MAM, MAM Plus and PAMM fund management

Designed for fund managers, professional traders and investors, our fund management technology simplifies trade allocation, account administration and performance reporting. Choose the solution that best matches your preferred level of flexibility, control and account structure.

Fund manager allocating trades across multiple client accounts
Multi-Account Manager — the industry standard. Trade-by-trade allocation in lots.

What is MAM?

When the manager opens a position, MAM divides that position into lots and assigns a slice to each investor account. If an investor holds 20% of the total capital in the pool, they receive 20% of the lots.

Every allocated position appears in the investor's own account. They can see the symbol, the entry price, the volume and the running P&L on their own terminal — full transparency, trade by trade.

Allocation methods
  • Proportional to Balance
  • Proportional to Equity
Minimum allocation unit
0.01 lot
Account type
Standard USD trading account, auto-created on subscription
Risk
Each investor account carries the risk of the lots distributed to it

Best for: Managers running lower trade frequency with well-capitalised investors, where a 0.01 lot rounding step is immaterial.

  • Professional traders managing multiple client accounts
  • Fund managers requiring flexible trade allocation
  • Clients who prefer to maintain separate trading accounts
  • Strategies that require customised account or risk settings
Everything MAM does — at 100× the precision.

What is MAM Plus?

MAM Plus uses the same allocation engine as MAM, with one structural difference: investor accounts are opened as cent accounts rather than standard USD accounts.

On a cent account, the smallest tradable unit is one cent lot — the equivalent of 0.0001 of a standard lot. Because allocation is calculated in that unit, MAM Plus can express an investor's share far more accurately than a system limited to 0.01 lot steps.

The result: no investor is rounded down to zero, no investor is silently over-weighted, and the pool's actual exposure tracks the manager's intended exposure almost perfectly.

Allocation methods
  • Proportional to Balance
  • Proportional to Equity
Minimum allocation unit
0.0001 lot (one cent lot)
Account type
Cent trading account, auto-created on subscription
Risk
Each investor account carries the risk of the lots distributed to it

Best for: Managers with a wide range of investor sizes, high trade frequency, scalping or intraday strategies, or anyone building a book that includes smaller retail investors.

A Master allocating in cent lots across subscribed investors

How MAM Plus Works

Investors subscribe

Investors subscribe to a selected Master and their capital is added to the managed pool.

The Master trades

The Master places trades through one central account, without adjusting the lot size for each investor.

Results are allocated

Each trade, profit and loss is allocated according to the investor's share of the total capital and assigned trading volume.

New trades only

New investors are only included in trades opened after their subscription becomes active.

  • Centralised Fund Management The Master manages the total subscribed capital through one central account, making multiple investor funds easier to oversee.
  • Consistent Trade Execution All trades are executed through the Master account, helping reduce price and execution differences between investors.
  • Cent-Lot Accuracy Allocation is calculated in cent lots — 0.0001 of a standard lot — so small investors are never rounded down to zero and no one is silently over-weighted.
  • Flexible Trading for Masters The Master can focus on the overall trading strategy without manually adjusting the lot size for each individual investor.
  • New-Trade Allocation New investors are only included in positions opened after their subscription becomes active. Existing trades remain unaffected.
  • Efficient Unsubscription When an investor unsubscribes, only the portion of the position allocated to that investor is closed, without affecting the remaining investors.
Investors allocating capital to a PAMM strategy
Percentage Allocation Management Module — no lots, pure profit-and-loss distribution.

What is PAMM?

PAMM works at the account level rather than the trade level. Investor capital is treated as a single managed pool, the manager trades that pool, and at settlement the resulting profit or loss is distributed to each investor according to their percentage share.

Because nothing is allocated in lots, there is no minimum lot size and no rounding problem at all — a share is a share, expressed as a percentage.

The trade-off is granularity of view: investors see their P&L and their share, not an individual line for every position mirrored into their account.

Allocation methods
  • PnL distribution
Minimum allocation unit
Not applicable — no lot allocation
Account type
Trading account, auto-created on subscription
Risk
Each investor account carries the risk of its distributed P&L

Best for: Managers running strategies where per-trade visibility matters less than portfolio-level results, and investors who want a simple percentage-of-the-fund structure.

  • Investors seeking access to a managed trading strategy
  • Fund managers looking to manage capital under one central structure
  • Strategies that require proportional trade and performance allocation
  • Investors who prefer a simplified and automated management process
