Novice stock, what happened to Tianye shares these days?

The limit of 10% is normal as long as there is no 105.

Actually, it's hard to say

On the first day of listing, there is no limit on the decline of new shares, and the st class is limited to plus or minus 5%, that is, the maximum increase is 5%/ trading day, and the maximum decrease is 5%/ trading day.

As for the opening price you mentioned, it is much worse than the closing price of the previous day, which is called low opening and high going.

If today's opening price is higher than the closing price of the previous day, it is called high opening, otherwise it is called low opening.

A lot of knowledge, learn slowly, and you can't finish it at once.
