In futures trading, "offer" and "bid" are two key terms, which respectively represent the quotation behavior of buyers and sellers. Offer, that is, quotation, comes from the seller's initiative to provide the buyer with the details of the goods, which may be a response to the buyer's inquiry. Quotation usually contains important information such as commodity name, specification, quantity, packaging requirements, price, payment method and delivery time, and it is the way for the seller to show the trading terms to the buyer.

on the contrary, "bid", or bid, is the highest price that the buyer is willing to pay, which reflects the buyer's willingness to buy. In the futures market, the ask price is usually higher than the bid price, and the quotations of buyers and sellers can be easily distinguished by the price difference. In the transaction process, ask price represents the seller's bid, while bid price is the buyer's offer.

It is worth mentioning that futures traders usually choose the most active month, because the buyers and sellers of these contracts are more active, the trading volume is large and the trading is smoother. With the passage of time, forward contracts will gradually become short-term contracts until the delivery date. When the delivery date is approaching, trading activities will be significantly reduced due to time constraints and changes in margin rules. Generally, it is not recommended to delay the contract until the delivery date.

finally, the activity of futures contracts varies from commodity to commodity, with some trading frequently and others relatively deserted. An active contract means that it is easy for buyers and sellers to find counterparties, while a light contract may encounter difficulties in trading and the price fluctuation may be small. These factors have an important influence on trading strategy and risk management in the futures market.
