Order Guardrails:
- Symbol validation — Rejects invalid/unknown tickers
- Buying power check — Blocks orders exceeding available funds, shows max shares
- Duplicate detection — Warns if you have open orders for same symbol/side
- Price validation — Warns if limit price is worse than market
- Market hours check — Detects pre-market, after-hours, and closed sessions
- Pre-market (4:00 AM - 9:30 AM ET): Option to place pre-market order
- After-hours (4:00 PM - 8:00 PM ET): Option to place after-hours order
- Closed: Warns order will queue until market open
- Cost confirmation — Shows total cost and requires confirmation
Use --force to skip all confirmation prompts (use with caution).
