A signal-to-order execution system was developed to automate the trading workflow from validated market signals through broker execution. The architecture combines trade validation, order management, risk controls, broker connectivity, and operational monitoring in a single workflow.
Automated Signal Processing
TrendSpider signals were received through a FastAPI service and validated before reaching the execution layer. The workflow supported long, short, market, and conditional trading scenarios to allow different strategies. It enabled the bot to follow the defined execution rules without manual order entry.
Controlled Order Execution
Validated trade instructions were translated into Interactive Brokers orders through the TWS/Gateway API. The execution logic handled order submission and status tracking, while maintaining the connection between incoming strategy signals and broker activity.
Built-In Risk Controls
Position sizing was calculated using available capital and predefined leverage settings. Bracket-order logic linked entries with corresponding take-profit and stop-loss orders. This allowed the system to apply the protective controls as part of the trade, rather than adding them manually.
Secure Trade Validation
Bearer-token authentication and request validation were implemented at the API layer before instructions could reach the trading engine. This created a controlled entry point for incoming signals and helped prevent invalid or unauthorized requests from triggering trades.
Execution Monitoring
Connection health checks, structured exception handling, and order-state tracking provided visibility into broker activity. The system could identify filled, cancelled, or rejected orders and surface connectivity or execution issues without relying solely on the Interactive Brokers workstation.
Real-Time Notifications
Slack notifications were integrated for execution events, failures, and connection issues. They were complemented by account-summary access and structured logging to provide remote visibility into trading activity. All these things made operational issues easier to identify.
