Copy trades between accounts you own, across brokers
One master, several followers, different brokers: which password each login needs, how every follower gets its own size, and what changes when one of them is a funded account.
To copy trades between accounts you own, you connect every account to one copier, name one of them the master, and let the others follow it, each at its own size and under its own broker's symbol names. The accounts can sit at different brokers and on different platforms, because the copier logs into each one separately and nothing passes between the brokers themselves. CopySignals is a cloud Telegram signal copier for MT4, MT5 and eTrader: it reads the rooms you already follow through your own Telegram account and places the trades on your own broker account. The same product is an MT4 and MT5 trade copier that mirrors one of your accounts onto the rest, and that is the job this article covers.
Who needs to copy trades between accounts?
Anybody who places the same trade more than once. The common version in 2026 is a trader with a personal account at one broker and two or three funded accounts from prop firms. Every entry is typed three or four times, every stop is moved three or four times, and the account you got to last has a worse price than the first. A second version is a trader who splits money across two brokers on purpose, so that one broker's outage or one bad fill is not the whole book. A third is somebody moving from an old MT4 account to a new MT5 one who wants the new account to shadow the old one for a few weeks first.
All of these are one person with several logins. That is a different thing from following a stranger's account on a social trading network, and the difference is laid out in our piece on copy trading, social trading and signals. Here the master is you.
How does copying between accounts work?
The copier holds a logged-in session on every account, watches the master for changes and repeats each change on the followers. A new position on the master becomes a new position on each follower. A moved stop is moved. A partial close is a partial close, at the follower's size. A full close ends it everywhere.
Two things make this harder than it sounds. The first is that the followers are not copies of the master. They have different balances, different minimum lots, sometimes a different name for gold. So each follower carries its own settings and the copier translates the trade, it does not clone it. The second is that a follower at another broker gets that broker's price at the moment its order arrives, not the master's fill. On a quiet market the gap is nothing. Around a news release it can be several pips. MetaCopier's documentation describes a setting for exactly this: "Slippage occurs when a trade is executed at a different price than expected", with the limit entered in points. On CopySignals the matching guards are a maximum spread and an optional delay before placing, set per copier. Whatever product you use, expect the followers' results to track the master's closely and never exactly.
Which password does each account need?
A follower always needs the trading password, because the copier has to place orders on it. MetaQuotes' help page for MetaTrader 5 explains the two kinds of access: "Logging in using the master password gives full rights for working with the account", while "Investor authorization allows you to see the account status, analyze prices, and work with your own Expert Advisors, but not trade". A copier only has to read the master, so some vendors accept the investor password on that side. Social Trader Tools says so in its FAQ: lead accounts "can be added using the investor password", and follower accounts "require full trading credentials (login + trader password)".
On CopySignals you connect each account with its broker server, login and trading password, and any connected account can then be the master or a follower. The copier can place, modify and close orders on the accounts you connected and can do nothing else. We are not a broker and we never hold your funds. You are still handing a vendor a credential that can trade, ours or anybody's, so read the terms first and change the password when you stop using the service.
Can the accounts be at different brokers and on different platforms?
Yes, with a copier built for it, and the cloud products all say so on their own sites. Duplikium's home page lists all MT4 and MT5 brokers, followed by a run of other platforms. MetaCopier's says it "lets you copy trades across all major trading platforms and crypto exchanges". Social Trader Tools describes its account manager as covering "unlimited MT4 and MT5 accounts from any broker". CopySignals connects MT4, MT5 and eTrader accounts, and one master can feed followers on all three at once.
That list is also our limit. If one of your accounts is on any other platform, CopySignals cannot connect it, and Duplikium or MetaCopier, whose sites list more platforms, is the place to look for that setup. If every account you own is on MT4, MT5 or eTrader, the platform question is settled and what is left is the settings. One of them belongs to MT5 alone: whether the account is hedging or netting. Social Trader Tools states that it does not support MT5 netting accounts, and the reason why that matters to any copier is in our article on copying from MT4 to MT5.
How should each follower be sized?
Per follower, never once for the whole group. A personal account with a small balance and a large funded account should not trade the same lot, and the funded one usually has a daily loss limit the personal one does not. Social Trader Tools puts the principle in one line: "Each follower account can have its own risk settings, including risk by balance, risk by equity, lot multiplier and fixed lot size". Duplikium's support centre lists its own options, from Auto Risk, where "the Slave trade size is proportional to the Master trade size and the Master account size", to a fixed size where "whatever the Master trade size is, each trade placed on the Slave account will be the defined Fixed lot or Fixed Unit value".
CopySignals gives every follower four choices: a fixed lot, a multiple of the master's lot, the master's lot scaled by the ratio of the balances, or a percent of the follower's account measured against the trade's stop. Each is capped by a maximum lot, and the cap is the field to fill in first. For accounts of similar size a multiplier of 1 is enough. When the balances differ a lot, the balance ratio keeps the risk roughly level without any arithmetic from you. For a funded account with a strict loss limit, percent of the account is the safer pick, because it holds the risk per trade steady whatever the master is doing.
What about prop firm accounts?
Check the firm's rules before you connect anything, because the software will not check them for you. Social Trader Tools is blunt about it: "it is your responsibility to confirm that your firm's terms permit the use of a trade copier before connecting your account". Duplikium's home page says its master and slave management is "Compliant with Prop Firm rules!", which is a claim about the tool, not a reading of your contract. Firms differ on copying between your own accounts, on copying across firms, and on how many accounts one person may run the same trades on.
Where it is allowed, the clean setup is your personal account as the master and the funded accounts as followers, each with its own size, its own maximum lot and a cap on open positions. The settings a funded account needs are covered in our article on prop firm accounts.
Where does the copier run while you sleep?
Either on your machine or on the vendor's. A copier built as an expert advisor lives inside your own terminals, so every terminal has to stay open and connected, which in practice means renting a VPS. A cloud copier keeps the sessions for you. Duplikium describes itself as "Based on the Cloud. No copy trading software or tools to install, no PC to run, and no VPS to pay", and MetaCopier says it "runs entirely in the cloud and does not require a VPS or any software installation". CopySignals works the same way: we run one MetaTrader terminal per connected account on our own servers, and eTrader accounts are driven through eTrader's copytrading API. The trade-offs of the two designs are compared in our comparison of cloud and desktop copiers.
Setting it up on CopySignals
- Connect every account you want in the group, each with its broker server, login and trading password.
- Create a copier and choose the account you actually trade on as the source. That account is the master.
- Add the other accounts as targets. On each one set the maximum lot, then the sizing method.
- Compare each follower broker's symbol names with the master's. Add renames, a prefix or a suffix where they differ, and restrict the instrument list if only some symbols should be mirrored.
- Set a maximum spread and a cap on open positions. Leave reverse copy off unless you mean it.
- Point the copier at a demo follower for a day and read the event log. A trade that was skipped is listed there with the reason.
If a Telegram room also feeds the master through CopySignals, those trades reach the followers like any other position on the master.
What it costs
The plan is decided by how many trading accounts you connect, master included. Starter is $14 a month, Basic is $29 and Pro is $149, with Business by email above that. Every plan is the whole product, so account to account copying is not an add-on. Billing is monthly by card or crypto, you can cancel any time, and there is a 30 day money back guarantee. The account counts per plan are on the pricing page.
A copier repeats the master's decisions on every follower, the losing ones as well, so a bad day is multiplied by the number of accounts. Trading carries risk with or without one. Start with one follower on demo, keep the maximum lot low, and add the funded accounts after a week of logs you have read.
