PAMM and managed accounts — how they work and the catch

Krzysztof had thirty thousand zloty saved and zero time for charts, so he did what half the internet advertises — he paid his capital into a PAMM account run by a manager with an impressive leaderboard. For four months the equity curve climbed, and in the fifth it collapsed by forty percent in a single week, because the manager averaged into a losing position with heavy leverage. Krzysztof could do nothing — he had no view of the trades and no right to close them. This is not a story about bad luck, but about how a managed account actually works and where its catches are hidden.

What a PAMM account actually is

PAMM stands for Percentage Allocation Management Module. In practice it is a shared pool of money: many investors pay their capital into one account, and an appointed manager (also called the master) trades the whole balance as if it were a single large portfolio. You place no orders — your job ends with choosing a manager and paying in. Everything else happens without your involvement.

The allocation mechanism is the heart of it. Suppose ten people are in the pool and your contribution is ten percent of the total. If the manager produces a positive result over a period, ten percent of that profit goes to you. If the pool loses money, ten percent of the loss is yours as well. That is the fundamental difference from a deposit or a bond: in a PAMM there is no guaranteed capital, and a fall in the account value flows through to your balance in proportion to your share. The broker supplies only the technical allocation infrastructure; it takes no responsibility for the manager trading result.

How the profit and loss split works in practice

Numbers show it best. The example below is hypothetical and only illustrates the mechanics — it promises no result of any kind.

You pay 30,000 zloty into a pool whose total capital is 300,000 zloty, so your share is exactly ten percent. After a month the manager closes the period with a positive result of 60,000 zloty across the whole pool. Your gross share of the profit is 6,000 zloty. Now the performance fee applies: if the manager charges thirty percent, you hand back 1,800 zloty, leaving 4,200 zloty in your pocket. Had that same month ended with a loss of 60,000 zloty on the pool, your balance would have dropped by 6,000 zloty — and here the manager takes nothing, because there is nothing to take. The fee applies only to profit, but the loss is entirely yours, in proportion to your share.

That asymmetry is the core of the problem. The manager works for a share of your profits, but does not share your losses zloty for zloty. So they carry a built-in temptation to take more risk — more leverage means more potential profit for them, while in a blow-up it is mainly your capital that melts. The reward mechanism and the risk mechanism are not symmetric.

PAMM, MAM, LAMM and copy trading — how they differ

Several related terms orbit PAMM. LAMM (Lot Allocation Management Module) copies position size in lots — when the manager opens one lot, your account receives a one-lot position regardless of how much capital you hold. MAM (Multi-Account Manager) is a more flexible layer in which the broker allows allocation by various methods, including percentage and lot-based. All three share the same trait: one person makes the decisions for many.

Copy trading sits close by, and I covered it in detail in the article on copy trading services and how to vet the trader you copy. The difference is subtle but important. In copy trading, positions are mirrored on your own account, which you can see fully and disconnect at any moment. In a PAMM, your funds go into a shared pool under the manager control, and you do not see the individual trades. The deeper the delegation of decisions and the smaller your control, the closer you get to portfolio management in the legal sense — and that has consequences I will turn to shortly.

Where exactly is the catch?

There are several catches, and it is worth breaking them apart. The first is loss of control: you hand every trading decision to a stranger and cannot stop it midway. The second is the track record, which guarantees nothing — PAMM leaderboards suffer from survivorship bias, because managers who blew up the pool simply drop off the list, leaving only those with a temporarily pretty curve. The third is leverage: the manager can trade with a level of gearing that turns an ordinary drawdown into a disaster, a trap I laid out more broadly in the piece on 1:500 leverage as a trap.

"The miracle of compounding returns is overwhelmed by the tyranny of compounding costs." — John C. Bogle, *Common Sense on Mutual Funds*, John Wiley & Sons, 1999.

The fourth catch is exactly those costs. A performance fee of twenty to fifty percent, charged on a recurring basis, can over the long run eat most of the manager edge over the plain market. The fifth is the liquidity of your money: many offers carry withdrawal windows and lock-up periods, so capital can be unavailable precisely when you would most want to pull it — in the middle of a deep drawdown. None of these catches is theory; each has played out on the accounts of real investors.

Why the manager licence is the decisive issue

This is the most serious catch, because it touches the law. Discretionary management of other people money in financial instruments is a licensed activity. In Poland it is supervised by the Polish Financial Supervision Authority (KNF), and across the European Union it is regulated by the MiFID II directive — providing investment services, including portfolio management, requires authorisation as an investment firm. Yet a large share of the PAMM managers advertising on social media hold no licence at all.

That is a double problem. First, the legal one: you entrust money to someone carrying out a regulated activity without authorisation, hence outside supervision and outside any complaints procedure. Second, it is a classic scam vector — an unsupervised pool you pay into but do not control is an ideal vehicle for siphoning capital away. How to recognise these signals is something I broke down in the article on spotting a scam broker in five minutes. The broader regulatory layer that governs who may manage client money sits in the regulations section on forexmechanics.com, and you can verify any entity status yourself before committing a cent.

What to do before you pay in a single euro

The verdict is simple: a PAMM account is a high-risk instrument that demands heavy due diligence rather than blind faith in a leaderboard. Treat any promise of a guaranteed return as a warning sign, because on an honest market nobody guarantees a trading result. The steps below you can take today.

1. Check the manager and platform licence in the register. Open the KNF public warnings list and the register of investment firms, type in the exact entity name, and confirm it holds authorisation to manage money. If the name is absent from the register or appears on the warnings list, do not pay in a cent — keep looking elsewhere.
2. Calculate the full cost of the performance fee on your own example. Take the real rate from the offer and work out what you keep from a hypothetical profit after the fee is deducted, then repeat the calculation for a loss scenario. The numbers will show you plainly that the risk is yours while the reward is shared.
3. Read the terms for withdrawals and maximum drawdown. Find the frequency of withdrawal windows, the lock-up periods and the manager historical maximum drawdown. If the largest fall in equity exceeds the level you can genuinely tolerate emotionally and financially, this offer is not for you, whatever the headline return.
4. Compare PAMM with an alternative you control. Set the offer against an account where you make the decisions yourself, using the 2026 broker selection checklist and an understanding of how the ECN and market maker models affect costs. Sometimes the cheapest and safest option is simply keeping control of your own capital.
