MAM accounts and lot allocation: control in the details

In MAM each investor keeps their own sub-account while one manager order is distributed across them. How lot allocation works.

MAM is the only structure that hands the investor a visible sub-account; that single feature answers many transparency questions and creates new ones about lot allocation. Understanding the allocation logic is the precondition for reading your own sub-account report correctly.

Multi-Account Management is designed for investors who want their own separate account and professional management at the same time. The manager issues one order and the broker’s system distributes it across the sub-accounts.

How allocation works

Each sub-account’s volume can be set pro-rata to capital, by a fixed multiplier, or a mix. Two investors in the same MAM can therefore experience one identical trade very differently.

Benefits and cautions

  • You see your own sub-account: balance, trades and separate reporting.
  • Fee and exit terms are set by that manager’s account; read them fully.
  • Lot allocation does not remove your risk — losses are distributed by the same ratio.

See the MAM account list and the MAM guide.

Frequently asked questions

Do I hand over my password in MAM? No. The manager gets trading access to your sub-account through the broker’s infrastructure; your master password stays with you. Use the investor password for viewing reports.

Pro-rata or multiplier — what is the difference? “Pro-rata to capital” allocates automatically by each sub-account’s money; a “multiplier” manually scales the manager’s trades onto you.

How do exits work? MAM exits follow that account’s own terms; usually faster than PAMM since the sub-account is separate.

How does MAM lot allocation differ from a PAMM percentage share? In PAMM your share is a stated ratio of the whole account and everything follows that ratio. In MAM, allocation is computed per order; your outcome may not exactly equal your capital ratio, depending on that account’s allocation rules. Read the allocation rules in the account’s text.

A closing note

Set your allocation so the manager’s trade effect matches your risk tolerance; use the position-size calculator for the math and see the account manager guide too.

Checklist before entering a MAM

  • Specify the allocation type (pro-rata or multiplier)
  • Compute the manager trade effect on your own capital
  • Keep your master password; reports via the investor password
  • Read that account’s fee and exit terms fully
  • Review your sub-account report regularly
