PAMM vs copy trading: allocation, control and fees

PAMM and copy trading both let an investor follow trading decisions made by someone else. The difference is how those decisions reach the investor’s account. A PAMM arrangement allocates results from a managed trading account according to each investor’s share. Copy trading reproduces a provider’s trades in another account, with position sizes determined by the copying rules.

Neither label tells you how much control you retain, what the service costs or how quickly you can leave. Both can expose your money to trading losses. A useful comparison starts with the allocation method, then checks the account controls, fee calculation and exit terms.

What is being allocated?

In Brokeree’s documented PAMM model, a manager trades a shared account and the system allocates trading results among participants at a rollover. A rollover is an accounting process that updates the allocation; it is not a promise of a positive return. The broker configures the service and its operating conditions.

With cTrader Copy, allocated funds go into a dedicated copy-trading account under the investor’s cTrader ID. The provider’s trading activity is copied into that account using equity-based sizing. These are two documented implementations, not definitions that establish the terms of every product sold under either name.

The distinction is not “percentages versus copying”. Copying can use percentages too. Nor does a trading-account diagram establish who legally holds client money. Custody, client-money treatment and the parties to the agreement must be checked separately.

The same investment, two different calculations

Consider a hypothetical USD 2,500 investment. The examples below explain the mechanics; they are not forecasts, recommended trade sizes or Vertex account terms. Assume one currency, no deposits or withdrawals during the calculation, and ignore fees and execution differences initially.

In a simple PAMM example, total participating equity is USD 50,000. The investor’s share is 2,500 ÷ 50,000, or 5%. A USD 1,000 trading gain would allocate USD 50 to that investor before applicable fees. A USD 1,500 trading loss would allocate a USD 75 loss. The same percentage applies to either outcome under these assumptions.

For the copy-trading example, suppose the provider has USD 20,000 of equity and opens a position of 0.8 lots. Applying cTrader Copy’s documented ratio gives 2,500 ÷ 20,000 × 0.8 = 0.1 lots in the investor’s account. Equity here includes unrealised gains and losses, so it can differ from the cash balance.

The first calculation divides a trading result. The second sizes a trade. It does not establish that the investor will receive the provider’s exact percentage return: cTrader identifies execution prices, margin, available instruments and trade-size limits as reasons copying may differ.

Question	PAMM example	Copy-trading example
What does the calculation determine?	The investor’s share of the managed account’s result.	The position size copied into the investor’s account.
What does USD 2,500 represent here?	A 5% share of USD 50,000 participating equity.	12.5% of the example provider’s USD 20,000 equity.
What still needs checking?	Allocation timing, fee treatment and what happens when participation changes.	Execution, instrument availability, position-size limits and account controls.

These figures describe different hypothetical accounts. They cannot be used to compare investment performance. For a fuller explanation of the first calculation, see our guide to PAMM allocation, fees and investor risk.

Control depends on the account rules

“My own account” does not necessarily mean “I can edit every trade”. The cTrader Copy investor FAQ says investors cannot trade manually in the dedicated copy-trading account or close individual copied positions there. Stopping the strategy closes its copied positions together. Other systems may work differently.

cTrader Copy also documents an equity stop loss. When triggered, it stops copying and initiates closure of copied positions, but the final equity is not guaranteed to match the chosen threshold. Gaps, liquidity and execution conditions can affect the outcome. It is therefore misleading to describe a loss threshold as guaranteed capital protection.

For either arrangement, distinguish the decisions you make from those delegated to the trader. Selecting a strategy, choosing an allocation, setting an available account-level limit and closing an individual position are separate permissions. An offer should make clear which of them you have.

Compare the fee base, not just the percentage

A headline “20% fee” is incomplete. It might refer to eligible profits, while another charge applies to account equity or trading volume. Brokeree’s PAMM documentation describes configurable performance, management, entry, deposit and withdrawal fees. That is a list of capabilities, not a statement that every PAMM offer charges all of them.

cTrader Copy’s fee documentation distinguishes performance, management and volume charges. Its management fee is expressed annually and accrued daily; its volume fee is calculated per side of a trade. A comparison that looks only at the performance-fee percentage can miss those other costs.

Here is a separate hypothetical fee calculation. An account starts with USD 2,500 and makes USD 125 after trading costs but before strategy fees. Assume all USD 125 is eligible for a 20% performance fee and there are no other charges or cash movements. The fee is USD 25, leaving USD 100 and closing equity of USD 2,600. The investor’s gain is 4%, although the gain before that strategy fee was 5%.

If the same account instead loses USD 125, that assumed profit-only fee would be zero and equity would be USD 2,375. It does not follow that all charges disappear in a losing period: an applicable management or volume fee may still be payable. Actual agreements define the order of deductions and the profit eligible for charging.

A high-water mark can prevent a performance fee being charged twice on the same gains. Check its calculation and reset rules. It is a fee mechanism, not protection against trading losses.

Stopping a strategy and receiving a withdrawal are different steps

An exit can involve stopping participation, closing or reallocating exposure, calculating fees, releasing money to a withdrawable balance and processing the withdrawal itself. A button labelled “stop” does not establish when money reaches a bank account.

For cTrader Copy, the investor guide distinguishes removing some funds while copying from stopping entirely. Stopping closes copied positions and transfers the remaining funds to the main account. If a relevant market is closed, the account can remain in a stopping state until positions can close. Removing funds while continuing to copy also has conditions.

For a PAMM offer, read the actual rollover and withdrawal provisions rather than assuming an immediate exit from the software’s marketing description. Ask how an open position, insufficient free margin, a pending fee or a lock-in provision affects the request. The answer should identify the contractual rule and the person responsible for processing it.

The documents should answer the comparison

A useful offer lets you reconcile four things: how exposure or results are allocated, which actions you can take, every applicable charge, and the exit process. Ask for an example statement that joins the opening equity, trading result, cash movements, fees and closing equity. If those numbers cannot be reconciled, a performance chart will not fill the gap.

Platform documentation explains software behaviour. It does not establish that a particular broker or manager may offer the service to you. Availability and permissions need checking for the legal entity, product and country involved; a regional label such as “Africa” is not a single set of account terms.

For information about Vertex’s published offering, read the Vertex PAMM overview alongside the applicable strategy terms and risk disclosure. This comparison does not confirm that Vertex offers cTrader Copy or every Brokeree configuration described above.
