To play the board, we must catch the strongest, that is, the leading stocks we often say. The start-up of any sector needs the guidance of leading stocks. Individual stocks are most prone to daily limit in the breakthrough acceleration stage. If the moving average system does not form a long arrangement and is not in the breakthrough acceleration stage, the persistence of the daily limit is not reliable enough. Only at the critical point of breakthrough acceleration, the main force adopts the daily limit breakthrough, and the market outlook is huge. Almost all money-making operations should pay attention to the irreversible market trend. When the fluctuation of hot spots and the money-making effect at the end of adjustment appear, it is the best time to grasp the daily limit. When the stock price, trading volume, moving average shape, market operation time and current market hot topics vibrate, continuous daily limit will be born, which is the requirement of the joint efforts of the market.
