Marvin EA MT4 – Grid Recovery EA for XAUUSD & EURUSD with 766% Live Account Growth

Marvin EA v2.0 is an MT4 Expert Advisor built on the Marvin Non-Repaint signal engine combined with ATR-based grid spacing — a hybrid signal-plus-grid approach. The live account (FBS Real-3, owner: Patricia Cristina Lippa) reports 766% cumulative ROI from an $856 initial deposit, with a 23.6% peak drawdown. These are vendor-reported figures from a CopyFX signal; independent third-party verification via MyFxBook is not available, and results should be treated as unverified pending your own demo validation.

Key Benefits

• ✅ Live Growth Record: Vendor-reported 766% ROI from $856 initial deposit on FBS Real-3 — 68.2% win rate across active trading weeks since 2022.
• ✅ Preliminary Backtest Edge: EURUSD H1 backtest (Oct–Dec 2023) shows profit factor 2.46 and 9.08% max drawdown — limited 3-month window reduces predictive reliability.
• ✅ Built-In Exposure Controls: DrawdownMax 35% equity stop + ATR-scaled order spacing (OrdensPortATR 15) + max spread filter (40 points) cap worst-case exposure automatically.
• ✅ No DLL — MT4 Native: Runs without external DLL dependencies; compatible with standard MT4 builds 1415+; includes preset setfiles for immediate deployment.
• ✅ Dual-Market Automation: Configured for XAUUSD and EURUSD on M15; runs 24/5 without manual intervention on a VPS.

Marvin EA Performance

The vendor-reported live account (MARVIN 20, FBS Real-3) logs 766% cumulative return from a $856 starting balance, reaching $7,203.76 with zero withdrawals. Yearly trajectory: 240.39% in 2022 → 117.94% in 2023 → 16.80% in 2024 YTD — a significant and visible deceleration that buyers should factor into forward expectations. The 97% algotrading ratio and 89/100 reliability score are CopyFX platform metrics, not independently audited figures.

The EURUSD H1 backtest (Oct–Dec 2023, $1,000 initial deposit) indicates a profit factor of 2.46, 72.24% win rate across 281 trades, and 9.08% max drawdown — modeled on open prices only, which excludes intra-bar slippage and spread impact.

Risk disclosure: The 23.6% peak drawdown occurs under grid accumulation — when the EA stacks positions across ATR-spaced levels during trending markets that don’t reverse. The DrawdownMax: 35% parameter triggers a full position halt before account equity reaches critical levels. With conservative settings (Lota: 0.01, LotExponent: 1.4, OrdensPortATR: 15), the backtest recorded 9.08% max drawdown. Live drawdown reached 23.6%, indicating real-market conditions produce materially higher exposure than open-price backtest figures suggest.

Performance claims sourced from vendor-provided CopyFX data, not independently verified by cheapforexea. Backtest used open-price modeling — excludes real-time slippage and spread widening. Minimum 90 days demo testing required before live capital deployment.

How It Works

Entry Signal: Opens buy or sell when the Marvin Non-Repaint indicator fires — direction controlled by lib_compra / lib_venda parameters (configurable per chart window).

Grid Spacing: Subsequent orders placed at intervals calculated as ATR(30) ÷ OrdensPortATR(15), with a minimum floor of MinimumFlips(150) points — spacing auto-adjusts to current volatility.

Lot Scaling: Base lot 0.01; each additional grid position multiplied by LotExponent(1.4) — exposure compounds as the grid extends deeper.

Take Profit: TakeProfit set at 75 points; MultiplicadorTakeProfit(2.0) can extend target on final position. Grid closes on collective profit target, not individual trade TP.

Drawdown Stop: DrawdownNormal(10%) triggers soft caution; DrawdownMax(35%) halts all new orders globally — acts as the primary account protection mechanism.

Spread Filter: spread_máximo(40 points) blocks new entries when spread exceeds threshold — critical for XAUUSD during volatile sessions.

Optimal conditions: Ranging or mean-reverting markets; ECN broker with XAUUSD spread under 30 points; $1,000+ capital; 1:500 leverage; VPS with stable connection.

Avoid when: Strong unidirectional trends on gold; high-impact news events; accounts under $500 with aggressive lot settings; brokers with variable spread spikes above 40 points.

Why Choose & Use This EA

• ✅ You hold $1,000+ capital — grid accumulation at $500 minimum leaves thin margin buffer during extended drawdown sequences.
• ✅ Your broker offers 1:500 leverage with ECN execution and XAUUSD spread consistently under 30 points.
• ✅ You accept a grid/scaling risk model — LotExponent 1.4 compounds position size; strong trends can push drawdown toward the 23.6% live peak before DrawdownMax halts trading.
• ✅ You run a VPS 24/5 — signal-triggered entries require continuous MT4 connection; disconnection during open grid = unmanaged exposure.
• ✅ You complete 90+ days demo testing before live deployment — developer-claimed results only; independent verification not available.
