涨跌有趋势，读懂价格语言；
买卖有信号，告别感觉交易。
一、什么是K线？
今天我们一起学习，技术分析中最基础的元素——K线。K线是当今最为普遍的价格标记法。
先来看一下，一天中价格在市场中是如何运行的。
在没有经过K线标记法处理时，某投资品的价格是这样的，无数的价格连在一起形成一条看起来毫无规律的曲线图。看起来有些乱是不是？
下面，我们做一下简单的技术分析处理，标记一下其中重要的数据：开盘价、收盘价、最高价、最低价。我们过滤掉其中繁乱的价格变化，将其绘制成折线图。如图所示，这样看起来是不是清晰很多？
二、什么是K线图？
可不可以，用更简单的表示它呢？当然可以，K线图了解一下。如图这样处理，将开盘价、收盘价、最低价、最高价，平移到一条垂直线上。开盘价与收盘价之间构成K线实体，我们用较粗线条表示，实体到最高价和最低价之间我们用细线条表示，分别构成上影线和下影线。
收盘价低于开盘价的，我们用红色标记实体，表示该时段价格下跌，通常称为阴线。收盘价高于开盘价的，我们用绿色标记实体，表示该时段价格上涨，通常称之为阳线。（当然部分市场会使用相反颜色标记K线涨跌。）
当我们把每一天的K线连在一起，就会出现我们常见的K线图样子。图中每一根红色或绿色的K线都代表一天的价格变化数据。一天的价格走势可以用一根K线表示，那么一分钟、一个小时、一星期呢？
根据统计价格变化的时间范围的不同，我们将K线分为不同的周期。这是多条一分钟K线连在一起的样子，这是多条“周K线”连在一起的样子。周期的划分非常灵活多样，几分钟、几小时、几天、几周或是几个月都可以。
K线，在投资市场分析中有什么作用？特定的K线形态或特定的K线组合出现后，大概率会发生特定的价格走势。因为价格包含一切市场行为，历史会惊人的相似。
后续我们再来分享，通过观察K线规律性排列，预判未来价格涨跌的方法。
