It refers to a trading method that takes the futures price in a certain month as the pricing basis, and uses the futures price to increase or decrease the premium agreed by both parties through consultation to determine the price of spot goods bought and sold by both parties.

Spot price trading is essentially a pricing method of spot trading, and both parties do not need to participate in futures trading. Spot price is a pricing method of futures delivery, that is, for a certain kind of forward delivery commodity, the commodity price is not directly determined, and the futures price of a certain day in the major international futures exchanges is used as the base price of spot price, plus the agreed premium as the final settlement price. According to the division of power to determine the actual transaction price at a specific time, spot price transactions can be divided into buyer's outcry transactions and seller's outcry transactions. If the power to decide the trading time belongs to the buyer, it is called buyer's outcry trading, and if the power belongs to the seller, it is called seller's outcry trading. Point price is not a term in LME trading.
