Small retail transactions can be compared. Do short-term within the band, not ultra-short-term within the day, just match the price.

The entrusted price is mainly for those big funds, which is more practical, because big funds will cause the market to fluctuate.

Take the simplest example, just like stocks. For example, Bill Gates has assets of $50 billion at the current share price of Microsoft 100, but these are only book figures. If he really wants to sell his stock to get cash, if the huge stock he holds is sold at the price of his opponent, it will directly lead to a sharp drop in the selling price. Maybe he can only sell his stock at an average price of $80 (even only $50) in the end.
