Forex Trading with the MACD
ForexTrading with the MACDJune 26,2008 · Filed Under General, Guest Blogger  Afterreceiving many requests, I’ve contacted the team from DayTradeology to help explain how touse MACD AND Forex. Please let me know what you think of the Guest Blog spot.=================================================================TheMACD (Moving Average Convergence Divergence) is a trend-following momentumindicator that shows the relationship between two moving averages of prices.The MACD is calculated by subtracting the 26-day exponential moving average(EMA) from the 12-day EMA. A nine-day EMA of the MACD, called the “signalline”, is then plotted on top of the MACD, functioning as a trigger for buy andsell signals when trading the forex market.FirstSome HistoryDevelopedby Gerald Appel,Moving Average Convergence/Divergence (MACD)is one of the simplest and most reliable indicators available.MACDuses moving averages, which are lagging indicators, to include sometrend-following characteristics.Theselagging indicators are turned into a momentum oscillator by subtracting thelonger moving average from the shorter moving average. The resulting plot formsa line that oscillates above and below zero, without any upper or lower limits.Benefitsof the MACDOneof the primary benefits of MACD is that it incorporates aspects of bothmomentum and trend in one indicator. As a trend-following indicator, it willnot be wrong for very long.Theuse of moving averages ensures that the indicator will eventually follow themovements of the underlying security. By using exponential moving averages, asopposed to simple moving averages, some of the lag has been taken out.MACDSetupThedefault settings for the MACD which we will use are:Slowmoving average - 26 days
Fast moving average - 12 days
Signal line - 9 day moving average of the difference between fast and slow.
All moving averages are exponential.Althoughthere are three moving averages mentioned you will only see two lines. Thesimplest method of use is when the two lines cross. If the faster signal linecrosses above the MACD line ( The MACD line is calculated by the differencebetween the 26-day exponential moving average and the 12-day exponential movingaverage) then a buy signal is generated and vice versa.Thehigher above the zero both lines are the more overbought it becomes and thelower below the zero line both lines are the more oversold it becomes.Itmay also lead to a stronger signal if the signal line crosses down when it isoverbought and crosses up when it is oversold.Thelast common use of MACD is that of divergence.Ifthe MACD is making new lows and the price of the security is not making newlows that is one form of divergence (bullish divergence).Also,if the MACD has made a high and starts to head down but price continues up thatis another type of divergence (bearish divergence) and may lead to anindication of a change in direction.Thereare many ways to trade the MACD but one of our favourites are too use twodifferent time frames. All we do is establish a trend in a higher time periodthan the one we intend to trade. For our higher time frame welike to use the 30min chart and then drop down to the 5 min chart when conditions have been meton the 30 min chart.Onthe 30 min forex trading chart below there was a typical buy signal. The chartbelow (red arrow) shows the fast 9-day signal EMA (grey line) crossing over theMACD line EMA (green line).

After confirming the signal on the 30 min chart we then dropped to the5min chart and bought the rallies wherever the MACD crossed up, confident tostay long (to buy) as long as our higher time period MACD trend in the 30 minstayed intact. If the 30 min MACD signal line were to cross down we would haveclosed all long positions.

ConclusionTheMACD is not particularly good for identifying overbought and oversold levelseven though it is possible to identify levels that historically representoverbought and oversold levels. The MACD does not have any upper or lowerlimits to bind its movement and can continue to overextend beyond historicalextremes.Alsothe MACD calculates the absolute difference between two moving averages and notthe percentage difference. The MACD is calculated by subtracting one movingaverage from the other. As a security increases in price, the difference (bothpositive and negative) between the two moving averages is destined to grow.This makes its difficult to compare MACD levels over a long period of time,especially for stocks that have grown exponentially.Withsome charts you can set the MACD as a histogram. The histogram represents thedifference between MACD and its 9-day EMA. The histogram is positive when MACDis above its 9-day EMA and negative when MACD is below its 9-day EMA.Thathaving said, the MACD still is and will always be one of the few indicatorsthat all traders love and use daily and in many ways it is an old familiarfriend you know you can rely on.Thankyou for joining us in this forex trading lesson.

外汇交易与MACD
与MACD的交易
2008年6月26日·来自Blogger的Filed Under General  
在收到许多请求后，我联系了DayTradeology的t ea m，帮助解释如何使用MACD和外汇。PL EA本身让我知道你在想什么来宾博客现货。
================================================== ===============
MAD（移动平均收敛分散）是趋势随后的动量指标，显示价格的两个移动平均线之间的关系。MACD通过从12天EMA中减去26天指数移动平均线（EMA）来计算。然后将MACD的九天EMA（称为“信号”）绘制在MACD的顶部，在交易外汇市场时用作购买和卖出信号的触发器。
第一部历史
由Gerald Appel开发，移动平均收敛/发散（MACD）是可用的最简单和最可靠的指标之一。
MACDuses移动平均线，这是滞后指标，包括以下特征。
通过从较短的移动平均值中减去较长的移动平均值，标记指示器变为动量振荡器。所得图形形成在零以上和以下振荡的线，没有任何上限或下限。
MACD的好处
MACD的主要优点是它在一个指标中包含动态和趋势的方面。作为一个趋势跟踪指标，它不会是错误的很长时间。
移动平均线的使用确保指标最终将跟随基本证券的发展。通过使用指数移动平均值，与简单移动平均值相对，已经取出了一些滞后。
MACDSetup
我们将使用的MACD的默认设置是：
慢
移动平均 - 26天快速移动平均 - 12天
信号线 - 9天移动平均的快速和慢速之间的差异。
所有移动平均值都是指数。
虽然有三个移动平均线提到你只会看到两行。最简单的使用方法是两条线交叉。如果在MACD线之上的更快的信号线交叉（MACD线由26天指数移动平均值和12天指数移动平均值之间的差计算），则生成买入信号，反之亦然。
在零线以上，零线以上越是超买，零线以下越低，两线越超卖。
Itmay也是低位EA D到A更强的信号，如果信号线交叉向下，当它处于超卖状态，当它isoverbought和十字架了。
MACD的最常见用法是分歧。
如果MACD正在创造新的低点，安全的价格不是作为一种形式的分歧（看涨分歧）的新货。
此外，如果MACD取得了高，并开始到h EA d往下但价格继续向上thatis另一种类型的发散（二EA里什发散）和可升EA d，来改变方向的anindication。
疗法EA重新多种方式进行交易MACD但我们的最爱过于使用twodifferent时间框架之一。我们所做的一切都是在我们打算进行交易的时间段内建立一个趋势。对于我们更高的时间框架，使用30分钟图表，然后下降到5分钟图表，当条件已经在30分钟图表。
Onthe 30分外汇交易图表下面有一个典型的买入信号。下图（红色箭头）显示了跨越MACD线EMA（绿线）的快速9天信号EMA（灰线）。
  
在30分钟图上确认信号后，我们下降到5分钟图，买入MACD交叉的地方，只要我们的较高时期MACD趋势在30分钟内完好无损，MACD交叉的任何地方。如果30分钟MACD信号线下跌，我们将关闭所有长仓。
  
结论
虽然有可能识别历史上代表超买水平和超卖水平的水平，但是MACAC不是特别好地识别超买和超卖水平。MACD没有任何上限或下限来约束其运动，并且可以继续超越历史上极限。
Alsothe MACD计算两个移动平均值之间的绝对差值，而不是计算百分比差值。通过从另一个减去一个移动平均值来计算MACD。作为安全增量EA在价格SES，两个移动平均注定grow.This之间的差（bothpositive和负）使得其难以MACD水平以上的很长一段时间比较，特别是对于已经呈指数增长的股票。
使用一些图表，您可以将MACD设置为直方图。直方图表示MACD和其9天EMA之间的差异。当MACD高于其9天的EMA时，直方图为正，而当MACD低于其9天的EMA时，直方图为负。
Thathaving说，MACD仍然是，并将永远是所有交易者喜欢和使用每日的少数指标之一，在许多方面，它是一个老熟悉的朋友，你知道你可以依靠。

这是用在30分钟的图形上面吗？
