The discontinuity of the price chart is called a “gap”. Usually breaks occur at the time of payment of dividends, or portend important events, i.e. when a major player has left the game and then the market is freed from his pressure and can change the trend. Gaps very often occur at the time of the opening of trading. Here are some examples.
