MACD指标是指数平滑异同平均线的简称，是由美国投资家查拉尔德·阿佩尔(Gerald Apple)根据双指数移动平均线发展而来的技术指标。MACD指标由两条指标线和一组柱线组成，如图所示。
The MACD indicator is a acronym of the same average for index smoothness and is a technical indicator developed by American investor Gerald Apple on the basis of the two-indicator moving mean line. The MACD indicator consists of two indicator lines and a cluster of columns, as shown in the figure.
MACD指标的基本构造
MACD指标中波动较快的曲线是DIF线，具体计算方法是12日EMA数值减去26日EMA数值。其中，EMA指标是一种类似于均线的技术指标，可以表示币价在一段时间内的平均价格。DIF线计算两条不同周期的EMA线之差，粉丝们可以将其理解为币价短期内的涨跌速度。
The more volatile curve in the MACD indicator is the DIF line, calculated by the 12-day EMA value minus the 26-day EMA value. Among these, the EMA indicator is a technical indicator similar to the mean line that indicates the average price of the currency over a period of time. The DIF line calculates the difference between the EMA line for two different cycles, which fans can interpret as the short-term rate of appreciation and decline.
MACD指标中波动较慢的曲线是DEA线，DEA线是DIFF线的平滑移动平均线。可以表示DIF线的涨跌趋势。如果说，DIF线是币价短期内涨跌速度的话，那么DEA线就是币价在长期内的涨跌速度。
The less volatile curve in the MACD indicator is the DAA line, which is the smooth moving average of the DIFF line. This can be shown as the upward and downward trend of the DIF line. If the DIF line is the rate of short-term appreciation and decline, the DEA line is the rate of long-term appreciation and decline.
MACD指标中红色和绿色的柱线是MACD柱线，其计算方法是DIF线与DEA线之差的2倍。MACD柱线是两条速度线之差，粉丝们可以将其理解为币价涨跌的加速度，或者是推动币价内在涨跌动能的强弱。
The red and green poles in the MACD indicators are two times the difference between the DIF and the DAA lines. The MACD column is the difference between the two velocity lines, which fans can interpret as an acceleration of currency price increases and falls, or as a boost to the internal strength of currency prices.
在这三个指标线中，DIFF线处于0轴上方时，说明币价短期处于上涨趋势中，曲线位置越高，短期内上涨的速度越快;处于0轴下方时，说明币价短期处于下跌趋势中，曲线位置越低，短期内下跌的速度越快。
The DIFF line is above the 0-axis, indicating that currency prices are on a short-term upward trend, that the higher the curve position, the faster the short-term increase; and below the 0-axis, that currency prices are on a short-term downward trend and that the lower the curve position, the faster the short-term decline.
DEA线处于0轴上方时，说明币价长期处于上涨趋势中，曲线位置越高，长期内上涨的速度越快;处于0轴下方时，说明币价长期处于下跌趋势中，曲线位置越低，长期内下跌的速度越快。
When the DEA line is above the 0-axis, it indicates that currency prices are in the upward trend over the long term, that the higher the curve position, the faster the increase over the long term, and that below the 0-axis, the lower the curve position, the faster the fall over the long term.
MACD柱线处于0轴上方时，显示为红色，说明有多方力量向上推动币价。此时币价的上涨速度会逐渐加快，或者下跌速度会逐渐减慢。柱线越长推动币价的力量就越强。处于0轴下方时，显示为绿色，说明有空方力量向下打压币价。此时币价的上涨速度会逐渐减慢，或者下跌速度会逐渐加快。柱线越长打压币价的力量就越强。
When the MACD pillar is above the 0-axis, it shows red, indicating that there is a multiplicity of forces pushing up the currency price. At this point, the price rises more rapidly, or the rate of decline slows down. The longer the column pushes the price, the stronger it is. At the bottom of the 0-axis, the greener it is, the less powerful it is, the lower it is, the lower it is, the lower it pushes down the price.
