A Beginner's Guide to MetaTrader 4 Web

MetaTrader 4 web is a version of the MetaTrader 4 terminal that runs inside a web browser. Like the desktop and mobile editions, it is developed by the software company MetaQuotes and made available to clients by brokers who license it. KaltraPrime does not supply MetaTrader or any trading terminal; this module explains how the software works so you can use it, or evaluate it, with open eyes.

How the software fits between you and the market

MetaTrader is a front end. It displays prices, sends orders and shows your positions, but the prices and the execution come from the provider's trading server. Each broker runs its own server, sets its own instruments, spreads, contract sizes and trading hours, and decides how orders are handled. Two people using the same MetaTrader software with different providers can see different prices and receive different fills.

That is why the software's reputation says nothing about the firm behind a particular server. The checks in the broker module still apply in full.

Using MetaTrader 4 online: what the browser terminal offers

Running MetaTrader 4 online through a browser removes installation, which is useful on a shared or locked-down computer, or on an operating system where the desktop program is awkward to run. A typical web terminal includes:

• Market watch listing the provider's instruments with bid and ask prices.
• Charts in the standard nine timeframes, from one minute to monthly, as bar, candle or line views.
• Built-in indicators such as moving averages, oscillators and volume tools, plus basic drawing objects like trend lines.
• Order entry for market orders and the four MT4 pending types: buy limit, sell limit, buy stop and sell stop, each with optional stop-loss and take-profit.
• Account panels showing balance, equity, used and free margin, and margin level.

Logging in uses the account number, password and server name issued by your provider. A demo login from the same provider lets you practise with the same instruments and conditions without real money.

Limits of the web version

The web terminal is lighter than the desktop program. In general it does not run Expert Advisors (automated strategies), custom indicators or scripts written in MQL4, and its range of analysis tools is narrower. Some chart settings and templates may not carry over between devices. Traders who rely on automation or custom tools use the desktop version, often on a remote server, and treat the web terminal as a way to check and manage positions while away from their main computer.

MetaTrader 4 or MetaTrader 5?

MetaTrader 5 is a separate platform from the same developer, not an upgrade of MT4. It supports more timeframes and order types, a depth-of-market view and a different programming language, and it is often used for exchange-traded instruments as well as forex and CFDs. MetaTrader web access is also available for MT5, with similar limits relative to its desktop version. Strategies and indicators written for one platform do not run on the other without being rewritten.

A quick tour of an order ticket

Suppose you are studying a EUR/USD setup on a demo account. The order window asks for volume in lots, the order type, and optional stop-loss and take-profit prices. With 0.10 lots selected, each pip is worth $1, so a stop 25 pips away means about $25 at risk before spread and slippage; the lot size calculator does this arithmetic for any balance and stop. After the order fills, the trade tab shows its running profit, and the account panel shows how much margin it uses, which you can cross-check with the margin calculator.

Fake terminals and how to avoid them

Because MetaTrader is familiar, scammers imitate it. Some run fraudulent servers that clients reach through genuine-looking software; others build lookalike websites or apps branded as a MetaTrader web terminal. The display looks real while the "profits" are invented.

• Reach the terminal through the provider's own site, after confirming that site on the regulator's register.
• Check that the server name in the login screen matches the provider you verified.
• Be wary of anyone who sends you a direct link to a terminal or asks you to install software through a messaging app.

The wider pattern is described in our scam module.

Setting up a practice workspace

A clean layout makes the terminal easier to read. Keep the market watch limited to the handful of instruments you actually study, open one chart per instrument on the timeframe you analyse, and add only the indicators you understand. Check the contract specification for each instrument, which lists the lot size, pip or point value, trading hours and financing rates the provider applies; these can differ from the defaults you expect. If you use a demo, set the balance to an amount similar to what you would really deposit, so the position sizes you practise are realistic.

Security habits in a browser

• Use the terminal only on a device and network you trust, and log out when you finish, especially on shared computers.
• Do not let the browser store the trading password on machines other people use.
• Enable any additional login protection your provider offers for its client area.
• Bookmark the provider's official site after verifying it, rather than following links from emails or messages.

Web, desktop or mobile?

Many traders use all three: the desktop terminal for analysis and any automation, the mobile app for alerts and quick checks, and the browser version when working from a computer where installing software is not possible. Positions and orders are held on the provider's server, so they appear on every version you log in with.
