The psychology behind the ascending triangle is buyers steadily growing more aggressive while sellers defend a fixed price ceiling, creating a battle that typically resolves in favor of the bulls. The pattern visualizes an ongoing battle between bulls and bears: bulls keep pushing the stock up until they get overpowered by sellers at the horizontal resistance, but though sellers push price down, they cannot reach previous lows because buyers are persistent and price sets a higher low.
Buyers are increasingly optimistic, creating higher lows, while sellers resist at a set price level, showing confidence in keeping prices down.
Some buyers patiently wait for the breakout, placing higher bids, and once the pattern gets confirmed, more buyers rush in, pushing the price up.
