How to Convert Pine Script to MQL4 for MetaTrader 4


If you’re a trader who uses TradingView’s Pine Script for your strategies but want to automate them on MetaTrader 4 (MT4), you might be wondering: Can Pine Script be converted to MQL4? How, then, can the process be done successfully? This article presents you with everything in simple terms: and also, it introduces a very useful tool — MetaConnector — that eases conversion and automation.


What are Pine Script and MQL4?

Pine Script is TradingView's proprietary language used for writing custom indicators and trading strategies. It enjoys much popularity because it's easy to use and specially designed for charting and alerts. 

MQL4 (MetaQuotes Language 4) is a language for developing Expert Advisors (EAs), custom indicators, and scripts on MetaTrader 4. It is more complex but, nevertheless, is required for automating trade on MT4.


Can Pine Script be Converted to MQL4?

The very simple answer: There is no such online direct conversion tool out there presently that can perform an automatic flawless conversion from Pine Script to MQL4. The two languages are different in syntax and structure, as well as functions and capabilities. Yet, given manual involvement or available tools, one can convert TradingView strategies into MT4.

Why cannot there be a Direct Conversion?

  • Language differences in structure: Pine Script is for charting and alerting. MQL4 is for order execution and automated trading.
  • Differences in functions: A vast number of PineScript functions have no direct equivalents in MQL4.
  • Execution environment: Pine Script is executed on the TradingView cloud whilst MQL4 is executed on your local MT4 terminal. 


How to Convert Pine Script to MQL4: Step-by-Step

1. Understand your Pine Script Strategy

Before conversion, try grasping the exact logic underlying your Pine Script, including how it calculates indicators, entry/exit conditions, and risk management. 


2. Understand Basic MQL4 Concepts

If you are unfamiliar with MQL4, begin with a basic intro to variables, functions, and order management in MT4. 


3. Manually Rewrite Pine Script Logic in MQL4

Rewrite the trading rules from Pine Script into MQL4 syntax. This requires understanding both languages well.


4. Test Your MQL4 Expert Advisor

After coding, test your EA thoroughly using MT4’s strategy tester to verify it replicates the TradingView strategy correctly.
