Broadening Triangle Pattern — what it is and how to read it

Bullish pattern Classic and harmonic chart patterns

Highs rising, lows falling (a megaphone): swings are growing, the market is undecided and full of traps. The direction is set by the breakout: a close above the last high = up (the card's trigger), a close below the last low = down. keep positions small.

How to read it

A bullish structure is only a candidate until its trigger (neckline / breakout level) is broken. StockFortuna draws the ▲ marker only on a green candle that closes above the trigger — a description of what the chart did, not a recommendation.

Our backtest: ⚪ Not backtested (added 9 Sep 2026) — information on the chart only; it does not enter the buying system.
