Dark Mimas is a free automated forex EA using the proprietary Dark Oscillator indicator. Trade EURUSD, GBPUSD, AUDCAD & AUDCHF on MT4 or MT5.
Getting Dark Mimas running is straightforward — here is the full journey from first download to your first automated trade signal.
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.
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.
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.
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.
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.
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.

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 adapts to your experience level and trading approach, whether you are automating your first chart or running systematic research across multiple grid configurations.
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.
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.
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.
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.
From entry signal to final exit, Dark Mimas handles every decision automatically — here are the key mechanisms keeping your automated trading on track.

Dark Mimas stands out in the crowded free EA space by combining professional documentation, genuine configurability, and active community support - without asking for anything in return.
Dark Mimas costs nothing to download and nothing to use — no trial periods, no subscription tiers, and no license server checks. Download the EX4 or EX5 file and run it indefinitely. This is a rare commitment from a developer who also maintains paid products in the Dark EAs lineup, suggesting the free release is a genuine contribution to the trading community rather than a stripped-down marketing tool.
Rather than locking you into a single signal approach, Dark Mimas exposes six distinct Dark Oscillator strategies covering arrow-following, counter-arrow, immediate color-change, and level-based entries. This flexibility lets you backtest multiple approaches on the same instrument and select the configuration that fits your chosen market's volatility profile without writing a single line of code.
The user manual explains exactly how each grid lot management mode calculates position sizes, with worked numerical examples for Lots Sum, All Lots Sum, and Martingale. This transparency lets you calculate your maximum theoretical exposure before enabling any grid features on a live account — an essential step for responsible risk management that many paid EAs skip entirely.
The Dark EAs developer (msolito59) maintains an active presence on MQL5 with a verified seller profile and a library of free and paid EAs. The Telegram channel at t.me/darktradingchannel provides real-time updates and community configuration sharing. Update history on the MQL5 product page provides version tracking so you always know what changed between releases.
Dark Mimas works with any MetaTrader 4 or MT5 broker and adapts to instruments beyond its primary forex pairs — including indices like GER40 — with appropriate settings. The built-in Max Spread filter and spread alert system protect you from poor execution environments, while the ECN broker recommendation in the manual steers new users toward tighter-spread providers for better fill quality.
A full video review of Dark Mimas EA is available on YouTube, covering installation, settings configuration, and live chart behavior with the Dark Oscillator indicator applied. The developer also maintains detailed written documentation in the user manual, and the Telegram community at t.me/darktradingchannel provides real-world configuration files from active users across different pairs and brokers.

Everything you need to know about configuring, running, and managing risk with Dark Mimas EA — from first download to live trading.
Dark Mimas is officially recommended on EURUSD, GBPUSD, AUDCAD, and AUDCHF, though the developer confirms it adapts to other instruments — including indices like GER40 — with appropriate settings adjustments. Supported timeframes run from M5 through H1 and all standard MetaTrader intervals beyond. Shorter timeframes like M5 generate higher trade frequency and require tighter spread conditions to remain efficient; H1 produces fewer, higher-conviction entries with less sensitivity to execution quality. Always backtest your chosen pair-timeframe combination and run at least two weeks on demo before switching to a live account.
The grid module is optional and disabled by default — you can run Dark Mimas as a straightforward single-position EA with no recovery layers at all. If you enable the grid, you choose from four lot management modes: Fix (equal sizes), Lots Sum (incremental increases), All Lots Sum (counting both buy and sell positions), or classic Martingale (exponential multiplier after each loss). The Martingale option compounds position sizes and carries substantial account risk during extended adverse trends. The user manual includes worked numerical examples for each mode, helping you calculate maximum theoretical exposure before enabling any grid features on a live account.
No official minimum is stated by the developer — the answer depends entirely on your chosen settings. With money management at 1% risk per trade and the grid disabled, a $100–$200 deposit on a standard or cent account is sufficient for conservative exploration. If you enable the grid with martingale lot scaling, you need significantly more cushion. The available test configuration on GER40 used a $200 starting balance and experienced substantial drawdown during trending market conditions. A starting balance of $500–$1,000 on an ECN account is a more appropriate baseline when running any grid features, ensuring enough margin to handle multiple recovery levels.
Yes, with the right approach. The user manual is comprehensive, covering every setting with clear explanations and worked examples, and the developer's Telegram channel provides direct community support. Beginners should start on demo, apply Strategy 1 (Buy Green Arrow, Sell Red Arrow) on EURUSD M15, enable money management at 1% risk, and keep the grid disabled. This configuration introduces you to the oscillator entry behavior without compounding risk. The Dark Oscillator indicator can be installed alongside the EA on the chart, making it easy to follow visually as each signal fires in real time.
A VPS is strongly recommended, especially if the grid module is active. When the grid has multiple open positions, any connectivity interruption can leave trades unmanaged — potentially missing recovery entries or preventing timely exits during volatile sessions. Running from a home computer is technically possible if you can guarantee continuous operation and a stable internet connection, but most traders with serious configurations transition to a VPS within the first few weeks. VPS services suitable for MT4 and MT5 typically cost between $10 and $30 per month and dramatically improve execution reliability and uptime. The developer recommends dipgate.com as a low-latency option.
This is not recommended in most cases. Most prop firm evaluation programs explicitly prohibit grid strategies, martingale position sizing, or any form of position averaging. Even with the grid disabled, verify your firm's specific rules before running Dark Mimas on a challenge account. The EA's core oscillator-based entries without grid features are generally compatible with single-position prop firm rules, but you will need to confirm that maximum drawdown limits align with the EA's expected behavior for your chosen settings. Always test on a demo account matching the prop firm's starting balance and rules before risking your challenge fee.
Extensively. Every major parameter is externally configurable without any code changes: Magic Number, Max Spread, lots, risk percent, max lot amount, all six oscillator strategy options, oscillator period, method, applied price, up and down levels, timeframe, grid enable/disable, grid management type, minimum grid distance, distance multiplier, ATR period and multiplier, close-on-indicator mode, take target, stop target, trailing stop values, Friday close settings, and graphic display options. This level of parameter exposure makes Dark Mimas unusually flexible for a free EA and supports meaningful optimization runs in MetaTrader's Strategy Tester.
Most free EAs offer limited configuration and minimal documentation. Dark Mimas stands apart with six distinct entry strategies, four grid lot management modes, ATR-based dynamic targets, and a detailed manual with worked examples. The developer (msolito59) also maintains an active MQL5 verified seller profile with multiple products. The main limitation compared to paid EAs is the absence of live-verified Myfxbook results across all recommended pairs — the available trading data covers a specific GER40 test configuration. Backtest thoroughly and demo-test on your target pair before drawing performance conclusions for your specific setup.
Updates are delivered through the MQL5 marketplace, where the developer publishes version notes with each release. The Dark Trading Telegram channel also announces changes in real time. Because the EA is free, update cadence depends on developer availability and community feedback rather than subscription obligations. The developer is active on the MQL5 forum and responds to user-reported issues. Check the MQL5 product page (mql5.com/en/market/product/66132) for the current version and update history before installing, especially if you have been running an older copy for an extended period.
The developer explicitly recommends ECN brokers with low spreads — tight spread conditions are critical because high spreads on scalping timeframes can erode edge quickly. IC Markets (icmarkets.eu) and RoboForex are mentioned by name in the user manual. Key broker requirements: EURUSD spreads consistently below 1.0 pip during active sessions, fast execution with minimal slippage, no restrictions on automated trading or scalping, and MetaTrader 4 or MT5 platform support. For index trading like GER40, verify the broker's CFD spread and margin conditions during your target trading hours before running the EA on those instruments.
Drawdown depends almost entirely on your grid configuration. With the grid disabled and a fixed stop target, drawdown is limited to the stop loss size per trade. With grid enabled using martingale lot management, drawdown can escalate rapidly during sustained trends against your positions. The GER40 test configuration from the available data (starting balance $200) experienced a significant drawdown event in November 2025 that materially reduced account equity after a strong earlier period. Always set Maximum Monetary Loss or Percentage Loss thresholds, and ensure your starting balance can withstand at least five to seven grid recovery levels before approaching margin limits.
The Dark Oscillator is a proprietary momentum indicator developed by msolito59, available separately on the MQL5 marketplace for MT4 (product 64139) and MT5 (product 64140). It produces a colored oscillator line — green for bullish momentum, red for bearish — along with directional arrows at color-change transition points. The EA can use the arrows at crossovers or the current oscillator color and level to generate entries, depending on which of the six strategies you select. Installing the indicator on the chart alongside the EA lets you visually track entry logic in real time and verify the EA behaves exactly as expected for your chosen strategy and oscillator parameters.
Dark Mimas is completely free. There is no purchase price, no monthly subscription, no trial period limitation, and no license server that locks usage to a specific account count. Download the EX4 or EX5 file directly from darkeas.com/free-eas or the MQL5 marketplace at no charge. The developer also offers paid EAs in the Dark EAs product lineup — including Dark Nova, Dark Titan, and Dark Gold — but Dark Mimas is explicitly positioned as a free release. This makes it an accessible entry point for traders evaluating the developer's approach before committing to a paid product.
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.
