Trading foreign exchange on margin carries a high level of risk, and may not be suitable for all investors. Before deciding to trade foreign exchange you should carefully consider your investment objectives, level of experience, and risk appetite. You could sustain a loss of some or all of your initial investment and should not invest money that you cannot afford to lose.

Auction 競價投標定義

交易中,競價投標(競價市場)指在開盤前,收盤後和盤中波動競價期間定義股票價格從而建立或穩定交易委託賬本。競價允許交易者直接在交易所中直接下市價單或止損單。

 

交易所中任一特定股票的價格區間代表了買入者願意支付的最高價格,以及賣出者願意接受的最低價格。因為市場中有多個買入者和賣出者進行競爭,因此存在多個買入和賣出價。

 

競價中,為滿足最大化交易量,並且最小化未匹配訂單造成的過剩,所以流動性高度集中。

 

競價過程中,可直接在市場中下達、修改或取消訂單。然而,競價過程中無自動交易。當新訂單創建、修改或刪除時,指導性競價價格和未匹配交易量將更新:結果導致新的競價價格和規模的產生。

競價示例

力拓股票在澳大利亞證券交易所(ASX)進行交易。五位購買者分別出價每股$44.9, $44.6, $44.2 和 $43.9買入。同時有五位賣出者,分別出價$45.7, $45.3, $45.0 和$44.9。該股以$44.9交易。如果有賣出者願以$44.6賣出,則該價格將成為成交價。
