Pine Script Developer: Code, Backtest & Automate My Trading Strategy (MT5/NinjaTrader Execution)

Project Overview I have a fully-defined manual trading strategy that I currently trade by hand on TradingView. I need a developer to: Code it accurately in Pine Script Backtest it to confirm historical performance (win rate, profit factor, drawdown) Set up automated execution to my broker or prop firm account (MetaTrader 5 and/or NinjaTrader), starting with paper/demo trading before going live This is NOT a request for a custom trading platform, AI integration, or a built-from-scratch execution engine. I want a lean, working pipeline using TradingView + an established webhook/bridge solution. Scope of Work 1. Strategy Coding (Pine Script v5) I will provide the exact rules: entry trigger, exit trigger, stop loss, take profit, position sizing logic, and any filters (time-of-day, trend condition, etc.) Strategy must be coded precisely to match these rules — no reinterpretation or "improvements" without checking with me first Clean, commented, editable code (not obfuscated) 2. Backtesting & Validation Backtest using TradingView's Strategy Tester on relevant instruments (e.g., NAS100, S&P 500, DAX — will confirm exact tickers/data source) Report key metrics: win rate, profit factor, max drawdown, total trades, equity curve Flag any red flags (overfitting risk, unrealistic backtest assumptions, repainting issues, look-ahead bias) If needed, recommend/run additional robustness checks (walk-forward, out-of-sample testing) 3. Execution Bridge Setup Connect TradingView alerts to my execution platform via a webhook/bridge solution (e.g., PineConnector, WebhookTrade, SignalForge for MT5; CrossTrade, Copilink for NinjaTrader — open to your recommendation based on experience) Configure alerts to fire correctly with proper JSON payloads (entry, exit, SL/TP, position size) Test thoroughly on a demo/evaluation account before enabling live execution Document the full setup so I can maintain/adjust it myself going forward 4. Handover Working, tested Pine Script strategy file Backtest report/summary Bridge configuration + step-by-step setup documentation Brief walkthrough call or video explaining how everything works What I'll Provide Complete, precise written rules for the strategy Access to my TradingView account (paid plan, webhook-capable) Details on my broker/prop firm and execution platform (MT5 or NinjaTrader) Demo/evaluation account credentials for testing Ideal Candidate Strong Pine Script v5 experience (portfolio/examples required) Prior experience setting up TradingView-to-MT5 or TradingView-to-NinjaTrader automation Understands prop firm rules around automated execution and can flag compliance concerns Can explain backtest results in plain terms, including honest caveats about overfitting or unrealistic assumptions Clear communicator, comfortable with iterative feedback
