The rounded bottom pattern and the cup and handle pattern are obviously comparable in appearance and formation.
A rounding bottom pattern, however, is a bullish trend reversal pattern that appears in some cases after a downtrend or long price consolidations.
Whereas a cup and handle chart pattern is a bullish continuation pattern that may see increased price action and bullish momentum in volume and price of an asset.
Unlike the cup and handle chart pattern, the rounded bottom pattern does not include the handle as seen on a cup and handle pattern but rather features a neckline and a rounded bottom.
