Long position: IF (short > =REF (short, 1), short, draw null), colored, line thick 2;

At this point, the trend in the indicator line is only a line shape, which can clearly show whether stocks should be short or long, and make a basic analysis combined with the degree of pull-up, to help investors identify the basic position of trading points in actual combat.

What is observed from the figure is the trend pattern of each measuring column, which shows the change of trading volume, which can help investors analyze the change of import and export volume, and is an auxiliary tool for selecting individual stocks in the trend of moving average.
