If there is a sudden heavy volume, then there will be an upward breakthrough in the plot ratio index map. The steeper the volume, the greater the volume (which can be ignored when the market opens).

If there is shrinkage, the ratio index will drop.

The volume ratio is greater than 1, indicating that the average volume per minute on that day is greater than the average of the past five trading days, and the transaction is enlarged;

The volume ratio is less than 1, indicating that the current transaction is not as good as the average level in the past five days, and the transaction is shrinking.

Volume ratio is an index to measure the relative volume, that is, the ratio of the average volume per minute after the opening of the market to the average volume per minute in the past five trading days. (Feel the strongest attack band in China stock market ...)

The formula is:

Volume ratio = total volume/(average volume per minute in the past 5 days × cumulative opening time of the day (minutes))

When the equivalence ratio is greater than 1, it means that the average transaction per minute on that day is greater than the average of the last five days, and the transaction is hotter than the last five days; When the equivalence ratio is less than 1, it means that the current transaction is not as good as the average level of the past five days.
