World of automated trading programming: MQL4, MQL5, and Pine Script

Hello, this is Capital Cat! MQL4, MQL5, and Pine Script are programming languages used on different trading platforms. These languages are utilized to create automated trading strategies, custom indicators, scripts, and more, but there are differences in their purposes and features. Here is a brief explanation of the characteristics and differences of each language.

MQL4 and MQL5

1. MQL4 (MetaQuotes Language 4)

   • MQL4 is a programming language developed for the MetaTrader 4 (MT4) platform.
   • It is primarily used to create automated trading (Expert Advisors), custom indicators, and scripts for the forex market.
   • MQL4 has a C-like syntax, is relatively easy to learn, and is widely accepted among forex traders.

2. MQL5 (MetaQuotes Language 5)

   • MQL5 is a programming language developed for the MetaTrader 5 (MT5) platform and is the next version of MQL4.
   • In MQL5, you can trade not only forex but also stocks, futures, options, and other instruments, allowing for a wider range of financial products.
   • MQL5 features multi-threading, native 64-bit support, and advanced built-in event handling, enabling the construction of more complex and efficient trading systems.
   • From a compatibility standpoint, MQL4 and MQL5 are not fully compatible, and to leverage the advanced features provided by MQL5, some scripts may need to be rewritten.

From personal experience when actually creating something, I felt some awkwardness in how orders are processed when taking positions and in the speed of chart events.

MQL4 remains popular because, as a programmer, MQL4 feels easier to use.

Pine Script

1. Pine Script
   • Pine Script is a programming language developed for the TradingView platform and is primarily used to create custom indicators and strategies.
   • Pine Script makes it easy for users to visualize trading strategies, and since you can apply code directly to TradingView charts, real-time data analysis and backtesting are very convenient.
   • The syntax is very simple, so even beginners can learn it relatively quickly, making it popular among a wide range of users.

　　Learning Pine Script has the advantage of being free and enabling various verifications in real time using online tools.

Summary

MQL4 and MQL5 are languages dedicated to MT4 and MT5 platforms, primarily used for developing automated trading systems. Pine Script, on the other hand, is used on TradingView and is suitable for creating indicators and simple trading strategies. Each language is a powerful tool on its respective platform, but you should choose based on the platform and your objectives.
