什麼是EMA和MA?

What are Moving averages?

Moving averages are among the 什麼是EMA和MA? most widely used and efficient indicators for technical analysis. Traders of all levels determine long term trends using this tool. We’ll cover how to define a trend, how to implement this indicator for support and resistance levels, and how to use it as trade 什麼是EMA和MA? entry and exit signal.

What are Moving Averages?

Moving averages (什麼是EMA和MA? MA) indicate the average trend within the chosen period, smooth out price action and filter out the noise. They are formed using the average closing price over a set number of periods. For 什麼是EMA和MA? example, a ten-day simple moving average is a total of the closing prices during a period of ten days divided by ten.什麼是EMA和MA?

The most commonly used moving averages are:

Simple Moving Average (SMA), 什麼是EMA和MA? which indicates the average movement of price during a particular time period;

Exponential Moving Average (EMA), which is similar to SMA, but applies a greater weight to more recent prices.

Adding Moving Averages 什麼是EMA和MA? to your chart in MetaTrader 4

You can add moving averages to your chart simply by clicking the ‘indicators list’ icon in the 什麼是EMA和MA? toolbar and selecting ‘moving average’. From there you can choose the period and the type of MA you want to work with. If you’re using multiple moving averages you can change the color in order to identify them easily.

Simple Moving Averages vs. Exponential Moving Averages

SMA are slower than EMA in responding to price action. Consequently, they indicate trends or trend reversals more slowly, but are less prone to false signals. EMA are better at catching trends early, though they will give you more false signals during consolidation 什麼是EMA和MA? 什麼是EMA和MA? periods.

Using several types of moving averages will give you a 什麼是EMA和MA? broader outlook. For instance, a trader might choose longer period SMA 什麼是EMA和MA? to help understand the broader trend, and shorter period EMA for entry signals.

SMA may better identify support and resistance levels since they reflect a balanced average of prices over a set time period.

How to determine a trend using MA?

When a price action remains above a moving average, it signals that the price 什麼是EMA和MA? 什麼是EMA和MA? has an uptrend. Conversely, if a price action stays below the 什麼是EMA和MA? MA it indicates a downtrend.

Using several MA simultaneously can be beneficial in determining a trend. Make sure the MA lines are set in the correct order (from fastest to slowest in an uptrend, 什麼是EMA和MA? 什麼是EMA和MA? from slowest to fastest in a downtrend) to confirm that you are in a strong uptrend or downtrend.

Moving Average Crossovers

MA crossovers help to determine when a new trend starts and when an existing one is about to reverse.

Upward momentum is confirmed with a bullish crossover, when short-term MA crosse above longer-term MA. This can be called a ‘Golden Cross’. Downward momentum is confirmed with a bearish crossover, when short-term MA cross below longer-term MA, also known as a ‘Death Cross’. Short term MA can be used for intraday trading, for instance, EMA with 5 and 10 periods.

Longer-term traders might prefer SMA crossovers with 50 and 200 periods.

On one hand, MA crossovers tend to work well in trending markets, while on the other, they can be worthless in sideways or consolidating markets.

Moving Averages as Dynamic Support and Resistance Levels

MA can also be used as support in an uptrend and resistance 什麼是EMA和MA? in a downtrend. For example, a short-term uptrend might find support near the 21-day EMA, while a long-term uptrend might find support 什麼是EMA和MA? near the 200-day SMA.

50 and 200-period SMA are mostly followed on the daily chart and often represent key support and resistance levels. Keep in mind that the levels are not exact, and MA more often represent areas of support and resistance. Levels are 什麼是EMA和MA? also dynamic, as they are constantly changing based on recent price 什麼是EMA和MA? action.

MA is a multi-faceted indicator that can help you to define a trend, support and resistance. It can also show when a new trend starts and when a trend is about to 什麼是EMA和MA? 什麼是EMA和MA? reverse. Set different periods of MA to determine what works best 什麼是EMA和MA? for your trading strategy.

什麼是EMA和MA?

有四种不同类型的移动平均线:简单移动平均线 (也被称为算术), 指数移动平均线, 平滑移动平均线 以及 线形权数移动平均线 。我们可以为任何一套顺序排列的数据来进行移动平均线的计算,包括开盘价和收盘价,最高价和最低价,交易量和任何其他指标。同时有两条移动平均线被使用的情况比较普遍。

  • 简单移动平均线 (SMA)
  • 指数移动平均线 (EMA)
  • 平滑移动平均线 (SMMA)
  • 线形权数移动平均线 (LWMA)

移动均线

简单移动平均线 (SMA) #

SMA = SUM (CLOSE (i), N) / N

SUM ― N周期求和;
CLOSE (i) ― 收盘价;
N ― 计算中使用到的周期。

指数移动平均线 (EMA) #

EMA = (什麼是EMA和MA? CLOSE (i) * P) + (EMA (i - 1) * (1 什麼是EMA和MA? - P))

CLOSE (i) ― 当前收盘价;
EMA (i - 1) ― 前一周期移动平均线值;
P ― 使用价格数值的百分比。

平滑移动平均线 (SMMA) #

SUM1 = SUM (CLOSE (i), N)

SMMA (i) = (SMMA1*(N-1) + CLOSE (i)) / N

PREVSUM = SMMA (i - 1) * N

SMMA (i) = (PREVSUM - SMMA (i - 1) + CLOSE (i)) / N

SUM ― sum;
SUM1 ― total sum of closing prices for N periods; it is counted 什麼是EMA和MA? from the previous bar;
PREVSUM ― smoothed sum of the previous bar;
SMMA (i-1) ― smoothed moving average of the previous bar;
SMMA (i) ― smoothed moving average of the current bar (except 什麼是EMA和MA? for the first one);
CLOSE (i) ― current close price;
N 什麼是EMA和MA? ― smoothing period.

SMMA (i) = (SMMA (i - 1) * (N - 1) + CLOSE (i)) / N

线形权数移动平均线 (LWMA) #

LWMA = SUM (CLOSE (i) * i, N) / SUM (i, N)

SUM 什麼是EMA和MA? ― N周期求和;
CLOSE(i) ― 收盘价;
SUM (i, N) ― 权数系数总和;
N ― 平滑周期。

1、EMA与PMA 基本没有什么区别的. EXPMA(指数平均数) 一、用途: 该指标以交叉为主要讯号.该指标可以随股价的快速移动,立即调整方向,有效地解决讯号落后的问题,但该指标在盘整行情中不适用.

2、MACD是平滑异同移动平均线,主要是利用长短期的二条平滑平均线,计算两者之间的差离值,作为研判行情买卖之依据. 算法: DIFF线 收盘价短期、长期指数平滑移动

3、EMA(Exponential Moving Average),什麼是EMA和MA? 什麼是EMA和MA? 指数平均数指标.也叫EXPMA指标,它也是一种趋向类指标,指数平均数指标是以指数式递减加权的移动平均. 求X的N日指数平滑移动平均,在股

5、EMA(P1,P2) 中文名: 平滑移动平均 英文名: EMA 描述:求P1的P2日平滑移动平均 算法:P=EMA(P1,P2), P=[2*P1+(P2-1)*P']/(P2+1),P'=上周期P

6、EMA、SMA、DMA分别是指数平滑移动平均、移动平均、动态移动平均. 一、EMA(X,N),求X的N日指数平滑移动平均. 算法:若Y=EMA(X,N) 则Y=[2*X+(N-1)*Y']/(N+1), 其中Y'表示上一周期Y值. 二、SMA(X,N,M),求X的N日移动平均,M为权重. 算法:若Y=SMA(X,N,M) 则 Y=(M*X+(N-M)*Y')/N, 其中Y'表示上一周期Y值,N必须大于M. 三、DMA(X,A),求X的动态移动平均. 算法:若Y=DMA(X,A) 则 Y=A*X+(1-A)*Y', 其中Y'表示上一周期Y值,A

7、EMA的意思是“Exponential Moving Average”,中文可以翻译为“指数移动平均线”,又称“平滑移动平均线”公式到处都能找到,这里就不赘述了. EMA实际上也是一种“加权移动平均线”,并且对距离当前较近的K线赋予了较大的权重,公式没有必要特别去记,只要记得其特性就可以了. 从技术指标的“自我实现”效应来说,如果不是以观察平均线的“交叉”为目的,那么完全没有必要采用复杂的均线,最简单的SMA简单移动平均线就可以
