Bollinger bands breakout Indicator For MT5
Bollinger bands breakout Indicator For MT5的Bollinger bands breakout Indicator For MT5基于一个非常简单的想法。首先，借助简单的移动平均值计算以及标准偏差来创建波段。密切注意价格图表，当价格下降时，您会注意到上下带上的小标记。
当价格收于布林带上方时，市场即告完成。但是，交易者应根据市场波动谨慎选择时间范围，因为很大程度上取决于时间波动。例如，如果波动性较高，则必须依赖较大的时间范围，例如D1或每周。
相反，当波动停止时，交易者需要查看较小的时间范围数据。但是，时间范围较小的用户应该依赖价格行为信号。除非他们这样做，否则它们将处理过多的错误信号。当重大突破发生在此类重大财务事件上时，请始终注意主要新闻数据。
