A phenomenon where wave 5 of an impulse briefly exceeds the upper channel line before reversing sharply.
Description
A throw-over occurs when wave 5 punctures the channel line that connects the ends of waves 1 and 3. This false breakout is followed by a sharp reversal. Throw-overs are often accompanied by low volume and are a warning sign that the impulse is nearing completion. The same phenomenon can occur in diagonal triangles.
Key Points
- Wave 5 briefly exceeds the upper channel line, then reverses sharply
- Often accompanied by low volume — a sign of exhaustion, not genuine breakout
- A throw-over signals that the impulse wave is likely complete
- Also observed in diagonal triangles (ending diagonals)
- Distinction: a true breakout continues strongly; a throw-over quickly retreats back inside the channel
