The main basic indexes of technical analysis of futures prices are opening price, closing price, highest price, lowest price, trading volume and positions. 1, the price generated in call auction five minutes before the opening price. 2. The final transaction price on the closing day. 3. The highest transaction price on the day of the highest price. 4. The lowest transaction price on the day of the lowest price. 5. Volume refers to the number of contracts of a commodity futures in a certain trading time. In the domestic futures market, the sum of trading volume is used to calculate trading volume. 6. Open position refers to the quantity of a commodity futures contract that has not been hedged and delivered in kind after being bought or sold, also known as open position or short position. Buyers and sellers of open contracts are equal, and open positions are only the sum of buyers and sellers. If both the buyer and the seller are new positions, two contracts will be added; If one party opens the position and the other party closes the position, the position remains unchanged; If the buyers and sellers close their positions, the positions will be reduced by 2 contracts. When the next opening quantity is equal to the closing quantity, the positions held will remain unchanged. Since the open contract refers to the number of contracts that have not been hedged and settled during the period from the beginning of the transaction to the end of the open contract, the more open contracts, the greater the sum of closed contracts and physical delivery before the contract expires, and the greater the transaction volume. Therefore, the analysis of the change of positions can infer the flow of funds in the futures market. The increase in positions indicates that funds flow into the futures market; On the contrary, it means that funds are flowing out of the futures market.
