Reverse-Engineer Exact Match Pine Strategy

I have a closed-source TradingView strategy whose trade history I need to mirror line-for-line. Your job is to rebuild it in open Pine Script so that its back-test produces the very same entry and exit signals I see now—no deviations in fills, prices, or timestamps. When I toggle TradingView’s Bar Replay the signals must remain visible, and the code has to function on my chosen seconds and minute chart combinations without breaking synchronicity.

To guide you:
• Matching criterion: every historical buy/sell signal needs to coincide with the original back-test on the same bar.
• Time-frame scope: seconds and minute charts that I specify during testing (not just the original default).
• Core logic must stay intact; feel free to optimise structure or performance as long as results are identical.
• Deliver clean, fully commented, non-repainting Pine Script v5 code plus a brief setup note so I can confirm parity on my end.

I will validate the work by overlaying both strategies on several chosen charts in replay mode and checking for 100 % signal alignment.
