Triangle patterns describe a narrowing price range drawn between selected swings. Their shapes can help define breakout rules. The shape alone does not establish a reliable continuation pattern or a particular breakout probability.

The Three Shapes

An ascending triangle combines a roughly horizontal upper boundary with rising lows. A descending triangle combines a roughly horizontal lower boundary with falling highs. A symmetrical triangle has a falling upper boundary and rising lower boundary.

“Roughly horizontal” needs a tolerance if you want a repeatable test. Specify the number of swings, the lookback and whether boundaries use wicks or closes. Confirmed swings may require later bars, so record when the pattern first became available.

Any shape can break in either direction. Rising lows do not prove that buyers will eventually overwhelm resistance, and a descending triangle does not identify a final battle that sellers must win.

Define a Breakout Before It Happens

Decide whether your trigger is a trade beyond the boundary, a completed candle or a later retest. A closed-candle rule changes the entry price and can miss a fast move. A retest may never occur. None eliminates false breaks.

If you add a volume condition, state the feed and comparison period. Do not compare a partial bar with a complete bar or treat volume as evidence of named institutions. Test whether the filter adds value after costs.

A Measured Move Is a Planning Convention

Suppose an illustrative pattern's widest vertical range is $4 and its upward breakout level is $50. Projecting the height gives a $54 reference target. It is not a forecast or a likely destination established by the drawing.

A stop based on a recent swing creates a different risk distance from one on the opposite boundary. Calculate the resulting quantity and gross payoff, then allow for costs and adverse execution. A narrow stop can be crossed immediately without invalidating the entire larger pattern.

Avoid Hindsight in the Review

Save the original boundaries and record failed breakouts, patterns with no entry and trades that never reach the projected target. Do not move the apex or change the anchor points after seeing the result.

There is no universal 70% upward-break statistic or ideal “final third” entry region established for your chosen instrument and rules. Treat timing, retests and direction as variables to evaluate on a separate sample, rather than certainties attached to the pattern name.

Automatically reversing after a failed breakout is a second strategy with another order and loss exposure. Define and test it separately; being stopped out does not by itself justify an opposite trade.
