With Metaquotes Programming, you can turn your trading ideas into reality. Want to buy when the price goes up? No problem. Want to sell when it goes down? Easy peasy. You can even get fancy and create your own indicators or use complex algorithms to make smarter trading decisions.
Whether you're a seasoned trader looking to optimize your strategies or a complete beginner eager to dive into the world of finance, Metaquotes Programming has something for everyone. So, what are you waiting for? Let's start coding and turn your trading dreams into reality!
Syntax Overview
Metaquotes Language (MQL) is the programming language used in MetaTrader platforms for developing trading strategies, indicators, and other automated trading tools. There are two main versions of MQL: MQL4 and MQL5. Here's an overview of the syntax and some code examples in both languages:
Syntax Overview:
- MQL is similar to C/C++ in terms of syntax, making it relatively easy to learn.
- Statements end with a semicolon (;), and blocks of code are enclosed in curly braces ({ }).
- Comments can be added using double slashes (//) for single-line comments or / / for multi-line comments.
- Variables must be declared with a data type before use, and the scope of variables can be global or local.
- Functions are used to encapsulate blocks of code, and predefined functions are available for common tasks like getting price data or placing trades.
- Control structures such as if-else statements, loops (for, while), and switch-case statements are used for decision-making and iteration.
- Operators like arithmetic operators (+, -, *, /), comparison operators (==, !=, <, >), and logical operators (&&, ||, !) are used for calculations and comparisons.
- Preprocessor directives, identified by a hash symbol (#), are used for including libraries, defining constants, and configuring the EA.
Code Examples
MQL4 Example: // This is a simple MQL4 script to print "Hello, World!" to the console
// Include the standard library for input/output functions
#include <stdio.mqh>
// Entry point of the script
void ()
{
// Print "Hello, World!" to the console
Print("Hello, World!");
}
MQL5 Example: // This is a simple MQL5 script to print "Hello, World!" to the console
// Entry point of the script
void ()
{
// Print "Hello, World!" to the console
Print("Hello, World!");
} Note: In MQL5, there is no need to include a separate library for standard input/output functions; they are built into the language.
Key Functions and Concepts:
- OnInit(): Function called when the EA is initialized.
- OnStart(): Function called when the EA is started or a new tick is received.
- OnTick(): Function called on every tick (price change).
- OrderSend(): Function to send trading orders (buy/sell).
- iMA(): Function to calculate Moving Averages.
- NormalizeDouble(): Function to round numbers to a specified number of digits.
- Print(): Function to print messages to the terminal/console.
- datetime: Data type for representing date and time.
- double, int, bool, string: Data types for numbers, integers, logical values, and strings respectively.
These examples and concepts provide a glimpse into the syntax and functionality of Metaquotes Language. As you delve deeper into MQL4 or MQL5, you'll discover a wealth of features and possibilities for creating powerful automated trading strategies and indicators.

Algo Trading : Metaquotes 2 - Understanding Metaquotes
Discover the basics of Algorithmic Trading with Metaquotes in this introductory guide. Learn how to get started, understand key concepts, and explore the benefits of automated trading. Perfect for beginners! #AlgoTrading #Metaquotes #AutomatedTrading
Welcome to our comprehensive guide on Metaquotes Programming! If you've ever wondered about automating your trading strategies or exploring the world of algorithmic trading on the MetaTrader platform, you've come to the right place.
In this series, make a journey through the fascinating realm of Metaquotes Language 4 (MQL4) and its successor, MQL5, developed by Metaquotes Software. These languages serve as the backbone for creating trading robots, indicators, scripts, and other automated trading tools.
Understanding Metaquotes Programming
What is Metaquotes Programming?
Metaquotes Programming refers to the coding languages, MQL4 and MQL5, designed specifically for traders and developers to automate trading processes on the MetaTrader platform. These languages enable traders to create their own custom tools, execute trades automatically based on predefined conditions, and analyze market data efficiently.
The Importance of Automation in Trading
Traditionally, trading in financial markets involved manual execution of trades, which could be time-consuming and prone to human error. With the advent of automation through Metaquotes Programming, traders can now automate their strategies, allowing for faster execution, precise decision-making, and the ability to capitalize on market opportunities even when away from the computer.
Getting Started with Metaquotes Programming
Fundamentals of MQL4 and MQL5
It is essential to grasp the fundamentals of MQL4 and MQL5. These languages share similarities with popular programming languages like C++, making them accessible to both seasoned developers and newcomers to programming.
- Syntax and Structure: Both MQL4 and MQL5 follow a structured syntax, comprising statements, variables, functions, and control structures.
- Data Types and Variables: Understanding data types such as integers, doubles, strings, and arrays, and how to declare and manipulate variables, forms the foundation of programming in MQL4 and MQL5.
- Operators and Expressions: Learning about arithmetic, logical, and comparison operators, as well as expressions, allows traders to perform calculations and make decisions within their trading algorithms.
- Control Structures: Control structures such as loops and conditional statements (if-else) enable traders to control the flow of their programs based on specific conditions.
Differences Between MQL4 and MQL5
While MQL4 and MQL5 share many similarities, there are notable differences between the two languages. Understanding these distinctions is crucial for choosing the right language for your trading needs.
- Performance and Efficiency: MQL5 offers improved performance and efficiency compared to MQL4, making it better suited for handling complex trading algorithms and high-frequency trading strategies.
- Object-Oriented Programming (OOP): MQL5 introduces support for OOP concepts such as classes, objects, and inheritance, providing a more structured approach to coding and facilitating code reuse and maintenance.
- Compatibility: MQL4 and MQL5 are not entirely compatible with each other. While MQL5 includes backward compatibility with MQL4, certain functions and features are unique to each language.
The Versatility of Metaquotes Programming
Creating Trading Robots (Expert Advisors)
One of the primary uses of Metaquotes Programming is the creation of Expert Advisors (EAs), also known as trading robots. EAs are automated trading systems that execute trades based on predefined rules and conditions. Traders can develop EAs to implement their trading strategies, ranging from simple moving average crossovers to complex machine learning algorithms.
Developing Custom Indicators
In addition to EAs, Metaquotes Programming allows traders to develop custom indicators to analyze market data and identify trading opportunities. Whether it's a trend-following indicator, oscillators, or volatility measures, traders can leverage their programming skills to create indicators tailored to their trading strategies.
Scripting and Automation
Beyond EAs and indicators, Metaquotes Programming enables traders to automate various trading tasks using scripts. Scripts are short programs that execute specific actions on the MetaTrader platform, such as opening or closing trades, modifying orders, or performing administrative tasks. With scripting capabilities, traders can streamline their workflow and eliminate repetitive manual tasks.
Metaquotes Programming Journey
In conclusion, Metaquotes Programming offers a wealth of opportunities for traders and developers looking to automate their trading strategies and enhance their trading experience on the MetaTrader platform. Whether you're a novice trader exploring algorithmic trading for the first time or an experienced developer seeking to optimize your trading algorithms, mastering MQL4 and MQL5 opens the door to endless possibilities in the world of automated trading.
Throughout this series, learn Metaquotes Programming, covering everything from advanced techniques to practical examples and real-world applications. So, stay tuned as we embark on this exciting journey together, unlocking the full potential of Metaquotes Programming and revolutionizing your approach to trading.
