Triangle patterns are consolidation formations where price range narrows over time. They are extremely common on NSE stocks and represent a battle between buyers and sellers. The direction of the breakout reveals who won — and gives a measured price target. Three main types cover most situations you will encounter.

All Three Triangle Types

Ascending Flat top + Rising lows Bullish continuation Descending Flat bottom + Falling highs Bearish continuation Symmetrical Falling highs + Rising lows Breakout direction = signal

Ascending Triangle

Flat resistance line + rising support line. Buyers are getting more aggressive (higher lows) while hitting the same resistance. Usually breaks upward.

Buy Entry: Price closes above the flat resistance on high volume
Stop Loss: Below the most recent higher low
Target: Flat resistance + triangle height (widest part)

Descending Triangle

Flat support line + falling resistance line. Sellers are getting more aggressive (lower highs) while the same support holds. Usually breaks downward.

Short Entry: Price closes below the flat support on high volume
Stop Loss: Above the most recent lower high
Target: Flat support − triangle height

Symmetrical Triangle

Falling highs + rising lows converging to a point. This is a neutral pattern — either side can win. Wait for the breakout direction before trading.

Trade the breakout direction:
Bullish breakout: Buy above upper trendline on volume
Bearish breakout: Short below lower trendline on volume
Stop Loss: Opposite trendline
Target: Pattern height added/subtracted from breakout point
On NSE, Ascending Triangles form most commonly during sector rotation rallies — when one sector is leading and individual stocks in that sector form flat tops as they consolidate before continuing higher. These are high-probability bullish continuation setups.
Triangles can produce false breakouts — especially on low volume. Always wait for a candle close outside the triangle, not just an intraday pierce. Volume above 1.5× the 20-day average significantly increases reliability.
