Introduction to Expert MQL4/5
Expert MQL4/5 is a framework within MetaTrader platforms (MT4 and MT5) designed for developing algorithmic trading strategies. These are often referred to as Expert Advisors (EAs) and allow users to automate trades based on predefined rules. Experts are written using the MQL (MetaQuotes Language), a C-like programming language tailored for trading operations, such as handling orders, analyzing market data, and executing trades without human intervention. Expert MQL4/5 is crucial for traders looking to automate complex trading strategies, manage multiple accounts, and even integrate external APIs or libraries for more sophisticated operations, such as market sentiment analysis or machine learning models. For example, an EA in MQL4 could be designed to automatically open a buy position whenever the price crosses above a moving average and close it when the price drops below it, while managing the lot sizes, stop loss, and take-profit levels. In MetaTrader 5 (MQL5), additional features like working with multi-currency strategies or performing more complex backtesting can be implemented.
Main Functions of Expert MQL4/5
Trade Management
ExampleAn EA can monitor market conditions and automatically open or close trades based on predefined rules. For example, if the price breaks a certain resistance level, the EA opens a buy trade with a specified lot size, stop-loss, and take-profit.
ScenarioIn a breakout trading system, an EA can place a buy order when the market price exceeds a resistance level, and a stop-loss is set below the support level. It continuously monitors the price, adjusting orders as necessary without human intervention.
Market Analysis
ExampleMQL5 allows creating custom indicators to perform in-depth market analysis. For example, an EA could calculate a moving average crossover and send a signal when short-term averages cross long-term averages.
ScenarioA trend-following EA uses moving averages to determine market direction. When the 50-period moving average crosses above the 200-period moving average, it signals a bullish market, prompting the EA to open a buy position.
Interfacing with External Libraries
ExampleThrough MQL4/5, developers can integrate DLLs or APIs like `wininet.dll` for internet connectivity or `kernel32.dll` for file operations.
ScenarioA developer may use the `wininet.dll` library to fetch real-time data from an external API, such as news headlines, and adjust the trading strategy dynamically. If negative news about a currency pair is detected, the EA might close all open trades for that currency.
Ideal Users of Expert MQL4/5
Algorithmic Traders
This group includes professional and semi-professional traders who aim to automate their trading strategies. These users benefit from MQL4/5 by automating repetitive tasks, optimizing strategies through backtesting, and reducing the emotional biases in decision-making.
Developers/Programmers
Software developers with an interest in financial markets can use MQL4/5 to create complex EAs or custom indicators. Their technical expertise allows them to leverage MQL’s programming capabilities for building sophisticated trading solutions, including multi-strategy systems, arbitrage EAs, and integration with external data sources or APIs.

Install MetaTrader and MetaEditor
Ensure you have MetaTrader 4 or 5 along with MetaEditor to create, edit, and run your Expert Advisor (EA) scripts efficiently.
Set up the development environment
In MetaEditor, create a new EA or script. You'll need to define the basic structure including functions like `init()`, `deinit()`, and `start()` for MQL4 or `OnInit()`, `OnTick()`, and `OnDeinit()` for MQL5.
Code your logic and compile
Use MQL4/5 to code your algorithm, handling orders, market conditions, and other logic. Compile the script to check for errors.
Backtest and deploy
Test your EA with historical data to ensure it functions as expected. Once satisfied, run it live on a MetaTrader terminal.
