What Is a PAMM Account? PAMM vs MAM vs Copy Trading Explained
A plain-English definition of the Percentage Allocation Management Module, how PAMM works for money managers and investors, and how it compares with MAM accounts and copy trading — plus what brokers need to offer it.
A PAMM account — short for Percentage Allocation Management Module— is a pooled money-management structure used in forex and CFD trading. Multiple investors deposit funds into a single trading account run by a professional money manager, and each investor holds a percentage share of that combined pool. The manager places trades on the pool as a whole, and every profit or loss is allocated back to each investor in proportion to their share. Investors get access to a managed strategy without placing trades themselves; the manager earns a performance fee on the gains they produce. In short, a PAMM account is a way to let one skilled trader manage many investors' capital at once, with results split automatically by ownership percentage.

What a PAMM account means
The name explains the mechanism. Percentage Allocation refers to how results are divided: by each investor's percentage of the total pool. Management Modulerefers to the software layer that sits on top of the broker's trading platform and automates the allocation. When an investor deposits into a PAMM, their capital is added to the master account and they receive a share equal to their contribution relative to everyone else's. If you supply 10% of the pool's equity, you carry 10% of its trading results — up or down.
Crucially, the money manager can trade the pooled capital but generally cannot withdraw it to themselves. The module separates trading rights from ownership of funds, which is what makes pooled management workable between strangers on a regulated broker platform.
How a PAMM account works
A PAMM account follows a repeatable cycle from allocation to distribution:
- Allocation.Investors deposit into a manager's PAMM account. Each deposit is recorded as a percentage share of the pool's total equity at that moment.
- Trading. The money manager trades the pooled capital as a single account, placing each order once rather than per investor.
- Proportional distribution.At the end of each trading period (a "rollover"), the module calculates the pool's profit or loss and assigns it to investors by their percentage share.
- Fees.The manager's agreed performance fee is deducted from each investor's profit before it is credited, and the remainder stays in the investor's balance.
- Withdrawal. Investors can typically withdraw or add capital at defined rollover points, after which the shares are recalculated.
Because allocation is proportional, every investor in a given PAMM earns the same percentage return before fees — the only thing that differs is the dollar amount, which scales with how much each person contributed.
The manager and the investor
A PAMM arrangement has two sides. The money manager is the experienced trader who runs the pooled account, sets the strategy, and takes on the trading decisions in exchange for a performance fee. A track record and transparent reporting are how a manager attracts allocations. The investoris the passive participant who supplies capital, selects a manager based on published performance and risk, and monitors results — but never places trades. This division is the core appeal: investors gain exposure to active management without needing to trade themselves, and skilled traders can scale their strategy across far more capital than they hold personally.
PAMM vs MAM vs copy trading
PAMM is one of three common managed-trading models. MAM (Multi-Account Manager) and copy trading solve a similar problem — letting people benefit from a skilled trader — but they differ in how capital is held and how much control the investor keeps. The table below summarises the differences.
| Aspect | PAMM | MAM | Copy trading |
|---|---|---|---|
| Capital structure | Pooled into one master account | Separate sub-account per investor | Each investor's own account |
| Result allocation | By percentage share of the pool | Trades mirrored into each sub-account | Signals copied into the follower's account |
| Per-investor customisation | None — everyone gets the same % | Yes — lot size, leverage, risk limits | Yes — investor sets copy size and rules |
| Who controls trading | Money manager (discretionary) | Money manager (discretionary) | Investor chooses and can stop anytime |
| Investor involvement | Passive | Passive | Self-directed |
| Best suited to | Simple pooled management at scale | Tailored risk per investor | Hands-on investors who want control |
PAMM vs MAM in more detail
PAMM and MAM are the closest of the three, and brokers often offer both. The practical distinction is pooling versus mirroring. In a PAMM, all capital sits in a single account and results are split by percentage, so it is simple to operate but gives every investor the identical proportional outcome. In a MAM, each investor keeps a separate sub-account and the manager's trades are copied into every one, allocated by a chosen method such as equal lots or a proportional-by-equity rule. That separation lets a MAM apply different lot sizing, leverage, or risk settings per investor— useful when clients have different risk appetites or regulatory limits.
Neither is inherently better; they serve different needs. PAMM favours simplicity and scale, while MAM favours per-investor flexibility. Many brokers run both from the same money-management layer. You can see how these models are delivered together on the FxTrusts PAMM, MAM and copy trading solution.
Pros and cons of PAMM accounts
Like any managed-investment model, PAMM has clear trade-offs for both sides.
| Advantages | Considerations |
|---|---|
| Passive access to an active strategy without trading yourself | Full market risk — capital can be lost, like any leveraged trading |
| Simple, automatic, proportional profit and loss allocation | No per-investor customisation; everyone shares the same outcome |
| Manager is incentivised by a performance fee tied to results | Fees reduce net returns and vary between managers |
| Manager can trade but generally cannot withdraw investor funds | Withdrawals are usually limited to set rollover points |
| Lets skilled traders scale a strategy across pooled capital | Outcome depends heavily on the manager's skill and honesty |
The single most important safeguard for an investor is due diligence: verify the broker's regulation, review the manager's transparent track record, and understand the fee terms and withdrawal schedule before allocating any capital.
Offering PAMM and MAM as a broker
For a brokerage, PAMM and MAM are attractive because they bring in two client types at once: money managers who want to run capital, and passive investors who want managed exposure. Delivering them requires a money-management module that connects to the trading platform and back office to handle investor allocation, proportional profit distribution, automated fee calculation, rollover processing, and clear reporting for both managers and investors.
That module does not stand alone — it sits alongside the client portal where investors browse managers, allocate capital, and track performance. In the FxTrusts stack, those investor-facing functions live in the traders room, while the pooled and mirrored account logic is provided by the PAMM, MAM and copy trading solution. Together they let a broker launch managed-account offerings without building the allocation and reporting engine from scratch.
Frequently Asked Questions
What is a PAMM account?
A PAMM (Percentage Allocation Management Module) account is a pooled money-management structure in forex and CFD trading. Multiple investors deposit funds into a single trading account operated by a money manager, and each investor owns a percentage share of that pool. Profits and losses are allocated back to investors in proportion to their share, and the manager typically earns a performance fee on the gains they generate.
What is a PAMM account in forex?
In forex, a PAMM account lets an experienced trader manage capital from many investors inside one master account. The manager places trades once, and the platform automatically divides the results across all participants by their percentage of the pool. Investors do not place trades themselves; they allocate capital, monitor performance, and can usually withdraw at set intervals.
What is the difference between PAMM and MAM?
PAMM allocates profits and losses by each investor’s percentage share of a single pooled account, so everyone gets the same proportional result. MAM (Multi-Account Manager) keeps each investor’s money in a separate sub-account and mirrors the manager’s trades into each one, which allows per-investor customisation such as different lot sizing, leverage, or risk limits. PAMM is simpler and fully pooled; MAM is more flexible and individually configurable.
Is a PAMM account the same as copy trading?
No. In copy trading, the investor keeps full control of their own account and chooses which signal providers to copy, adjusting or stopping at any time. In a PAMM account, capital is pooled and the money manager has discretionary control over the trading. Copy trading is investor-directed and self-service; PAMM is manager-directed and pooled.
Is a PAMM account safe?
A PAMM account carries the same market risk as any leveraged trading, so investors can lose part or all of their allocated capital. Structurally, PAMM systems are designed so the manager can trade but generally cannot withdraw investor funds to themselves. Safety depends on the broker’s regulation, the transparency of the manager’s track record, and the risk controls in place, so due diligence on both the broker and the manager matters.
How do PAMM account managers get paid?
Money managers are usually paid through a performance fee — an agreed percentage of the net profit they generate for the pool, applied at each rollover or settlement period. Some arrangements also include a management fee. The exact fee terms are set by the manager and disclosed to investors before they allocate capital.
Can a broker offer PAMM and MAM accounts?
Yes. Brokers offer PAMM and MAM through a money-management module connected to their trading platform and back office. It handles investor allocation, proportional profit distribution, fee calculation, and reporting. Offering PAMM, MAM, and copy trading lets a broker attract both money managers and passive investors on the same platform.
