Custom Stock Algo Trading Bot

I want to automate my stock-market activity with a purpose-built algorithmic system. The core requirement is straightforward: the code must execute fully automated stock trading—including order placement, position management, and real-time monitoring—through a reliable broker API. I did not lock myself into a single strategy yet, so I’m happy to discuss momentum, mean-reversion, or any approach you can justify with solid back-testing metrics.

The final solution should:
• Connect to leading U.S. exchanges (think NYSE or NASDAQ) with low-latency data feeds.
• Include a transparent configuration panel where I can tweak risk limits, position size, and entry/exit parameters without touching the source code.
• Deliver reproducible back-test reports alongside the live-trading module so performance can be verified before we flip the switch.

You’re free to build in Python, C++, or another language you favour, provided the code is clean, documented, and comes with clear deployment instructions for a VPS or cloud instance.

When you reply, tell me briefly which broker API you would use, how you would structure the back-testing, and the timeline you need to reach a paper-trading milestone.
