Through the size and proportion of the number of external and internal markets, investors can usually find out whether they are actively buying or actively selling. In many cases, they can find the trend of bookmakers, which is a more effective short-term indicator.
However, investors should pay attention to the combination of low, medium and high turnover rate and the total turnover rate of the stock when using external and internal plates. Because the number of outer disk and inner disk is not always effective, many times the outer disk is large and does not necessarily rise; If the internal market is large, it may not necessarily fall.
