What is MQL5 Signals?

What it means

Because it mirrors an account rather than distributing a file, the strategy behind the trades is invisible and irrelevant to the service. A provider can be trading manually, running an Expert Advisor, or driving the account from an external program in any language — MQL5 only ever sees the executed positions.

Why it matters

The public statistics page is the useful part. Growth, maximum drawdown, trade count, account age and the equity chart are computed by the platform from the broker feed rather than supplied by the provider, which makes them considerably harder to dress up than a self-published screenshot. Subscription revenue is split with the platform.

What this changes in practice

Registration requires seller status with identity verification, a real account rather than a demo, and leverage at or below 1:500. One trading account maps to exactly one signal, so a provider cannot quietly run several attempts and publish whichever survived — a constraint that does more for subscriber protection than most disclosure rules.
