## **Developer Brief: Debugging a Python Trading API for International Brokers**
### **1. Project Overview**
We have developed a Python-based trading API that integrates with international brokers. Each component of the system works individually, including market data retrieval, order management, and risk controls. However, we are experiencing a **bug during order execution** when all parts are combined. We need a skilled Python developer with experience in trading APIs to debug and resolve this issue.
---
### **2. Scope of Work**
- **Review & Debug Order Execution Logic**
- Analyze the current code structure and execution flow.
- Identify the cause of the execution failure when all components are running together.
- Ensure smooth order placement, modification, and cancellation.
- **API Integration Check**
- Verify API requests to the broker (e.g., Interactive Brokers, Binance, FXCM).
- Ensure the API is handling authentication, rate limits, and response parsing correctly.
- **Concurrency & Synchronization Debugging**
- Identify potential race conditions or conflicts between market data retrieval and order execution.
- Debug any issues related to WebSocket connections, threading, or async operations.
- **Logging & Error Handling Improvements**
- Implement detailed logging to capture errors in the execution process.
- Ensure the system properly retries failed requests or handles API timeouts gracefully.
---
### **3. Technical Details**
- **Programming Language:** Python
- **Libraries Used:** Requests, WebSocket, Pandas, NumPy, ccxt (for crypto), IB-Insync (for Interactive Brokers)
- **Database (if applicable):** PostgreSQL / MySQL / SQLite
- **Hosting/Execution:** AWS, Google Cloud, or local
---
### **4. Expected Deliverables**
- Fully debugged and tested Python script where order execution functions correctly.
- Clear documentation on the fix and any changes made.
- A log/debugging framework to monitor future execution errors.
---
### **5. Timeline & Budget**
- **Project completion:** **4-5 days**
- **Milestones:**
- **Day 1:** Code review & issue identification
- **Day 2:** Debugging order execution logic
- **Day 3:** Testing and fixing API integration issues
- **Day 4:** Stress testing & final fixes
- **Day 5:** Documentation & handover
- **Budget:** $XX – $XX (negotiable based on experience and speed of delivery)
---
### **6. Additional Requirements**
- Experience with **Interactive Brokers API, Binance API, or similar**.
- Prior work in **algorithmic trading or fintech development** is a plus.
- Strong understanding of **asynchronous programming, WebSockets, and API rate limits**.
---
### **7. Contact & Next Steps**
If you're interested, please provide:
✅ Your experience with trading APIs.
✅ Examples of similar debugging projects.
✅ Estimated time to fix & expected cost.

This version clearly states that the **code is already built** but has an execution bug when all components run together. Let me know if you need further refinements! ?
