Nexa Aurum EA V1.0 MT5 — Adaptive Grid for XAUUSD

Platform: MetaTrader 5 (MT5)
Pair: XAU/USD (Gold only)
Account Size: From $500 (recommended $1,000+)
Broker: ECN/RAW spread, fast execution (1:300–1:500 leverage)
Execution: VPS strongly recommended for stability

The Nexa Aurum EA V1.0 is a gold-exclusive Expert Advisor that blends grid mechanics with modern adaptive risk controls. Unlike fixed-step grid systems that collapse in strong trends, Nexa Aurum dynamically sizes grid steps using ATR-based logic with min/max clamps, ensuring the grid breathes with market volatility. Built-in equity and margin protection, daily loss guards, and strict layer limits make it safer for long-term deployment compared to reckless, open-ended grids.

Key Features

Adaptive Grid Step (ATR-based)
Grid spacing adjusts automatically to volatility.

Min clamp: prevents overly tight spacing in calm sessions.

Max clamp: ensures spacing doesn’t widen excessively during high volatility.

Historical News Filter (Backtest Mode)
Unique ability to test with vs. without news filter from 2020 onward.
Useful for evaluating how gold reacts to CPI, NFP, FOMC events.

Day & Session Filters

Monday Rules: Option to skip or delay trading until liquidity normalizes.

Friday Rules: Flatten positions before weekend gaps.

Trading Hours Window: Define precise active session windows (e.g., London–NY overlap).

Trading Modes (Optional)
Choose between conservative, balanced, or aggressive templates.

Account Protection

Equity Stop: Shut down trading when equity drawdown hits threshold.

Margin Guard: Auto close trades when margin usage is unsafe.

Daily Loss Guard: Halts new trades for the day after hitting defined loss.

Max Layers: Hard cap on number of grid levels to prevent runaway exposure.

Recommended Setup

Broker: ECN/RAW spread with fast execution (tight spreads crucial on XAUUSD).

Leverage: 1:300–1:500 for breathing room.

Account Size: Minimum $500 (micro lots possible), recommended $1,000+.

VPS: Dedicated low-latency MT5 VPS required.

Symbol: XAU/USD only (this build is gold-exclusive).

Timeframes: Works on any chart TF (logic is tick-driven).

Example Workflow

ATR-based grid spacing is calculated at start.

EA checks Monday/Friday filters and session timing.

If conditions are met, grid engine begins layering BUY/SELL trades.

Max layers + equity guard ensure the grid doesn’t spiral.

News filter blocks new entries near high-impact events.

Positions are closed via basket take-profit, daily guard, or protective equity stop.

Pros & Cons

Pros

Gold-specific tuning (XAUUSD only).

ATR-based step adjustment avoids rigid spacing failures.

Full suite of protections: equity, margin, daily loss, layer caps.

Historical news filter for realistic backtests.

Monday/Friday & session controls.

Cons

Still a grid system (drawdowns inevitable if misconfigured).

Not multi-symbol; limited to gold.

Requires VPS + strong broker execution.

Higher learning curve compared to “plug-and-play” bots.

FAQ

Does it use martingale?
No. While it layers trades, lot sizing can remain fixed or progressive, but no uncontrolled martingale.

Can I trade other pairs?
No. This build is gold-only (XAU/USD).

Is it prop firm compatible?
Partially. Depends on firm rules — many disallow grids due to potential DD. Use conservative templates if attempting.

How many layers should I use?
Start with 3–5 max layers; never allow unlimited stacking.

What about weekend safety?
Friday rules can be enabled to flatten trades before close.

Final Thoughts

Nexa Aurum EA V1.0 MT5 is a carefully engineered adaptive grid system for gold. By combining ATR-driven spacing, built-in equity/margin guards, news-aware backtesting, and strict session filters, it’s far safer than traditional “set and forget” grid bots. Still, it remains a grid strategy — use VPS, strong brokers, and conservative settings. Best suited for traders who understand gold’s volatility and want a controlled, disciplined grid approach.
