Safety Rules

1. Default to paper trading. Never set APCA_API_BASE_URL to live without explicit user confirmation. 2. Show the order JSON before submitting. Let the user confirm symbol, qty, side, and type. 3. Check market clock before placing orders — stocks only trade during market hours (9:30-16:00 ET) unless extended_hours: true on limit orders. 4. Verify buying power via GET /v2/account before large orders. 5. Never provide financial advice. Present data; let the user decide. 6. Warn about irreversible actions — closing all positions, canceling all orders.

Troubleshooting

| Symptom | Fix | |---------|-----| | HTTP 401 | Check APCA_API_KEY_ID / APCA_API_SECRET_KEY are set and valid | | HTTP 403 | Paper keys on live URL or vice versa; check APCA_API_BASE_URL | | HTTP 422 (insufficient qty) | Check buying power, fractional support, or symbol validity | | HTTP 429 | Rate limited — wait and retry; Alpaca allows 200 req/min | | Order rejected outside hours | Add "extended_hours":true (limit orders only) or wait for market open | | jq: command not found | Script falls back to python3 -m json.tool; install jq for better output |
