In futures trading, if one party wants to buy, it must correspond to the other party's desire to sell. Suppose A wants to buy 10 soybean contract, and B only wants to sell 10 soybean contract, then they just have a deal. When two positions are opened at the same time, and the variety and quantity of trading contracts are the same, it is called double opening. Double opening means that two positions are opened at the same time, so add positions.
Multi-level refers to: long selling and liquidation, which means that the position decreases, but the absolute value of the position increase is less than the current quantity, which is active selling.
Empty flat: short sellers take the initiative to buy and close positions.
Short positions: short selling and opening positions.
Extended data:
Short position refers to lightening the position, but the absolute value of lightening the position is less than the current quantity, which belongs to active buying. For example, suppose three people are counterparties, in which A has five long positions, B has five short positions and C has no positions; If Party A wants to close the position, it will sell 3 positions, and if Party C thinks that the market will fall, it will sell 2 positions. At this time, Party B will also close the position.
Then use the current price (selling price) to hang out 5 lots to buy positions, and the disk will show: empty (short position), spot transaction 10 lots, position difference -6. If it is a long position, it is to take B as the active position, and A can then close the position.
