For example, in the monkey market, the quotation of a stock is:
In the morning, you sell a part (don't sell all of it, at least 1 lot) when it opens higher or higher, and then buy back the quantity you sold when it falls back, that is, you have completed a T+0 operation.
In the morning, you bought a part (the position is up to you) when you opened lower or fell back quickly, and then sold the quantity you bought that day when you rushed up, which means you completed a T+0 operation.
In fact, the essence is to "sell low and sell high, sell high and buy low" to earn the difference.
There are several conditions: 1. Make sure the position is not Man Cang before operation, because you don't know whether to buy or sell first. 2. After making a complete T+0, ensure that the number of stocks remains the same as before, that is, the number of stocks cannot be increased or decreased at last. 3. Generally, when doing T+0, look back at the historical trend to see if the intraday time-sharing fluctuation range is severe (2%-8%). If it's a K-strand on a loom (the intraday fluctuation range is kept within 1.5%), forget it, and it won't take much time and energy.
