先谢谢啦。 要完整地做好一件力所能及的事的确是需要毅力和持之以恒的愚公移山的近乎偏执的一般人不屑于一做的就是1+1的简单重复琐事的婆婆劲，谁这样做了谁就成功了。 以下是近日找到的不可多得的好资源，供参考。 http://www.inworkshop.com/cgi-bin/leoboard.cgi

我在实际使用中也碰到这个问题，现在理解了一点：PointValue是指变动每个大点对应的合约损益金额(以美元为单位)。 比方说，欧兑美元汇率为1.2200，那么一个大点是指小数点前的整数个位。如果PointValue是1，也就是每一大点运动对应1美元，那么在测试系统的时候，系统就默认欧元只有变动到2.2200才会获得1美元的利润。这显然是不合适的，于是设为10000，那么每一小点变动代表1美元，就可以代表一个MINI帐户的情况了。但对于标准帐户，PointValue就需要设为100000，这样每一点变动就对应10美元出入。 至于Price Scale的定义，是指每一大点细分成多少份，对于欧兑美元来说就是1/10000，有段帮助，抄在下面。 Price Scale The fractional or decimal units in which prices are quoted by the exchange. For example, stocks on the NYSE are usually quoted in 1/8ths or 1/16ths, whereas OTC stocks are quoted in 1/64ths or 1/32nds. This field works in conjunction with the Minimum Movement and Big Point Value fields to provide an accurate representation of the value of point and fractional point moves of a symbol. For example, an S&P 500 futures' price scale is 1/100, its Minimum Movement is 10, and its Big Point Value is 250. This means that a contract's minimum tradable increment is 10/100 (or 1/10th), and when it moves 1/10th of a point, this represents a 25 dollar change ($250 divided by 10). Omega Research sets the Price Scale for all stocks to 1/1000 for accuracy purposes, and the Minimum Movement to 125, which equals 1/8, and all options to 1/16, with a Minimum Movement of 1, which equals 1/16. { ** © 1987,1999 Omega Research, Inc. ** }
