Python to Pine Script converters are tools designed to help traders and developers translate trading algorithms and indicators written in Python into Pine Script, the native language of TradingView. This conversion enables users to deploy their Python-based strategies directly on TradingView charts, expanding their trading toolkit and automation capabilities.

Why Use a Python to Pine Script Converter?​

The Best Pine Script Generator
  • TradingView Integration: Pine Script is the only scripting language supported by TradingView, a leading platform for charting and strategy testing. Converting Python code to Pine Script allows seamless use of strategies on TradingView.
  • Leverage Python's Power: Python offers extensive libraries for data analysis and machine learning, which are often used to develop advanced trading strategies. Conversion lets you bring these sophisticated models onto TradingView.
  • Automation and Backtesting: Pine Script enables real-time strategy execution and backtesting within TradingView, which is valuable for traders refining their approaches.

Challenges in Conversion​

Converting Python code, especially complex libraries like those involving wavelet transforms (e.g., pywt), to Pine Script is challenging due to Pine Script's limited functionality and lack of support for certain Python libraries and C extensions. Automated tools may introduce errors, so manual review is often necessary.

Available Tools and Approaches​

Pyine​

Pyine is a Python package designed to convert Pine Script code into Python, supporting variable declarations, if statements, alerts, and common indicators like moving averages. While it primarily converts Pine Script to Python, understanding its structure can assist in manual conversion efforts.

Pynescript​

Pynescript allows parsing Pine Script into an Abstract Syntax Tree (AST) and converting it back, making analysis and partial automation of conversion tasks easier.

PyneSys​

PyneSys offers a Pine Script to Python converter that translates Pine Script into Python code using the PyneCore library. It provides API and CLI tools for easy integration and supports various subscription plans for different usage levels. This tool focuses on preserving Pine Script semantics in Python, but it is not a direct Python to Pine Script converter.

AI-Assisted Conversion​

Generative AI tools like ChatGPT and Google Bard can help in converting Pine Script strategies into Python and vice versa, but be careful as automated conversions may contain errors and need validation.

Best Practices for Conversion​

  • Understand Both Languages: Gain a solid grasp of Pine Script structure and Python equivalents, including libraries like pandas, ta-lib, and matplotlib for indicators and data manipulation.
  • Manual Adjustments: Automated tools rarely produce perfect results; manual coding and testing are essential.
  • Use Appropriate Libraries: Replace Pine Script functions with Python libraries when converting to Python, or simplify Python logic to fit Pine Script's capabilities when converting the other way.
  • Test Thoroughly: Validate the converted code by comparing outputs and behavior with the original script.
