Paste a Pine script, watch it plot on your chart.

  2. 02

    Select target language

    Choose one target language or select 'All' to generate five outputs simultaneously.

  3. 03

    Add to chart or copy

How accurate is the conversion?
Standard indicators (MA, RSI, MACD, Bollinger) come out copy-paste ready. Platform-specific features are flagged with warnings for manual review.
Is my code sent to a server?
Conversion runs entirely in your browser. Only saving to My Indicators stores the script in your account.
Can I convert strategies, not just indicators?
The converter focuses on indicator logic. Order execution code is platform-specific and gets flagged for manual porting.
Which plan do I need?
5 conversions a month are free. Pro and Premium are unlimited.
