Backtest & Code Momentum Strategies

I need backtesting for several momentum-based stock trading strategies and, once the numbers check out, a clean piece of code that automates each setup end-to-end.

Here is what I already have on hand and will share the moment we start:
• Historical price data for all tickers involved
• A library of technical indicators calculated for the same period

Your first task is to run a rigorous backtest on every strategy, report the key performance metrics, drawdowns, trade statistics, and an equity curve that I can easily interpret. If tweaks are required, we will iterate until the logic is solid.

When the strategy logic is confirmed, I want it coded in a production-ready script (Python, Pine Script, or another language you recommend). The final deliverable should:
• Reproduce the tested results when fed the same data
• Be clearly commented so I can adjust parameters later
• Include a short read-me explaining installation and usage

Please tell me which toolset you plan to use for the backtest and for the live code and roughly how long each phase will take.
