Think of PAMM and MAM as two different ways a professional forex trader (a money manager) can trade on behalf of multiple clients at once without having to log into a dozen different accounts every morning. 1. PAMM (Percent Allocation Management Module) ​The "Group Soup" Approach ​How it works: Everyone dumps their money into one big central pot. The manager trades that entire pot as a single block. ​The Math: Everything is strictly percentage-based. If you put in 10% of the money in the pot, you get 10% of the profits (or losses) from every trade made. ​The Vibe: Completely hands-off. The broker’s system handles the math automatically in the background. You just watch your equity percentage move up or down. ​2. MAM (Multi-Account Manager) ​The "Custom Order" Approach ​How it works: Your money stays in your own individual account, but it's linked to the manager’s main trading desk. ​The Control: The manager can customize how trades are placed for each person. They can send 1 lot to a client with a big account, 0.1 lots to a client with a small account, or apply different risk rules depending on what each client asked for. ​The Vibe: Flexible and tailored. It’s built for bigger accounts or clients who want specific risk management.
