Frequently Asked Questions

The Harmonacci Patterns indicator is a comprehensive harmonic pattern recognition tool for MetaTrader that automatically detects 19 distinct price formations based on Fibonacci ratios. It stands out by incorporating Donchian breakouts for signal confirmation, enhancing trade reliability. In addition, it visualizes the Potential Reversal Zone (PRZ), plots stop-loss and take-profit levels, and offers historical pattern tracking with detailed ratio and projection overlays.

Signals are triggered when a completed harmonic pattern is followed by a Donchian breakout in the expected direction. This two-stage filtering process helps reduce false signals and aligns with more disciplined, rule-based trading strategies.

The PRZ is a key confluence area where multiple Fibonacci retracement and extension levels intersect, indicating a likely price reversal. The Harmonacci Patterns indicator calculates and displays this zone using vector-independent projections aligned with the specific harmonic structure, allowing traders to visually assess high-probability turning points.

Absolutely. You can choose which harmonic patterns to scan for, modify the colors for bullish and bearish formations, change the size and style of chart labels, and toggle the visibility of Fibonacci ratios, projections, and SL/TP levels. Alerts and breakout visuals can also be tailored to your preference.

Yes, the indicator can repaint in certain situations. If a pattern is still forming and a Donchian breakout is not definitive, the pattern may continue expanding and adjust its structure dynamically. This behavior is intentional and aligns with real-time market evolution, but traders should be aware that signals may change if a breakout fails or the pattern does not finalize.

Some of our indicators perform deep analysis of price history, especially those that calculate Fibonacci levels, structure, or multiple signal legs. If it feels slow to load, try lowering the "Max History Bars" setting in the input parameters. This limits how far back the indicator analyzes and improves responsiveness.

The indicator provides sound, visual, email, and push notifications. You can enable alerts for the appearance of new patterns, confirmed breakouts, or both. This ensures you're promptly informed of trading opportunities, even when you're away from the chart.

The indicator is heavily inspired by the harmonic trading methodology introduced by Scott M. Carney. However, due to trademark restrictions, some pattern names have been changed to more self explanatory alternatives. Despite the renaming, the underlying structure and Fibonacci logic of the patterns remain faithful to the original concepts.
