MetaTrader 4: A Beginner's Guide

Updated October 23, 2026

MetaTrader 4 is a free trading platform released in 2005 by MetaQuotes Software. It became the industry standard for retail forex, and its interface, order types and automation model are still what most brokers build around. Updated September 2026.

MT4 or MT5

This question comes first because it affects everything else. MetaQuotes has directed development toward MT5 for years, and new brokers are steered toward it.

MT4 remains widely supported and heavily used, largely because of inertia: an enormous library of expert advisors and custom indicators exists for it, and MQL4 code does not run on MT5 without rewriting.

The practical guidance: if you are starting fresh, MT5 offers more timeframes, more order types and ongoing development. If you rely on existing MQL4 tools, MT4 remains the sensible choice. Check which your chosen broker supports before committing either way.

What MetaTrader 4 does

MT4 is an electronic trading platform connecting to your broker's servers. It displays live pricing, executes orders, and provides the charting and analysis tools for making decisions.

How does MetaTrader 4 work?

• User-friendly interface designed for beginners as well as experienced traders

• A range of financial instruments, depending on what the broker offers

• Real-time market data streamed from the broker

• Charts and technical analysis tools, including a large indicator library

• Automated trading through expert advisors

The platform itself is free. It is supplied by whichever broker you open an account with, and the broker determines what instruments, spreads and execution you receive through it.

Setting it up

• Choose a broker that offers MT4 and is regulated in your jurisdiction

• Open an account, which is usually completed online in a few minutes

• Download the MT4 software from the broker or from MetaQuotes

• Install it following the standard setup process

• Log in with the account details supplied by the broker

Most brokers provide demo credentials alongside the live account, so the platform can be tested with virtual funds before depositing anything.

The four windows

The interface is organised around four panels, and understanding what each does covers most of what a beginner needs.

Market Watch lists every instrument available on your account with live bid and ask prices. This is where you select what to trade and where you can see the current spread on each pair.

Navigator gives access to your accounts, indicators, expert advisors and scripts. Custom indicators and automated systems are installed and launched from here.

Charts displays price action with whatever indicators and drawing tools you apply. Multiple charts can be open simultaneously across different instruments and timeframes.

Toolbox shows your open positions, pending orders, account history, alerts and the platform journal. This is where you check what you actually hold and what it is currently worth.

Order types

MT4 supports market orders for immediate execution and four pending order types: buy limit, sell limit, buy stop and sell stop, each triggering at a specified price.

Stop loss and take profit levels attach to any position, and trailing stops adjust automatically as price moves in your favour.

Set the stop loss when you open the position rather than intending to add it later. A position without a stop depends on you being present and disciplined at exactly the moment both are hardest.

Automated trading

Expert advisors are programs written in MQL4 that execute trades according to defined rules. They can be purchased, downloaded or written, and the strategy tester allows backtesting against historical data before live use.

Two cautions. Backtest results are routinely optimised to fit historical data and then fail on live prices, so treat a perfect backtest curve as a warning rather than a recommendation. And an expert advisor bought from a vendor is only as honest as the vendor: ask for the maximum historical drawdown, not the return figure.

Strengths and limitations

• Strengths: free, widely supported, huge library of indicators and expert advisors, stable and familiar

• Strengths: available on desktop, web and mobile with consistent behaviour

• Limitations: fewer timeframes and order types than MT5

• Limitations: development focus has moved to MT5, so new features arrive there

• Limitations: the trading conditions you get depend on the broker, not on the platform

That last point matters most. MT4 is identical across brokers, so the spread, execution speed and regulatory protection come entirely from who you open the account with. Compare regulated options in our forex brokers section and see related trading guides.

MetaTrader 4: frequently asked questions

Is MetaTrader 4 free?

Yes. The platform is supplied free by your broker, who determines the spreads, execution and instruments available through it.

How to use MetaTrader 4?

Should I use MT4 or MT5?

MT5 if starting fresh, since it has more timeframes and order types and ongoing development. MT4 if you depend on existing MQL4 indicators or expert advisors, which do not run on MT5.
