From Download to Live Trading in Under 15 Minutes

Getting Dark Mimas running is straightforward — here is the full journey from first download to your first automated trade signal.
1
Download From Dark EAs

Download From Dark EAs

Head to darkeas.com/free-eas and download the Dark Mimas EA file — EX4 for MetaTrader 4 or EX5 for MetaTrader 5. No registration or payment is required; the download is completely free. You may also want to download the Dark Oscillator indicator separately from the MQL5 marketplace (product IDs 64139 for MT4 and 64140 for MT5) so you can visually confirm signals on your chart as the EA trades. Joining the developer's Telegram channel at this stage gives you access to real-world configuration files shared by other users before you even open MetaTrader.
2
Install on MetaTrader

Install on MetaTrader

Copy the EA file into the Experts folder of your MT4 or MT5 data directory, then restart the platform. The EA will appear in your Navigator panel under Expert Advisors. Drag it onto the chart of your chosen instrument — EURUSD M15 is a popular starting point — and enable the Allow Algo Trading button in the terminal toolbar. If you downloaded the Dark Oscillator indicator separately, install it in the Indicators folder so signal arrows are visible on the chart alongside the EA's activity.
3
Configure Risk Settings

Configure Risk Settings

Open the EA parameters and set your Magic Number (a unique ID for the EA's orders to avoid conflicts with other EAs), Max Spread limit, and money management settings. Enable the Money Management toggle and set Risk Percent to 1–2% for a conservative start. If you prefer manual lot sizing, disable money management and input a fixed Lots value. Set Max Lot Amount to cap position size during volatile periods. New users should leave the grid disabled initially and configure a basic Stop Target to define maximum acceptable drawdown while learning the system.
4
Select Your Oscillator Strategy

Select Your Oscillator Strategy

Choose one of the six Dark Oscillator Strategies. Strategy 1 (Buy Green Arrow, Sell Red Arrow) is the most intuitive starting point for trend-following setups. Configure the oscillator period, method, applied price, and timeframe to match your chart. Apply trading hour and weekday filters to concentrate activity during preferred sessions. If you want tighter entry criteria, enable Dark Oscillator Additional Rules to combine level conditions with arrow signals simultaneously, requiring both to be true before any order is placed.
5
Monitor, Review, and Refine

Monitor, Review, and Refine

Once live, use the Show Panel option to monitor open positions, spread alerts, and grid status directly on the chart. Review performance weekly — check drawdown against your configured thresholds, note which sessions produce the most consistent returns, and adjust grid settings or risk percent accordingly. The EA's performance is heavily influenced by broker spreads, so ECN brokers with tight pricing on your chosen pairs are strongly recommended. Compare notes with other Dark Mimas users on the Telegram channel for ongoing configuration improvements.

What Is Dark Mimas EA and How Does It Trade?

Dark Mimas is a fully automatic, free Expert Advisor built around the proprietary Dark Oscillator indicator - a momentum-based oscillator that generates color-change signals and directional arrows on price charts. The EA captures those signals to enter trades on pairs like EURUSD, GBPUSD, AUDCAD, and AUDCHF, across flexible timeframes from M5 through H1 and beyond, making it unusually adaptable for a free single-product download. What sets Dark Mimas apart is the combination of six distinct oscillator strategies — ranging from arrow-based trend-following to level-breakout logic — paired with an optional grid recovery module. When a trade moves against you, the grid can layer in additional positions at configurable intervals, with four lot management modes: fixed size, lots sum, all-lots sum, or classic martingale. Each approach carries its own risk profile, and the manual is transparent about which settings demand more capital. Both MT4 and MT5 are fully supported. The EA also adapts to indices like GER40 with appropriate settings, broadening its appeal beyond pure forex traders. Trading hour and weekday filters, ATR-based grid spacing, and a built-in average trailing stop round out the feature set. Considering the zero price tag, this is a serious, configurable system backed by an active developer community on Telegram.

What You Get With Dark Mimas EA

Dark Mimas packs professional-grade trading controls into a completely free download, combining a proprietary indicator, flexible grid logic, and built-in risk management across multiple forex pairs and timeframes.
  • Trade entries are fired by the proprietary Dark Oscillator indicator, which shifts between green and red as momentum changes direction. Six distinct strategies let you trade arrow signals at color crossovers, or level-based rules where the oscillator value relative to upper and lower thresholds determines entry direction. Strategies 1 through 4 are arrow-driven; Strategies 5 and 6 use pure level logic. An optional Additional Rules parameter combines both conditions simultaneously, tightening entry criteria when needed.
  • When the initial position moves against you, the configurable grid module places additional orders at set intervals to reduce average entry price. Choose from four lot management styles — Fix, Lots Sum, All Lots Sum, or Martingale — and set minimum distance in points or ATR multiples. A distance multiplier scales grid spacing as more levels open. Grid orders can optionally respect spread, indicator, hour, and weekday conditions independently from the first-order filters.
  • Dark Mimas is recommended on EURUSD, GBPUSD, AUDCAD, and AUDCHF, but adapts to other instruments — including indices like GER40 — with settings adjustments. Supported timeframes run from M5 through H1 and all standard intervals beyond, letting you tune trade frequency to your preferred style. M5 and M15 generate higher-frequency scalp setups; H1 and above produce fewer, higher-conviction entries. Always backtest any new pair-timeframe combination before going live.
  • The built-in money management module sizes positions automatically as a percentage of account balance, with a configurable maximum lot cap preventing overexposure. Separate monetary and percentage-based stop-loss layers close all open trades if drawdown exceeds defined thresholds. An average trailing stop tracks the weighted entry point of all open positions in one direction, stepping forward as price moves favorably. Stop Target Mode can be set to first order or weighted average entry for flexible drawdown management.
  • Configurable trading hours and weekday filters let you concentrate activity during preferred market sessions, avoiding low-liquidity periods or wide-spread environments. Allow Buy, Allow Sell, and simultaneous Buy-and-Sell toggle controls shape directional exposure precisely. A Close Friday Night option reduces weekend gap risk by flattening open positions before market close, with a Forced Close variant for hard-stop situations. By default grid orders are exempt from session filters, though this can be overridden in grid settings.
  • Beyond fixed take-target points, Dark Mimas can close positions when the Dark Oscillator generates an opposing signal — useful for trend-following configurations. The ATR-based take target replaces the fixed TP with a real-time calculation (ATR value x multiplier), making exits responsive to current volatility. Breakeven and Fix-Point close modes offer additional exit styles tailored to grid basket management. A COI in-profit filter optionally restricts indicator-based closes to positive equity situations only.
  • Dark Mimas runs natively on both MetaTrader platforms, with separate EX4 and EX5 builds available from the developer and the MQL5 marketplace. This dual compatibility means you can use the same logic on legacy MT4 broker accounts and on newer MT5 hedging or netting accounts without rewriting any settings. The Expert Advisor file installs in the standard Experts folder, and parameters are identical across versions. For traders managing live and demo terminals on different platforms, this saves real time when migrating configurations.
  • The developer maintains an active Telegram channel at t.me/darktradingchannel where users share configuration files, post screenshots of live results, and ask questions. Combined with the written user manual that ships with the EA, this gives Dark Mimas a support layer most free forex robots simply do not have. New users can pull tested settings shared by experienced traders, ask questions in the channel, and verify their own setup against community benchmarks before committing real capital.

Built For Every Trading Style

Dark Mimas adapts to your experience level and trading approach, whether you are automating your first chart or running systematic research across multiple grid configurations.
Built For Every Trading Style
Complete Beginners
Complete Beginners
You have never installed an EA before — no problem. Download Dark Mimas from darkeas.com, attach it to an EURUSD M15 chart, enable money management at 1–2% risk, and leave the grid disabled. The whole setup takes under 15 minutes and the user manual explains every parameter in plain language. The developer's active Telegram channel provides real configuration examples from other users, so you are never troubleshooting alone. Start on demo for at least two weeks before switching to a live account.
Conservative Manual Traders
Conservative Manual Traders
You trade EURUSD or GBPUSD manually during European and New York sessions but miss Asian overnight setups. Dark Mimas can fill those windows automatically using trading hour and minute filters to restrict its activity precisely. Enable Allow Buy or Allow Sell only to match your directional bias from manual analysis. Keep the grid off and set a modest Stop Target, and the EA functions as a rules-based signal executor that complements your manual trades rather than competing with them.
Experienced Algorithmic Traders
Experienced Algorithmic Traders
You want a free, transparent grid platform for comparative research before committing to paid systems. Dark Mimas exposes every major parameter externally — oscillator strategy, grid step, ATR period, lot management mode, close mode — making it an effective research vehicle. Run side-by-side backtests in MT4/MT5 Strategy Tester comparing Fix versus Martingale lot management across different drawdown scenarios. The developer also provides a detailed OnTester configuration for systematic optimization runs.
Portfolio Diversifiers
Portfolio Diversifiers
You are already running paid EAs on EURUSD and want to add exposure on AUDCAD or AUDCHF without additional cost. Dark Mimas operates independently on separate chart windows using configurable Magic Numbers, so it does not interfere with other Expert Advisors on the same terminal. The Allow Order From Others Charts setting gives you precise control over whether the EA can open alongside positions from other systems, letting you manage cross-EA exposure deliberately.

Who Is Dark Mimas EA Designed For?

Best suited for:New automated traders exploring their first Expert Advisor — Dark Mimas is an ideal starting point because it is free, thoroughly documented, and backed by an active Telegram community. You can learn how an oscillator-based EA behaves in live conditions without risking capital on a paid product. Start on a demo account with Strategy 1 on EURUSD M15, run at 1% risk, and observe entries and exits before adjusting any parameters.Manual forex traders looking for session coverage automation — If you trade EURUSD or GBPUSD by hand during European and New York hours but miss Asian overnight setups, Dark Mimas can fill those windows automatically using trading hour filters. Use Allow Buy only or Allow Sell only to match your directional bias from manual analysis, keeping the grid off for clean single-position management.Algo traders researching grid mechanics — Dark Mimas is a transparent, free research platform for understanding how different lot-scaling methods affect equity curves. With four grid management modes and fully exposed parameters, you can run comparative backtests to observe how Martingale versus Lots Sum behaves across different drawdown scenarios — valuable knowledge before evaluating more expensive grid EAs.Portfolio diversifiers adding a free complement — Traders running paid EAs on EURUSD can add Dark Mimas on AUDCAD or AUDCHF without additional cost, spreading exposure across pairs with lower correlation to major dollar pairs. Configurable Magic Numbers and the Allow Order From Others Charts setting prevent interference with other systems on the same terminal.Not recommended for:Traders expecting a proven low-drawdown system — The available test data covers a GER40 configuration and showed significant drawdown risk in trending conditions. Dark Mimas is community-supported free software without live Myfxbook verification across all recommended pairs. Thorough demo testing is essential before any live account deployment.Anyone unwilling to use a VPS — The EA needs MetaTrader running continuously, especially when the grid is active. Connectivity gaps during grid recovery phases can leave positions unmanaged and expose the account to extended adverse moves. A VPS at $10–30 per month is strongly recommended.Traders uncomfortable with martingale exposure — Enabling the Martingale lot management mode compounds position sizes exponentially after losses. The manual is transparent about this risk, but it remains a meaningful danger during sustained trends that run deep against open grid positions.Prop firm challenge participants — Most prop firms prohibit grid and martingale strategies. Dark Mimas's grid module would likely violate challenge drawdown rules even on conservative settings. Verify your firm's EA policy carefully before any challenge deployment.
