A rounding bottom is a long-term bullish chart pattern that forms after a downtrend, where price gradually shifts from selling pressure to buying interest in a smooth, curved shape (like a “U”). It shows that bears are slowly losing control while buyers are quietly accumulating, leading to stabilization and then a steady rise. Volume is usually low near the bottom and starts increasing as price moves upward, and a confirmed breakout above the resistance level signals a potential trend reversal from bearish to bullish.
