MAM Partnership

A MAM (Multi-Account Manager) Partnership is an arrangement in which an experienced trader — the money manager — trades many individual client accounts at once from a single master interface, while the broker supplies the allocation technology and the Introducing Broker who sourced the clients earns volume rebates and often a share of fees.

The defining feature of a MAM is that client funds stay in each client's own segregated account, in their own name. The manager places one block trade from the master, and a MAM plugin allocates it across every connected client account by a chosen method — by equity, by balance, or by a fixed lot multiplier — so each account takes a slice proportional to its size or setting.

This structure lets a manager run, say, a $500,000 aggregate pool spread across 25 clients as if it were one book, while each client keeps visibility, segregation, and the ability to adjust their own risk or withdraw. The manager charges performance and/or management fees; the referring IB is paid a per-lot rebate on the volume and, by agreement, a cut of the manager's fees.

For a partner, the MAM is the vehicle for onboarding investors who want professional management without surrendering ownership of their capital. Unlike a PAMM — where funds are pooled into one account — a MAM keeps accounts individual and supports more complex allocation, which appeals to higher-net-worth clients who value transparency and control.

The broker installs a MAM plugin (a master-terminal add-on for MT4 or MT5) and links each participating client's live account to the manager's master account. The clients sign a limited power of attorney authorizing trading — but not withdrawal — so the manager can trade on their behalf while ownership stays with the client.

When the manager executes a trade from the master, the plugin fans it out to every connected account using the configured allocation method. Equity allocation gives each account a share proportional to its equity; balance allocation uses balance; a lot-multiplier method lets specific accounts take larger or smaller size than a strict proportional split — useful for tailoring risk per client.

Fees flow from the manager's terms: a management fee on assets under management and/or a performance fee on profits above a high-water mark, typically settled monthly. The IB earns a rebate on every allocated lot and, where the agreement allows, a negotiated percentage of the manager's fees — blending volume income with fee income.
