1,589 baskets closed in profit. Then one didn’t. A new $1,000 account, opened on October 1, had $57 left the next morning. That’s the version you can buy today, on its default settings. This is the Quantum Queen EA review I wanted to read before paying $1,199.99 for it, so I built it myself, every number with a date and a source.
Quick note first: I build EAs too, gold included, at DoItTrading. I have no relationship with the developer of Quantum Queen X. Everything below is a historical test, not a forecast, and it’s not financial advice.
What you’re actually buying
The listing calls it an elite trend-following grid with twelve strategies. In my tests, ten of them trade. One never opened a trade in almost seven years, and there is no number eleven.
- Minimum $500 at 1:500 leverage. VPS mandatory.
- Sold as “plug and play”, with a “fully optimized default configuration”.
- The listing describes four sets: medium risk, low risk and two broker presets. The default set inside the EA isn’t on that list. Its label says “High Risk”.
- And one line worth remembering: “Capital preservation remains one of the core principles of the system.”
Here’s how a grid works. When price moves against it, it doesn’t close the trade. It adds another one, and another. When price comes back, the whole basket closes in profit. I checked every trade it opened in my tests: 2,767. Not one had a stop loss. The EA decides when to close.
How I tested it
I used the Quantum Queen X demo from the MQL5 Market. No decompiling: I only read its trades and its logs. Its own settings still call it “Quantum Queen MT5 v4.4 (31/07/2026)”.
- MT5 Strategy Tester, XAUUSD on Axi, leverage 1:500, default settings unless I say otherwise. Affiliate link; I may earn a commission if you open an account through it.
- Real ticks from August 2025, 1-minute OHLC for 2020 to October 2026.
- Every basket rebuilt from the EA log and reconciled to the cent with each tester report.
The night of October 6
October 6, in the evening, strategy one opens a buy. Gold keeps falling, so it buys again. And again. By morning: nineteen buys, an average price of 4,160, and gold at 4,136. From the first buy, that’s a drop of about one percent. Not a crash. One percent.
The account runs out of margin and the broker closes everything. A new $1,000 account ends with $57.
This wasn’t only my tester. People running it were posting in the public product chat that same night. One wrote “step ten” when my tester had nine buys. Later, “step seventeen”, when my tester had fifteen. Then: “4161 is the TP now”. My tester’s average price was 4,160.7. Different broker, same night.
On the product page, a review from October 7 says the reviewer’s real account had $2,500 on October 1 and $20 after that night. And the developer wrote in the product’s own chat: “Yes, we lost a grid two days ago.”
Was it the settings?
That was my next question, so I tried every option it gives you on that same night, with a new $1,000 account:
- All five presets lost between 94% and 96%. One of them is called “Low Risk”. The strategy that opened that basket is labelled “Low Risk” too.
- Every automatic risk level, from very low to very high, the minimum lot and a 300 ms execution delay: between $24 and $57 left.
- Its own drawdown cut at 15%: it closes that basket at nine buys, takes a $152 loss and keeps trading. The account finishes the test at $878.
That drawdown cut comes switched off. Nine days before that night, a buyer had asked in the comments whether, without drawdown protection, one long move could wipe out the whole account. After the losses, the developer answered reviews by pointing to the DD Control mode and the low-risk presets. In my test, the Low Risk preset lost 94% that same night.
What the 99.9% win rate hides
I ran it from 2020 to now: 1,590 baskets, 1,589 closed in profit. That’s 99.94%. The average win was less than half a percent of the account. The one loss was 104% of it.
On real ticks, from August 2025, a $1,000 account grew for fourteen months: 451 winning baskets. Then one basket lost $12,173 and took everything it had made. The test ended at $717.
A single backtest is one path, so I also ran my stress test: 1,000 alternative histories rebuilt from its own baskets, each basket counted as one trade. If you want the method, I explained it in Monte Carlo simulation for trading.
| Starting account | Histories where the account disappears |
|---|---|
| $1,000 | 1 in 5 (20.4%) |
| $500 (the listed minimum) | About half (49.3%) |
Any prop firm daily loss limit would have been hit long before the broker’s stop out. If you were thinking of running a grid on a challenge, read the rules first; I went through what the FundedNext EA add-on allows, and programs like Axi Select only allow a third-party EA for generating signals, with trades placed manually.
The history: the signal, the price and the new page
The original Quantum Queen had 4.97 stars from over 400 ratings. In July, buyers reported blown accounts and that page stopped selling it. Days later, Quantum Queen X went live on a new page, starting from zero reviews. Its settings still call it Quantum Queen, and its website link points to the old page.
The signal. Both listings linked the same live signal. After the October loss, the developer still pointed to it: “more than 30 months of live trading and over 5,000% growth”. Its starting deposit was $100, which is how a signal shows thousands of percent. In April the page showed a 21% drawdown. In October, 85% and a balance of zero. A zero balance can also mean the money was taken out, so I won’t call that a blow-up. When I checked, the page said it had probably been deleted. It was also for sale, at up to $999 a month, with zero subscribers in every snapshot I found.
The price. Every Quantum Queen listing had a line saying the price would increase with every ten purchases. The archive shows something else:
- August 2024: $599, with a final price of $999.
- May 2025: $999. A week later, the final price in that same line changed from $999 to $1,999.
- July 2025: $1,299.
- August 2025: $999 again, with a “25% off” banner. A discount on a price that, by its own line, only goes up.
The new page. Quantum Queen X started at five stars, with 31 reviews in August. On 21 October it showed 4.14. On October 7, the developer pointed buyers who found it too aggressive to two other EAs from the same seller. Nine days later came the announcement of the next gold EA, Quantum Valhalla, on a brand-new page; the launch post says “No Grid. No Martingale.” That’s twice in three months: a bad night, then a new page that starts from zero.
I can’t tell you why any of this changed. I can tell you what changed, and when. Check every link above yourself.
What it does well
- Its strategies work. Each of the ten made money on its own at the minimum lot.
- Its win rate is real. The 77% it shows matches my test (77.8% of trades from 2020 to 2026).
- It comes with a drawdown cut. Switched on at 15%, it saved the account on the worst night.
After the loss, the developer described it as “a high-risk, high-reward system”. The listing says capital preservation. Both sentences are about the same EA.

Watch the full test: in Quantum Queen X Review: I Tried to Break It I go through that night buy by buy, with the charts.
My score: 3 out of 10 on its default settings
The engine wins almost every basket. The default settings can lose almost the whole account in one night, on a one percent move: no stop loss, drawdown cut switched off, up to a hundred orders.
If you still run it, turn on the drawdown cut and take your profits out as you make them. The money you leave in the account is the money the next bad night takes. One buyer put it well in the reviews: they had always made regular withdrawals and secured their profits, so in the end they were still in profit.
Before you buy any grid EA, check four things
- The price history. Open the listing on the Wayback Machine and compare it with the “price only goes up” line.
- The live signal’s starting deposit, not its growth. Thousands of percent from $100 tell you very little about your account.
- A stop loss on the orders. If there isn’t one, find the drawdown cut and switch it on.
- Its worst day, with real ticks, on your own account size. Here’s how to backtest an EA on MT5 without fooling yourself.
And before you buy a new EA, find the page it came from and read its worst reviews. My previous test, The Gold Reaper MT5 review, went the other way: it held up.
A 99% win rate is where the questions start. Not where they end. Next I’m breaking My AI Gold. Want a different one? Tell me, and get the next test first: join the DoItTrading newsletter.

Frequently Asked Questions
Is Quantum Queen X worth it?
On its default settings, I give it 3 out of 10. The engine wins almost every basket, but there is no stop loss and the drawdown cut comes switched off, so one night on October 6, 2026 took a new $1,000 account to $57 in my test.
Does Quantum Queen X use a stop loss?
Not in my tests. I checked all 2,767 trades it opened and none had a stop loss. It’s a grid: it adds trades when price moves against it and closes the whole basket in profit when price comes back.
Which Quantum Queen X setting is safest?
In my test, only its own drawdown cut saved the account: set to 15%, it closed the October 6 basket at nine buys with a $152 loss and the account finished at $878. All five presets lost between 94% and 96% that night, and every automatic risk level left between $24 and $57.
What about the Quantum Queen live signal (Myfxbook or MQL5)?
The signal both listings linked is an MQL5 signal that started with a $100 deposit. It showed a 21% drawdown in April 2026 and 85% with a zero balance in October 2026, and when I checked, the page said it had probably been deleted. A zero balance can also mean withdrawals, so I don’t call it a blow-up.
What is the Quantum Queen X price?
$1,199.99 when I checked on 21 October 2026. The original Quantum Queen listing said the price would go up with every ten purchases, but the archive shows it at $999 with a “25% off” banner in August 2025, after $1,299 in July.
Are you affiliated with the developer?
No. I build and sell my own EAs at DoItTrading, including a gold strategy, and I said so at the start of the review.
