Do you want to know the differences between MQL4 and EX4 programming languages? MQL4 is a language for creating trading robots and Expert Advisors. EX4 is an executable file made from compiled MQL4 code. Let’s look at them both and see how they differ. We’ll also discuss the advantages of algorithmic trading and software development.
What is MQL4?
The MQL4 is a programming language used to develop trading robots or Expert Advisors. It is the language of choice for developing automated trading systems for MetaTrader 4. This programming language has functions and libraries that traders can use to create custom indicators, scripts, and other trading tools.
Expert Advisors are trading robots developed using MQL4 language to automate trading strategies in MetaTrader 4. These automated systems help traders execute trades quickly and easily, based on pre-set criteria such as market conditions and technical indicators.
Although MQL4 language is popular among algorithmic traders, it differs from EX4 – a compiled format of the code written in MQL4. The main difference between these two codes is that EX4 code cannot be easily edited or decompiled compared to source code written in MQL4.
MQL programming involves converting an indicator, script or EA from a text-based MQL format to executable file format with the extension .ex4 through compilation. To convert MQL4 to EX4, traders can either use MetaEditor – the built-in editor on MT4 or external software designed for this task.
Interestingly, when Sergey Petrov released MetaQuotes Language 2 (MQL2) in September 2002 under the name “Delta Trading,” this was an early version of what would eventually become known as MT platform – one of the most widely-used trading platforms globally for retail forex trading.
EX4 – where your code becomes an executable file and your coding tools meet their ultimate test of debugging.
What is EX4?
EX4 is an executable file created from coding tools like MetaEditor in MQL4. It contains compiled code that can be executed on the MetaTrader 4 trading platform. While MQL4 is programming language syntax used to develop trading robots, indicators, and scripts, the EX4 binary format is the final product of that programming process.
The difference between MQL4 and EX4 lies in their syntax. The former requires a source code editor like MetaEditor for coding and debugging of scripts, Expert Advisors (EAs) and Indicators while the latter is a binary code generated by compiling the source code using MetaEditor or other similar software.
It’s worth noting that the EX4 file cannot be edited once it has been compiled, but rather modifications can only be made to its original source code, which can later be recompiled into another EX4 version.
If you’re looking to convert MQL4 to EX4, there are two methods you can consider: using MetaEditor or external software tools. In the first method, open your MQL file in MetaEditor and hit “Compile” to generate an EX4 file. Using external tools involves decompiling your MQL source code in a different language then making changes before re-compiling it back into EX4.
When converting MQL4 to EX4 with external software tools, best practices include:
- desisting from copyright infringement by confirming usage rights of any files used;
- avoiding errors during extraction – always ensure necessary headers are included;
- regularly backing up code when working with new versions (testing-phase);
- safeguarding sensitive data by switching off web-platform variables when uploading files online.
To avoid mistakes during conversion, errors inevitably happen due to human error but executing consistent checks will ensure they stay at a minimum level. Ensure all variables are handled appropriately; include comments on grammar and punctuation; finally check for bugs by testing indicators manually.
Overall if you wish to start developing custom indicators for MetaTrader4 i.e MQL4 coding, it’s critical to have a basic understanding of the differences between MQL4 ad EX4 file formats and how to convert one into the other. Failing to do so could lead to a frustrating and time-consuming process of trial-and-error with your code not functioning properly during installations or trading platforms malfunctioning in their entirety.
Algorithmic trading got you confused? Here’s the difference between MQL4 and EX4 in a nutshell.
Differences between MQL4 and EX4
MQL4 and EX4 are two programming languages used for algorithmic trading software development. The two languages have significant differences in their syntax, compiling process, and file extensions, among others.
To understand the differences between MQL4 and EX4 better, below is a table highlighting their main differences:
|Human-Readable Source Code
|Access to Source Code by End-Users
|Automatic Compilation from the MetaEditor
|High (Source code open)
|Low (Source code unavailable)
Although both programming languages share many similarities – including structure – there are some unique details that require special consideration while converting the code.
For software developers using external software to convert their MQL4 codes into EX4 codes must decompile their MQL codes before making any changes. Then afterward, they can modify the decompiled code with their preferred IDE. After completing all amendments on the source files, they can then compile the modified code back to EX4 using command line compilers like GCC or Clang.
Pro Tip: When converting from MQL4 to EX4, it’s essential to keep best coding practices in mind. Proper comments should be included explaining each step within the program to ensure that anyone who needs to read your code can easily understand what’s going on.
