The principle of banker's raising bid

Let me answer your question and add together:

When the stock price rises or is suppressed, the bookmakers don't eat every order, but when they operate, they don't fight independently, but attract more people (mainly retail investors) to join the battle with their own operations. When the trend is big, the dealer is resting and watching.

Of course, if you don't eat it all, you can't pull it up, but it's not necessarily all the goods eaten by the dealer. Bankers often buy and sell at the same time in order to save costs. Sometimes we can't even judge whether the dealer sucks or throws goods. However, one thing can help to judge, that is, in the low position, no matter how the dealer operates, it basically sucks goods, while in the high position, the dealer operates to throw goods. If you can't judge whether the current stock price is high or low, you can't use this help.

If the current price is 20 yuan, if you entrust the sales order of 19 yuan, you will certainly make a deal immediately, without waiting at all. If the current price is 20 yuan, you entrust 19 yuan to pay the bill. If the transaction price is lower than 19 yuan in the future, then you will definitely have a transaction. But it must be within one day. The entrustment is valid on the same day.

Stop loss, 1985gzz is right. By the way, the stop loss is set to prevent the loss from expanding.

Your supplementary question is:

Your bill buried in 19 is sure to sell. The banker (or not) can't exceed the price of your order. If he wants to call, he must close your order. Unless you cancel the order before the transaction.

Supplementary answer on July 2:

The landlord's question is very profound. It can be said that some investors who have been trading stocks for many years may not know how the transaction prices match.

Answer the first one first:

Stop loss is sold at current price. Stop-loss price is not for hanging. For example, 600030 CITIC Securities closed at 22.37 this morning, and your stop-loss price is 2 1.40 yuan. In other words, once the price falls to this level this afternoon, you will sell it to avoid further losses.

2. Now it's a big dive. If you want to make a quick deal, can you just hang the price limit?

All right. This can be done, and it can be done immediately. When China Southern Airlines dived, it was now 20. You hung up on 19, and at this time you dived into 19. 5. If another 19.5 offers at the same time with you, then the transaction will be made at your average price. If you hang up 19 first, and then pay the bill of 19.5, the transaction will be conducted with your 19 according to the time priority. If your 19 appears after someone else's 19.5 pays the bill, the transaction will be made on 19.5 according to the principle of time priority. Therefore, the key is to look at the time sequence of entering the system.

To sum up: 1. If there is a selling price first, the application price is higher than the minimum selling price, and the transaction is made according to the selling price; 2. If there is a purchase price first, and the application price is lower than the highest purchase price, the transaction shall be made at the purchase price. 3. Enter the system at the same time and take the average of the highest bid price and the lowest bid price.

Be thorough enough! ! ! ! !

3. For another example, I suddenly have something to go and want to stop the stock price from diving. Can't I bury a stop loss order? I will make a profit at the daily limit, and I will automatically stop the loss when it falls to my price.

The software I'm using at present can't, but some software may be possible. Sorry, I only used one software.
