🚀 Build a Professional Trading Bot | Episode 6 – Execution Engine

A trading signal is not a trade.

In this episode, we build one of the final core components of a professional algorithmic trading system: the Execution Engine.

You’ll learn how trading signals are safely transformed into real broker orders, why positions and active orders must always be checked before execution, and how broker callbacks keep your trading system synchronized with reality.

More importantly, you’ll see how keeping every component focused on a single responsibility leads to a clean, professional architecture that is easy to extend and maintain.

In this episode we cover:

✅ Why a BUY signal should NOT immediately become an order
✅ Position management and active order checks
✅ The Runtime (State) class
✅ Broker callbacks for positions, orders and order status
✅ Designing a clean Execution Engine
✅ Building and submitting market orders
✅ Watching the entire trading system execute its first complete trade

By the end of this episode, our trading bot is capable of placing its very first live (or paper) trade.
