Definition

Harmonic Patterns are geometric price structures that use Fibonacci ratios to identify potential reversal zones in financial markets.

These patterns attempt to identify areas where:

• Trend exhaustion occurs.

• Buyers or sellers become vulnerable.

• Price may reverse.

• Risk can be clearly defined.

The central idea:

Certain price movements create repeating geometric relationships that reveal areas where supply and demand may shift.

Beginner Explanation

Imagine a mountain climber.

A climber does not suddenly reverse direction randomly.

There are signs:

• Momentum slows.

• Energy decreases.

• Conditions change.

Markets behave similarly.

A strong move eventually reaches areas where:

• Buyers become exhausted.

• Sellers become aggressive.

• Previous participants take profits.

Harmonic patterns attempt to identify those exhaustion points.
