    Default 布林带-BOLL (Bollinger Band

    布林带由布林格 (Bollinger) 发明,也叫布林通道,是各种投资市场广泛运用的路径分析指标。一般价格的波动是在一定的区间内的,区间的宽度代表价格的变动幅度,越宽表示价格变动幅度越大,越窄表示价格变动幅度越小。布林带由支撑线(LOWER)、阻力线(UPER) 和中线(MID) 三者组成,当价格突破阻力线(或支撑线)时,表示卖出(或买入)时机。在布林格发明布林带之前,类似的路径分析指标已经在金融市场中使用了,但后来布林格将这种方法加以改进并系统化。布林格本人最重要的贡献可以说并不是其发明的布林带指标,而是他在使用布林带指标时着重强调的相对高低概念,并在分析时贯彻了这一思想。虽然此前已经有一些投资者意识到高低的位置都是相对的,但很少有人笃信并认真实践这一思想

    计算公式: MID = 收盘价的 n 个周期简单移动平均值

    TMP2 = 收盘价在 m 个周期内的标准差
    UPER = MID + PTMP2
    LOWER = MID - PTMP2 (注:P为变量
    交易是1 件慎重的事情~~~

    感觉在盘整行情使用布林好点,遇上突发,很难入手

    Boll线在短线中还是很管用的
