I want to turn my proprietary strategy into a maintenance-free trading algorithm. Speed and reliability are everything here—during testing I will judge the build almost entirely on raw execution time and a near-zero error rate and friendly UI. You’ll translate my written rules into well-structured, low-latency code, wire it to the XTS Terminal API (my first choice, yet I’m happy to consider another brokerage or data feed if you can prove it performs better), and expose a simple interface where I can tweak order size, risk parameters, and trading hours without touching the codebase afterwards. Because I want this to run unattended, you’ll also need to implement robust logging, automatic reconnection logic, and graceful shutdown routines. Expect to spend a fair amount of energy on optimisation—tight data structures, non-blocking calls, and efficient market-data handling are essential. Deliverables • Clean, well-documented source code of the trading algorithm • Lightweight GUI or web panel for parameter tweaks • Integration module for XTS Terminal (or the agreed alternative) with full test coverage • Performance report benchmarking execution speed and error rate in live-sim and back-tests • Deployment script or container so I can drop it straight onto my VPS Acceptance criteria The solution is accepted once it: 1. Executes orders within the latency target we will finalise together (sub-100 ms round-trip is my expectation). 2. Runs unattended for 2 trading week without manual intervention. 3. Logs zero unhandled exceptions and no missed fills attributable to the algorithm. 4. Easy to adapt to UI I have set aside roughly ₹43 000 for the complete job and would like to wrap everything up within 3–5 weeks.
