The Leonardo Harmonic Pattern Indicator is a specialized tool for analyzing harmonic structures. It is designed to detect potential price reversal zones based on Fibonacci ratios. Structurally, it resembles the Bat Pattern but shows notable differences in numerical levels and ratios, making it unique.
The Leonardo pattern comprises five price legs labeled XA, AB, BC, CD, and AD. These waves can help determine potential entry and exit zones if identified correctly in Technical analysis . Key ratios like 50%, 88.6%, and 261.8% play a critical role in the formation.

Uptrend Conditions
In the EUR/CAD currency pair chart, point D is marked as a significant zone within the Leonardo pattern after the complete formation of XA, AB, BC, and CD.
Positioning D within a sensitive Fibonacci area increases the probability of a reversal from bearish to bullish.

Downtrend Conditions
The Leonardo pattern is accurately identified on the EUR/USD chart. After the formation from XA to CD, point D is positioned in a key area considered a reversal zone.
The Fibonacci relationshipsbetween AB, BC, and CD confirm the structure's validity and suggest a higher probability for a bearish move from D.

Conclusion
The Leonardo Harmonic Pattern Indicator, built on an accurate Fibonacci-based structure, allows for analyzing potential reversal formations across all timeframes.
While similar to the Bat Pattern, its specific retracement levels and high precision make it a distinctive tool for identifying market-sensitive zones in MetaTrader 5.
What's the main difference between Leonardo's Harmonic and other harmonic indicators?
The primary difference lies in the unique Fibonacci levels and the indicator's precision in identifying point D as the key reversal zone. It shares structure with the Bat Pattern but differs in retracement logic.
Can both bullish and bearish patterns be viewed simultaneously?
Yes, simultaneous detection is possible by enabling both the BullishPattern and BearishPattern options.
