Project description:
"My algorithm on QuantConnect’s LEAN engine runs correctly but it’s painfully slow: backtests crawl and live orders hesitate. I need a specialist who can dive into the existing code, pinpoint what’s throttling execution speed, and deliver a leaner, faster version without changing the trading logic.

This is a debugging assignment focused purely on performance. The strategy itself already behaves as intended; the issue is speed, not logic or unexpected results. Code errors aren’t the problem either—just sluggish execution.

Here’s what I’d like back from you:
• A revised algorithm (same language as the original—Python or C#) that matches current trade outputs while running noticeably faster on QuantConnect’s cloud or local LEAN CLI.
• A brief, clear report outlining the bottlenecks you found, the optimizations applied, and before-vs-after timing metrics.
• Any quick-win suggestions for further speed improvements or resource configuration inside QuantConnect.

You should be comfortable profiling with tools such as cProfile, dotTrace, or similar, and familiar with LEAN’s data access patterns, event handlers, and warm-up quirks. I’ll give you repository access as soon as we have an NDA in place so you can start hunting down those bottlenecks right away." (client-provided description)
