Harmonacci Pattern EA — Review & Parameter Guide
Overview
Harmonacci Pattern EA is a rule-based Expert Advisor for MetaTrader 5 that automates harmonic (XABCD) price pattern trading. It scans price swings using a faithful port of MetaQuotes’ own ZigZag indicator, matches the swing points against 19 harmonic pattern templates (Fibonacci ratio tables), constructs a Potential Reversal Zone (PRZ) for each candidate, and only opens a trade after price breaks out of that zone in the expected direction — not on the first touch.
An optional AI confirmation layer (powered by Grok / xAI) can be enabled to let a large language model review recent candles before every entry. However, the EA is fully self-contained and works perfectly with this feature disabled.
This article explains what the EA does well, its real limitations, and provides a detailed guide to every input parameter so you can configure it correctly for your account and instruments.
Strengths
- No external indicator dependency: The ZigZag calculation is embedded directly in the EA (ported line-for-line from the official MetaQuotes ZigZag.mq5). No iCustom() calls, no missing indicator errors, and no extra files to install.
- Broad pattern coverage: Supports 19 harmonic templates (Gartley, Cypher, Barracuda, and 16 trademark-safe variants including Flying Fox, Lobster, Dragonfly, White/Black Swan, Max and A- extended families). Each pattern can be enabled or disabled independently.
- Confluence-based PRZ: The reversal zone for point D is built from two independent Fibonacci projections (BC→D extension and XA→D retracement) and is only accepted where they overlap. This significantly filters out low-quality matches.
- Breakout confirmation: The EA waits for a confirmed directional breakout after price enters the PRZ, avoiding entries at the first touch of a level that may not hold.
- Clear invalidation and timeout logic: A setup is cancelled the moment price closes beyond point X, or after a configurable number of bars without confirmation.
- Margin-aware position sizing: Lot size is calculated based on account risk percentage, then verified with real free margin using OrderCalcMargin. The EA automatically reduces size or skips the trade if margin is insufficient.
- Staged exits: Each signal can be split into three separate tickets with independent take-profit levels anchored to the pattern structure (point C, Fibonacci retracement of C–A, and point A).
- Optional AI second opinion: When enabled, the EA sends pattern structure and recent candles to an LLM and requires approval before entering. Disabled by default — no internet dependency for core operation.
- Excellent visual transparency: Real-time drawing of X-A-B-C labels, trend lines, PRZ rectangle, and ratio values on the chart.
Limitations & Honest Caveats
- Single active setup at a time: The EA tracks and manages only one candidate pattern simultaneously. It does not evaluate multiple overlapping patterns in parallel like a manual trader might.
- No trend or multi-timeframe filter: Purely price and ratio-based on a single timeframe. Counter-trend setups can and will be taken.
- Wide-tolerance patterns create noise: Templates with very broad ratios (especially White Swan and Sea Pony) generate frequent matches and invalidations. Disable them first if you see too many “Candidate invalidated” messages.
- ZigZag repaint behavior: Like any ZigZag system, the most recent swing can repaint. Patterns lock only after C is confirmed, but recent D projections can still shift slightly.
- No trailing stop or breakeven: SL/TP are fixed at entry. Trade management relies on the three staged take-profits.
- AI confirmation adds latency and cost: Requires internet and API billing. Not recommended for long-term backtesting.
- Backtest quality depends on broker data: Results vary significantly between “Every tick based on real ticks” and lower-quality modeling.
- Not a guaranteed profit system: Harmonic patterns are probabilistic. Thorough backtesting on your specific symbol, timeframe, and broker is essential.
Complete Parameter Reference
1. ZigZag / Swing Detection
These parameters define how the EA detects swing highs and lows, forming the foundation of XABCD pattern recognition.
- InpZZDepth (Default: 12): Number of bars to look on each side for a swing high/low. Higher values detect major swings, lower values catch minor swings and wicks (increases signal frequency but adds noise).
- InpZZDeviation (Default: 50): Minimum price movement in points required to confirm a new swing in the opposite direction.
- InpZZBackstep (Default: 3): Minimum number of bars between two consecutive opposite swings to reduce clutter.
- InpMaxHistoryBars (Default: 3000): Maximum historical bars used to reconstruct the ZigZag indicator.
2. Pattern Matching
- InpRatioTolerance (Default: 0.04): Tolerance added to standard Fibonacci ratios (e.g., 0.618 becomes 0.578 – 0.658).
- InpMaxBarsInZone (Default: 40): Maximum bars the EA will wait for breakout confirmation after price enters the Potential Reversal Zone (PRZ).
- InpInvalidateBufferPt (Default: 150): Extra buffer in points beyond pattern invalidation level (protects against wicks and spread spikes).
3. Breakout Confirmation Entry
- InpBreakoutPeriod (Default: 8): Donchian Channel period for entry confirmation. The EA waits for a candle close beyond the highest high (Buy) or lowest low (Sell) of the last N bars.
4. Risk Management
- InpUseRiskPercent (Default: true): If true, lot size is calculated based on account balance percentage. If false, fixed lot is used.
- InpRiskPercent (Default: 1.0): Risk percentage per trade.
- InpFixedLot (Default: 0.10): Fixed lot size when risk percent is disabled.
- InpSL_BufferPoints (Default: 150): Additional Stop Loss buffer in points.
- InpTP2_CDRetrace (Default: 0.618): Fibonacci retracement level of CD leg for TP2.
- InpMaxSpreadPoints (Default: 350): Maximum allowed spread (in points) to open a trade.
- InpSlippagePoints (Default: 30): Maximum allowed slippage.
- InpMagicNumber (Default: 20260703): Unique identifier for the EA’s trades.
5. Pattern Activation Toggles
The EA includes 19 independently switchable harmonic patterns (all enabled by default):
FlyingFox, Gartley, Lobster, Dragonfly, Cypher, Barracuda, AltFlyingFox, DeepLobster, WhiteSwan, BlackSwan, MaxBat, MaxGartley, MaxDragonfly, AltBarracuda, ALobster, ADragonfly, AFlyingFox, AGartley, SeaPony

Harmonacci Pattern EA is a rule-based tool for identifying and trading harmonic price patterns. It is not a guaranteed profit system. Past performance does not guarantee future results. Always test thoroughly on a demo account with your broker’s real conditions before using real capital. Never risk money you cannot afford to lose.
