1. Open positions; Refers to the sum of the number of contracts opened by buyers and sellers that have not been closed in reverse. The size of positions reflects the size of market transactions, as well as the differences between long and short sides on the current price. For example, suppose that when two people are counterparties, one person opens a position to buy a contract and the other person opens a position to sell a contract, then the position is displayed as 2 contracts. 2. The inner disk and the outer disk are equivalent to the inner disk and the outer disk in stock software. For example, those entrusted with the seller's transaction are included in the "outer disk" and those entrusted with the buyer's transaction are included in the "inner disk". "Outer disk" and "inner disk" add up to volume. During the analysis, because the seller's entrustment to clinch a deal is included in the outer disk, if the outer disk is large, it means that most of the selling prices are picked up, which shows that the buying potential is strong; If the buyer's transaction is included in the inner disk, if the inner disk is too large, it means that most of the buying prices are willing to sell, indicating that the seller has greater strength. If the inner disk and the outer disk are roughly similar, the buying and selling power is equal.

3. Chief hand; Refers to the total number of lots that have been sold in this contract up to now. In China, a transaction is counted as a 2-hand transaction based on one hand of each party, so you can see that the mantissa is double digits.

4. Yesterday's settlement: refers to yesterday's settlement price. Settlement price (different from yesterday's closing price) refers to the weighted average price of the transaction price in the last hour of a futures contract according to the volume. If the contract is a new listed contract, the calculation formula of the settlement price of the day is: contract settlement price = benchmark price of the contract+settlement price of the benchmark contract today-settlement price of the previous trading day of the benchmark contract.

5. commission ratio: refers to the index used to measure the relative strength of buying and selling orders in a period of time, and its calculation formula is: commission ratio = [(number of entrusted buyers-number of entrusted sellers) ÷ (number of entrusted buyers+number of entrusted sellers) ]× 1%

6. Position difference: short for position difference, which means that the current position corresponds to yesterday's closing price. If it is positive, the position will increase today; if it is negative, the position will decrease. The position difference is the change of the position. For example, the position of the stock index futures contract in November today was 6, lots, while it was 5, lots yesterday, so the position difference today is 1, lots. In addition: there is also a change in the position difference in the transaction column. Here, it refers to the comparison between the position change caused by the current transaction order and the immediate position of the previous one, whether to increase or decrease the position.

7. Multi-opening: short for multi-position opening, which means that the position is increased, but the added value of the position is less than the current position, and it is active buying. For example, suppose four people are the counterparties, in which A hangs out one hand for selling and closing positions, B hangs out ten hands for selling and opening positions, and C sees that there are 11 hands at the selling position, that is, five hands for buying and opening positions are hung out at the current price, and the disk display will be: multi-opening, the spot turnover is 1 hands, and the position difference is +8 hands (because A hangs out one hand for closing positions first); When D buys 2 open lots later, it will show: double open lots, 4 lots, and the position difference is +4 lots (at this time, all the pending orders are sold and opened by B)

8. Empty open; Short for short position, which means that the position has increased, but the added value of the position is less than the current position, and it is active selling; For example, the selling and buying in the above example can be reversed.

9. Double opening; It means that in a certain transaction, the opening amount is equal to the spot amount, the closing amount is zero, the position is increased, and the difference is equal to the spot amount, indicating that both long and short positions have increased their positions

1. Double leveling: it means that in a certain transaction, the opening amount is equal to zero, the closing amount is the spot amount, the position is reduced, and the difference is equal to the spot amount, indicating that both long and short positions have reduced their positions.

11. Multi-exchange and short-exchange: short for multi-exchange and short-exchange. If in a certain transaction, the amount of open positions and flat positions are equal to half of the current transaction volume, and the amount of positions remains unchanged, it means that the long positions and short positions have not changed, but some positions have been transferred between long positions or short positions. Combined with the state of internal and external markets, we define the state of the transaction as multi-exchange and internal markets as multi-exchange.

12. Multi-level and Empty-level: short for long position closing and short position closing. Long position closing refers to the decrease of positions, but the absolute value of the increase of positions is less than the current quantity, and it is active selling; Short position refers to the decrease of positions, but the absolute value of the increase of positions is less than the current amount, and it is active buying. For example, suppose three people are the counterparties, in which A has 5 long positions, B has 5 short positions and C has no positions; If Party A wants to close some positions, it will sell 3 positions; if Party C thinks that the market will fall, it will sell 2 positions; if Party B also wants to close positions, it will sell 5 positions at the current price (selling price), and the disk will show: empty (short position), 1 hands on hand, and the position difference is-6. If it is a long position, it is to take B as the initiative to hang out the position, and A can then close the position.
