+## Dashboard
+
+The FastAPI dashboard provides read-only monitoring of the trading system.
+
+### Starting the Dashboard
+
+```bash
+# Via CLI flag
+python -m src.main --mode=paper --dashboard
+
+# Via environment variable
+DASHBOARD_ENABLED=true python -m src.main --mode=paper
+```
+
+Dashboard runs as a daemon thread on `DASHBOARD_HOST:DASHBOARD_PORT` (default: `127.0.0.1:8080`).
+
+### API Endpoints

+|----------|-------------|
+| `GET /` | HTML dashboard UI |
+| `GET /api/status` | Daily trading status by market |

+| `GET /api/decisions` | Decision log entries (query: `limit`, `market`) |
+| `GET /api/scenarios/active` | Today's matched scenarios |
+

+
+| Command | Description |
+|---------|-------------|
+| `/help` | List available commands |
