PAMM/MAM Plugin for Forex Brokers: What to Buy, What to Ask and What to Avoid
PAMM and MAM plugins appear similar in feature tables, and they differ in the details that decide whether investors trust you. This guide helps buyers choose a plugin and avoid the usual traps.
Decide the model first
Pooled funds (PAMM) and separate accounts with allocated orders (MAM) need different features. Decide which you want, then shortlist plugins that support it. Compare with copy trading in our comparison.
Features to require
- Clear allocation methods and rounding rules.
- A configurable fee engine with high-water mark and payout timing.
- Investor portal with live positions, fees and statements.
- Investor-side limits and exit controls.
- Audit logs and reconciliation with your CRM.
Questions for the vendor
Ask for worked examples of allocation and fees, a list of supported platform versions, an upgrade policy and a reference customer. Ask what happens to investor records if you leave.
Pricing models
Plugins may be priced per manager, per investor account, as a percentage of fees or as a flat licence. Model your expected growth under each to see which is cheapest at scale.
Warning signs
Beware vague fee calculations, no investor reporting, no test environment and promises about investor returns. Check regulation before launch with our jurisdiction overview.
Reference calls are worth the time
Ask the vendor for a customer you can call, ideally a broker of similar size. Ask about reliability, support response, fee accuracy and how upgrades were handled.
Five minutes with a customer will tell you more than a day of documentation. If no reference is available, treat that as information.
A vendor question table
Send the same questions to every vendor.
| Question | Vendor A | Vendor B |
|---|---|---|
| Is it PAMM, MAM or both? | ||
| How are fees calculated? | ||
| How are deposits and withdrawals handled mid-period? | ||
| What reports do investors see? | ||
| How are partial fills allocated? | ||
| What is the pricing model? | ||
| What references can you provide? |
Put the answers side by side. Differences usually reveal scope gaps.
A worked example of a reference call
A buyer calls a vendor’s reference, a broker of similar size. The reference says implementation took longer than promised because of a missing integration, but support was responsive and the system has been stable. The buyer asks about fees and finds that one report required a custom change.
The call gives the buyer two items to negotiate: a fixed date for the integration and a price for the custom report. A reference call costs thirty minutes and produces real leverage.
Pricing models
Plugins may be priced per manager, per investor account, as a percentage of fees or as a flat licence. Calculate each model for your expected number of managers and investors. Ask whether prices change with volume and whether there are minimums.
Warning signs
- No clear description of fee calculation.
- No ability to test partial fills.
- Vague answers about regulation.
- No references.
- Pressure to sign quickly.

Investor-facing features to insist on
Investors will judge your service by what they see. Make sure the plugin provides clear statements, accessible performance data, transparent fee information and a way to ask questions. Ask to see the investor view during the demo and test it as an investor would.
A plugin that is excellent for managers but confusing for investors will cost you in support requests and lost trust.
Operational costs
Besides the licence, count the staff time for reconciliation, investor support and manager onboarding. Ask the vendor how much time similar brokers spend. Add a margin for your first months.
Regulatory review
Take advice on whether your use of the plugin triggers licensing or conduct requirements. Ask the vendor whether it provides compliance features such as disclosures and audit trails. Add legal costs to your budget.
Testing fee calculation before you buy
Fee calculation is where trust is won or lost. Prepare three test cases: a simple profitable period, a period with a loss followed by a gain that tests the high-water mark and a period with a mid-period deposit and withdrawal. Work out the expected fees by hand and ask the vendor to run the same cases in a test environment.
Compare the results line by line. Any difference must be explained before you buy. Keep the test cases and results with your records, because they will be useful when an investor questions a statement.
Understanding the vendor’s roadmap
Ask what the vendor plans to add over the next year and how customers influence the roadmap. Ask how often updates are released and how they are tested. A plugin that is actively developed is more likely to keep pace with platform changes and regulatory expectations.
Also ask what happens if the vendor ceases to support the plugin. A clear answer, perhaps involving source access or data export, is a sign of a mature vendor.
