Why Your MetaTrader Account Will Not Connect to a Copier

When a MetaTrader account will not connect to a signal copier, the cause is almost always one of the three things you typed: the server, the password, or the login. The rest of the time it is something your broker did to the account.

A copier logs in to your broker the same way your MetaTrader terminal does, with a login number, a password, and a server name. If the terminal would be refused with those details, so will the copier. That gives you a simple test for nearly everything below: open MetaTrader, go to File → Login to Trade Account, and type exactly what you gave the copier.

Here are the causes in the order I would check them, with what TTMT shows for each.

The server name is wrong

Brokers run many servers, and their names differ by a digit: a Live01 and a Live02, a Demo and a Demo-2. Your account lives on exactly one of them. Pick the neighbor and the broker has no record of your login there.

Check it yourself. Open your MT4 or MT5 app and look under Settings or About. It shows the exact server your account is on. Copy it character for character. Your broker's welcome email has it too, but accounts get moved between servers, so the app is the better source.

What TTMT shows. When you add an account you search the broker list by name and pick the matching server. If your broker's server is not in the list, TTMT tells you the server is not in its directory and asks for a server file, a .srv file from your broker's MT4 or MT5 install folder or from their support team. Upload it and the connection carries on from there. If you picked a server that exists but is not yours, the attempt ends in an authentication failure, because the broker refused a login it does not hold on that server.

You used the investor password

Every MetaTrader account has two passwords. The trading password (some brokers call it the master password) can place and manage orders. The investor password is read-only: it lets someone watch the account and nothing else. Brokers usually send both in the same welcome email, which is how the wrong one ends up in the form.

Check it yourself. Log in to MetaTrader with the password you gave the copier and try to open a new order. With the investor password, trading is disabled in the terminal.

What TTMT shows. A "Read Only" error means you entered the investor password. Switch to the trading password. A copier has to place orders, so there is no version of this that works with read-only access.

While you are on the password: paste it straight from the broker email and check for a space at the start or the end. Passwords are case-sensitive, and a trailing space copied out of an email is invisible.

The login is not your account number

A MetaTrader login is the account number. It is digits only, something like 12345678. It is not the email address you use for your broker's client portal, and it is not your username on their website.

Check it yourself. The number is in your broker's welcome email, and in MetaTrader under File → Login to Trade Account.

What TTMT shows. The account number field checks what you type before anything is sent. If it is an email address, it says so and asks for the account number instead. It does the same for letters and for a number that is too long. The Connect button stays disabled until the field holds a number, so a login that could never work does not cost you a failed attempt at your broker.

MT4 details on an MT5 connection, or the other way round

MT4 and MT5 accounts are not interchangeable. A login issued for one platform does not exist on the other, even at the same broker with a similar server name. If you are not sure which you have, the app you normally trade in tells you. The practical differences between the two are in MT4 or MT5 for signal copying.

The broker expired or disabled the account

Demo accounts often expire after a few weeks, and a broker can close or disable an account for its own reasons. From the copier's side these all look the same at first: the details were right last month and are refused today.

Check it yourself. Log in from MetaTrader. If the terminal cannot log in with details that used to work, the account is the problem, and only your broker can tell you whether it is expired, closed, or disabled.

What TTMT shows. When your broker reports the account as disabled, TTMT says "Account Disabled" and tells you to contact the broker to reactivate it. There is nothing to change on our side until they do.

The broker wants something a copier cannot give

Some refusals are about the account's security settings, and the fix is in MetaTrader or at the broker.

If you have already tried several times

Two messages show up after repeated attempts, and both are worth reading slowly.

"Too Many Attempts." Your broker rejected the details several times, so further checks on that account are paused for a while. The pause applies to the account, not to the password you typed. Correcting the password and retrying straight away meets the same pause, and every rejected attempt counts against the same limit. When we are told how long the pause lasts, TTMT shows that time. When no time is shown, we do not have one, and I would rather show nothing than a number we made up. Fix the details first, wait, then make one attempt.

"No Answer Yet." Connecting involves your broker validating the login, and that can take minutes. A normal connection takes one to three. When no verdict comes back in time, TTMT says exactly that and does not name a cause it did not observe. Many attempts that end this way turn out to be a wrong password, server, or platform, so re-check your details before trying again. Do not submit a second time while the first is still showing progress, because that starts a second attempt and can trigger the pause above.

When the broker refuses an account that was already connected

This is the version that catches people out. The account connected fine months ago, then the broker expired a password or closed a demo, and the login starts being refused in the background.

A stale password reads as credentials invalid, with a strip on the account that takes you to the password change. You update the credentials in place. Your channel routing, your settings, and your trade history stay attached to the account, so there is no disconnect-and-rebuild. The details are in changing your broker password without losing your setup.

An account that keeps failing to connect is not retried in a tight loop. TTMT spaces its attempts further apart the longer the failure lasts. Once the failure has gone on long enough with the market open, the account shows as disconnected, and a signal routed to it is not sent. It fails with a reason that names the account as not connected. Nothing is placed, and that signal is not sent again later. On a signal that goes to several accounts, the others trade as normal and the one that could not connect is listed by name.

At that point TTMT knows the account cannot connect. It does not know why, and it does not pretend to. The checks are the ones above: are the login details still right, and is the account still open at the broker?

The docs have the full list on the connection issues page, and your broker password never reaches us covers how the credentials are handled once they are in.
