PAMM vs. MAM: What Brokers Need to Know Before Choosing a System

Technology might have changed the pace and expectations in the forex market, but clients still care about results. Studies suggest that between 74% and 89% of retail traders lose money when trading CFDs and forex. 

And that’s not good news for brokers. It can potentially reduce trading volume and have an impact on their bottom line. 

One way to avoid such catastrophic outcomes for clients is by launching shared investment accounts.

Professional money managers, high-volume traders, and passive investors all need flexible systems that can handle scale, risk, and transparency. Solutions like PAMM (Percentage Allocation Management Module) and MAM (Multi-Account Manager) prove their value in this area. They make it possible to manage multiple accounts without compromising execution quality or investor control.

If you’re a broker working with asset managers—or planning to—you’ll need to understand how these systems work, how they differ, and which one aligns best with your business model and your clients’ expectations.

What Is PAMM?

PAMM stands for Percentage Allocation Management Module. It’s a system that allows investors to allocate funds to a professional trader, who then manages a pooled account on their behalf. The trader uses a single master account to execute trades, and the system automatically distributes profits and losses among investors depending on how much each one contributed.

It’s a hands-off model for the investor. They don’t place trades themselves. Instead, they choose a manager, allocate funds, and let the system handle the rest. Investors can often spread their funds across multiple managers to diversify their exposure.

From the broker’s perspective, PAMM keeps things centralized. Trades are executed once from a single account, which reduces server load and minimizes slippage. It’s also more efficient than trying to copy trades across dozens or hundreds of accounts individually.

For brokers serving passive investors or those working with portfolio managers, PAMM’s clean, automated way is the best way to scale that service without overcomplicating the infrastructure.

What Is MAM?

MAM stands for Multi-Account Manager. Like PAMM, it helps professional traders manage multiple investor accounts at once, but it works a bit differently at the backend.

In a MAM setup, the trader executes orders from a master account, but instead of pooling funds, the trades are mirrored across individual client accounts. Each investor has their sub-account, and the system allocates trade sizes based on predefined ratios or lot sizes set by the investor or broker.

MAM gives brokers and traders more flexibility in how trades are distributed. For example, some investors might prefer fixed lot allocations rather than percentage-based ones. This makes MAM a popular choice for asset managers who want finer control over how strategies are applied across clients.

From a technical perspective, MAM systems require trade replication, which increases server load compared to PAMM. That can affect execution during high-volume periods, depending on how the system is built. But in return, investors get full visibility into their accounts, including every position and transaction, which some clients strongly prefer.

Key Differences Between PAMM and MAM

PAMM and MAM are both built to solve the same problem—how to manage multiple investor accounts—but they approach it in fundamentally different ways.

With PAMM, all investor funds are combined into a single pool. The money manager trades that one account, and the system automatically allocates profit and loss based on each investor’s share. This model works on the backend and tends to deliver cleaner execution since there’s only one trade being sent to the market.

MAM, on the other hand, keeps each investor’s funds in a separate sub-account. The system copies trades from the master account into these individual accounts. This gives investors full visibility into their positions and allows more granular control over trade allocation. But it also creates more strain on servers as each trade has to be replicated in real-time across multiple accounts.

In short, PAMM focuses on simplicity and performance, while MAM gives more flexibility and transparency. Which one makes more sense depends on the type of clients you’re serving and the kind of experience you want to deliver.

How to Choose PAMM?

Choosing the right technology partner is a serious decision for any brokerage. The tech you pick will shape how your business runs, how investors interact with their accounts, and how scalable your offering really is.

Brokeree has a PAMM platform with a focused set of features designed around the needs of both brokers and investors. A built-in risk management system lets investors set stop-loss levels per provider—so they can define how much risk they’re willing to take without needing to monitor trades constantly. The system also gives investors the freedom to withdraw funds at any time. Investors can withdraw anytime, which gives them flexibility without needing to go through account managers.

From an operations standpoint, the interface is structured. Each user—admin, manager, or investor—has a portal with tools built for their role. That separation keeps things streamlined while still allowing each group to access the tools and information they need.

Brokeree’s Ratings Module is another standout feature. It gives brokers the option to display interactive graphs and live performance data on their websites based on real trading activity. It’s a transparent way for investors to evaluate strategies and track records before allocating funds.

The system also supports investment across different trading servers, allowing for broader diversification options. For brokers, that flexibility opens up more use cases without complicating setup.

And when it comes to implementation, Brokeree offers a turnkey launch process and full-day technical support. Brokeree handles setup and support so your team doesn’t waste time on configuration.

Conclusion

PAMM and MAM systems have become important for brokers offering managed accounts. If you’re planning to scale that side of your business, choosing the right model—and a reliable tech partner—is key. Brokeree’s PAMM solution is built for that: scale, control, and day-to-day reliability.

FAQs

Which system gives investors more control?

MAM generally gives more flexibility. Investors can set specific trade allocation rules and often have full visibility into positions within their accounts. PAMM focuses more on simplified management and automated distribution of results.

Are PAMM systems suitable for all types of brokers?

Not necessarily. PAMM works best for brokers serving passive investors or offering strategy-following features. MAM is often used by asset managers or traders who need more complex allocation methods and transparency.

Can both PAMM and MAM run on MT4 and MT5?

Yes. Most modern solutions, such as Brokeree, are compatible with both platforms. Some brokers use PAMM or MAM systems that support multi-server environments as well, which is useful if you’re running separate MT4/MT5 infrastructures. Brokeree’s PAMM is a cross-platform solution that works on cTrader and MT4 and 5. 

What are the technical considerations when choosing PAMM or MAM?

PAMM tends to be lighter on server resources since it processes fewer trades. MAM, by design, requires trade replication across accounts, which can increase load and latency. Consider how the system handles execution, failover, and reporting before committing.

How do investors track performance in PAMM and MAM systems?

Most platforms offer investor dashboards with live or delayed performance metrics. PAMM systems often provide aggregate performance views, while MAM systems allow account-level tracking. Some solutions include public ratings or performance rankings for managers.
