How to Create a Pine Script Strategy with AI: Complete 2026 Guide

What you will build by the end of this guide

A fully working Pine Script v6 strategy — EMA crossover with RSI filter, proper stop loss and take profit, position sizing, and alert wiring. You will go from a sentence describing your trading idea to a strategy running in TradingView's Strategy Tester, without writing a single line of code.

Step 1: Write a specific prompt

The quality of AI-generated Pine Script is proportional to the specificity of your prompt. Vague prompts produce generic, often incorrect strategies. Specific prompts produce production-ready code.

The prompt template that works: [Indicator combination] + [Timeframe] + [Long/Short/Both] + [Entry filter] + [Stop loss type and size] + [Take profit target] + [Position size]

// Weak prompt (produces generic, often broken output)
"Make me a trading strategy"

// Strong prompt (produces specific, compilable output)
"Pine Script v6 strategy: EMA 9/21 crossover on the 1H chart.
Long entry: EMA 9 crosses above EMA 21 AND RSI 14 is between 40 and 60.
Short entry: EMA 9 crosses below EMA 21 AND RSI 14 is between 40 and 60.
Stop loss: 1.5x ATR 14 below entry for longs, above entry for shorts.
Take profit: 3x ATR 14 in the profit direction.
Position size: 10% of equity per trade.
Include alerts for both entries."

Step 2: Review the generated code

Before injecting into TradingView, read through the generated code. Even with a specialist AI tool like TradePilot, you should understand what was built. Check these specific things:

• First line is //@version=6
• strategy() declaration has overlay=true if you want the strategy on the price chart
• All inputs use input.int() / input.float() with title= not label=
• strategy.entry() calls have direction=strategy.long or direction=strategy.short
• strategy.exit() from_entry= matches the strategy.entry() id= exactly
• Stop loss is a price level (close * (1 - pct/100)), not a raw percentage
• alertcondition() calls are at global scope, not inside if blocks

Step 3: Inject and run the backtest

With TradePilot, click the Inject button and the script is sent directly to TradingView's Pine Editor. Click Add to Chart in TradingView. If the script compiles, the Strategy Tester panel opens automatically.

If you get a compile error, click Fix in TradePilot. The error fixer reads the error message and corrects the specific line that caused it — you see a diff before accepting.

Step 4: Read the backtest results honestly

The Strategy Tester shows Net Profit, Win Rate, Profit Factor, Max Drawdown, and number of trades. Before getting excited or dismissing the results, check two things: commission is set (not 0%) and the number of trades is at least 100.

In the Strategy Tester Properties, set Commission to match your broker (0.05-0.1% for crypto) and Slippage to at least 1 tick. These two changes will significantly change the equity curve and give you realistic results.

Step 5: Iterate with the inline editor

Once you have baseline results, use TradePilot's inline editor to refine the strategy. Describe the change in plain English: 'add a volume filter — only enter when current volume is above the 20-bar average', 'make it long only', 'change the take profit to 2:1 risk-reward instead of ATR-based'.

Each change shows a diff before applying. You stay in control of every line without touching the code directly.
