这个Expert Advisor是基于3条移动平均线指标，移动平均线交叉基于下列思想:快速、中速、慢速3条移动平均线交叉时，作为开仓和关仓的信号，其中三线交叉包含了三线交叉于一个点的特例。

当FastMA(MA1) 向上穿越middleMA(MA2)与middleMA(MA2)向上穿越slowMA(MA3)时建立多单.

当FastMA(MA1) 向下穿越middleMA(MA2)与middleMA(MA2)向下穿越slowMA(MA3)时建立空单；

当FastMA(MA1) 向下穿越middleMA(MA2)，关闭多单，当FastMA(MA1) 向上穿越middleMA(MA2)，关闭空单。

这个专家使用了资金管理，传统的止损、止盈、追踪止损。每次交易只有一个订单，这确保交易的最大安全。
