Three products, one marketing word
Copy trading, PAMM and MAM get used interchangeably and describe quite different arrangements. In signal copying, your account mirrors another trader's positions proportionally; you keep control and can close anything at any time. In a PAMM structure, your money joins a pool the manager trades as one account, and profits and losses are allocated by share — you do not hold the positions and cannot close them. In MAM, a manager trades your own account under a limited power of attorney, allocating trades across many accounts at once.
The difference matters most when things go wrong. A copied position can be closed by you in seconds. A PAMM share can usually only be redeemed at a rollover point defined in the manager's terms, which may be weekly or monthly, and a bad week is not something you can step out of on Tuesday. Brokers rarely spell this out, and clients frequently discover which product they bought at the worst moment.
Before copying anyone, check these four things
- Maximum drawdown, not just return — a 300% gain with an 80% drawdown is a martingale about to fail.
- Track record length: anything under a year has not seen enough market conditions to mean much.
- How the strategy provider is paid — from profit, or from the volume they generate.
- Whether you can exit instantly, or only at a defined redemption point.
What the published track records leave out
Copy-trading platforms rank strategy providers by return, because that is what attracts followers. The statistics that predict whether a strategy survives are different ones: maximum drawdown, the ratio of average win to average loss, and whether position size grows after losses. A grid or martingale system produces a beautiful equity curve for months and then gives everything back in a single session, and on a leaderboard sorted by return it sits at the top until the day it does.
Survivorship bias does the rest of the damage. Strategies that blow up disappear from the rankings, so the visible population is the subset that has not failed yet. A leaderboard is not a sample of what copy trading achieves; it is a sample of what has not yet stopped working. Reading drawdown first, and treating any record under twelve months as insufficient, filters out most of what is wrong with the format.
Copying does not transfer responsibility
Losses in a copied account are yours. The strategy provider is not your fiduciary, is typically not licensed to give advice, and in most arrangements is paid whether you profit or not. Regulators have taken action against brokers presenting copy trading as advice — treat it as a self-directed decision to allocate money to someone else's execution.
Fee structures and misaligned incentives
How the provider gets paid determines what they will do. A performance fee charged on new profit above a high-water mark aligns them with you reasonably well: they earn when you earn, and a drawdown must be recovered before they earn again. A share of the spread or a per-lot rebate does not: the provider is paid for volume, so a strategy that trades constantly pays better than one that waits, regardless of outcome.
The second structure is common precisely because it is invisible to the follower — it comes out of the trading cost rather than as a line on a statement. Where a broker publishes its copy-trading fee model explicitly, as NAGA does with its copy-trading fees, that disclosure is worth weighting. Where the model is not stated, assume volume-based and read the strategy's trade frequency accordingly.
Common questions about copy trading
Is copy trading a good way to start?
It is a way to have exposure without learning, which is not the same thing. It teaches nothing about position sizing or risk, and it removes the feedback loop that makes a trader improve. As an allocation decision for part of a portfolio it is defensible; as an alternative to learning it is not.
What return should I expect?
Nobody can answer that honestly, and any platform that suggests a figure is marketing. What can be said is that consistent double-digit monthly returns in the leaderboards are almost always leverage and martingale sizing rather than skill, and they end the same way.
Can I lose more than I allocate?
In a copy or PAMM arrangement with negative balance protection, no. Without it — on an offshore entity — a severe gap can theoretically take an account below zero. Check that the entity provides it before allocating.
What is the difference between PAMM and MAM for me?
PAMM pools your money with others and allocates results by share, with redemption at defined points. MAM keeps the money in your own account with a manager trading it, so you retain visibility and usually the ability to revoke access. MAM gives more control; PAMM is simpler to run at scale.
