Volume ratio is the processing of stock trading data, and T+0 is the trading rule of the exchange. There is no correlation between them. It can't be said that a large plot ratio can make T+0.

What's the ratio? What is the quantity? What is the quantity?

This depends on the concept of ratio.

Ratio is an index reflecting the relative benchmark value of stock or futures trading volume. The benchmark value is generally set as the average trading volume of the previous five trading days. Ratio formula displayed on disk:

Volume ratio = current turnover/(average turnover 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 transaction of the day is enlarged, and the part exceeding 1 is the transaction magnification. Generally, if the ratio is less than 1, the ratio is not large, and if it exceeds 2, it will be large. In addition, it is necessary to combine the turnover rate to judge the amplification of the transaction.
