Petko AleksandrovFree doesn’t usually mean good in trading software. That’s just the reality. But every so often, a free trading robot comes along that genuinely holds its own against paid alternatives, and the Dark EA series from the MQL5 marketplace is probably the best current example of that.
At Algo Trading Space, we’ve spent considerable time backtesting, demo testing, and live trading several of these free expert advisors. This guide covers five of them: Dark Venus, Dark Mimas, Dark Dione, Dark Moon, and Dark Rea. We’ve also included details on our Free EA Campaign, where paid EAs are available at no cost.
Every review here is grounded in real testing. Real accounts. Real results tracked on FXBlue. Where the numbers were good, we say so. Where the risks exist, we say that too.

How We Test Free Expert Advisors
Before getting into the individual reviews, it’s worth explaining the testing process, because it directly affects how much weight to give the results.
Step 1: MQL5 marketplace review
We start by checking ratings, review count, and developer history. A highly rated EA with hundreds of reviews from a developer with multiple successful products is worth more attention than an anonymous upload with five reviews.
Step 2: Backtesting with real-tick data
We run backtests using the “every tick based on real ticks” model in MetaTrader wherever possible. This produces more accurate results than the every-tick artificial model, which many developers use to make their products look better than they are.
Step 3: Settings experimentation
Default settings rarely produce the best outcome. We run multiple backtests across different inputs, timeframes, and risk levels before settling on a configuration worth testing live.
Step 4: Demo before live
We open a demo account matching the intended live account size before committing real money. If demo results align with the backtest, we move forward.
Step 5: FXBlue verification
Every live account is connected to FXBlue for independent, third-party tracking. Links are shared publicly so anyone can monitor performance in real time.
One more thing worth stating clearly: for grid-based trading systems specifically, we apply extra caution. Grid EAs can produce clean equity curves for months and then face a single severe drawdown. That risk is real, and we flag it for every applicable EA in this guide.
1. Dark Venus: Our Top Free EA Pick, Now With VIP Set Files
Dark Venus is currently sitting near the top of the MQL5 marketplace free expert advisors list, and that rating reflects genuine trader interest. We tested it previously, set it aside for a period, then returned to it in 2025 with considerably more experience trading the broader Dark EA series.
The result: after running many backtests across different settings, we found configurations that look promising across multiple account sizes. The EA trades EUR/GBP on the M15 timeframe and uses a grid system with an optional martingale component, though we disable the martingale by default.
Platform compatibility: MetaTrader 4 and MetaTrader 5
What the Backtests Showed
We tested four separate configurations: two for a $10,000 account and two for a small $200 account. All tests ran from January 2024 with a 10ms execution delay.
| Configuration | Account Size | Net Profit | Max Drawdown |
| Fixed lots (0.4) | $10,000 | ~54% | Under 20% |
| 3% risk per trade | $10,000 | ~38% | ~12% |
| Fixed lots (0.01) | $200 | ~67% | ~23% |
| 3% risk per trade | $200 | ~50% | ~14% |
The key adjustments we made: changing the take profit from the default 50 to 100, and switching the grid from martingale mode to fixed lot mode. That second change is important. The EA still trades a grid, but adds positions at the same lot size throughout rather than doubling or tripling exposure as a trade moves against it. It’s meaningfully safer, and the backtest numbers support that.
For broker selection, we use AAP, which is well-regulated in Australia and offers tight EUR/GBP spreads. Spread quality matters considerably for this EA given how it enters and manages positions across the grid.
Dark Venus: Pros and Cons
Pros:
- Consistently near the top of the MQL5 free EA rankings at the time of writing
- Four tested configurations covering both large and small accounts
- Martingale component can be disabled for a safer grid approach
- The percentage-based risk option gives flexible lot sizing
- Currently being traded live by our team
Cons:
- Still a grid system; a sustained adverse move on EUR/GBP can produce meaningful drawdowns
- Best set files require VIP Club membership rather than being freely available
- Default settings are not what we’d recommend for live trading; experimentation takes time
- EUR/GBP is less liquid than major pairs; spread sensitivity is higher than on EUR/USD or similar
2. Dark Mimas: A Free EA That Trades the DAX
Most free expert advisors focus exclusively on forex pairs. Finding one that works reliably on an index is genuinely uncommon, which is what makes Dark Mimas worth discussing separately.
The EA was designed for EUR/USD, GBP/USD, AUD/CAD, and similar forex pairs. No mention of indices anywhere in the official documentation. But after running backtests across different assets, results on the DAX (German 40) came back surprisingly strong.
Platform compatibility: MetaTrader 4 and MetaTrader 5
Backtesting on a $200 Account
We tested Dark Mimas on the German 40 over approximately five years (January 2021 to August 2025) using default settings of 0.01 lots, $200 deposit, 1:100 leverage, and the every-tick real-tick model for accuracy. The equity line was notably smooth, with no extended drawdown periods and relatively quick recoveries each time.
Results at 0.01 lots:
- Net profit: approximately 90% on a $200 account
- Maximum drawdown: 28%
- Short trade win rate: ~93%
- Long trade win rate: slightly higher
At 0.02 lots, profits roughly doubled but drawdown increased to around 45%. We went with 0.01 for the live account. For most traders, especially on a small account, keeping drawdown manageable matters more than chasing higher returns.
Setup Notes
We used Eightcap for this test, which offers DAX (German 40) spreads starting from 1.5 pips. One important setup step: DLL imports must be enabled in MetaTrader’s expert advisor settings before placing the EA on any chart. Without that, no trades will open, even during backtesting. This applies to all Dark EAs, not just Mimas.
The EA is available free on the developer’s website, where you receive 10 flexible licenses rather than the single license available through the MQL5 marketplace. That gives you room to test across multiple accounts or assets simultaneously.
Dark Mimas: Pros and Cons
Pros:
- Works on indices, which is uncommon for a free trading robot
- Default settings are usable without adjustment; set file is included with the EA
- High win rates on both long and short trades in backtesting
- Five-year real-tick backtest with no account blow at 0.01 lots
- 10 free flexible licenses available via the developer’s website
Cons:
- Not officially designed for the DAX; trading it outside the intended asset scope adds uncertainty
- 28% drawdown may be uncomfortable for some traders even on a live account
- Getting 10 licenses requires registering through the developer site rather than MQL5 directly
- No long-term live verified track record available yet at time of writing
3. Dark Dione: A Free EA Pushed Beyond Its Design
Dark Dione is primarily designed for EUR/USD, GBP/USD, and NZD/USD. The developer mentions silver compatibility, but our own backtesting couldn’t find settings that worked consistently there.
What did work surprisingly well: gold. And also EUR/USD with custom settings. We spent considerable time experimenting with inputs for XAU/USD on the M1 timeframe, and the results exceeded what we expected from a free tool.
Platform compatibility: MetaTrader 4 and MetaTrader 5
The Gold Setup and Live Results
Backtest parameters: XAU/USD on M1, 19 months of data (beginning of previous year to recent), $200 account, 1:100 leverage, every-tick real-tick model.
Key settings changed from default:
- Take profit: set to 100 pips
- Money management: enabled at 2% risk per trade
- Max lot: capped at 0.02 to prevent the grid from building excessive exposure
- Grid management coefficient: adjusted to 0.5
- Minimum distance for grid orders: increased to 1,750 (significantly higher than default)
- Stop loss: disabled
Backtest results: 55% net profit over 19 months on a $200 account, with a maximum drawdown of approximately 31%.
Six days into live trading on a $200 FP Markets account, the EA produced $97 in net profit with a 2.47 profit factor. Weekly return of approximately 50%. That pace won’t hold indefinitely, and the volatility that came with those results was notable. We added a monetary stop loss set at 50% of current account value as a safeguard, which we adjust upward as the account grows.
The EUR/USD set file we created separately showed a 150% net profit on $200 over the same 19-month period, with a 33% drawdown. That’s also being considered for a second live account.
Broker Used
FP Markets on a raw account for XAU/USD. Raw account spreads on gold average around 12 cents, which is essential for a grid system trading on M1 timeframes. A standard account with wider spreads would significantly reduce the edge on this setup.
Dark Dione: Pros and Cons
Pros:
- 92% short win rate and 96.4% long win rate in gold backtesting
- Highly customisable inputs allow adaptation to assets beyond the intended design
- Strong early live results: $97 net profit in 6 days on a $200 account
- 10 flexible MT4/MT5 licenses available free via the developer’s website
- EUR/USD set file also available, showing 150% gain in backtesting on the same $200 base
Cons:
- Grid system with M1 timeframe means the EA can be very active and volatile
- $200 is the absolute minimum; a $1,000 account would be more comfortable in practice
- 31% drawdown in backtesting requires a high tolerance for equity fluctuation
- Monetary stop loss must be set and monitored manually as the account grows; not automatic
- Not designed for gold; using it there requires significant settings work before going live
4. Dark Moon: Promising Backtest Results on EUR/USD
Dark Moon comes from the same developer as Dark Rea and several other well-regarded free EAs. At time of testing, it had 265 reviews on the MQL5 marketplace and a high overall rating, which is a reasonable signal before investing time in deeper testing.
The EA is recommended for EUR/USD, GBP/USD, NZD/USD, and USD/CHF. We focused our testing on EUR/USD.
Platform compatibility: MetaTrader 4 and MetaTrader 5
Finding the Right Settings
This is where it gets honest. The first backtest we ran, on the default settings at M15 for one year, looked excellent for most of the period and then blew the account in July. That’s a familiar story with grid systems on default inputs. The default is rarely where you want to be.
After experimenting, we settled on a custom set file using the H1 timeframe on EUR/USD with a $200 deposit and 1:800 leverage on a BlackBull Markets demo account.
Backtest results with the custom set file (one year):
- Gross profit: $233 on a $200 starting balance
- Net profit: $130, approximately 65%
- Maximum balance drawdown: 10%
- Maximum equity drawdown: 40%
The 40% equity drawdown is notable. On a live account with sufficient margin available, the position recovered cleanly. For a prop firm challenge, this would almost certainly breach max drawdown rules, so we wouldn’t recommend it for that purpose.
Demo to Live Process
We opened a $200 demo account on BlackBull Markets, matched the settings exactly to the backtest configuration, and let it run. BlackBull is well-regulated, offers competitive spreads across major pairs, and supports 1:500 leverage on live accounts, which is useful when running a grid system that needs margin headroom.
The process: create demo account, download Dark Moon from MQL5 or the developer site, enable DLL imports in MetaTrader settings (required for all Dark EAs), drag the EA onto the EUR/USD H1 chart, load the set file, verify the inputs match the backtest configuration. Then wait.
If demo performance aligns with the backtest results, the plan is to move to a live $200 account with identical settings.
Dark Moon: Pros and Cons
Pros:
- 265+ reviews and high rating from a developer with multiple successful EAs
- 65% net profit in one-year backtest on a $200 account
- 10% maximum balance drawdown is manageable on a live account
- Straightforward setup process with clear settings documentation
- Available free on MQL5 marketplace and via the developer website with 10 licenses
Cons:
- Default settings can blow a small account; custom set file is essential
- 40% equity drawdown during backtesting is high and requires strong risk tolerance
- Not suitable for prop firm challenges due to drawdown characteristics
- H1 timeframe means slower trade frequency; results build gradually rather than quickly
- Demo-only at time of writing; live results not yet verified
5. Dark Rea: Steady Returns on Darwinex Zero
Dark Rea is a free expert advisor from the same developer as Dark Venus and Dark Moon. We’ve been trading it for approximately six weeks in a Darwinex Zero account, and the equity curve has been one of the more consistent we’ve seen from a free EA.
Platform compatibility: MetaTrader 4 and MetaTrader 5
Live Account Performance
The EA was initially set up on EUR/USD, then switched to EUR/CHF early on. The reasoning: EUR/CHF is a less volatile pair, which suits a grid system better in terms of avoiding the large, fast moves that can create severe drawdowns.
Live results after six weeks:
- Total profit generated: $646 in the account
- Monthly return: just under 4%
- Profit factor: 3.12
- Win rate: 70% winners, 30% losers
The equity curve stayed close to the balance line for most of the period. There were two small drawdowns that recovered quickly, and one larger drawdown of around 4% that also recovered within a reasonable timeframe.
Why Darwinex Zero Works Well for Grid EAs
This is worth explaining, because the platform choice is deliberate rather than arbitrary.
Darwinex Zero is not a standard broker account. You pay a monthly fee of €38 (after a signup fee) and receive €100,000 in virtual funds to trade. Any profit earned in the DARWIN generates a performance fee for you: 15% in the silver phase, with the potential for investor allocation as your rating improves.
For a grid system, this setup is practical. If the account blows due to an extreme drawdown, the consequence is restarting the account and paying another monthly fee, rather than losing your own capital. That changes the risk calculation meaningfully. It’s also backed by Darwinex, a fully regulated broker based in Europe, which is notably different from most prop firms.
Note: the grid option must be configured carefully within Darwinex Zero, as the platform’s risk engine prefers straightforward open-and-close strategies. We trade Dark Rea with lower risk settings to stay within those preferences.
Dark Rea: Pros and Cons
Pros:
- Profit factor of 3.12 after six weeks of live trading; one of the stronger results from a free EA
- Consistent equity curve with small, recoverable drawdowns
- Well-suited to Darwinex Zero structure, reducing personal capital at risk
- EUR/CHF pair reduces volatility compared to major dollar pairs
- Set file shared as a free download; no membership required
Cons:
- Grid system; a sustained move against open positions can produce a larger drawdown than the track record currently shows
- Darwinex Zero requires a monthly fee and time to progress through calibration and silver phases before earning performance fees
- 70% win rate means 30% of trades close at a loss, which creates equity dips that require patience
- Relatively short live track record at time of writing; six weeks is early-stage data
Free EA Campaign: Get Paid EAs at No Cost
Beyond the five free expert advisors reviewed above, Algo Trading Space runs an ongoing Free EA Campaign where traders can access paid EAs without paying for them.
The campaign is available at: algotradingspace.com/free-ea
This is worth knowing for traders who want to go beyond what’s freely available on the MQL5 marketplace. The campaign includes EAs that would otherwise require a purchase, available through specific participation requirements outlined on the page.
If you’re building out a portfolio of trading systems across different assets and timeframes, this is a practical way to test more tools without a high upfront cost.
Frequently Asked Questions
What are free expert advisors and where can I find them?
Free expert advisors are automated trading robots available at no cost, primarily through the MQL5 marketplace under the “free” filter in the expert advisors section. All five EAs reviewed in this guide are free and available there.
For some, getting the EA directly from the developer’s website is a better option since it typically includes 10 flexible licenses for MT4 or MT5, compared to the single license available through MQL5. Algo Trading Space also runs a Free EA Campaign at algotradingspace.com/free-ea, where certain paid EAs are available at no cost.
Are free MetaTrader expert advisors reliable enough to trade live?
Some are, and some aren’t. The key differentiator is the testing process behind them. Free EAs on MQL5 range from highly rated systems with hundreds of verified reviews to low-quality uploads with no meaningful track record.
At Algo Trading Space, we run backtests using real-tick data, demo tests with matched account sizes, and only move to live accounts after results are consistent. The Dark EA series has shown genuine live performance across multiple accounts, which is why we actively trade several of them.
Do these EAs work on MetaTrader 4 or MetaTrader 5?
All five EAs reviewed here, Dark Venus, Dark Mimas, Dark Dione, Dark Moon, and Dark Rea, are compatible with both MetaTrader 4 and MetaTrader 5. When downloading from the developer’s website rather than MQL5, both MT4 and MT5 versions are typically included with the license.
One universal requirement across all Dark EAs: DLL imports must be enabled in MetaTrader’s expert advisor settings before the EA will run. Without this, no trades will open, even during backtesting.
What is a grid trading system, and what are the risks?
A grid trading system opens multiple positions at set price intervals rather than entering a single trade with a fixed stop loss. When the market moves in the right direction, the positions close in profit. When it moves against them, more positions open at lower prices, waiting for a recovery.
The risk is a sustained one-directional move that builds a large floating loss before a recovery occurs. Grid systems can produce very clean equity curves in range-bound or gradually trending markets, then face severe drawdowns when conditions change. Always set a maximum loss limit and monitor actively.
What is the minimum account size for these free EAs?
Most of the EAs reviewed here were tested on $200 accounts, which is the practical minimum for most of them. Dark Dione is the exception: while we ran it on $200, a $1,000 account would be considerably more comfortable given its activity level and drawdown characteristics on the M1 timeframe.
Dark Mimas and Dark Moon are more forgiving at the $200 level. Regardless of account size, starting on a demo account with a matching balance and leverage before going live is strongly recommended.
Can I use these free expert advisors on prop firm challenge accounts?
Generally, we would not recommend it. Most of these EAs use grid systems that can produce equity drawdowns exceeding the 5% to 10% daily and overall loss limits that prop firms enforce. Dark Moon’s backtest showed a 40% equity drawdown, which would immediately fail most challenges.
Beyond the drawdown issue, many prop firms restrict the use of third-party EAs or EAs used by multiple traders simultaneously. If you want to use EAs for prop firms, look for systems specifically designed and optimised for challenge rules rather than repurposing free general-purpose EAs.
What is the Algo Trading Space VIP Club?
The VIP Club is a membership that provides access to tested set files, advanced configurations, and research that isn’t shared publicly. For Dark Venus specifically, the four set files we developed and currently trade are only available through the VIP Club.
This is because the settings took significant time to develop through extensive backtesting, and sharing them exclusively through membership ensures members receive maintained, updated configurations rather than a one-time public release. Other EAs may have set files shared freely, as is the case with Dark Rea.
How do I set up a free EA on MetaTrader for the first time?
The basic process is consistent across all Dark EAs: download the EA from MQL5 or the developer website, place the file in the MetaTrader experts folder via File, then Open Data Folder, then MQL5, then Experts. Restart or refresh MetaTrader.
In the platform settings under Tools, Options, Expert Advisors, enable both algorithmic trading and DLL imports. Open a chart on the intended asset and timeframe, drag the EA from the Navigator panel onto the chart, load your preferred set file via the Inputs tab, and click OK. The EA will begin trading when the next signal conditions are met.
Final Thoughts
Free expert advisors are often dismissed without a fair hearing. That’s understandable given how many poor-quality EAs flood the MQL5 marketplace. But the Dark EA series genuinely earns its rating, and the five reviewed here represent some of the more interesting options available at no cost.
Dark Venus leads for traders who want a tested, team-backed setup with ongoing support through the VIP Club. Dark Dione has shown the strongest early live results, though it carries the most volatility. Dark Rea is our pick for longer-term, lower-stress running on Darwinex Zero. Dark Mimas fills a gap for index traders that most free EAs ignore. Dark Moon sits in a sensible middle ground for forex trading on a small live account.
And if you want access to paid EAs without the cost, the Free EA Campaign at algotradingspace.com/free-ea is worth checking before spending money on any trading software.
Start on a demo. Test with real-tick data. Move to live only when the results give you a genuine reason to.
Trade safe.
