Sterling Trader Pro API Integration

My C#-based desktop trading front end now needs a direct, real-time link to Sterling Trader Pro. The goal is full API integration that goes beyond a simple data feed: live quotes and depth, every order type Sterling supports, position & risk updates, plus a back-testing harness on the same codebase so strategies can run historically before they trade live.

The current application is stable and well-structured; what is missing is the Sterling layer—authentication, session management, event handling, and the conversion of our existing order objects to Sterling’s message format. All work must remain in C# and respect Sterling’s API guidelines.

Deliverables
• Connection module that authenticates and maintains a persistent Sterling session
• Real-time market data stream wired to our existing UI models
• Order router handling market, limit, stop, synthetic, and algo orders, with callbacks for partials, cancels, rejects, and fills
• Risk/position synchronization pulled from Sterling at configurable intervals
• Back-testing wrapper that reuses the same order/execution code path against historical data sets
• Brief setup document and commented code for internal maintenance

Acceptance Criteria
• End-to-end execution tested on Sterling’s demo environment with sample strategies
• Latency under 100 ms round-trip for market orders on a local connection
• All API exceptions caught and logged without crashing the host application

If you have previous Sterling Trader Pro experience—or deep familiarity with similar broker APIs—this should be a straightforward but rewarding integration project.
