PAMM vs MAM vs trade copier: which one fits you
PAMM pools money under a manager, MAM mirrors a manager into separate accounts, and a trade copier repeats trades across accounts you own. What each one means for control and size.
PAMM pools investors' money into one account that a manager trades. MAM keeps every investor in a separate account and mirrors the manager's trades into each one. A trade copier does the mirroring too, but you run it yourself, on accounts that stay yours. 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, so one of your accounts can lead and the others follow.
The three get confused because they look alike from outside: one person trades, other accounts show the same positions. The differences are who holds the money, who sets the size, and who can walk away without asking anyone. Those decide which one fits you.
What is the difference between PAMM, MAM and a trade copier?
PAMM and MAM are broker-side products for a money manager and their investors. A trade copier is software you point at accounts you own. The first two need a broker that offers them and a manager who accepts you. The third needs only the accounts.
The definitions below come from two broker pages. ATFX describes PAMM as a solution that "allows investors to allocate funds to a manager who trades on their behalf", and MAM as a platform where a master trader "manages multiple accounts from a single interface". B2Broker is more specific in its PAMM versus MAM article: in PAMM the platform consolidates investor accounts into a master account that the money manager trades, and profit and loss are distributed in proportion to each investor's share of equity.
How does a PAMM account work?
A PAMM account works as a pool. Investors put money in, the manager trades the pool as one account, and the result is split by each investor's share. According to B2Broker, the system distributes profit and loss in proportion to each investor's share of equity at execution time.
B2Broker adds that PAMM allocation is proportional only, and that PAMM withdrawals require recalculating the whole pool's equity shares.
ATFX adds that in PAMM the investor can view their own account and monitor the manager's performance, and that fees depend on the manager's terms. Its page gives no figures, and we do not state any.
How does a MAM account work?
A MAM account gives each investor a separate account and lets the manager trade all of them from one screen. B2Broker says a MAM system gives the manager the same one-screen execution as PAMM while keeping every investor legally separate, each with its own balance, margin and risk profile.
The sizing is configurable per account. B2Broker lists fixed-lot allocation, risk percentage and custom formulas as allocation methods, and says MAM allows differentiated stop-loss levels, lot size limits and leverage caps for each sub-account. It also says MAM withdrawals are simpler because the accounts stay independent.
The visibility is where ATFX is cautious: its page says MAM investors have "limited access to view information about their individual sub-accounts". If you want to see everything the manager does on your account, check what your broker's MAM actually shows before you fund it.
Where does a trade copier fit?
A trade copier fits when you are the one deciding. You trade a master account, or follow a Telegram room, and the software repeats it on every account you connect. Nobody manages your money, and no manager sits between you and your balance.
In CopySignals the master can be a Telegram room or one of your own trading accounts. When it is an account, its positions are mirrored to every other account at that account's own size, across brokers and across MT4, MT5 and eTrader. We cover the mechanics in master and follower accounts. The sizing is set by you, per account: a fixed lot, a percent of the account measured against the signal's own stop, a multiple of the master's lot, or the master's lot scaled by balance. A maximum lot always caps them. See fixed lot against risk percent and proportional sizing for how those behave.
What a copier does not do is give you a manager. CopySignals is not a broker, not a signal seller and not a money manager, it gives no advice, and it holds no funds. It can only place, modify and close orders on accounts you connected. If you want somebody else to decide what to trade, the copier is not that, and a PAMM or MAM offer from a broker is closer to it.

|---|---|---|---|
| PAMM | One pooled master account that the manager trades | Profit and loss split in proportion to each investor's share of equity | B2Broker |
| MAM | Each investor keeps a separate account, legally separate | Allocation configurable per account: fixed lot, risk percentage or custom formulas | B2Broker |

| CopySignals | Your own accounts at your own brokers, on MT4, MT5 or eTrader | You choose per account: fixed lot, percent of account, multiple of the master lot or balance scaled, with a maximum lot | CopySignals |
Which one should you use?
Use PAMM or MAM when you want a manager to trade for you and your broker offers it. Use a trade copier when you want to keep the decisions and spread them over more than one account. That is the usual case for a trader with a prop firm account and a personal one who wants the same trade at two sizes, which we walk through in funded and personal account on the same signal.
The two are not exclusive in principle, but they answer different questions. PAMM and MAM answer "who trades my money". A copier answers "how do I get this trade onto all my accounts". If your question is the second one, the broker products add a manager you did not need.
Three limits are worth stating. CopySignals supports MT4, MT5 and eTrader only, so an account on any other platform cannot be connected. It cannot pool money, because every account stays separate and in your name. And copying amplifies whatever the master does, in both directions. Trading carries risk, and a copier repeats a loss as faithfully as a win.
Can I copy to a friend's or client's account?
Only to accounts that you can connect, and the arrangement between you and the other account holder is yours to sort out. We are software, not a manager, and we cannot hold or move anyone's money. If you are managing other people's money, check what your local rules require before you do it; that question is for a lawyer, not a copier.
What does it cost?
Every CopySignals plan includes the whole product and differs only in how many trading accounts and Telegram accounts it covers. Starter is $14 a month, Basic $29, Pro $149, and Business is by email for more. Payment is by card or crypto, monthly, cancel any time, with a 30 day money back guarantee. Details are on the pricing page. For several accounts at once, one signal to many accounts shows the setup, and copying between brokers covers the mixed-broker case.
If you want to try account to account copying, connect a demo master and one follower and read the event log before you go live.
