What is a .MQH file?
An MQH file is a type of file used by MetaTrader, which is a platform for online trading. This file is known as a MetaTrader Include File. It is used to store definitions for common variables and functions. These definitions are helpful for programmers who are developing custom indicators, Expert Advisors (which are automated trading systems), and scripts for trading.
The MQH file serves a similar purpose to .H files in other programming environments. It allows programmers to write functions and variables once and then use them in multiple other source files. This is useful because it saves time and helps maintain consistency across different parts of a program. Additionally, MQH files can be shared among programmers to use common functions without needing to share the entire source code.
To open an MQH file, you typically use the MetaEditor, which is a tool included with the MetaTrader software. MetaEditor allows you to edit and manage Expert Advisors, custom indicators, and scripts. The location of MQH files is usually linked to the location of .MQ4 or .MQ5 source files. For instance, if the source file is in the /Libraries directory, the corresponding MQH file will be found in the /Include directory.
MetaTrader, the software that uses MQH files, is primarily used for trading and analyzing Forex, stocks, CFDs, and futures. It includes various technical analysis tools and supports automated trading systems and copy trading. This makes it a comprehensive tool for traders looking to automate their trading strategies and analyze financial markets.
In summary, MQH files are essential for developers using the MetaTrader platform to create and manage custom trading tools and strategies. These files help in organizing and reusing code efficiently within the trading platform environment.
