What Is MAM and How Does It Work?

A MAM account allows a money manager to trade across several clients’ accounts from one master account. MAM stands for Multi-Account Manager. The software allocates trading activity to the linked accounts according to their settings, while each client has their own balance, positions and trading results.

Imagine a manager applying the same strategy to clients with different amounts of capital. One has $12,000 available; another has $36,000. Entering the same lot size for both would give them very different exposure relative to their funds. Entering and adjusting every trade separately would also become difficult as the client list grows.

MAM brings those accounts into one trading workflow. To understand it properly, it helps to follow what happens from the client’s first deposit through to trade allocation and the manager’s payment.

How a MAM Account Works Step by Step

1. The client opens and funds an account

The client opens an eligible trading account with the broker and completes the required verification. Funds are deposited into the client’s account under the broker’s funding process. In a typical MAM arrangement, the client does not send their trading capital to the manager’s personal bank account.

2. The client agrees to the manager’s terms

Before trading begins, the client reviews the strategy, fees, allocation method and withdrawal conditions. They also give the manager trading authority through the broker’s required agreement or authorisation process.

The money manager may also be called the master trader. The master account is the account they use to send trading instructions. Giving someone authority to trade does not normally give them authority to withdraw your funds for their own use.

3. The account is linked and allocation settings are applied

The client’s account is connected to the manager’s setup. The allocation settings determine how much trading exposure it receives. Depending on the system, this may be based on equity, balance, fixed lots or a multiplier.

These settings should be understood before the account starts participating. A small lot size does not automatically mean low risk: the account size, stop distance and total open exposure matter too.

4. The manager trades through the master account

When the manager opens a position, the MAM system allocates the trading activity across participating accounts. Changes and closures can also be handled centrally, subject to the platform’s functionality.

Each client’s positions use margin in their own account. Open profits and losses affect equity; realised results affect the account balance when positions close. The client can monitor their account without entering every trade themselves.

5. Fees are calculated under the agreed schedule

The manager receives the fees agreed with the client. Where automated collection is supported, the broker’s system calculates and deducts the amount from the client’s account and credits the manager’s designated account or wallet.

The payment date and calculation rules depend on the service. A fee may become payable at a scheduled interval or when participation ends, rather than only when the client withdraws a profit.

How Trades Are Allocated Across Client Accounts

Think of the master account as a control room. The manager decides what to trade, while the allocation settings determine the position size for each connected account.

Here is a hypothetical example using allocation proportional to equity, with an optional multiplier. Assume the master has equity of $60,000 and opens a 1.50-lot EUR/USD position.

Under this particular method, the client’s position equals the master’s lot size multiplied by the client-to-master equity ratio and the agreed multiplier.

Clients B and C have the same equity, but Client C receives half the exposure because of the lower multiplier. These are calculated position sizes, assuming sufficient margin and that the instrument’s volume rules allow them. Other MAM systems may allocate an aggregate order among clients using a different formula.

To see what the positions mean in money terms, suppose EUR/USD moves 40 pips in the clients’ favour and all three positions close at the same price. With a standard 100,000-unit contract and USD accounts, the approximate profit before costs would be $120 for A, $360 for B and $180 for C. An equal move against the positions would produce corresponding losses before costs.

The trading idea is shared, but the dollar result depends on each account’s position size.

Common Allocation Methods

Fixed lots: Each account receives a specified trade size. If a client withdraws capital, that setting may need adjusting because the same number of lots would represent more exposure relative to the remaining funds.

Balance or equity based allocation: Position sizes are calculated using account values. Equity includes floating profits and losses; balance generally reflects booked transactions and realised results. This distinction can affect allocations while positions remain open.

Multipliers: A factor increases or reduces the position size calculated under the selected method. A lower multiplier reduces exposure to that trade, but does not guarantee a maximum loss or a particular account return.

Available methods and who can change them depend on the broker and software. Changes to a setting may affect future trades without resizing positions that are already open.

How MAM Managers Earn and What Investors Pay

Money managers earn through the fees agreed with their clients. There is no single fee structure or universal percentage for all MAM accounts. Two managers using the same broker may have different terms.

Performance Fees

A performance fee is a share of the profit eligible for charging under the agreement. The definition of eligible profit matters: the calculation may consider closed trades only, or also take open profits and losses into account.

Consider a hypothetical client with a $12,000 starting balance and an agreed performance fee of 18%. At the fee date, the account has earned $1,500 after normal trading costs but before the manager’s fee.

Assume all positions are closed, the full profit is eligible for charging, there are no earlier losses to recover, and there are no other fees, deposits or withdrawals.

The manager earns $270 and the client retains $1,230 of the profit. The 18% applies to eligible profit, not to the client’s original $12,000 deposit. These figures illustrate the calculation; they are not a quoted zForex manager rate.

How a High Water Mark Affects the Fee

A high-water mark is a reference used by some performance-fee arrangements to avoid charging again on profits already subject to a fee. After a loss, the account must recover to the relevant reference level before further eligible gains attract a new performance fee.

For consistency, continue the example using cumulative trading profit after trading costs but before performance fees. Assume the agreement measures its high-water mark on that same basis, with no deposits or withdrawals.

• The first charge applies to $1,500 of cumulative profit, establishing a $1,500 profit reference.
• Trading losses reduce cumulative profit to $900. No new performance fee is due under this model.
• Cumulative profit later reaches $1,800. Only the $300 above the previous reference is newly chargeable, producing a $54 fee at 18%.

This example tracks cumulative trading profit, not the cash balance after fees. Actual agreements can use different reference conventions. Check how the high-water mark is defined, whether it resets, and how deposits and withdrawals are treated. Do not assume every manager offers this protection.

Management Fees and Other Possible Charges

A management fee may be calculated as a percentage of the balance or equity under management. It can apply even when the account loses money.

For example, a hypothetical annual management fee of 1.2% on an unchanged $24,000 fee base would equal $288 per year, or $24 per month if divided into twelve equal charges. Actual billing can depend on daily account values and the time under management.

Some arrangements also include a fixed subscription, a joining fee or a volume-based fee. A volume fee is linked to trading activity rather than profitability, so the manager may earn it during a losing period. Not every service offers or applies these charges.

Before joining, establish the percentage or amount, the calculation base, the payment frequency and which charges can apply when performance is negative.

How Fees Work at zForex

zForex does not add a separate fee for copying through its PAMM and MAM services. The master trader sets the applicable service fees, and the investors who follow that trader pay them under the agreed terms.

Manager fees should be considered separately from normal trading costs, such as spreads, trading commissions and any applicable overnight charges. Review both the manager’s offer and the underlying trading account conditions to understand the total cost of participation.

What the Client Controls and What the Manager Controls

In a typical MAM arrangement, the client owns the trading account and authorises the manager to trade it. The manager can make trading decisions within that authority, while deposits and withdrawals generally remain under the client’s control.

However, access to funds is still subject to account conditions. Open positions use margin, accrued fees may need settling, and withdrawing funds can leave less capital supporting existing trades.

Before leaving a manager, clarify three separate actions: stopping new allocations, dealing with existing positions and withdrawing available funds. Disconnecting an account should not be assumed to close every open trade automatically.

MAM Compared With Copy Trading and PAMM

MAM, copy trading and PAMM all allow clients to participate in another trader’s strategy. The differences concern how that participation is organised and which controls each service provides.

These are general distinctions. Copy-trading platforms can also offer equity-based sizing and multipliers, while PAMM implementations differ in account structure and accounting. Compare the features of the actual service, including its allocation options and client controls.

For a client, the practical questions are who can trade, how exposure is calculated, what fees apply and how participation can be stopped.

Benefits and Risks of a MAM Account

For a money manager, MAM reduces repetitive order entry and makes it easier to handle trading activity across multiple accounts. Where supported, it also allows different allocations for clients following the same strategy.

For an investor, the benefit is delegated trade execution with visibility into an individual account. The investor still needs to assess the manager, understand the terms and monitor results.

The main risks include:

• Strategy and leverage risk: Poor decisions, concentrated positions or excessive leverage can cause substantial losses across the linked accounts.
• Allocation risk: A fixed lot setting or multiplier may become unsuitable after a withdrawal or a change in account equity.
• Execution differences: Slippage, minimum trade sizes and insufficient margin can cause accounts to receive different results or miss an allocation.
• Misleading performance comparisons: A master’s return may reflect different exposure, costs or participation dates from those of a particular client.

MAM handles the distribution of trading activity. It does not assess whether a trade is sensible or make the strategy profitable.

What to Check Before Choosing a MAM Manager

A headline return gives only part of the picture. Look at how the manager produced it and how much account value was at risk along the way.

• Track record: Check its length and whether it reflects live trading rather than only a backtest.
• Drawdown: Examine peak-to-trough losses and whether the figures include open positions.
• Trading approach: Understand the markets traded, typical holding periods and how losing trades are handled.
• Exposure: Review position sizing, leverage and whether your allocation differs from the advertised account.
• Fees: Check every charge, its calculation basis and whether reported returns are before or after manager fees.
• Exit conditions: Understand the treatment of withdrawals, disconnection, outstanding positions and unpaid fees.

A manager does not need to reveal every entry rule, but should be able to explain the broad strategy and its risks. An account that holds EUR/USD, gold and indices simultaneously may have several instruments yet still carry concentrated exposure to the same market event.

Frequently Asked Questions

Does a MAM manager have to trade manually?

No. Depending on the platform and broker’s permissions, the manager may trade manually or use an automated strategy. MAM describes how trading activity is allocated across accounts, rather than how the trading decisions are generated.

What happens if my account has insufficient free margin?

An allocation may fail or be handled differently under the system’s rules. Your account can then diverge from the manager’s results. Check how rejected orders are reported and whether any retry or adjustment process applies.

Will I inherit positions that were opened before I joined?

That depends on the service. Some setups can synchronise existing positions, while others begin with new trades only. If existing positions are opened in your account, your entry price may differ from the manager’s original price.

Does depositing more money count as profit for a performance fee?

A deposit is additional capital, not a trading gain. A performance-fee calculation should distinguish cash movements from trading results. Ask how deposits and withdrawals affect the fee base and high-water mark, where one applies.

Can I trade manually while my account is linked to a manager?

Permissions vary. If manual trading is allowed, those positions can use margin needed for the manager’s allocations and change the account’s overall exposure. Confirm how personal trades are treated in performance reporting and fee calculations.

Are MAM accounts limited to forex?

No. Depending on the broker’s instruments and MAM configuration, managers may also trade gold, indices, energy products or stock CFDs. Check which markets are available for the particular service and account.
