Webhook Handler


@app.post("/webhook")
async def webhook_handler(request: Request):
    data = await request.json()
    
    # Validate incoming signal
    if not validate_signal(data):
        logger.error("Invalid signal format")
        return {"status": "error", "message": "Invalid signal format"}
    
    # Process trading signal
    try:
        strategy = StrategyExecutor(data)
        result = await strategy.execute()
        return {"status": "success", "data": result}
    except Exception as e:
        logger.error(f"Strategy execution failed: {str(e)}")
        return {"status": "error", "message": str(e)}

Risk Management Implementation


class RiskManager:
    def __init__(self, config):
        self.max_position_size = config.MAX_POSITION_SIZE
        self.max_exposure = config.MAX_EXPOSURE
        self.stop_loss_pct = config.STOP_LOSS_PCT

    async def validate_trade(self, trade_params):
        # Check account balance
        balance = await self.get_account_balance()
        if trade_params.size > self.max_position_size * balance:
            raise RiskLimitExceeded("Position size exceeds maximum allowed")
        
        # Check total exposure
        current_exposure = await self.get_total_exposure()
        if current_exposure + trade_params.size > self.max_exposure:
            raise RiskLimitExceeded("Total exposure limit exceeded")
        
        return True
