MT5 weighed against the connection

Exness MT5 download when data is scarce: the heavier terminal, and when it still costs less

MT5 asks the connection for more than MT4 does — more chart periods to fill, a deeper set of instruments to quote, and an order book that updates while it is on screen. And yet on some machines it is the route that puts the least traffic through the line all day. Both halves of that are below, along with the installer itself, which comes from the official Exness website and downloads without any login.

The honest half of the answer

Three places MT5 asks the line for more than MT4

A newer terminal is a wider terminal, and width has a data cost. It is small once a chart has settled, and noticeable in the first minutes after a fresh install.

More chart periods to fill

MT5 carries 21 chart timeframes against nine in MT4. Each period a chart is switched to is a stretch of history the terminal may not hold yet, so exploring the intermediate periods early on means repeated requests for bars — until they are stored on the disk and stop travelling.

More built-in tools to feed

Thirty-eight built-in indicators come with the terminal against 30 in MT4. The maths runs on the local machine and costs the connection nothing; what costs is the history each added indicator wants underneath it before it can draw.

An order book is a stream, not a page

Depth of market — the list of pending buy and sell orders waiting near the current price — is one of the additions over MT4. While that window is open it updates continuously, which makes it the most talkative thing on the screen. Closing it ends that stream instantly.

Trading is risky and will not suit every reader. A terminal that draws more on screen does not make an outcome more predictable.

Platform specifications are published by the platform developer and by Exness and may change with new releases.

The other half

Why the bigger terminal is often the smaller bill

The comparison that matters on a scarce connection is not MT5 against MT4. It is an installed program against a browser tab, and this is the point where MT5 changes the arithmetic on machines MT4 cannot reach at all.

The official MT4 desktop package exists for Windows only. On macOS and on Linux the fallback has been the Web Terminal — a full trading session inside a browser tab, with nothing to install. Nothing to install also means nothing kept: every reload fetches the interface again, and a flaky line reloads often.

MT5 is published with official macOS and Linux packages as well as the Windows one. On those machines it converts a route that re-fetches itself into a route that arrived once and stays — which is why the heavier terminal ends the week having asked the connection for less, even though its first day asked for more.

On Windows the same logic applies against leaving the browser terminal open all day. Whether that trade is worth making depends entirely on how the connection behaves, not on which platform is newer.

Install once, keep the file

The Windows, macOS and Linux packages all come from the official exness.com and download without logging in; the same links are listed inside the Personal Area. Keeping the downloaded package means a later reinstall costs nothing on the line.

Sign-in is text, not traffic

MT5 connects with three short items: the trading account number, the trading password and the server name. The number and server are shown in the Personal Area; the password is set when the account is created and reset there if lost.

Same account, different traffic

What each MT5 route asks the connection to carry

One MT5 account can be reached three ways. They differ far less in what they can do than in what has to travel the line to do it.

	MT5 Desktop terminal	WEB Browser terminal	APP MT5 mobile
Arrives	Once, as an installer for Windows, macOS or Linux	Never stored — the page is built again on each visit	Once, from the App Store or Google Play
After a reload or restart	Sign-in and the bars missed while closed	The whole interface again, then the sign-in	Sign-in and the bars missed while closed
Stored history	Kept on the disk between sessions	Kept only while the tab lives	Kept on the device between sessions

How much any of this weighs in practice depends on the network, not on the broker. Every platform route side by side — back to the platform matrix.

The first hour after installing

Filling in history without flooding the line

A freshly installed terminal knows no history at all. Everything it draws in the first session has to be requested, and the order in which that happens is entirely under local control.

Start with one chart, not a screen full

Each open chart pulls its own bars. Opening a single instrument and letting it finish drawing before adding a second spreads the requests out instead of stacking them on a connection that cannot take them at once.
Pick the period before scrolling backwards

Switching a chart between the 21 available periods asks for a different set of bars each time. Choosing the period the strategy actually uses, then scrolling, avoids paying for history on periods that will never be looked at again.
Trim the instrument list

Instruments left visible are quoted continuously whether or not anyone is watching them. Removing the ones that are not being traded is the quietest single change available inside the terminal.
Open depth of market only when it is being read

The order book is useful precisely because it never stands still, and that is also its cost. It is a window to open for a decision and close afterwards, rather than one to leave running beside the charts.

What a break does not undo

Downloaded bars stay downloaded. History already stored on the disk is read locally after a reconnect; the terminal only asks for the stretch it missed.
The account is on the server. Open positions and pending orders sit behind the account number rather than inside the program, which is why the same account looks the same in the desktop terminal and in the mobile app.
A silent send is not a placed order. If no confirmation came back, the position list after reconnecting is the thing to read before repeating the instruction.

Before any of it matters

The account decides which terminal is even an option

Trading accounts at Exness are opened for a specific platform inside the Personal Area, so the installer on this page needs an MT5 account behind it — real or demo. An MT4 account will not sign in here, and no amount of bandwidth changes that.

A demo MT5 account with virtual funds can be opened right after registration, before any deposit, and carries the same market prices as a real one. On an expensive connection it is also an inexpensive way to find out how the terminal behaves on that particular line before anything is at stake. The Exness Trade app is a further door to the same MT5-based accounts and is covered in the mobile guide.

Trading is risky and may not be suitable for everyone.

Quick answers

MT5 and a scarce connection: frequently asked questions

Does MT5 use more data than MT4?

It asks for more history, because there are 21 chart periods to fill against nine, 38 built-in indicators against 30, and an order book that updates while open. Once the charts in daily use have been drawn, the ongoing difference comes down to how many instruments are being quoted, which is a local setting on either terminal.

Is the MT5 download free?

The installer is published on the official Exness website and downloads without payment or login, on Windows, macOS and Linux alike. Whatever the connection itself charges to carry it is the only cost involved at that stage.

On a poor connection, is the browser terminal a better idea than installing?

Usually the opposite. The Web Terminal keeps nothing between visits, so a reload fetches the interface again — and unstable lines produce a lot of reloads. An installed terminal pays that cost once. The browser route wins when installing is impossible or the machine is not the reader's own.

Does MT5 run on macOS and Linux without a Windows machine?

Yes — official MT5 packages exist for macOS and for Linux, published by the platform developer, so neither system is pushed into the browser. This is the practical reason MT5 can end up carrying less traffic than MT4 on those machines: MT4 has no desktop package there at all.

What happens if the connection drops mid-session?

The chart stops updating and the terminal tries to reconnect. Positions and pending orders are held on the server behind the account number, so they are unaffected by the local link; history already stored stays stored, and only the missed stretch is requested again.

Which password does MT5 want?

The trading password, set when the trading account is created and reset in the Personal Area if forgotten. It is not the email password used for the Personal Area itself. Along with it MT5 needs the account number and the exact server name, both shown in the Personal Area.

Can an MT4 account be used in MT5 to avoid a second install?

No. Accounts are opened for one platform or the other, and an MT4 account signs in only to MT4. Opening an MT5 account alongside it in the same Personal Area costs nothing on the connection — it is a form, not a download.

Is a demo account enough to test how the terminal behaves on a weak line?

For the connection question, yes: a demo MT5 account streams the same market prices as a real one, so the traffic behaves the same way. It is opened in the Personal Area with virtual funds and no money at risk. Demo account guide →

The installer waits; the account is the slow part

The account is a web form on the official Exness website — an email address, a short set of questions, an identity check completed in the Personal Area afterwards — and it is the one step here that asks the connection for almost nothing. The heavy transfer is the package; the choice that makes the package worth transferring is picking MT5 when the trading account is created. Full registration walkthrough →
