What does it mean that the stock is T?

Referred to as "t+0", there are warehouses and funds trading on the same day. In order to achieve the effect of sharing the cost equally, the abbreviation is: do T.

There are two ways to do t: positive t and inverted t.

1. Buy first and then sell. This is called positive T: buy stocks when the price is low, and then sell the stocks in the bottom position after the stock price rises, achieving the effect of t+0.

2. sell first, then buy, called inverted t: sell first when the stock opens higher, and then buy back the stock with funds after the stock price falls, and at the same time achieve the effect of t+0.
