Mean Machine
Reviewed by Pitt Petruschke, operator. No stake in Mean Machine; receives commission from ATS and develops his own EA, Dawnbreak. Disclosure

Verdict
Grid EA on Multi-Symbol, stop logic not checked individually. No live account on record, weakest point verifiability: 5.4 out of 10.
AI-assisted mean-reversion grid by William Brandon Autry with multi-model consensus for MT4/MT5. It is still promoted but can no longer be bought on the MQL5 market.
Suits you if …
- ●Yes: you set an account stop and stick to it
- ●Yes: your account has room for several positions open at once
- !Caution: you run no second grid EA on the same markets
- –No: not for prop challenges with a daily loss limit
- !Caution: you start small, since no live account is on record

How the strategy trades
Schematic · no market dataSchematic of the Grid strategy type: it explains the process, not the outcome. No prices, no real market data, no performance of Mean Machine.
How it works
- The EA buys and lays a grid below: one more position every 20 pips, always 0.10 lots.
- All positions share one target just above the average price.
- Because they are all the same size, the average sits exactly in the middle: halfway back is break-even, and 5 pips above that the whole basket closes in profit.
- What the animation does not show: if price keeps running against the basket, the floating loss grows with every level – without a stop there is no built-in exit.
What we check
What we check on real grid EAs: the maximum floating loss on the live account, not the closed drawdown – and whether there is a hard stop for the whole basket.
Schematic with demonstration values: a simulated price path without prices, results in pips weighted to 0.10 lots, deliberately favourable. Not this EA’s market or settings, not a backtest and not investment advice.
Design & risk
Mean Machine by William Brandon Autry is a Grid EA on Multi-Symbol (MT4/MT5), sold directly by the vendor. When price runs against the basket, the EA adds further positions. All positions close together once the average is in profit. That gives a calm curve while the market ranges; a trend that runs through takes back many small wins at once. Whether there is a hard stop per position we have not checked individually. You buy the vendor default; risk frame and setfile are up to you.
Stop logic not checked individually
If a trend runs out of the range, the open loss grows with every step. Whether the EA sets a hard stop per position we have not checked individually. Set an account stop, for example with an external drawdown guard.
Rather without a grid? The best-graded EAs without one, wherever they are sold:

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.
How good is Mean Machine?
Our grade: 5.4 out of 10. It comes from six criteria: risk control, verifiability, transparency, value for money, usability and broker independence. The sub-grades are computed by our data formula; criteria, weights and caps are the same for every EA, whoever sells it, and no EA vendor pays for ratings. The full calculation with every threshold is in our methodology.
Is there a verified live track for Mean Machine?
No — we hold no live account for this specific EA that we could view. What we can place is the design and the vendor context. Without a documented account the evidence mark is low; how we weight that is in our methodology.
Changes to this review
- Second review by an AI agent (different model, blind): 2 of 6 criteria agree. Differences:
- Risiko-Kontrolle: Zweitprüfung 4,0, unsere Bewertung 6,8. Die Grid-Bauart kann Positionsrisiken bei anhaltenden Gegenbewegungen aufbauen, und ein harter Stop sowie belastbare Risikobegrenzungen sind nicht dokumentiert.
- Transparenz: Zweitprüfung 4,0, unsere Bewertung 6,0. Die Kurzbeschreibung nennt Grid, Mean Reversion und KI-Konsens, liefert jedoch keine prüfbare Dokumentation zu konkreter Logik, Parametern, Risiken oder Kontohistorien.
- Preis-Leistung: Zweitprüfung 5,0, unsere Bewertung 6,8. Da kein Preis und kein klarer aktueller Lieferumfang genannt werden, ist das Preis-Leistungs-Verhältnis nicht verlässlich bewertbar.
- Bedienbarkeit: Zweitprüfung 5,0, unsere Bewertung 7,0. Die Unterstützung von MT4 und MT5 ist grundsätzlich zugänglich, aber fehlende Angaben zu Installation, Setfiles, Dokumentation und Support begrenzen die Einschätzung.
