i5 MEGA EA — XAUUSD H1 Grid Strategy on MT4

i5 MEGA EA is a MetaTrader 4 grid-based expert advisor that trades Gold (XAUUSD) on the H1 timeframe, opening layered positions as price moves against the initial entry and closing baskets at a cumulative take profit level.

A 50-day backtest on $1,000 capital shows 98.84% win rate across 1,206 trades at 23.21% peak drawdown.

Key Benefits

• ✅ Win Rate: 98.84% across 1,206 backtest trades — achieved through grid averaging that delays closes until the basket is profitable, meaning single losing trades carry outsized loss potential.
• ✅ Strategy: Exploits mean-reverting price behavior on XAUUSD H1 by opening additional positions at fixed pip intervals — effective in ranging conditions, exposed in sustained directional trends.
• ✅ Risk Controls: MaxSpread filter (80 points), configurable trading hours (09:00–23:00), and percentage-based lot sizing limit uncontrolled execution — drawdown circuit breaker is available but disabled by default.
• ✅ Lot Scaling: Lot size scales automatically with balance (0.01 per $2,350) — keeps exposure proportional as account grows, but accelerates loss if grid compounds during a trend.

A second backtest run (September 1 – October 15, 2025) on $200 initial deposit produced 1,092 trades, 98.90% win rate, and 27.73% peak drawdown — consistent win rate across both capital levels confirms the percentage-based lot scaling behaves as designed.

The specific trigger for elevated drawdown is a sustained directional move on XAUUSD — when price trends consistently in one direction without reversion, the grid adds positions at each PipStep interval (25 pips default) and the open basket grows until a correlated loss materializes. This is a structural characteristic of any grid strategy: it cannot be removed, only sized for.

Relative drawdown reaches 39.85% in the backtest, meaning account equity dropped to 60% of peak balance at the worst point — relevant for anyone setting equity-based stop thresholds.

The CloseTradesAtPercentageDrawdown and CloseTradesAtFixedDrawdown controls are available in settings but disabled by default; enabling either with a defined threshold converts this from a structural risk to a partially controllable one — post-mitigation return impact is not documented and requires live or demo testing to classify.

Both reports use the Control Points modeling method — the lowest-quality backtest mode in MT4. This method does not simulate tick-by-tick execution and cannot account for spread spikes, slippage, or partial fills that live XAUUSD trading introduces.

How i5 MEGA EA Works

Mechanism: Trades XAUUSD mean reversion on H1 by opening an initial position and adding grid layers at every 25-pip adverse move (PipStep: 25). The basket closes collectively when cumulative take profit is reached, producing a high win rate in ranging conditions. In a directional trend without reversion, each layer adds to an open floating loss.

Signal Trigger: Positions open within the defined session window (TimeStart: 02:00 – TimeEnd: 23:00), filtered by spread (MaxSpread: 80 points). The EA does not require an external indicator signal to open — entry is position-spacing based, not pattern-based.

Position Close: Individual trades carry a 20-pip take profit (TakeProfit: 20) with a trailing stop activating at 8 pips in profit (TrailStart: 8) and trailing by 10 pips (Trail: 10). The basket closes collectively when aggregate profit threshold is reached.

Exposure Limits: Lot size scales at 0.01 per $2,350 balance (UseLotForEveryBalance: 2350, UseLotForEveryBalance lot: 0.01), capping over-exposure as account grows. MaxSpread filter prevents execution during wide-spread conditions. Drawdown circuit breakers (CloseTradesAtPercentageDrawdown, CloseTradesAtFixedDrawdown) are available but require manual activation.

✅ Optimal conditions: Ranging XAUUSD price action with regular reversion to mean; active Asian and European session overlap; stable spreads below 8 pips.

⚠️ Avoid when: Strong directional USD news events (CPI, NFP, FOMC) drive sustained XAUUSD trends; spread widens above 80 points for extended periods.

Who Should Use i5 MEGA EA

Purchase this EA if you:

• ✅ Run MT4 on a VPS with continuous uptime — grid positions require uninterrupted connection to manage open baskets
• ✅ Have $1,000 or more available capital — the $200 minimum is functional, but 39.85% relative drawdown at low capital leaves no margin buffer during a trend
• ✅ Trade XAUUSD exclusively and understand that grid averaging concentrates all risk on one instrument and one market condition
• ✅ Will enable and configure the drawdown circuit breaker settings before going live — running default settings means no automatic basket close on deep drawdown
