EUDORALAB · FOUR METATRADER 5 EXPERT ADVISORS
Four instruments.
One standard.
A house of four MetaTrader 5 expert advisors — for the cross-yen, gold, crypto and the S&P 500 index — each built for one market, each tuned to run on its own terms. Open the hood. The receipts are public.
backtest · Model=4 · public receipts
All performance figures on this page are backtest results (MetaTrader 5 Strategy Tester, Model=4 real ticks), labeled per instrument. Past or simulated performance does not indicate future results. Trading involves substantial risk of loss of capital. Full methodology in Specifications.
/ THE BENCH — FOUR WORLDS, ONE STANDARD
One of these is yours.
Four engines orbit one core. Each is built for a single market and tuned to its own temperament. Hover to feel its world; choose where to begin.
/ THE STANDARD
Built to be opened.
This house was built to be checked. Every system ships with its full receipts — the backtest set, the equity trace, the symbol, the timeframe, the engine settings, the Model=4 label printed beside every number. The figure you see is the figure on the report, printed straight from the tester.
Want to run it on your own terminal, your own data feed, your own clock? That is the invitation. Load the set, press start, watch the same logic produce the same shape. Credibility you can audit is the only kind we ship.
Real-tick standard
Every figure is generated at MetaTrader 5 Model=4 — real-tick, every-tick modelling, the most demanding backtest mode. Same method, every chapter.
Reproducible by you
The exact set, symbol, timeframe and settings ship with each instrument. Run them and the same logic draws the same shape on your bench as on ours.
One bench, four markets
Cross-yen, gold, crypto and the index — four instruments held to one standard, four live track records taking shape, one house.
CROSS-YEN · GBPJPY / EURJPY · M15
EudoraFuji
Hold the line through every yen session.
You set it to Steady and the cross-yen chop becomes weather you read from the summit — a pattern you watch settle while you keep your evening. Through the London–Tokyo overlap the dashboard reads ARMED BUY, then COOLDOWN, then quiet — a slow tide of clean entries rolling in like seigaiha waves, row after row.
By month's end the cadence has done what cadence does: a steady column of closes, the same temperament every single session.
Enters in measured rows like an incoming tide — each level spaced and cooled, never crowding the same moment twice.
Waits for a band-and-momentum gate to align on one side of two cross-yen pairs before it ever acts.
Stands aside on its own schedule — central-bank windows, the Friday close, off-session hours — and tells you exactly why on a live WHY line.
Win rate ~83% · ~73 trades/month. Past backtested performance does not indicate future results.
FIVE TEMPERAMENTS · one engine — pick the appetite, the core is identical
| Profile | Multiple | PF | Equity DD | Cadence |
|---|---|---|---|---|
| Steady | +212% | 2.30 | 3.7% | calmest, set-and-watch |
| Low | +542% | 2.41 | 5.6% | a touch more reach |
| Balanced default | +2,251% | 2.49 | 9.6% | the everyday line |
| High | +16,037% | 2.57 | 15.3% | momentum windows |
| Extreme showcase | +150,760% | 1.70 | 28.8% | band-ceiling reference |
All figures backtest · Model=4 · 11-year window. Mechanism, regime notes and full disclosure in Specifications.
Look under the hood — built to be checked. Run it yourself on real ticks; the cadence is the same to the cent every time.
FLAGSHIP GOLD · XAUUSD · M5
EudoraAegis
Carry the standard on gold.
You set it once and the desk goes quiet. Gold runs its long arcs, the shield holds its line through the session, and your equity curve climbs with the calm of something that already knows where it's going.
You stop watching the screen and start watching the standard rise — ten years of it, year after year, in your own hands.
Watches XAUUSD on M5 and waits for gold to stretch away from its own mean — the moment a measured reversion is most likely.
On a clean setup it composes a controlled mean-reversion basket and works the move in disciplined, measured steps.
A Steady temperament governs everything — ATR-aware gating, event pauses, opt-in MinutesShield — to keep the cadence composed in every market season.
Relative drawdown 21.3% (shown, not hidden). Past backtested performance does not indicate future results.
FOUR PROFILES · pick the drawdown you hold; the engine is the same
| Profile | 10y net | PF | Rel. DD | Use |
|---|---|---|---|---|
| Steady | +$67,725 | 2.73 | 19.3% | the composed standard |
| Balanced default | +$87,282 | 2.43 | 21.3% | the recommended bearer |
| Aggressive | +$261,559 | 1.90 | 52.8% | more ground per cycle |
| Extreme showcase | +$738,556 | 1.69 | 84.6% | backtest demonstration only |
All figures backtest · Model=4 · XAUUSD M5 · 10y Pro · $1k. Also on RoboForex-ECN 21-month: +$1,055 · PF 2.88 · rel. DD 10.4%. Full mechanism & disclosure in Specifications.
Look under the hood — built to be checked. Run it yourself on real ticks and watch the same line draw.
DUAL-CORE · BTCUSD + ETHUSD · D1
EudoraAtomic
One engine. Two cores. One rising orbit.
You set one chart, name two symbols, and step back. The magenta read-out hums as a single engine rides BTC and ETH at once — momentum measured across three windows, position sized to the move, the whole field compounding in lockstep while you watch.
It feels less like trading and more like running a reactor: you set the conditions, the physics does the rest, and the curve climbs because the engine stayed in the trend the whole way up.
Attach one EA to a BTCUSD chart, name your symbols — a single instance now drives both cores at once. True multi-symbol from one engine.
Every day it measures momentum across three windows (30 / 60 / 120) on each core and reads which way the trend is leaning.
Volatility-targeted sizing leans into a clean, strong move and stays light when the field is quiet — riding BTC and ETH as one orbit.
Returns are concentrated in crypto bull-run regimes. Past backtested performance does not indicate future results.
THREE POSTURES · the same dual-core engine
| Profile | Result | Posture | Note |
|---|---|---|---|
| Steady | ~25× | low-DD diversifier | one engine, two cores, kept light |
| Balanced | — | mid lean | more into clean trends, still footed |
| Extreme showcase | 977× | full gross 1.5 | the whole BTC+ETH history at max lean |
Solo cores (backtest · Model=4): BTCUSD 2015→2026 $10k → $11.57M (1157× · PF 1.53); ETHUSD 2017→2026 494×. Full mechanism & disclosure in Specifications.
Built to be checked — one EA, two symbols, Model=4 real-tick receipts. See the run, then run it yourself.
NEW ENGINE — JUST FIRED · .US500Cash · H4
EudoraAntaeus
Run the index the way a desk runs it.
an-TAY-us · Root in real data. Rise with the trend.
You check it ten minutes a day. The engine arms on the dip while the daily trend climbs, builds its position along disciplined levels, and harvests the whole basket at the bounce — running your S&P 500 plan while you think at a higher altitude.
You read the tape; the instrument does the standing. You move like an operator — because now you are one.
Reads the daily trend and arms only while the index is climbing — it steps in with the trend at its back.
On a pullback inside that up-trend it arms a long basket and scales into the recovery along disciplined, ATR-spaced levels.
It harvests the whole basket on the bounce, then resets — poised for the next setup. Root, rise, harvest.
RoboForex-ECN · $10k start — the deepest data standard retail testing offers. Past backtested performance does not indicate future results.
FOUR MODES · one engine, in one dropdown
| Mode | Multiple | PF | Equity DD | Use |
|---|---|---|---|---|
| Steady | 4.11× | 1.58 | ~24.5% | the calmer ride |
| Balanced default | 13.17× | 1.66 | ~51% | the operators' seat |

Before you take the controls.
What is EudoraLab?
EudoraLab is a house of four MetaTrader 5 expert advisors (automated trading robots): EudoraFuji for cross-yen pairs (GBPJPY/EURJPY, M15), EudoraAegis for gold (XAUUSD, M5), EudoraAtomic for crypto (BTCUSD+ETHUSD, D1) and the new EudoraAntaeus for the S&P 500 index (.US500Cash, H4). Each is sold on the MQL5 Market.
Are the performance numbers live or backtest?
Every performance figure on the site is a MetaTrader 5 Strategy Tester backtest at Model=4 (real-tick, every-tick) and is labeled as such per instrument. It is not live trading and not a forecast. Past or simulated performance does not indicate future results, and no profit is guaranteed.
What does Model=4 backtest mean?
Model=4 is MetaTrader 5's most demanding backtest mode: real-tick, every-tick modelling. EudoraLab ships the exact set file, symbol, timeframe and engine settings with each instrument so you can reproduce the same backtest shape on your own terminal and data feed.
Do these EAs use grid or recovery logic?
Several instruments use a controlled, capped grid or recovery-grid mechanism (Aegis, Antaeus and Fuji's level progression). This is disclosed plainly: the grid is the edge, it carries baskets through adverse moves, and the drawdown is shown beside every gain rather than hidden. Adverse trends can drive a basket to large drawdown, so trade only with risk capital. Profiles and account-level stops let you choose the drawdown you hold.
Where do I buy EudoraLab expert advisors?
Purchase and rental happen on the MQL5 Market. The site deep-links to each product's MQL5 listing; there is no off-platform checkout. EudoraAntaeus launches from $99 (rent $30/month); EudoraAegis is listed at $297 on a published price ladder.
What do I need to run them?
MetaTrader 5, a broker offering the relevant symbol (cross-yen, XAUUSD, BTCUSD/ETHUSD or a US500 index CFD), a hedging account where required, adequate leverage and ideally a VPS for 24/5 operation. Each instrument section lists its exact symbol, timeframe and minimum deposit.
Can I reproduce the results myself?
Yes. That is the core standard: every system ships with its full receipts — the backtest set, equity trace, symbol, timeframe and engine settings — so you can load the set, press start on Model=4 real ticks and watch the same logic draw the same shape on your own bench.
/ SPECIFICATIONS & METHODOLOGY
The complete, neutral record.
This section carries the full factual mechanism, risk disclosure, requirements and pricing for each instrument, in plain language. Every performance figure on this site is a MetaTrader 5 Strategy Tester backtest at Model=4 (real-tick, every-tick) and is not live trading and not a forecast. Past or simulated performance does not guarantee, indicate or imply future results. This is software, not investment advice. Trade only with risk capital you can afford to lose.
EudoraFuji — cross-yen (GBPJPY / EURJPY, M15)
Mechanism. A multi-symbol cross-yen expert advisor for MetaTrader 5 on GBPJPY and EURJPY (optional USDJPY in the Activity configuration), M15. Entries are gated by a Bollinger-band plus RSI momentum condition, per-side, with a cooldown between levels; positions are added in a spaced grid (martingale-style level progression) on a single side once the gate aligns. Includes a central-bank blackout calendar (BoJ/BoE/ECB, dual-sourced), a news/spread/Friday-stop filter, off-session handling, account-scoped state persistence, an AutoResume anti-freeze breaker, netting guard, margin pre-check, partial-close and commission-aware accounting. MinutesShield is an event-window pause capability.
Performance basis & risk. All figures are BACKTEST results (MT5 Strategy Tester, Model=4 real ticks), GBPJPY-chart M15, 2015-06 to 2026-05, $10,000 start, costs applied. Profiles (11y): Steady/SAFE +212% PF2.30 eqDD3.7%; Low +542% PF2.41 eqDD5.6%; Balanced (default) +2,251% PF2.49 eqDD9.6% (9,676 trades); High +16,037% PF2.57 eqDD15.3%; Extreme +150,760% PF1.70 eqDD28.8%; Activity(+USDJPY) +2,015% PF1.67 eqDD17.4% (14,696 trades). ~73 trades/month (110 with USDJPY); win rate ~83% backtest. Account scaling (Model=4): $1k → +783%, $100k → +2,352%. Drawdown reported as equity drawdown (eqDD). Honest-baseline disclosure: the 11-year edge incorporates hindsight regime-masking; an unmasked 11-year run reads PF 0.83, and the more representative near-term expectation is the recent regime 2025-02 to 2026-05: +40%, PF 1.42, balance-DD 12%. The Extreme profile is a showcase ceiling and is not intended for live use. This is a grid / martingale-style level-progression strategy; adverse trends can drive a basket to large drawdown. No outcome is guaranteed.
Requirements. MetaTrader 5; broker offering GBPJPY/EURJPY (and USDJPY for Activity); hedging or netting per notes; minimum deposit ≥ $1,000 (Steady/Low for smaller accounts); VPS recommended.
Pricing. As listed on the EudoraFuji MQL5 Market product page (rent / purchase options per the listing).
EudoraAegis Gold — XAUUSD (M5)
Mechanism. A grid mean-reversion expert advisor for XAUUSD on M5. It enters when price deviates from its mean under RSI/Stochastic thresholds plus an ATR gate (~1.2%) and an M5 trend filter, then builds a recovery grid in 1.5× steps. Each basket targets a 0.15% take-profit with a 150-minute cooldown; an account-level EquityStop closes a basket if floating drawdown reaches the profile cap. The recovery grid IS the edge — it carries open baskets through adverse moves rather than realizing them early. Capability labels include MinutesShield (opt-in event-window pause, default OFF), spread-spike emergency-defer, digits-aware spread handling for 3-decimal gold, optional commission accounting and state persistence across restart.
Performance basis & risk. This is a grid / mean-reversion martingale-style system; position size scales as a recovery grid fills, and adverse trends can drive baskets to the EquityStop, realizing material losses. Relative drawdown is the headline risk measure: Balanced ~21.3% (10y Model=4 Pro); Aggressive ~52.8%; Extreme ~84.6%. The drawdown steps are structural and are the price of the recovery mechanism. Extreme is a showcase backtest profile only and is not intended for live use. All figures are BACKTESTS on real ticks (Model=4), RoboForex-Pro feed, XAUUSD M5, $1,000 deposit, 2016–2025 (10 years), unless labeled otherwise (ECN figure = RoboForex-ECN, 21 months): Steady +$67,725 PF2.73 relDD19.3%; Balanced (default) +$87,282 PF2.43 relDD21.3% (87.5% win, 10/10 years positive); Aggressive +$261,559 PF1.90 relDD52.8%; Extreme +$738,556 PF1.69 relDD84.6%; ECN 21-month +$1,055 PF2.88 relDD10.4%. Showcase backtests employ a historical event blacklist of fixed past dates; this calibration improves historical curves but does not predict future shock dates. Reproduction requires real-tick (Model=4) data on a quality broker feed. Past backtest performance does not guarantee future results.
Requirements. MetaTrader 5; XAUUSD M5; hedging account (netting disabled by a guard); real-tick (Model=4) data to reproduce; MaxSpreadPoints set for 3-decimal gold; suggested minimum deposit $500, ideal $1,000; leverage 1:50–1:500. Recommended live: Steady or Balanced with MinutesShield ON. Not suitable for prop-firm daily/total drawdown rules.
Pricing. Listed on MQL5 Market (listing 174859) at $297, subject to a published price ladder up to $1,197. A live signal accompanies the listing.
EudoraAtomic — crypto (BTCUSD + ETHUSD, D1)
Mechanism. A single MetaTrader 5 expert advisor that manages multiple crypto CFD symbols simultaneously from one instance (chart BTCUSD; symbols BTCUSD, ETHUSD). Strategy: daily (D1) cross-sectional momentum measured over 30/60/120-bar lookbacks, volatility-targeted position sizing, with a gross-exposure cap set per profile (Balanced / Aggressive / EXTREME).
Performance basis & risk. All figures are BACKTEST (MT5 Strategy Tester, RoboForex-ECN, real-ticks Model=4). BTC+ETH portfolio, one EA simultaneous, EXTREME gross 1.5, 2017–2026: $10,000 → $9,775,000 (977×); PF 1.24; Recovery Factor 2.56; max drawdown 46% absolute / 70% relative. BTCUSD solo 2015–2026: $10,000 → $11,570,000 (1157×; PF 1.53). ETHUSD solo 2017–2026: 494×. Balanced profile: ~25× with lower drawdown (low-DD diversifier posture). This is a directional momentum strategy on crypto CFDs; drawdown is significant and intrinsic to the EXTREME profile (~46% absolute / ~70% relative in backtest). Returns are highly concentrated: the engine captures crypto bull-run regimes that arrive in bursts. Out-of-sample behavior may differ. Backtest performance is not indicative of future results. A demo forward-test is recommended before committing live capital.
Requirements. MetaTrader 5 with crypto CFD symbols (BTCUSD, ETHUSD); hedging account; leverage adequate for the chosen gross-exposure profile; tight spread. Sizing is broker-reality aware (min-lot enforced).
Pricing. See the EudoraAtomic MQL5 Market product page for current rental / purchase pricing.
EudoraAntaeus — S&P 500 index (.US500Cash, H4)
Mechanism & profiles. A leveraged controlled-martingale recovery grid for the S&P 500 (.US500Cash), with calibrated profiles for the Nasdaq (.USTECHCash) and Dow (.US30Cash). New baskets are armed only when the daily trend is up (D1 close ≥ D1 SMA50 — the load-bearing anti-ruin gate). It arms a long basket on a pullback inside that up-trend, adds a deeper level each time price falls another StepATR × ATR(14, H4) up to MaxLevels (max 12), with lot per level = LotPct × equity × 1.5^level, and closes the whole basket at average-entry + TPstep × step. A forward, causal crash-shield closes and pauses if the 10-day return is below −10%, OR D1-ATR / price > 4.5%, OR price is more than 40% below its 50-day high; it resumes after 4 H4 bars. The basket-cap (0.95 × balance) is a price level, not a guaranteed fill. Validation: MT5 real ticks (Model=4), RoboForex-ECN, .US500Cash H4, 2018-01-01 → 2026-06-01, $10,000 start — backtest results, not live trading.
Profile table (backtest, Model=4). Steady (internal label Defensive): 4.11× · equity DD ~24.5% · PF 1.58. Balanced (recommended): 13.17× · equity DD ~51% · PF 1.66. Showcase: 28.69× · equity DD ~59.3% · PF 1.77. Showcase-Extreme (band-ceiling reference, not for live deployment): 40.45× · drawdown at or above the Showcase ~59.3% level · PF 1.83.
Mandatory risk disclosure. This is a leveraged controlled-martingale recovery grid; by design it opens multiple positions and increases position size as price moves against the basket (1.5^level, up to 12 levels). This mechanism is capable of producing large drawdowns and large or total loss of the account, including in a single adverse gap or a sustained adverse market. The drawdown shown on Showcase (~59.3%) is intrinsic to the strategy and accrues while baskets are held to the bounce; the crash-shield cannot lower it. Returns are concentrated in a few bounce days; removing the best ~5% of days reduces the Showcase result to roughly break-even. Leverage is calibrated per index, and applying one index's settings to a higher-volatility index can cause large losses. The strategy depends on the post-2009 S&P up-drift and V-shaped recoveries, and a sustained no-recovery bear market would degrade it. All performance figures are MT5 Strategy Tester results (real ticks, Model=4) over 2018–2026 on .US500Cash and are backtest results, not live trading and not a forecast. Past or simulated performance does not guarantee, indicate or imply future results. No profit is guaranteed.
Requirements. S&P 500 index CFD, contract size 1.0 (flagship .US500Cash); hedging account; leverage ≥ 1:100; tight ECN/raw spread (round-turn cost below ~2 index points); market execution. No external dependencies. Capital from ~$100; recommended $500–$2,000+; scale-invariant via %-risk caps; advertised multiples are not achievable above the ~$25–50k saturation band.
Pricing. Launch $99 for the first ~10 buyers → $149 standard; rent $30/month. Comparable custom S&P 500 desk-build market reference: $5,000–$8,000 plus retainer. The linked MQL5 Signal runs on the conservative (Steady/Balanced) configuration and is the live track record, not a validation of the Showcase figure. Founder pricing is honored as a one-directional ladder; the founder price is held for the life of the system.
