Profit-taking (profit-taking or arbitrage), also known as technical correction, also known as technical adjustment, refers to a trading behavior in which the holder of a stock or futures contract or option contract actively changes his position after the market value changes and a favorable price appears, so that the book profit can be converted into actual profit.

Profit-taking refers to a technical figure of commodities (products, stocks, etc.). In a short period of time, there is a certain profit space, and profitable investors sell goods, causing commodity prices to fall.
