Stellar EA — XAUUSD H1 Breakout Robot with Built-In Drawdown Circuit Breaker

Stellar EA v3.5_fix is an automated XAUUSD expert advisor for MT4 that trades Gold on the H1 timeframe using candle body size filters and pending order entries to capture directional breakouts.

Across three backtests on $200–$2,000 starting capital, profit factor holds at 1.64–1.80 with peak drawdown between 8.86% and 25.96% over a 16-month test window.

Key Benefits

• ✅ Drawdown Circuit Breaker: Use_Max_DD halts and removes the EA at 50% account drawdown — hard stop most XAUUSD robots lack — though the 50% threshold still permits significant loss before activation.
• ✅ Breakout Strategy: Targets XAUUSD candle body momentum between 10–310 pips to filter noise — effective in trending Gold sessions, underperforms in tight range-bound price action. Compare EA strategies
• ✅ Daily Profit Lock: Per_Day_Take_Profit closes all activity after $500 daily gain — prevents over-trading in volatile Gold sessions, but caps upside on strong trend days.
• ✅ Fixed Lot Sizing: No Martingale or exponential scaling — lot size stays constant regardless of losing streaks, keeping drawdown predictable across all three tested capital levels.

Stellar EA Performance

Three backtests on $200, $590, and $1,000–$2,000 starting capital cover March 2024 – June 2025 on XAUUSD H1, all run on ICMarketssc-Demo04.

Performance Snapshot

Peak drawdown varies significantly by lot size relative to capital — the $1,000 test at 0.2 lots reached 25.96%, while the $2,000 test at an equivalent scaled lot hit 8.87%. Lot size selection is the primary lever controlling drawdown exposure, not a setting that adjusts automatically.

The drawdown mechanism is structural to position sizing: oversized lots relative to account balance amplify every losing streak. With maximum consecutive losses documented at 5 trades across all tests, an undersized account running 0.2 lots absorbs proportionally larger equity swings.

Sizing lots to keep drawdown below 15% — consistent with the $200 and $2,000 configurations — is the documented mitigation. No post-mitigation return range can be stated without knowing the buyer’s specific capital and intended lot size; run a demo with your target capital before going live.

These figures come from backtests run March–June 2025 on a demo build — live spread, slippage, and execution delays are not reflected in any result above.

How Stellar EA Works

Mechanism: Stellar EA trades XAUUSD on H1 by placing pending orders when a candle body falls within a defined size range (Min_Body_Pips 10 – Max_Body_Pips 20–310 depending on configuration). It targets directional momentum moves in Gold — sessions where price commits to a clear range break rather than choppy back-and-forth. The H1 filter means it skips micro-noise while still catching intraday Gold swings driven by macro catalysts and session opens.

Signal Trigger: A pending entry fires when the prior candle body size falls between the configured minimum and maximum pip thresholds, and price is at least Entry_Gap_Pips (20) away from the pending order level. ATR period 60 is used for dynamic context though dynamic SL is disabled in documented configurations.

Position Close: Each trade carries a fixed take profit at 100 static points with Use_TP_RR enabled. The EA closes all daily activity once the Per_Day_Take_Profit value of $500 is reached. No trailing stop is active in the tested configurations (is_trailing: false).

Exposure Limits: Use_Max_DD caps total drawdown at 50% of account equity — when breached, Remove_EA_On_DD terminates all trading and detaches the EA. Fixed lot sizing prevents any position from scaling up after a loss. No Martingale, no averaging down.

✅ Optimal conditions: Trending Gold sessions with clear directional momentum — London open, New York open, or macro-driven moves where XAUUSD establishes a clean breakout candle on H1.

⚠️ Avoid when: XAUUSD is ranging tightly (body sizes consistently below 10 pips) — the pending orders either don’t trigger or trigger at range extremes before reversal. Also avoid during scheduled high-impact USD news events if no external news filter is applied, as spike candles can breach SL before momentum follows through.

Recommended Settings

Who Should Use Stellar EA

• ✅ Running MT4 on a VPS with uninterrupted connectivity — pending order strategies fail when the terminal disconnects mid-session
• ✅ Funding $1,000 or more — the $1,000 test at 0.2 lots reached 25.96% drawdown; $2,000 with equivalent scaling kept it under 9%
• ✅ Trading XAUUSD exclusively — the body-size filter and ATR logic are calibrated for Gold volatility, not currency pairs
• ✅ Comfortable sizing lots conservatively — buyers who want to run maximum lot sizes relative to capital will see the worst-case drawdown scenario, not the best-case one

Performance verified with: ICMarketssc-Demo04 ECN demo environment, 0.1–0.2 lot sizing, $200–$2,000 starting capital across four separate backtest runs.
