    Default 合约现货外汇交易(按金交易)

    合约现货外汇交易,又称外汇保证金交易、按金交易、虚盘交易,指投资者和专业从事外汇买卖的金融公司(银行、交易商或经纪商),签定委托买卖外汇的合同,缴付一定比率(一般不超过10%)的交易保证金,便可按一定融资倍数买卖10万、几十万甚至上百万美元的外汇。因此,这种合约形式的买卖只是对某种外汇的某个价格作出书面或口头的承诺,然后等待价格出现上升或下跌时,再作买卖的结算,从变化的价差中获取利润,当然也承担了亏损的风险。由于这种投资所需的资金可多可少,所以,近年来吸引了许多投资者的参与。

    外汇投资以合约形式出现,主要的优点在于节省投资金额。以合约形式买卖外汇,投资额一般不高于合约金额的5%,而得到的利润或付出的亏损却是按整个合约的金额计算的。外汇合约的金额是根据外币的种类来确定的,具体来说,每一个合约的金额分别是12,500,000日元、62,500英镑、125,000欧元、125,000瑞士法郎,每张合约的价值约为10万美元。每种货币的每个合约的金额是不能根据投资者的要求改变的。投资者可以根据自己定金或保证金的多少,买卖几个或几十个合约。一般情况下,投资者利用1千美元的保证金就可以买卖一个合约,当外币上升或下降,投资者的盈利与亏损是按合约的金额即10万美元来计算的。有人认为以合约形式买卖外汇比实买实卖的风险要大,但我们仔细地把两者加以比较就不难看出差别所在,请详见下表。

    任何交易都是有风险的,关键是自己控制风险。
