Generally speaking, stocks cannot be bought and sold on the same day, because the trading of stocks is T+ 1, which is the rule.

1. If you buy it on the same day, you can't sell it on the same day, but you can sell it the next day.

2. No, the trading mechanism of stocks is t+ 1, and warrants, futures and foreign exchange can be used.

3, buy the same day can not sell the same day! It won't be sold for 24 hours.

4. the stock market is T+ 1, which means that if you buy on the same day, you can only sell it on the next trading day, not necessarily the next day (for example, you can't sell it on weekends or closed days).

5. Because it is a trading system of T+ 1, the things bought on the same day cannot be sold on the same day, but the disguised T+0 operation can be realized through securities lending, that is, buying on the same day and selling on the same day.
