昨天讲了关于玩OKEX合约的一些入门知识，今天一鼓作气，把有关K线的一些关键点再详细聊一聊。
Some introductions to the OKEX contract were made yesterday, and some key points about the Kline are discussed in more detail today.
一、上下影线
i, up and down
我们在听分析师分析币价的时候，还会经常提到“上影线”“下影线”之类的词。
When we listen to analysts analysing currency prices, we often refer to words such as “upline” and “downline” and so on.
K线将买卖双方力量的增减与转变过程及实战结果用图形表示出来。
The K Line graphically describes the growth and decrease in the power of both buyers and sellers and the transformation process and the actual results of the battle.
①当收盘价高于开盘价时，称为“阳线”，绿色的方框表示。
1 When the closing price is higher than the opening price, it is referred to as the “positive line” and the green box is indicated.
②当收盘价低于开盘价时，称为“阴线”，红色的方框表示。
2 When the closing price is lower than the opening price, it is referred to as the “circular line” and the red box is indicated.
影线就是一根K线中的虚线，它代表了当日最高和最低价格与收盘价格的差。上下影线是指上影线和下影线，一般情况上影线长，表示阻力大；下影线长表示支撑力度大。
The line is a dotted line in the Kline, which represents the difference between the highest and lowest price on the day and the closing price. The upper and lower line is the upper and lower line, which is usually the longer line, indicating a lot of resistance; the lower line indicates a lot of support.
二、支撑位和压力位
II, support and pressure
支撑位、压力位可以帮助我们更好的判断后续行情走势，也可以作为买入或卖出的参考依据，特别是对于短线用户，支撑位和压力位几乎是必学的功课之一。
The support position, the pressure position, can help us better judge subsequent trends and can also serve as a reference for buying or selling, especially for short-line users, where the support position and the pressure position are almost one of the required lessons.
支撑位顾名思义：当币价跌到某一个位置的时候会形一种支撑，像是在这个位置有什么东西在阻止币价下跌；同样，压力位也就是说：当币价涨到某一个位置的时候就很难突破，好像是有什么东西在压着它，阻止它继续上涨一样。
By name: When a currency falls to a position, it forms a support, as if there is something in that position that prevents it from falling; similarly, the pressure position means that when a currency rises to a position, it is difficult to break, as if something was pressuring it to stop it from rising.
支撑位和压力位并不是一成不变的，相互之间可能会进行角色转变，如：当支撑位被有效跌破后可能会变成之后的压力位，当压力位被有效突破后也可能变成新的支撑位。
The supporting position and the pressure position are not static, and there may be role shifts between them, for example, when the support position is effectively broken, it may become a post-pressure position, and when the pressure position is effectively broken, it may become a new support position.
每个人判断支撑位和压力位的方式不同，有人把三个根以上同等收盘价的K线就称为支撑位或压力位，有人把均线所在的位置称为压力位或者支撑位（注意：是很大可能，不是100%）如果币价处于这些均线下方，均线就是压力位，如果币价处于均线上方那么均线就是支撑位。
Each person will judge the support and pressure position differently, with Klines with more than three equally priced lines being referred to as the support position or the pressure position, or the position where the mean line is located as the pressure position or the support position (note: very likely, not 100 per cent) if the currency is below those lines, the mean line is the pressure position, and the mean price is the support position if it is above the mean line.
三、布林线（boll）
iii, , ,
布林线（Boll）可以简单理解成由三条指标线形成的区间，其中上下两条线可以分别看成是币价的压力线和支撑线，而在两条线之间还有一条币价平均线。
The Booll Line can be understood simply as a zone formed by three indicator lines, the top and bottom of which can be seen as pressure lines and support lines in currency terms, respectively, while there is an average line in currency value between the two lines.
上图是我通过OKEX页面-更多-选中【boll】，截取的一部分布林线。一般来说，币价会运行在压力线和支撑线所形成的通道中。简而言之，币价会在压力线和支撑线之间涨幅。
The figure above is that I intercept part of the boolean line through OKEX page - more - [boll]. Generally, the currency runs through the pressure line and the line of support. In short, the price increases between the pressure line and the line of support.
布林线（Boll）指标是币圈技术分析的常用工具之一，通过计算币价的“标准差”，再求币价的“信赖区间”。利用布林线指标选币，主要是观察布林线指标开口的大小，对那些开口逐渐变小的数字币就要多加留意了。因为布林线指标开口逐渐变小代表币价的涨跌幅度逐渐变小，多空双方力量趋于一致，币价将会选择方向突破，而且开口越小，币价突破的力度就越大。
The Booll indicator is one of the commonly used tools for the technical analysis of currency circles. By calculating the “standard deviation” in currency prices, the “trust zone” in which currency prices are sought. Using the Boolin indicator, which is primarily to observe the size of the opening of the boolean indicator, much more attention is paid to those openings that are becoming smaller. Because the opening of the Boolin Line indicator is gradually becoming smaller in terms of the ups and downs of currency prices, there is a convergence of forces, currency prices are about to break in the direction, and the opening is smaller, and the price is about to break out.
那么到底开口多小才算小，这里可引入极限宽指标（width），即表示布林线指标开口大小的指标。有的软件没有这个指标，可以通过以下方法计算：width＝（布林上限值－布林下限值）／布林币价平均值。一般来说极限宽指标小于10的数字币随时有可能发生突破。但是，极限宽指标值的临界点会随个币不同而改变，所以最好观察该币一年来的极限宽指标走势以确定极限宽指标值的临界点。
So how small are the openings, where the width indicators are introduced, that is, indicators of the opening of the boolean line indicators. Some software does not have this indicator, which can be calculated by means of an average of width=(Burling cap-Burling limit)/Burling currency prices. Generally speaking, there is a potential for a breakthrough in digital currencies with less than 10. However, the threshold point of the limit width indicator will change with a currency, so it is better to observe that currency’s limit-broadness indicator movement over the course of the year to determine the threshold of the limit-broadness indicator value.
四、MACD
iv, , MACD
在OKEXK线页面交易量下方，还有一个显示为MACD（12，26，9）的动态图。
There is also a dynamic map showing MACD (12,26,9) below the transaction volume on the OKEXK line page.
MACD是一个非常实用的指标，它能很明确的反应出多空双方各自的力量强弱，对于预测行情走势有很大的参考性；
(a) MACD is a very practical indicator of how clearly it responds to the strength and weakness of each of the two sides and is highly indicative of predictive trends;
MACD的默认参数设置是（12，26，9），很多人问我，这里面的数值代表什么，12为两周，26为一个月，9为一周半。
The default parameters for MACD are (12,26,9) and many ask me what the values are, 12 weeks, 26 months, 9 weeks and a half.
MACD由白线（DIF）、黄线（DEA）、红色能量柱、绿色能量柱四个方面构成，红色能力柱代表卖出力量，绿色能量柱代表买入力量，也就是常说的多方和空方。绿柱越高表示多方越强，红柱越高代表卖出力量更强。
The MACD consists of the white line (DIF), the yellow line (DEA), the red energy column, the green energy column, which is selling power, and the green energy column, which is buying power, which is often said to be multiple and empty. The higher the green column is, the higher it is, the higher it is selling power.
以零轴为中轴，区分走势强弱，0以上为强势、0以下为弱势，零轴我在下图中以蓝色线画了出来。MACD指标有金叉和死叉：白线上穿黄线为金叉（买入信号），白线下穿黄线为死叉（卖出信号）。对于死叉来说，位置越高，下跌趋势概率越大，同理，对于金叉，位置越低，上行概率越大。
The middle axis is zero-axis, where the distinction is strong and weak, with more than zero being weak and less than zero being vulnerable, and the zero-axis is drawn in the next figure with blue lines. The MACD indicators are gold fork and dead fork: yellow fork on the white line (buying signals) and yellow fork under the white line (sale signals). For the dead fork, the higher the position, the greater the probability of declining trends, the same for the gold fork, the lower the position, the greater the probability of going up.
MACD线，常用于分析买入、卖出时机。当MACD线翻绿，即由负变正时为买入时机；当MACD线翻红，即由正变负时为卖出时机。
MACD lines, often used to analyse when buying and selling. When the MACD lines turn green, i.e. when negative positive, when buying; when the MACD lines turn red, when positive or negative.
顶背离现象：由于现在的操盘手技术都比较高，找个标准的顶背离不是随便就有，就以下图为例吧，虽然不太明显，但是提现出的理论就是这样的。顶背离就是前期出现大涨后，MACD出现回调，但是币价却不断创新高。如图所示，顶部出现阳线上升趋势，对应底部的能量柱却在水平线以下，形成相反走势。白线DIF和黄线DEA形成死叉，这就是顶背离现象，如果不能顺利出逃的话，后果不堪设想。
Apparent deviations: because of the current high level of mastering techniques, it is not random to find a standard top deviation, for example, the following illustrations, although less obvious, are the theory that emerges. The top deviation is the rewinding of the MACD after the surge in the previous period, but the price of the currency is constantly rising. As the figure shows, there is an upward trend at the top, and the energy column at the bottom is below the horizontal line, forming the opposite trend. The white-line DIF and the yellow-line DAA form the dead end, which is the worst deviation, and the consequences if not the escape is not successful.
和其它所有技术指标一样，MACD指标偶尔也有预测错误的时候，所以还是那句话，不要轻信一个技术指标，我们在进行实际操作时要根据市场实际情况和综合多个技术指标来进行分析。
Like all other technical indicators, MACD indicators occasionally have faulty predictions, so let's just say that there is no need to believe in a technical indicator, and that we do so in a hands-on way, with analysis based on market realities and a combination of multiple technical indicators.
