Mean Machine Review
AI-assisted mean-reversion grid with multi-model consensus, still promoted on the platform — but no longer purchasable on the MQL5 market. Its track (+103%, 28.3% drawdown) is therefore historical. We do not rate a product you cannot buy as a recommendation.

What Mean Machine is
Mean Machine by William Brandon Autry is a grid EA on Multi-Symbol (MT4/MT5), sold via the vendor directly. We classify it independently — by strategy risk, verified live track, transparency and value, not by vendor promises.
Live results & track record
Im MQL5-Market nicht mehr kaufbar (Stand 22.09.2026). Der Track 2025 to 2026 (+102.85%, 28.25% Drawdown) bleibt historisch einsehbar, ein Bezug ist aber nicht mehr möglich. The crux here: there is no continuous, publicly verifiable live account for this EA that we could read ourselves. An equity curve from backtests or screenshots says little about real money — slippage, spread and execution are missing. Without a verifiable account we treat every return claim with scepticism, and the rating stays deliberately cautious.
Strategy & risk
The grid approach sets the risk profile. Grid/martingale systems often show a suspiciously straight equity curve — losses are absorbed by averaging in until one trend blows up the basket. A too-smooth curve here is a warning sign, not a seal of quality. From the vendor you buy the vendor setting — a hard risk cap (parameters or an external drawdown guard) is on you to set.
Cost & usability
You buy the vendor version without calibration — risk cap, broker choice and setfile are on you. Delivered by e-mail against your account number, licence bound to accounts — direct sellers rarely offer refunds.
Who it is (not) for
Suitable for traders who check the live signal carefully themselves and run the EA with their own hard risk cap and budget it as *one* building block. Not suitable for small accounts without a buffer or for anyone who mistakes a smooth backtest curve for a guarantee.
Verdict
Mean Machine lands at 2.6/5 — better avoided in its current form. Check the MQL5 live signal carefully before buying.
Frequently asked questions
- Which markets does Mean Machine trade?
Multi-Symbol. Several instruments only spread risk while they do not share a driver — correlated pairs go down together when it matters.
- Which platform does Mean Machine run on?
MT4/MT5. Continuous operation needs a VPS, because a sleeping machine leaves open positions unattended: VPS providers compared.
- Does Mean Machine use grid or martingale?
Yes — the design is Grid. That means further orders are added when price runs against an open position, and there is usually no hard per-trade stop-loss. Such systems stay quiet for a long time and then take the loss all at once. How that works and how to spot the dangerous variant is in our guide to grid and martingale EAs.
- Is Mean Machine any good?
Our grade: 2.6 out of 5, traffic light red — avoid. It comes from six criteria, weighted most heavily towards the verified live track record and strategy risk. We rate from real accounts, not vendor backtests, and no EA vendor pays for ratings — the weighting is public in our methodology.
- Is there a verified live track for Mean Machine?
No — we hold no independently checked live track for this specific EA. What we can place is the design and the vendor context. Without a documented account we rate conservatively; how we weight that is in our methodology.
