Pine Script Backtest And Python Extender

What This Does

The creator backtests his trend-join-long rules on MU and the Mag 7 in TradingView Pine, then hits the Pine limits and tells Claude to switch to Python to backtest across a 32-ticker watchlist over the last 30 days. Portfolio result: 54 percent win rate and a positive total P&L that Pine couldn't produce.

What You Get

• Pine Script strategy from natural language
• TradingView backtest metrics (P&L, drawdown, profit factor)
• Python fallback for large watchlists
• per-ticker P&L breakdown
• top-10 winners table

Customize

• watchlist: list of tickers
• period: how many days back to test
• timeframe: 5m, 15m, 1d
• capital: starting equity
• per_trade_risk: percent risked per trade

Sample Output

Backtest returns 14 trades on MU with total P&L of 1,200 dollars, profit factor 2.48, then Python rerun on 32 tickers returns 54 percent win rate over 30 days.

Target Audience

Systematic traders needing repeatable multi-ticker backtests
