At this time, the total position in the market is 20 lots. If one more person wants to sell 10 lots, the first two people don't hold orders, so the transaction can't be reached and the transaction can't be done. If the first person wants to buy a seat, he can make a deal with the third person. Open position is the number of open positions, that is, the number of futures contracts that have not been hedged for physical delivery after buying or selling.
Whether investors are long or short in the futures market is a personal judgment on the futures market. Many traders participate in the fluctuation of futures prices and the formation of trading prices. The change of long and short power lies in the number of investors who are long or short. If only in the sense of fluctuation, long and short are not unequal. The real inequality lies in the difference between investors and contract enterprises.
The advantages of spot enterprises participating in futures are very obvious. When the price in the futures market is lower than the spot price and it is expected to rise in the future, enterprises will buy futures contracts in the futures market until the contract expires for physical delivery. Most of the participants in the market are non-spot enterprises, so it is naturally impossible to deliver in kind, and they can only choose to buy and close their positions. The futures market is bullish and prices skyrocket. On the other hand, the futures price is higher than the spot price to sell short positions in the futures market. The purpose of investors' participation in the futures market is not to buy physical objects, so naturally they can't be delivered due, and they can only close their positions and sell them. If the short-selling power of the market increases, the price will plummet. These two situations are the inequality between short positions and long positions in the futures market.
