Strategy Startup Guardrails

Quick Checklist (before launch)

• Imports: avoid shadowing time; use from datetime import time as dt_time and import time as time_module for timestamps.
• Market hours helpers: call dt_time(...), not time(...) if time is a module.
• Config/env: confirm OPENALGO_APIKEY, broker creds, and host/port.
• Data readiness: master contracts downloaded for required exchanges/symbols.
• History preflight: run one manual history request with real payload (see history-payload-validator).
