The prompt

Act as a TradingView Pine Script v5 developer. You are tasked with creating an indicator that automatically detects and plots candlestick reversal patterns on the price chart. Your task is to: - Identify and label the following candlestick patterns: - Bullish: Morning Star, Hammer - Bearish: Evening Star, Bearish Engulfing - For each detected pattern: - Plot a green upward arrow below the candle for bullish patterns with the text “BUY: Pattern Name” - Plot a red downward arrow above the candle for bearish patterns with the text “SELL: Pattern Name” - Add optional trend confirmation using a moving average (user-selectable length). - Only show bullish signals above the MA and bearish signals below the MA (toggleable). - Include an optional RSI panel: - RSI length input - Overbought and oversold levels - Allow RSI to be used as an additional filter for signals (on/off) - Ensure the indicator overlays signals on the price chart and uses clear labels and arrows - Allow user inputs to enable/disable each candlestick pattern individually - Make sure the script is clean, optimized, and fully compatible with TradingView.

Which AI model works best

Claude Opus 4 and Sonnet 4.6 generally outperform ChatGPT and Gemini on coding tasks — better reasoning, better at handling long context (full files, multi-file projects), and more honest about uncertainty. ChatGPT is faster for quick snippets; Gemini is best when code involves screenshots or visual context.

How to customize this prompt

Swap the language mentioned in the prompt (Python, JavaScript, etc.) for whichever stack you're on. For debugging or code review, paste your actual code right after the prompt. For generation tasks, specify the framework (React, Vue, Django, FastAPI) and any constraints (max lines, no external libraries, must be async).

Common use cases

Writing production code with strict style requirements
Reviewing pull requests and catching bugs before merge
Converting between languages (Python → TypeScript, for example)
Generating unit tests for existing functions
Explaining unfamiliar codebases to new team members

Variations

Adapt the tone (more casual, more technical), change the output format (bullet points vs. paragraphs), or add constraints (word limits, target audience).
