The white line is the change of position. The hollow column represents the total turnover of the current cycle. When the column is red, it means that the closing price of the current cycle is greater than the opening price, and the price is rising. When the column is blue, it means that the closing price of the current cycle is less than the opening price, and the price is falling. The red solid column is the number of outer disks. As shown in the figure, 982.00 (24: 76) shows that the outer disk accounts for 24% and the inner disk accounts for 76%. The red solid column is 24% of the length. Generally, when the external disk is larger than the internal disk, it means that the active buying increases and the price rises.

It is difficult to judge the price trend only from the volume chart.
