noun
medium price; average price
Used in financial and trading contexts to refer to a middle or average price, such as the midpoint between bid and ask prices.
今日のドル円の中値は110円50銭です。
Today's medium price for the dollar-yen is 110.50 yen.
中値で取引が成立した。

Compound of 中 (なか, 'middle') and 値 (ね, 'price'). The kanji 仲 is sometimes used as a variant, likely due to its similar meaning of 'relationship' or 'middleman', but 中 is the standard form.
