""" system_verification_v1.py ========================== End-to-end verification that every component of the live system is correctly configured and working before trusting it with real trades. Checks: 1. Rate data files — present, fresh, correct format 2. MT5 connection — connected, correct account, balance correct 3. Signal pipeline — z-score computes correctly from MT5 bars 4. Position sizing — lot size calculates correctly for each z-band 5. Order logic — TP and SL levels calculate correctly 6. Fast poll — ARMED state initialises and clears correctly 7. 52h hold logic — correctly tracks time, does not block new signals 8. Position close detection — STATE resets when position closes 9. Rate update logic — ECB fallback present in auto_rates_loader 10. Entry method — Fib 0.786 is configured, not market entry Run on VPS to verify the live system end-to-end: python src/research/system_verification_v1.py Expected: all checks PASS. Any FAIL needs investigating before live trading.
