The difference is that ordinary business must have a transaction price when entrusted, and the entrustment may not be completed. Lightning selling and buying are traded according to the market price at that time, and individuals do not need to fill in the exact price (that is to say, in fact, the stock prices we see on the exchange are all from Shanghai and Shenzhen, and there is a time difference between the two places, which may be a few seconds or 10 second, so what we see is not necessarily the latest price). Therefore, it is more likely to place an order by lightning than ordinary ones, but the price is beyond your control. Generally, when the market is good, it is sold or bought by lightning, chasing up or suddenly diving sharply to get rid of it.

At the earliest, when filling out forms at the counter, the column of buying or selling was usually filled in, but it was not allowed later.
