How is the A-share daily limit realized?

Let's just say that the fluctuation range is 10%. After the price rises 10% or falls 10%, your trading software will not let you enter a higher or lower price. We can only trade at this price. There is no need to stop it. There were many people who wanted to sell, but no one wanted to buy. Of course, there is no deal. Hehe, it's not that you're not allowed in. There is a price limit. 10 yuan's stock fell to 9 yuan, with a daily limit. You can enter purchase or sale orders for 9 yuan and above. But if everyone is selling at this time and you want to sell, you have to queue up. But not less than 9 yuan.
