移动平均线
关键字：移动平均线
所谓移动平均线，就是对于一段时间内的价格进行平均，籍以推测该段时间内所有投资者的“平均成本”。一般而言，移动平均线也具有支撑与压力的性质。当多头时价格接近移动平均线，显示目前价位已接近所有投资者的布局成本，这时候低接的买盘就会进场承接，也对价格形成支撑；反之当价格下跌波段时，价格反弹至移动平均线附近，则可能出现解套卖压，价格因此再度往下滑落。
一般市场上最常用的指标是10日移动平均线。由于两个星期之中有十个交易日，正是短期趋势所对应的时间范围，对于一般投资者来说也是非常适合参考的时间长度，可供短期进出的参考依据。
买入法则：
1.均线从下降转为平缓或上升，价格同时向上突破均线，此时为买入信号。
2.价格虽跌破均线，但立刻回到均线之上并持续上涨，此时为买入信号。
3.价格由均线上方回落至均线附近止跌向上，此时为买入信号。
4.价格跌破均线之后出现暴跌，远离均线的价格出现反转，此时为买入信号。
卖出法则：
1.均线从上升转成平缓或下降，价格同时跌破均线，此时为卖出信号。
2.价格虽突破均线，但立刻回到均线之下并持续下跌，此时为卖出信号。
3.价格由均线上方上涨至均线附近受卖压而价格回落，此时为卖出信号。
4.价格突破均线之后出现暴涨，远离均线的价格出现反转，此时为卖出信号。
