TradingView Pine Script Mean Reversion Bot

I already have a clear idea of the mean-reversion logic I want to trade and now need it translated into a solid, production-ready Pine Script strategy for TradingView. The end goal is a fully automated algorithmic trading system that can be turned on in TradingView’s strategy tester and, once complete, be connected to a broker via alerts.

Scope
• Code a Pine Script v5 strategy that captures mean-reversion setups on my chosen symbols and time-frames.
• Include entry, stop, and take-profit rules, adaptive position sizing, and the ability to enable/disable long or short trades from the settings pane.
• Build in user-friendly inputs (e.g., look-back period, deviation thresholds, cooldown bars) so I can fine-tune without editing code.
• Plot clear on-chart signals and statistics: entry/exit markers, position lines, cumulative PnL, and drawdown.
• Generate alert conditions for every order action so I can forward them to my broker.

Acceptance criteria
1. Strategy compiles in Pine Script v5 with no errors or security warnings.
2. Backtest on at least one symbol/time-frame matches the logic I describe and produces trades consistent with the plotted signals.
3. All inputs and alerts function as expected and can be toggled in the settings.
4. Source code is clean, commented, and delivered as a .pine file.

Please reply with a brief outline of how you would structure the script, any clarifying questions you have about the mean-reversion rules, and an estimated turnaround time.
