什么是移动平均线指标？

简称sma或者ma，也就是俗称的"均线"，是最最古老的技术分析指标了。

# 加权移动平均线（Weigted Moving Average）

简称wma，这个相当于是移动平均线的改进。前面说到简单移动平均线是每一天的权重都一样，这样拉低了最近几天暴涨暴跌的影响。加权移动平均线对此作了改进，把日期较近的收盘价的权重提高了。

比如最近6天股票的收盘价序列：[32.8, 25.8, 48.40, 34.50, 25.3, 45.0]
第1天在最左边，第6天在最右边，那么第1天的权重最小，为1，第6天的权重最大，为6，总的权重是6+5+4+3+2+1=21

所以加权移动平均线的计算方式就是：
wma(6)=(6 * 45.0+5 * 25.3+4 * 34.5+3 * 48.4+2 * 25.8+1 * 32.8)/21=764.1/21.0=36.39

# 指数移动平均线（Exponential Moving Average）

简称ema，先定义EMA(X，N)，它表示求X的N日指数平滑移动均匀。

那么指数移动平均线的公式就是：
EMA[n]= a * Pn + (1-a) * EMA[n-1]

  • Pn：表示第n日的收盘价
  • a：权重值。a的取值可以有下面几种:
    • 2/(N+1), N为上面的周期天数
    • 1/(1+decay)，decay为衰减系数

    接下来看看EMA的例子就知道它的思想了：
    第1天， EMA(1)=p1
    第2天， EMA(2)=a*p2+ (1-a)*p1
    第3天， EMA(3)=a*p3+ (1-a)*(a*p2+(1-a)*p1)= a*p3+ a(1-a)p2 + (1-a)^2*p1
    第4天， EMA(4)=. = a*p4+ a(1-a)p3 + a(1-a)^2*p2+a(1-a)^3*p1

    均线适用于跟踪趋势的发展. 可以提醒新趋势的开始或反转. 该指标不能预测市场的反应. 均线是滞后指标, 遵循市场移动并指出新趋势的出现或趋势的反转.

    外汇指标 FAQ

    什么是外汇指标?

    交易者使用外汇指标来预测市场的价格走势, 从而增加在外汇市场中赚钱的机会.外汇指标实际上考虑了特定交易工具的价格和数量, 以进行进一步的市场预测.

    什么是最佳技术指标?

    技术分析通常包含在各种交易策略中, 不能与技术指标分开考虑.一些指标很少使用, 而另一些指标对于许多交易者而言几乎是不可替代的.我们重点介绍了5种最受欢迎的技术分析指标：移动平均线（MA）, 指数移动平均线（EMA）, 随机震荡指标, 布林线, 移动平均收敛散度（MACD）.

    如何使用技术指标?

    交易策略通常需要多个技术分析指标以提高预测准确性.落后的技术指标显示了过去的趋势, 而领先指标则预测了未来的趋势.选择交易指标时, 还应考虑不同类型的图表工具, 例如交易量, 动量, 波动率和趋势指标.

    指标在外汇中是否起作用?

    指标有两种：落后和领先.滞后指标基于过去的走势和市场反转, 并且在市场趋势强劲时更为有效.领先指标试图预测未来的价格走势和反转, 它们通常在区间交易中使用, 并且由于它们会产生许多错误信号, 因此不适合趋势交易.

    什么是移动平均线指标？

    一.什么是移动平均线

    移动平均线，Moving Average，简称MA，原本的意思是移动平均，由于我们将其制作成线形，所以一般称之为移动平均线，简称均线。它是将某一段时间的收盘价之和除以该周期。 比如日线MA5指5天内的收盘价除以5。

    二.方法概述

    (1)基本分析（Fundamental Analysis ）：以企业价值作为主要研究对象，通过对决定企业内在价值和影响股票价格的宏观经济形势、行业发展前景、企业经营状况等进行详尽分析，以大概测算上市公司的长期投资价值和安全边际，并与当前的股票价格进行比较，形成相应的投资建议。基本分析认为股价波动轨迹不可能被准确预测，而只能在有足够安全边际的情况下“买入并长期持有”，在安全边际消失后卖出。

    What are Moving averages?

    Moving averages are among the 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 entry and exit signal.

    What are Moving Averages?

    Moving averages (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 example, a 什么是移动平均线指标？ ten-day simple moving average is a total of the closing prices during a period of ten days divided by ten.

    The most commonly used moving averages are:

    Simple Moving Average (SMA), 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 什么是移动平均线指标？ more recent prices.

    Adding Moving Averages to your chart in MetaTrader 4

    You can add moving averages to your chart simply by clicking the ‘indicators list’ 什么是移动平均线指标？ icon in the 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 什么是移动平均线指标？ are better at catching trends early, though they will give you more false signals during consolidation periods.

    Using several types of moving averages will give 什么是移动平均线指标？ you a broader outlook. For instance, a trader might choose longer period SMA 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 has an uptrend. Conversely, if a price action stays below the 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, from slowest to fastest 什么是移动平均线指标？ 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 什么是移动平均线指标？ 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 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 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 什么是移动平均线指标？ levels are not exact, and MA more often represent areas of support and resistance. Levels are also dynamic, as they are constantly changing based on recent price 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 reverse. Set different periods of MA to determine what works best for your trading strategy.
