        # Alpaca limit: 200 requests/minute
        self._rate_limiter = RateLimiter(max_calls=200, period=60)
        self._session = requests.Session()

    def _api_request(self, method: str, url: str, **kwargs):
        """Make rate-limited API request."""
        @self._rate_limiter
        def _call():
            return self._session.request(method, url, **kwargs)

USER tradingagents
```

---

### Fix 6: Input Validation (2 hours)

**File:** `web_app.py`

```python
from tradingagents.security import validate_ticker
from decimal import Decimal, InvalidOperation

async def main(message: cl.Message):
    msg_content = message.content.strip()
    parts = msg_content.split()

    if not parts:
        await cl.Message(content="Please enter a command.").send()
        return

    command = parts[0].lower()

    # Analyze command
    if command == "analyze":
        if len(parts) < 2:
            await cl.Message(content="Usage: `analyze TICKER`").send()
            return

        try:
            ticker = validate_ticker(parts[1])  # ADD VALIDATION
            await analyze_stock(ticker)
        except ValueError as e:
            await cl.Message(content=f"Invalid ticker: {e}").send()

    # Buy command
    elif command == "buy":
        if len(parts) < 3:
            await cl.Message(content="Usage: `buy TICKER QUANTITY`").send()
            return

        try:
            ticker = validate_ticker(parts[1])  # ADD VALIDATION
            quantity = Decimal(parts[2])

            # VALIDATE QUANTITY
            if quantity <= 0:
                raise ValueError("Quantity must be positive")
            if quantity > Decimal('100000'):
                raise ValueError("Quantity too large (max 100,000)")

            await execute_buy(ticker, quantity)

        except (ValueError, InvalidOperation) as e:
            await cl.Message(content=f"Invalid input: {e}").send()

    # Apply same pattern to sell command
```

---

### Fix 7: Thread Safety (1 hour)

**File:** `web_app.py:26-27`

```python
# BEFORE (UNSAFE):
ta_graph: Optional[TradingAgentsGraph] = None
broker: Optional[AlpacaBroker] = None

# AFTER (SAFE):
# Remove global variables, use session storage

@cl.on_chat_start
async def start():
    cl.user_session.set("ta_graph", None)
    cl.user_session.set("broker", None)
    cl.user_session.set("config", DEFAULT_CONFIG.copy())

async def analyze_stock(ticker: str):
    # Get from session instead of global
    ta_graph = cl.user_session.get("ta_graph")

    if ta_graph is None:
        config = cl.user_session.get("config")
        ta_graph = TradingAgentsGraph(config=config)
        cl.user_session.set("ta_graph", ta_graph)

    # ... rest of function

# Apply same pattern to all functions using global state
```

---

### Fix 8: Return Type Hints (2 hours)

Add to all functions in:
- `tradingagents/llm_factory.py`
- `tradingagents/brokers/alpaca_broker.py`
- `web_app.py`

```python
from typing import Optional, List, Union
from langchain_openai import ChatOpenAI
from langchain_anthropic import ChatAnthropic
from langchain_google_genai import ChatGoogleGenerativeAI

LLMType = Union[ChatOpenAI, ChatAnthropic, ChatGoogleGenerativeAI]

@staticmethod
def create_llm(
    provider: str,
    model: str,
    temperature: float = 1.0,
    max_tokens: Optional[int] = None,
    backend_url: Optional[str] = None,
    **kwargs
) -> LLMType:  # ADD THIS
    ...

def connect(self) -> bool:  # ADD THIS
    ...

def get_account(self) -> BrokerAccount:  # ADD THIS
