The numbers in the current lot column indicate the number of batches of transactions at that transaction price at that moment. The color red represents that the current transaction price has increased compared with the previous transaction price, and the color green represents the transaction price. It is down compared to before, and the gray color means that the transaction price is the same as before.

The number in the position increase column indicates the impact of the transaction price and transaction quantity on the position at that moment. If the number is positive, the position is increased. If the number is negative, the position is held. The amount decreases. If it is 0, the position remains unchanged. The color change principle is consistent with the current color change in the hand.

Position: refers to the total number of contracts opened by buyers and sellers that have not yet implemented reverse closing operations. The size of the position reflects the size of the market transaction, and also reflects the size of the disagreement between the long and short parties on the current price.

Position difference: It is the abbreviation of position difference, which refers to the difference between the current position and the position corresponding to yesterday's closing price. If it is positive, the position will increase today, and if it is negative, the position will decrease.

Settlement: refers to the settlement price of the trading market up to now. This price is constantly changing until the final value of the settlement price is determined at the closing time.

Yesterday’s settlement: refers to yesterday’s settlement price. Internal offer and external offer: those entrusted with the seller's transaction are included in the "outer offer", and those entrusted with the buyer's transaction are included in the "internal offer". The sum of "external market" and "internal market" is the trading volume. During the analysis, since the orders from sellers are included in the external market, if the external market is very large, it means that most of the selling prices have been picked up, indicating a strong buying trend; while the orders from buyers are included in the internal market, and if the internal market is too large, it means that most of the selling prices are there. There are people willing to sell at the buying price, which shows that the seller has greater power. If the internal market and external market are roughly similar, the buying and selling power is equal.
