长城科技(603897)K线图分析： Ｋ线图最早是日本德川幕府时代大阪的米商用来记录当时一天、一周或一月中米价涨跌行情的图示法,后被引入股市。Ｋ线图有直观、立体感强、携带信息量大的特点,蕴涵着丰富的东方哲学思想,能充分显示股价趋势的强弱、买卖双方力量平衡的变化,预测后市走向较准确,是各类传播媒介、电脑实时分析系统应用较多的技术分析手段。其记录方法如下：（如图所示）
1、日K线是根据股价(指数)一天的走势中形成的四个价位即：开盘价,收盘价,最高价,最低价绘制而成的。 收盘价高于开盘价时,则开盘价在下收盘价在上,二者之间的长方柱用红色或空心绘出,称之为阳线；其上影线的最高点为最高价,下影线的最低点为最低价。 收盘价低于开盘价时,则开盘价在上收盘价在下,二者之间的长方柱用黑色或实心绘出,称之为阴线,其上影线的最高点为最高价,下影线的最低点为最低价。
2、根据K线的计算周期可将其分为日K线,周K线,月K线,年K线。 周K线是指以周一的开盘价,周五的收盘价,全周最高价和全周最低价来画的K线图。月K线则以一个月的第一个交易日的开盘价,最后一个交易日的收盘价和全月最高价与全月最低价来画的K线图,同理可以推得年K线定义。周K线,月K线常用于研判中期行情。对于短线操作者来说,众多分析软件提供的5分钟K线、15分钟K线、30分钟K线和60分钟K线也具有重要的参考价值。
3、根据开盘价与收盘价的波动范围,可将Ｋ线分为极阴、极阳,小阴、小阳,中阴中阳和大阴、大阳等线型。它们一般的波动范围（如图所示）。
极阴线和极阳线的波动范围在0.5%左右； 小阴线和小阳线的波动范围一般在0.6--1.5%； 中阴线和中阳线的波动范围一般在1.6-3.5%； 大阴线和大阳线的波动范围在3.6%以上。
