## Required SDK Calls

```python
import os
from longport import openapi

# Load env
bashrc = open(os.path.expanduser("~/.bashrc")).read()
for line in bashrc.splitlines():
    if line.startswith("export LONGPORT_") or line.startswith("export LONGBRIDGE_"):
        parts = line.replace("export ", "").split("=", 1)
        if len(parts) == 2:
            os.environ[parts[0]] = parts[1].strip('"').strip("'")

os.environ["LONGBRIDGE_TRADE_ENABLED"] = "true"

cfg = openapi.Config.from_env()
trade_ctx = openapi.TradeContext(config=cfg)
quote_ctx = openapi.QuoteContext(config=cfg)

# Quote
resp = quote_ctx.quote(["SYMBOL.US"])
price = float(resp[0].last_done)

# Position (check available_quantity for sellable qty)
pos = trade_ctx.stock_positions()
for ch in pos.channels:
    for p in ch.positions:
        avail = int(p.available_quantity)
        total = int(p.quantity)

# Pending orders
orders = trade_ctx.today_orders()
for o in orders:
    status = str(o.status)  # "NotReported", "PendingStatus", etc.

# Place order (GTC + outside RTH = works pre/regular/post market)
resp = trade_ctx.submit_order(
    symbol="RGTI.US",
    order_type=openapi.OrderType.LO,
    side=openapi.OrderSide.Sell,
    submitted_quantity=15,
    time_in_force=openapi.TimeInForceType.GoodTilCanceled,
    submitted_price=21.00,
    outside_rth=openapi.OutsideRTH.AnyTime,
)

# Cancel
trade_ctx.cancel_order(order_id)
```

## State File Pattern

Track active orders and cooldowns to prevent spam:

```python
STATE_FILE = "~/.hermes/scripts/rgti_t_state.json"

def load_state():
    try:
        return json.load(open(STATE_FILE))
    except:
        return {"active_orders": [], "last_action_time": None, "trades_today": 0}

# Cooldown: 5 min between actions
last_t = state.get("last_action_time")
if last_t:
    diff = (now - datetime.fromisoformat(last_t)).total_seconds()
    if diff < 300:
        sys.exit(0)  # silent exit
```

## Cron Job Setup

```python
# Via Hermes cronjob tool:
cronjob(action="create",
    name="RGTI半自动做T挂单",
    no_agent=True,           # Script-only, no LLM
    schedule="*/10 9-15 * * 1-5",  # Every 10 min, 9-15 ET, Mon-Fri
    deliver="weixin",
    script="rgti_auto_monitor.py")  # Relative to ~/.hermes/scripts/
```

## Key Design Decisions

1. **No agent (no_agent=True)**: Script runs directly, prints output → delivered as message. No LLM tokens wasted.
2. **Empty stdout = silent**: If nothing to report, print nothing → no message sent.
3. **GTC + AnyTime**: Orders persist across days and work in pre/post market.
4. **5-min cooldown**: Prevents rapid-fire order spam on volatile stocks.
5. **Auto-cancel stale orders**: If price moves >$1.50 from order price, cancel and re-evaluate.
6. **State file for order tracking**: Prevents duplicate orders and tracks today's trade count.
