (price/volume) | NO - NEVER | Use Alpaca API only |
| Sector/Industry lookup | Yes | Equity symbols only, not crypto |
| Company info | Yes | For display purposes only |
| Dotted symbols (.WS, .PR) | NO | Exclude from yfinance entirely |
