Basics of MQL4 Programming

MQL4 uses a procedural programming model, which means that you write a series of instructions that the program follows in order. Here are some of the basic programming constructs you need to know:

Data types and variables

Variables are used to store data in MQL4. It supports various data types, including:

  1. int: Integer values
  2. double: Floating-point values with double precision
  3. bool: Boolean values (true or false)
  4. string: Character strings
  5. datetime: Date and time values
  6. color: Color values (used for graphical objects and indicators)

Variables can be declared as either global (accessible throughout the entire script) or local (accessible only within the function they are declared in). Constants are also supported, which are variables whose values cannot be changed during the program’s execution. Here is an example of how to declare a variable:

int x = 10;
double y = 1.2345;
bool z = true;
string s = "Hello World!";

Arrays

Arrays are used to store a collection of data in MQL4. They can be of different data types such as integer, double, bool, and string. Here is an example of how to declare an array:

int numbers[5] = {1, 2, 3, 4, 5};

Control Structures and Operators

Arithmetic, comparison, and logical operators

MQL4 supports various operators for performing calculations and making decisions. Here are some of the common operators:

// Arithmetic operators:
+   Addition
-   Subtraction
*   Multiplication
/   Division
%   Modulo

// Comparison operators:
==  Equality
!=  Inequality
<   Less than
>   Greater than
<=  Less than or equal to
>=  Greater than or equal to

// Logical operators:
&&  Logical AND
||  Logical OR
!   Logical NOT

Conditional Statements

Conditional statements are used to execute different sets of instructions based on a certain condition. MQL4 has two types of conditional statements: if-else and switch-case.

  1. if: Used for making decisions based on specific conditions. An ‘if’ statement checks a condition and executes a block of code if the condition is true.
  2. else: Used in conjunction with ‘if’ to provide alternative code execution when the condition is false.
  3. switch: Allows multiple conditions to be checked and corresponding code blocks to be executed based on the evaluated conditions.

Here is an example of an if-else statement:

if (x > 5) {
    Print("x is greater than 5");
} else {
    Print("x is less than or equal to 5");
}

Loops

Loops are used to execute a set of instructions repeatedly. MQL4 has two types of loops: for and while.

  1. for: A loop that iterates a specific number of times, typically used when the number of iterations is known in advance.
  2. while: Creates a loop that repeats a block of code as long as a specified condition is true.

Here is an example of a for loop:

for (int i = 0; i < 10; i++) {
    Print(i);
}

Functions and built-in functions

Functions are blocks of code that perform specific tasks and can be called multiple times throughout a script. MQL4 has many built-in functions that perform various tasks, such as opening and closing orders, accessing price data, or calculating indicator values.

Users can also create custom functions for specific tasks or to simplify their code. Custom functions can be called just like built-in functions and can be reused across different scripts or projects. Here is an example of how to declare and call a function:

// Function declaration
void PrintMessage(string message) {
    Print(message);
}
// Function call
PrintMessage("Hello World!");

Structure of MQL4 scripts

An MQL4 script consists of event handlers and functions. The main event handlers are OnInit, OnDeinit, and OnTick for EAs, and OnCalculate for custom indicators.

  1. OnInit: This event handler is called when a script, EA, or custom indicator is initialized. It is used for setting up variables, loading resources, and performing other initialization tasks.
  2. OnDeinit: This event handler is called when a script, EA, or custom indicator is removed from the chart or when the platform is closed. It is used for releasing resources, closing files, and performing cleanup tasks.
  3. OnTick: This event handler is specific to EAs and is called every time a new price tick is received. It is the main function where trading algorithms are implemented and executed.
  4. OnCalculate: This event handler is specific to custom indicators and is called every time the indicator needs to be recalculated.

Time and Date Management in MQL4

Datetime data type and functions

Datetime is a data type used for storing date and time values in MQL4. Some essential functions for working with datetime include:

  1. TimeCurrent(): Returns the current server time.
  2. TimeLocal(): Returns the current local time of the computer running the platform.
  3. TimeToStr(): Converts a datetime value to a string representation.
  4. StrToTime(): Converts a string representation of date and time to a datetime value.

Working with timeframes and periods

In MQL4, timeframes are represented by predefined constants, such as PERIOD_M1 for 1-minute charts, PERIOD_H4 for 4-hour charts, and PERIOD_D1 for daily charts. These constants can be used when accessing historical price data or when applying indicators to different timeframes.

Handling Prices and Orders

Accessing price data

Price data can be accessed using several built-in MQL4 functions, such as:

  1. Bid: The current bid price for a symbol.
  2. Ask: The current ask price for a symbol.
  3. High[], Low[], Open[], Close[]: Arrays containing historical high, low, open, and close prices for a specific symbol and timeframe.

Understanding order types and their functions

There are several order types in MQL4, including:

  1. Market orders: Buy or sell orders executed immediately at the current market price.
  2. Limit orders: Buy or sell orders executed when the market price reaches a specified limit price.
  3. Stop orders: Buy or sell orders executed when the market price reaches a specified stop price.

Managing orders with MQL4 functions

MQL4 provides various functions for managing orders, such as:

  1. OrderSend(): Sends a request to open a new order.
  2. OrderModify(): Modifies an existing order, such as changing stop loss or take profit levels.
  3. OrderClose(): Closes an existing order.
  4. OrderCloseBy(): Closes an open order by another opposite order.

void OnInit() {
    // Set the indicator buffers
    SetIndexBuffer(0, MyBuffer, INDICATOR_DATA);
}
  1. Define the OnCalculate() function, which is called on every tick of the market to calculate the indicator values. Here is an example:
void OnCalculate(const int rates_total, const int prev_calculated, const datetime &time[],
                  const double &open[], const double &high[], const double &low[], const double &close[],
                  const long &tick_volume[], const long &volume[], const int &spread[]) {
    // Calculate the indicator values
    for (int i = prev_calculated; i < rates_total; i++) {
        MyBuffer[i] = iMA(NULL, 0, Period, 0, MODE_EMA, PRICE_CLOSE, i + Shift);
    }
}
  1. Compile the indicator by clicking on “Compile” in the menu bar or pressing F7.
  2. Test the indicator by attaching it to a chart and observing its behavior. Make sure to test it thoroughly in a demo account before using it in a live account.

input double LotSize = 0.1;
input double StopLoss = 50;
input double TakeProfit = 100;
  1. Define the OnInit() function, which is called when the EA is initialized. Here is an example:
void OnInit() {
    // Print a message when the EA is initialized
    Print("EA initialized");
}
  1. Define the OnTick() function, which is called on every tick of the market. Here is an example:
void OnTick() {
    // Get the current bid and ask prices
    double bid = SymbolInfoDouble(_Symbol, SYMBOL_BID);
    double ask = SymbolInfoDouble(_Symbol, SYMBOL_ASK);
    // Place a buy order if the current bid price is below the last closed price
    if (bid < iClose(_Symbol, PERIOD_CURRENT, 1)) {
        OrderSend(_Symbol, OP_BUY, LotSize, ask, 0, StopLoss, TakeProfit, "My EA", MagicNumber, 0, Green);
    }
}
  1. Compile the EA by clicking on “Compile” in the menu bar or pressing F7.
  2. Test the EA by attaching it to a chart and observing its behavior. Make sure to test it thoroughly in a demo account before using it in a live account.

Backtesting and optimizing EAs in MetaTrader 4

Before deploying an EA in a live trading environment, it is crucial to backtest and optimize it using historical data. This is done through the Strategy Tester in MetaTrader 4, which simulates trading over a specified period and provides detailed performance statistics. The optimization process involves adjusting the input parameters of the EA to find the most profitable combination.

Scripts and Libraries

Purpose and creation of scripts

Scripts are MQL4 programs that perform a single action, such as closing all open orders, calculating position size, or downloading historical data. Unlike Expert Advisors, scripts do not run continuously and are executed only once when they are applied to a chart. To create a script, open the MetaEditor from MetaTrader 4, create a new file, and choose ‘Script’ as the template. Write your code within the OnStart event handler and compile the script.

Importing and using libraries for code reusability

Libraries are MQL4 files that contain reusable functions and can be imported into other MQL4 programs, such as Expert Advisors, custom indicators, or scripts. By creating libraries, users can save time and effort when coding similar functions across multiple projects. To create a library, open the MetaEditor, create a new file, and choose ‘Include’ as the template. Write your custom functions and save the file with a .mqh extension. To use the library in another MQL4 program, add an ‘#include’ directive at the beginning of the file, followed by the library file name in double quotes.

Debugging, Optimization, and Best Practices

Debugging techniques in MQL4

Debugging is an essential aspect of programming, as it helps identify and resolve errors in the code. Some common debugging techniques in MQL4 include:

  1. Print(): Use the Print() function to display messages or variable values in the ‘Journal’ or ‘Experts’ tab of the Terminal window. This can help track the program’s progress and identify potential issues.
  2. Comment(): The Comment() function can be used to display messages or variable values directly on the chart. This is useful for visualizing real-time changes in variables or calculations.
  3. Breakpoints: Breakpoints can be set in the MetaEditor to pause the program’s execution at specific lines of code. This allows you to examine the values of variables and the program flow to identify issues.
  4. Debugging Mode: The debugging mode allows you to step through your code line by line and observe its behavior. To enable debugging mode, click on “Debug” in the menu bar and select “Start Debugging” or press F5.

Optimizing your Expert Advisor

Optimizing an Expert Advisor involves fine-tuning its input parameters to maximize performance and profitability. MetaTrader 4’s Strategy Tester provides an optimization feature that allows you to test various combinations of input parameters and identify the most profitable settings. Keep in mind that over-optimization can lead to curve-fitting, which reduces the EA’s ability to adapt to changing market conditions.

Security measures and best practices

  1. Account information protection: Avoid hardcoding sensitive information, such as account numbers or passwords, in your MQL4 code. Instead, use input variables or external files to store and retrieve sensitive data.
  2. Error handling: Implement error handling in your MQL4 code to manage unexpected situations gracefully. Use GetLastError() to retrieve error codes and create appropriate responses to address them.
  3. Code readability and organization: Write well-structured, commented code to improve readability and maintainability. Organize your code using functions, separate files for different modules, or libraries for reusable functions.
  4. Regular updates and maintenance: Periodically review and update your MQL4 programs to ensure they remain compatible with MetaTrader 4 updates and adapt to changing market conditions. Also, keep up with the latest MQL4 development news, best practices, and community discussions.
