The answer in three lines
- MetaTrader 4 is software licensed to brokers; it displays prices and sends orders, while the broker sets prices and holds your money.
- MT5 adds more timeframes, order types and asset classes; cTrader is an alternative from a different developer. None of them makes a broker safe.
- Get the software only through your broker's official site or the developer's official app store listing, and check the broker separately.
The MT4 platform, MetaTrader 4, is one of the most widely used pieces of retail trading software for forex and CFDs. It is made by MetaQuotes and licensed to brokers, who connect it to their own servers. That split is the single most important thing to understand about it: the software draws the charts and sends your orders, but everything that matters for your money, from the prices you see to the safety of your deposit, depends on the broker running the server.
What does MT4 actually do?
It shows charts and quotes, sends orders to your broker, manages open positions and runs automated scripts.
- Charting: nine timeframes from one minute to one month, built-in indicators and drawing tools.
- Order entry: market orders plus pending orders (buy limit, sell limit, buy stop, sell stop), with stop-loss and take-profit levels attached.
- Account view: balance, equity, margin, free margin and margin level, the numbers that decide when a close-out happens.
- Automation: Expert Advisors (EAs), programs written in the MQL4 language that can place and manage trades on their own, plus custom indicators and scripts.
- Strategy tester: a tool for running an EA over historical data.
The margin figures on the account screen use the same arithmetic as our margin calculator, and the pip values follow the pip calculator. Learning to read them before trading is more useful than learning any indicator.
Is the MT4 platform a broker?
No. It is software. The broker you log in to is the firm that sets prices, executes orders and holds your money.
When you log in, you enter an account number, a password and a server name. That server belongs to the broker. Two people using identical MT4 software with different brokers can see different prices, different spreads and different execution, and have very different levels of protection for their deposits. The software developer does not supervise brokers, and a firm offering MT4 has not been vetted by anyone because of that fact.
This matters because fraudulent firms also use professional-looking trading software, including white-label versions of well-known platforms. A familiar interface proves nothing about the firm. Check the broker using the steps in how to choose a broker.
What do the account numbers on the MT4 platform mean?
Equity is your balance plus open profit or loss; margin level is equity divided by used margin, and it decides when positions are closed.
An illustrative case: with equity of $2,000 and $1,800 of margin in use, the margin level is about 111%. Under UK and EU retail rules, the broker must start closing positions if the margin level falls to 50%, which here would mean equity dropping to $900. Free margin, equity minus used margin, is what is left to absorb losses or open new trades; in this example it is just $200. Watching the margin level, rather than the balance, is how you see a close-out coming before it happens.
How does MT4 differ from MT5?
MT5 is the newer platform, with more timeframes, order types and markets, but it is not a simple upgrade and scripts are not interchangeable.
| MetaTrader 4 | MetaTrader 5 | |
|---|---|---|
| Main focus | Forex and CFDs | Multi-asset, including exchange-traded instruments where the broker offers them |
| Timeframes | 9 | 21 |
| Pending order types | 4 | 6, adding buy stop limit and sell stop limit |
| Programming language | MQL4 | MQL5; MQL4 programs do not run unchanged |
| Extras | Basic | Depth of market, built-in economic calendar, multi-threaded strategy tester |
For a learner, the difference in daily use is smaller than the table suggests. The choice usually follows the broker: some offer only one of the two, and an account opened for one generally cannot be used on the other. If you depend on custom indicators or scripts, check that they exist for the version your broker supports before committing.
Where does cTrader fit in?
cTrader is a separate platform from a different developer, with its own interface, order handling and automation language.
cTrader is often chosen for its clean depth-of-market display, detailed order information and C#-based automation. Brokers that offer it are sometimes described as cTrader brokers, but the label only tells you which software they license. The checks on regulation, legal entity, client money and withdrawals are exactly the same as for any other firm. As with MetaTrader, a cTrader download should come from your broker's official website or the developer's official listing in a recognised app store, never from a link sent by a stranger. ZentraTrader does not distribute any trading software.
Are Expert Advisors worth the risk?
They automate rules, not profits. An EA does exactly what its code says, including losing money quickly.
Automated strategies have genuine uses: enforcing discipline, managing stops, trading rules you have tested. The problems start with commercial EAs sold with impressive back-test curves. A back-test can be tuned to fit past data almost perfectly and still fail on new prices. Spreads, slippage and requotes in live trading also differ from the tester's assumptions. Treat any EA sold with a promised monthly return the way you would treat any other promised return: as a warning sign. See how to spot trading scams.
How do you get MT4 safely?
- Choose and check the broker first, using its regulator's register.
- Follow the download link on that broker's official website, reached by typing its address, or the developer's official app store listing.
- Log in with the server name your broker gives you, and confirm it matches the broker's documentation.
- Start on a demo account to learn order entry, stop placement and the margin display.
- Never install software or connect a trading account because someone you met online told you to.
Fake trading apps imitating well-known platform names have appeared in app stores before. Check the publisher name on the listing and be suspicious of any app that asks you to deposit directly into it.
What are the common beginner mistakes on MT4?
- Confusing lots with units: 1.00 lot is 100,000 units on most currency pairs.
- Reading the chart's bid line while long positions close at the bid and shorts at the ask, which explains stops that trigger "early".
- Ignoring the margin level, which is what triggers automatic close-outs.
- Assuming demo fills will match live fills during news.
- Leaving an Expert Advisor running unattended over a weekend or news event without knowing how it handles gaps.
Follow-up questions
Is MT4 free?
The software is usually free to the trader because the broker pays the licence. You pay through the broker's spreads, commissions and other charges.
Can I use MT4 without a broker?
You can open a demo account to practise, but live trading always runs through a broker's server. The broker, not the software, holds your money.
Is MT5 better than MT4?
MT5 has more features, but many traders find MT4 sufficient. The choice usually depends on which platform your chosen broker offers and whether you rely on MQL4 programs that would need rewriting.
