Triangle
A triangle is a narrowing consolidation bounded by converging lines. An ascending version has horizontal resistance and rising lows; a descending one has horizontal support and falling highs; a symmetrical version has both boundaries sloping inward. Its name establishes neither breakout direction nor a universal success percentage.
Illustrative example
How does it work in practice?
Assume highs near 110 with successive lows of 100, 103 and 106. Horizontal resistance and rising support form an ascending-triangle candidate; a downside breakout remains possible despite the pattern's name.
A case to work through
One horizontal boundary
Hypothetically, highs remain at 80 while lows rise 70→73→76.
- The upper boundary is horizontal and the lower rises, fitting an ascending-triangle candidate.
- It is not a symmetrical structure with a falling upper line.
What follows? Record the variant and break conditions for each boundary.
Example boundary: Point selection needs rules; a downward break remains possible.
A useful distinction
Triangle / Wedge
A triangle can have differently directed boundaries or one horizontal line; a wedge has both sloping in the same direction.
