成交量是一種供需的表現(xiàn)，指一個(gè)時(shí)間單位內(nèi)對(duì)某項(xiàng)交易成交的數(shù)量。當(dāng)供不應(yīng)求時(shí)，人潮洶涌，都要買(mǎi)進(jìn)，成交量自然放大；反之，供過(guò)于求，市場(chǎng)冷清無(wú)人，買(mǎi)氣稀少，成交量勢(shì)必萎縮。而將人潮加以數(shù)值化，便是成交量。廣義的成交量包括成交股數(shù)、成交金額、換手率；狹義的也是最常用的是僅指成交股數(shù)。
成交量指當(dāng)天成交的股票總手?jǐn)?shù)（1手=100股）。VOL顯示是1M在國(guó)際通行的說(shuō)法是1K=1000、1M=100萬(wàn)、1B=10億。10^3、10^6、10^9
需要注意的是，通常人們說(shuō)的大盤(pán)成交量指的是成交金額。說(shuō)明市場(chǎng)的活躍度和資金規(guī)模。成交量與成交金額用下列公式表示：成交數(shù)量（成交量）×成交均價(jià)=成交金額（成交額）
