What it looks like
Triangle breakout up
Falling highs and rising lows form a narrowing triangle. This variant completes when price closes above the upper boundary.
The triangle completes only on a close above the upper boundary.
Exact machine rule
Two confirmed falling highs and two rising lows form converging boundaries over 12–120 candles; the signal closes above the upper boundary.

Optional practice
Check your recognition
Select the chart where the formation is already complete.
Try it
A dotted candle is still forming; a solid candle is closed. Only one chart contains a completed signal.
The exercise checks recognition. Historical outcomes are calculated separately and do not promise a price move.Three features of Triangle breakout up

The triangle completes only on a close above the upper boundary.
Similar formations and limits of one example
Time spent inside a triangle is not a signal; the closing breakout is required. The shape identifies an event to research. It does not predict the next move or provide a trading signal by itself.
One formation does not establish the probability of a move. The historical comparison measures outcomes against a comparable background for each configuration.
