The Leonardo Harmonic Mode Indicator is a specialized tool for analyzing harmonic structures. It is designed to detect potential price reversal areas based on Fibonacci ratios . Structurally, it is similar to the bat pattern, but shows significant differences in the level and proportions of the figures, making it unique.

The Leonardo pattern consists of five labeled legs XA , AB , BC , CD , and AD . If correctly identified, these waves can help identify potential entry and exit areas . Technical analysis . Key ratios like 50% , 88.6% , and 261.8% play a key role in the formation.

Leonardo harmonic mode indicator table

Specifications Leonardo harmonic mode indicators are summarized in the following table:

Indicator Overview

In most harmonic indicators, Fibonacci levels are broadly similar. However, the Leonardo construction uses the following standard leg setup:

• XA: Initial price change, can be any fluctuation, no special criteria are required
• AB: Corrective leg moving relative to XA, usually retracing 50% of XA
• BC: moves relative to AB and should be 38.2% or 88.6% of AB
• CD: The last stop is in the opposite direction of BC
• AD: The total distance from A to D must be 78.6% XA for the mode to be valid

The CD leg is calculated in two situations:

• If BC = 38.2% AB → CD extends to 112.8% of BC
• If BC = 88.6% AB → CD usually reaches 261.8% of BC

Uptrend Conditions

In the EUR/CAD chart of the currency pair, point D is marked as an important area within the Leonardo pattern after XA, AB, BC and CD are fully formed.

Positioning D within the sensitive Fibonacci zone increases the likelihood of a bearish to bullish reversal.

downtrend conditions

Leonardo pattern on EUR/USD chart. After formation from XA to CD, point D is located in a key area considered a reversal area.

The Fibonacci relationship between AB, BC , and CD confirms the validity of this structure and shows that D has a higher probability of a bearish move.
