The latest price is the latest transaction price. The market price refers to the price you buy or sell on your own initiative. For example, the latest price of glue is 30 thousand, buy a price of 29995, and sell a market price of 35 thousand. The market price means that you need to buy 30005 and sell it for only 29995. Anyway, market trading is active, and you have to lose money on the price to ensure the transaction.
