1. If the original variety is locked, the intraday price difference can be obtained through this operation, so as to reduce the cost, untie it as soon as possible, or even turn it over. After all, suppose one-on-one "T+0" operation, after the operation is successful, there are still so many chips, but the cash on the books has increased, which means that the cost of holding chips has decreased. Otherwise, blindly hide, wait passively, and often don't know to wait until the Year of the Monkey. Passive unwinding is not as good as active unwinding.

2. If you don't lock positions, but take profits, if your chips double, you may bring double income on the day of the rally. Use the stocks and cash in your hand and do "T+0" with the help of intraday fluctuations. The number of existing stock varieties bought on the same day is the same as the original one, or it may be different. After it rises to a certain height, all or part of the original same variety will be sold, so as to realize low purchase and high sale on the same day and obtain the price difference.

Investors who allocate stock index futures funds should pay attention to the following matters in specific operations:

1. Pay attention to whether there is a faucet in the same plate, which is a relatively certain starting opportunity. If there is a leader, and the leader touches the daily limit, the same sector of his stock may have follow-up actions, and you can take this opportunity to immediately intervene and stagflation.

2. It is required to judge whether the stock market and the stock can close the positive line on the same day, or whether the stock can hit a high point on the same day. Often, the trend of the market in the first 30 minutes, if the first 30 minutes are at the highest point, is conducive to the use of intra-day reverberation to do "T+0" operation.

3. After the intervention, pay attention to whether the leader in the same sector can seal the daily limit. If not, once the faucet turns around, he will follow the original chips on the windward plate for "T+0" operation without hesitation to keep a few cents or even more short-term profits. Otherwise, if the exit is not timely, the new chips used for "T+0" operation on the subsequent table are in danger of being locked up in a short time.
