MQL5 Signals

MQL5 Signals (mql5.com/en/signals) is MetaQuotes' first-party signal-following marketplace built directly into MetaTrader 4 and 5. Signal providers connect a live trading account; subscribers pay a monthly subscription to receive automatic trade copying onto their own MetaTrader installation via MetaQuotes' relay infrastructure.

For EA buyers, the signal-following economics are usually irrelevant — what matters is the verification function. Every signal listed on MQL5 Signals exposes the underlying account's trade-by-trade history, equity curve, drawdown timeline, monthly returns, and execution statistics (average slippage, fill rate). The data is fetched directly from the broker server through MetaQuotes' infrastructure, providing cryptographic auditability equivalent to MyFXBook.

The MQL5 Signals ecosystem has structural advantages over MyFXBook for the specific use case of verifying EA marketing claims. First, signal providers must maintain the live account to keep collecting subscription revenue — abandoning a signal account materially reduces vendor income, creating financial pressure to maintain transparency. Second, the MetaQuotes infrastructure includes additional checks (signal-source verification, broker authentication) beyond what MyFXBook performs. Third, signal subscribers receive automatic notifications when accounts encounter issues, providing distributed monitoring that MyFXBook does not.

Limitations parallel MyFXBook: the account is verified, the EA running on it is not. Vendors can publish signals for accounts they hand-trade rather than for accounts running the EA being marketed. Buyers should cross-reference signal trade timestamps with the EA's claimed signal-generation pattern.

For the editorial verification floor, both MQL5 Signals and MyFXBook accounts qualify equivalently. EAs whose vendors publish neither — relying instead on screenshots, "verified" claims without third-party links, or backtest-only evidence — fall below the diligence floor regardless of the underlying strategy's quality. The 2026 EA market has internalised this expectation: serious vendors maintain at least one of MyFXBook, MQL5 Signals, or FX Blue accounts as a baseline trust signal.
