Generally speaking, it reflects the size of active selling and active buying. Many people measure the strength of the stock trend on the day by the size of the internal and external disk, and use it as a reference for short-term trading. But in fact, can the ratio of internal and external stocks really accurately reflect the strength of stock trends? Since the dealer can make fake daily lines and turnover, can't he make fake internal and external orders? Therefore, it is necessary for us to study the details of the inner disk and the outer disk carefully. Friends who often watch the market should have had such an experience. When a stock is sideways in the low position and the dealer is in the stage of attracting gold, the inner disk is often larger than the outer disk. The specific situation is that the dealer presses the stock price with a larger list, and at the same time presses the stock price with a larger list at several price points. Many people are confused by the big selling orders above, and at the same time, they can't stand long-term sideways, so they sell them bit by bit, 3000 shares and 5000 shares. When the market is particularly depressed, I still see one or two hundred sell orders. At this time, the dealer is not in a hurry to raise the price to buy, but patiently accepts it a little. Only a few retail investors see that the stock price is no longer likely to fall deeply, and occasionally buy a little more than the banker, which forms a little peripheral market. As a result, active selling is far greater than active buying, that is, the internal and external markets are relatively large. Such stocks may look weak at the time, but they are likely to go out of the big market in the future, especially for a long time. But if the stock price is already high after full hype, the situation is just the opposite. The bill of the day is greater than the selling bill. Banks use large amounts of money to catch up with retail investors. He paid bit by bit and then raised the price. In fact, the original big order has been withdrawn and hung up. It seems that everyone is moving forward bravely. In fact, retail investors have been regarded as pawns of a river. Occasionally, a large family in the village suddenly smashed the tray below, and we saw that the tray below was so fragile. The reason is that everyone was rushed to the front. I'm afraid that some people who haven't bought it will quickly withdraw their orders and hang up. This is a gesture of never giving up until they buy it. In fact, there are not many orders below, so the dealer has to make up a big order as soon as possible to resist. At this time, the outer disk is much larger than the inner disk. Do you think this is a good thing? Short-term follow-up, fast forward and fast out may be ok, if you are not careful, you may get stuck, so you may not be able to turn over for half a year. The above mentioned are two typical situations when the dealer finances the shipment. At this time, the signals provided by the internal and external markets are contrary to our usual understanding, so the first thing to do is to find out where the stock price is. Without preconditions, it is impossible to draw meaningful conclusions simply through analysis. Of course, in many cases, the stock price is neither high above nor lying motionless on the floor, but jumping up and down in the ascending channel, or taking the descending channel, or doing box oscillation or narrow sideways. How to judge the meaning of the inner disk and the outer disk at this time? When the stock rises along a wave with a certain slope, the outer disk is stronger than the inner disk before the high point of each wave. On the disk, it is common to push big orders layer by layer or to buy them actively. During the sprint, the price and quantity rose together. At this time, we should pay attention to gradually reducing pounds on rallies. When the stock price peaked, the inner disk was stronger than the outer disk. At this time, it is necessary to leave in time, because even if there is a high point in the future, it will be necessary to retreat. We can wait lower. Later, the stock price fell to a certain extent and was supported by a certain moving average. (Source: Stock Market Classic) Although the internal market is still stronger than the external market, the stock price no longer falls. In the day market, it is common for big orders to cross there. Although it doesn't go up, how much is collected? This is called bargain hunting. At this time, we might as well participate in a small amount. Even if the ascending channel is broken and the previous high point becomes the highest point, we can at least hope for the double head or the top of the head and shoulders. The above refers to the situation that the stock price runs in the rising channel, while the situation that the stock price runs in the falling channel is just the opposite. Only in the short-term rebound process, the outer disk will be larger than the inner disk. In most cases, the inner disk is larger than the outer disk. For such stocks, we will not participate. As for box-type oscillating stocks, because the trading volume tends to be enlarged and reduced regularly, the timing of intervention and withdrawal is better grasped, and the characteristics of judging by internal and external disks are roughly similar to those of stocks taking the upward channel. Narrow consolidation of stocks is often accompanied by a sharp drop in trading volume, and the reference significance of internal and external markets is even smaller. Because the size of the inside and outside disk must be combined with the size of the transaction volume, when the transaction volume is extremely small or large, it is often a pure retail market or a large number of bookmakers, and the inside and outside disk loses its own meaning and there are too many false components. In addition, there are two extreme cases, namely, the internal and external disk at the daily limit and the internal and external disk at the daily limit. When the stock price is at the daily limit, all transactions are internal, but the determination to rise is quite firm. We cannot judge that the trend is not good just because the internal market is much larger than the external market. When the stock price is at the daily limit, all transactions are outside the market, but the downward momentum is full. It cannot be said that the trend is strong because the outside market is much larger than the inside market. In a word, the size of the inner disk and the outer disk is helpful to judge the trend of the stock, but it must be judged by combining the position of the stock price and the size of the trading volume at the same time, and more attention should be paid to the big form of the stock trend, and we must not pay too much attention to the details and ignore the overall situation. In the current Chinese mainland stock market, changing hands can be simply understood as describing the sale of stocks from one person to another, that is, buying and selling. In securities trading, it is very limited to describe the market information only by a price dynamic, and the number of transactions, that is, the amount of transactions, is a very important reference standard. In the futures trading or securities trading market in other countries and regions, you can be both a bull and a bear, which refers to the transfer of securities, securities options or commodities when trading between bulls or bears. Simply put, changing hands is changing people. You sold 65,438+0,000 shares to another person, and these 65,438+0,000 shares changed from your hand to another person's hand. This is what is the commission ratio when changing hands, and it is an indicator to measure the relative strength of buying and selling in a period of time. Its calculation formula is: commission ratio = [(number of entrusted buying hands-number of entrusted selling hands: the sum of the entrusted selling hands of all stocks in the last three files. The commission ratio ranges from+100% to-100%. When the commission ratio is positive and the commission ratio is large, it shows that the market buying is strong; When the commission ratio is negative and the negative value is large, it shows that the market selling is strong; The commission ratio ranges from-100% to+100%, indicating a process in which buying is gradually strengthened and selling is gradually weakened. On the contrary, from+100% to-100%, the process of buying gradually weakened and selling gradually strengthened.
