Dark Algo MT5 Review: PF 2.08, Max DD 35.05%

Dark Algo MT5 Review — PF 2.08 / Max DD 35.05% Under the Same Conditions as Our EAs (2020–2024, Real Ticks)

This article reports our backtest of Dark Algo MT5, an EA sold on the MQL5 Market (MQL5 product page; listed price $399 as of Oct 5, 2026), run under the same conditions we use for our own EAs. All figures are our own measurements. No vendor images or vendor performance claims are reproduced.

Test Conditions (Full Disclosure)

Period, initial deposit, leverage and tick data are identical to our own EA tests. Only the symbol and timeframe differ.

Results

All four years were positive (table below). When each year was run from $10,000, the max DD within the year ranged from 33.52% to 45.82%.

Year-by-Year Results (with Max DD)

Each year was run separately starting from $10,000 (2020–2023, all other conditions the same). Because capital does not compound across years, the yearly totals do not match the full-period figures.

Comparison with Our EAs (Same Conditions)

On Oct 11, 2026 we re-ran our own EAs (the files we distribute, default settings) with the same period, deposit, leverage and real ticks. The Dark Algo MT5 figures come from the same measurement as the comparison table in our EA Lab (the own-EA rows in the EA Lab still include values from before this re-run).

Because the symbols and timeframes differ, this does not show which EA is better in the same market. Net profit depends heavily on how lot size is set (fixed or compounding), so please focus on PF and max DD. Max DD uses the same definition for all rows (largest equity decline).

Under the same conditions, PF was 2.08 for Dark Algo MT5 and 1.82 for DONCHIAN ENGINE; max DD was 35.05% and 10.33%; trades were 628 and 281.

Limitations of This Test (Please Read)

• Dark Algo MT5 was tested on M15. This may differ from the vendor's recommended timeframe and settings. We plan to re-test it on the recommended timeframe with a different tick source and will add the results here.
• The ticks are Dukascopy data. Spreads and execution differ between brokers, and so do results.
• The build date of Dark Algo MT5 (Feb 5, 2026) is later than the test period. Our EAs were also built after the test period. For both, results in this period do not indicate future performance.
• We tested the version available at the time. Later updates have not been tested.
• Backtests do not guarantee future profits.

Summary (Facts Only)

• From Jan 2020 to Feb 2024 on EURUSD M15 with real ticks and default settings, Dark Algo MT5 recorded PF 2.08, max DD 35.05%, 628 trades and net profit of +$26,141.24.
• Under the same conditions, PF was 2.08 for Dark Algo MT5 and 1.82 for DONCHIAN ENGINE; max DD was 35.05% and 10.33%; trades were 628 and 281.
• If you are considering a purchase, we recommend running the MQL5 demo in the Strategy Tester under conditions close to your own account and checking the max DD and year-by-year results.
