## Provider Architecture
### Dual Provider Model
- **MSN Finance** — default provider. Rich data: quotes, fundamentals, profile, earnings, financials, sentiment, insights, news, screener. No history for IDX stocks.
- **Yahoo Finance** — history fallback. Reliable OHLCV data via `/v8/finance/chart/`.
- **MSN Finance** — default provider. Rich data: quotes, fundamentals, profile, earnings, financials, sentiment, insights, news, screener, and explicit price-only chart history for supported IDX windows.
- **Yahoo Finance** — default/auto history source. Reliable OHLCV data via `/v8/finance/chart/`.
### Hybrid History Strategy
When `history_provider = auto` (default):
1. Check if current provider supports `HistoryProvider` trait
2. MSN doesn't → transparently fallback to Yahoo
3. Log info message: `"history provider fallback active (msn -> yahoo)"`
1. Use Yahoo for history because it provides full OHLCV candles.
2. Keep logging when provider selection falls back from MSN to Yahoo.
3. Allow explicit `--history-provider msn` for supported MSN chart windows (`1mo`, `3mo`, `1y` with `1d` interval).
MSN Charts are price-only for IDX. The CLI normalizes them into `Ohlc` rows by
using the chart price as open/high/low/close and `0` volume.
