MAM Trading

A Multi-Account Manager (MAM) trading system enables experienced investors to manage several individually-owned trading accounts. The trades placed by the manager are replicated across the pool of accounts, with characteristics like trade size altered depending on the preferences and risk level set by each investor. This page will detail how MAM trading works, outlining the pros and cons as well as listing the best MAM trading brokers in 2023.

How MAM Trading Works

MAM trading, sometimes shortened to multi-account trading (MAT), entails a master trader or fund manager to carry out trades for multiple users through a single terminal. The managed trading accounts of each investor and individual trader are combined into a large pool that is managed by the master trader. Any orders executed by the MAM trading manager are split amongst the associated accounts as per the risk appetite and available capital of each user.

Master traders utilise software from a MAM trading group or corporation that allows them to execute trades on behalf of their clients and investors. Some of the best MAM software and tools are compatible with industry-recognised platforms, such as MetaTrader 4 (MT4).

MAM Trading Software

Deposits & Withdrawals

Deposits and withdrawals for the individual sub-accounts within a MAM trading pool are handled by the investors and traders themselves; the fund manager cannot request deposits or withdrawals from their clients, they solely manage the trades.


MAM trading often has associated fees and stipulations, such as minimum deposits.

Minimum deposits can vary from low and accessible to up to tens of thousands for premium packages and more experienced master traders.

MAM trading users pay a fee to the master trader based on their performance, often by way of a percentage of returns. This incentivises the fund manager to be careful with your money and make the best trades. Some master traders also charge management fees to the brokers themselves in the form of an ongoing fixed percentage fee, though this is uncommon.

MAM Trading Example

The best way to conceptualise and understand MAM trading is to run through an example.

Suppose you invest $20,000 into a MAM forex trading account and you are allocated or have selected an experienced trader with a swing trading strategy.

If the first week’s investments earn you 30% gains, by the end of that week your balance will sit at $26,000 ($20,000 x 30% = $6,000).

However, the MAM trading manager will take a commission from these profits, for example, 20%. As a result, the fund manager would take $1,200 ($6,000 x 20% = $1,200) from your profits, leaving you with a final balance of $24,800 after the week’s trading, giving you a net profit of $4,800.

MAM Trading Strategies

Master traders execute trades either by equity size or lot allocation.

Equity Size

An example of equity size MAM trading management is as follows. Consider a multi-account manager that has five investors with a range of investment sizes totalling $50,000.

The MAM trading manager could execute a 10-lot position on EUR/USD in the master terminal.

The respective trades of each investor would then be:

  • Investor 1: $12,000/$50,000 * 10 = 2.4 lots
  • Investor 2: $15,000/$50,000 * 10 = 3 lots
  • Investor 3: $5,000/$50,000 * 10 = 1 lot
  • Investor 4: $10,000/$50,000 * 10 = 2 lots
  • Investor 5: $8,000/$50,000 * 10 = 1.6 lots
  • Total number of lots: 10

What is MAM trading

Lot Allocation

For lot allocation, the trades are split by the proportion of lots each trader makes available. For example, consider two active sub-accounts within a MAM trading pool that have lot allocations of 2 and 3 lots, respectively.

If the master trader again makes a 10-lot trade, the trading volume for each sub-account would be:

  • Investor 1: 2/5 * 10 = 4 lots
  • Investor 2: 3/5 * 10 = 6 lots

As you can see, it is a very similar approach to equity size MAM trading, only the investors put forward relative trade sizes rather than specific equity amounts.


There are some key differences between Multi-Account Manager (MAM) trading, Percentage Allocation Management (PAM) and Lot Allocation Management (LAM) solutions.

PAM terminals enable investors to allocate a portion (as a percentage) of their total trading capital to copy trades from a master.

also allow you to follow multiple traders and diversify your portfolio by allocating different percentages to different investors.

On the other hand, gives the power to the investor to choose the number of lots that can be traded by various master investors. is essentially a more basic version of that aim to lower the risk of trading losses.
