I have been engaged in commodity trading for many years, but this is the first time I heard about the entry price, and I feel really ignorant. I understand whether it is the first guidance price when a certain commodity variety contract is launched. But I would like to remind you that the general market will have introductory materials, and there may be definitions or rules for trading terms and settlement terms, which can provide reference for understanding.

Stop-profit price and stop-loss price: These are terms applied to futures. In external trading, they are called STOP prices, which are the price positions at which profits or losses are stopped. In futures and external trading, you can set this Trading instructions are used to timely close transactions when no one is watching or when prices fluctuate violently, so as to avoid reduced profits or wider losses. However, in the domestic commodity trading market that I currently trade, I have not seen such trading order rules. Usually, a price is preset in the investor's mind, and the transaction is completed when the price fluctuates to that price.

Position: the amount of the commodity held by the investor.
