What is Triangle pattern?
Uchburchak shakli
In short
A consolidation in which the range keeps narrowing. Ascending: flat top, rising lows. Descending: flat bottom, falling highs. Symmetrical: both lines converge. The signal is a close outside a line.
Also known as: ascending triangle, descending triangle, symmetrical triangle
A triangle is a consolidation pattern in which the trading range gradually narrows. Two trendlines — one through the highs and one through the lows — converge.
Three types
- Ascending triangle — flat top (the same resistance) and rising lows. Buyers keep stepping in higher; it often breaks up.
- Descending triangle — flat bottom (the same support) and falling highs. Selling pressure builds; it often breaks down.
- Symmetrical triangle — both lines converge. Direction is unclear; it often breaks in the direction of the prior trend.
The signal
The key rule is a close outside a line. Trading inside the triangle is noise; leaving it is a breakout. Volume usually dries up inside the triangle and should expand sharply on the breakout.
Target and stop
The measured move: the height at the triangle's widest point is projected from the breakout point. The stop usually goes beyond the last low (or high).
Limitations
A breakout very close to the apex, when the pattern has almost "run out", tends to be weaker. False breakouts are common too — especially in symmetrical triangles.
A flat ceiling and ever higher lows — buying pressure is building. It often ends with an upside breakout, but there is no guarantee.
Support is flat at $80 while the highs keep falling: $90, $87, ~$84.4 — sellers accept less each time. The widest part is $10, so a break of $80 points to about $70. For a halal investor it is a signal to sell and wait.
Example
Illustrative (ascending triangle): for two months a stock could not get above $60, while its lows rose to $52, $55 and $57.50.
- Height at the widest point: $60 − $52 = $8
- Price closes at $60.80 — above resistance, on 1.8 times average volume.
- Target: $60 + $8 = $68
- Stop: below the last low, at $57.30. Risk: $60.80 − $57.30 = $3.50
- Reward to target: $68 − $60.80 = $7.20 → R:R ≈ 1:2.1
Mistakes and tips
Don't enter inside the triangle guessing "which way it will break" — wait for a closing breakout.
If volume doesn't expand on the breakout, the risk of a false breakout is high.
Draw the triangle's lines through at least two highs and two lows; a line drawn from a single point is unreliable.
Frequently asked questions
- Does an ascending triangle always break up?
- No, only often. Sometimes price breaks the lower line, so the signal is taken only once a close confirms the breakout side.
- Which way does a symmetrical triangle break?
- You can't know in advance; statistically it more often breaks in the direction of the prior trend. That's why many traders watch both sides and wait for a close.
