PAMM and MAM accounts let you hand money to a trader who manages it alongside other people's, with profit and loss split by how much each person put in. They sit somewhere between running your own account and buying a signal: your money stays at a broker, but someone else pulls the trigger. The arrangement can work honestly, and it can also be a tidy way to lose money to a manager whose record you never actually checked.
What they are
PAMM stands for Percentage Allocation Management Module. Several investors' funds are pooled into one trading account, a manager trades the pool, and profit or loss is allocated back to each investor by their share of it. Put in 10% of the capital and you take 10% of the gain — or 10% of the loss.
MAM stands for Multi-Account Manager. The idea is similar but the plumbing is different. The manager trades a master account and the trades are copied across separate sub-accounts, with the allocation set per sub-account rather than by one flat percentage. That flexibility lets a manager run different risk levels for different investors from the same signals.
How they work
You open an account with a broker that offers PAMM or MAM, deposit funds, and link them to a manager you have chosen from the broker's list. The manager places trades on the master account and the broker's software allocates or mirrors them to yours.
The fees are where it gets expensive. Most managers charge a performance fee — a cut of any profit, often 20% to 30% — and some add a flat management fee on the capital itself. A fair setup uses a high-water mark, so the manager only earns a performance fee on new profit, not twice on the same gains after a loss and recovery. While your money is allocated you usually cannot place your own trades, and you can normally only withdraw at set rollover points rather than on demand.
How they differ from copy trading
Copy trading mirrors another trader's positions into your own account, which stays under your control, and you can switch the signal off whenever you like. PAMM is more committed: your money is pooled with everyone else's and the manager controls the lot. MAM keeps the sub-accounts separate but the manager is still the one trading. In both cases you are handing over far more day-to-day control than a copy-trading follower ever does.
The risks and red flags
The allocation maths is the fair part. The risk lives entirely in two places: the manager and the broker.
- You give up control. The manager decides position size, risk and when to cut a loss. If they blow up, you blow up with them.
- Fees compound against you. A 30% performance fee plus a management fee can turn a decent year into a mediocre one.
- The record must be verified. A screenshot of a huge month proves nothing. You want live, read-only history covering a drawdown, not a highlight reel.
- Pooled money attracts fraud. Some "PAMM" offers are Ponzi structures paying old investors with new deposits, run through anonymous offshore brokers.
Treat guaranteed returns, no verifiable history, and pressure to deposit quickly as reasons to walk away.
Why it matters
Whether a PAMM or MAM is sensible comes down to the person and the platform, not the label. A regulated broker offering PAMM is a different proposition from an unnamed one promising 10% a month. Before you allocate a penny, check the manager's real results the way you would check any signal: look at the maximum drawdown, not the profit line alone, and confirm the history is genuine rather than a picture. Handing over control is not the problem. Handing it over blind is.
The Karnek note
If you are weighing up a PAMM or MAM manager, the one thing worth doing first is verifying their real trading, not the marketing. Karnek reads live performance straight from a MetaTrader terminal, read-only, so you can see the genuine equity curve and drawdown before you allocate. It can never place trades or touch the account — it only watches. That does not make a manager trustworthy, but it does stop a screenshot from doing the talking.
