External quotation: a transaction concluded at the selling price. Sales statistics are added to the external disk.
The two data of inner disk and outer disk can be used to judge the strength of buying and selling rights. If the number of external disks is greater than the number of internal disks, the buyer is stronger; If the number of inner disks is greater than the number of outer disks, the strength of the seller will be stronger.
Through the size and proportion of the number of external and internal markets, investors can usually find out whether they are actively buying or actively selling. In many cases, they can find the trend of bookmakers, which is a more effective short-term indicator.
Extended data:
Simply put, the outer disk actively buys and the inner disk actively sells. The futures market display column will have the selling declared price and buying declared price of the corresponding contract variety (futures software will generally display a market), that is, the selling price and buying price, and the latest price is the transaction price at that time.
For example, at a certain moment, the declared selling price of soybean contract is 460 1 yuan/ton, and the buying price is 4600 yuan/ton. In this way, if you want to buy soybeans, the contract price can be 4600 yuan/ton, or you can choose 460 1 yuan/ton. Of course, if you buy at 460 1 yuan/ton, you can make a deal right away. At this time, the latest price is available.
And if it is bought at 4600 yuan/ton, this trading volume is included in the inner disk. Of course, on the other hand, if you want to sell it, you can make a deal at 4600 yuan/ton, and the latest price shows 4600 yuan/ton.
The number of internal disks plus the number of external disks is the total turnover.
The strength of buying and selling power can be roughly judged by two data of internal and external disk. If the outer disk is larger than the inner disk, it means that there are many active purchases and buyers have a strong willingness to buy goods. The buyer pushes up the price by constantly raising the quotation, so as to purchase as soon as possible, and the price is bullish in the short term. If the inner disk is larger than the outer disk, on the contrary, the seller has a strong willingness to sell goods, and the selling price pushes the price down by constantly lowering the price quotation, thus shorting in the short term.
This data can be used as a reference for market judgment. Theoretically, the outer disk is obviously larger than the inner disk, indicating bullish, and the inner disk is obviously larger than the outer disk, indicating bearish.
However, in practice, we should not only look at unilateral index data, but also consider many factors. Reference can be made when the disparity between the internal and external markets is large, and there is no reference basis when the disparity is large. In addition, we must combine the trading volume and futures price to determine the buying and selling direction.
