For many stock traders, four letters can spell the difference between a winning and losing position. MACD (moving average convergence divergence) ranks among the key stock market indicators (along with moving averages and RSI) that traders use consistently in their analysis.<blockquote>MACD 和 MACD 直方图可以提升您的交易组合。对于许多股票交易者来说，四个字母可以拼出盈利和亏损头寸之间的区别。MACD（移动平均线收敛背离）是交易者在分析中始终使用的关键股票市场指标（以及移动平均线和RSI）之一。</blockquote> Let’s discuss a number of creative ways to use this powerful and versatile gauge.<blockquote>让我们来讨论一下使用这种强大而多功能的仪表的一些创造性方法。</blockquote> MACD, introduced in the late 1970s, is a trend-following momentum indicator.&nbsp; It helps to determine when a trend, and its associated momentum (i.e., directional speed and duration) has ended or begun, or might reverse direction.<blockquote>MACD于20世纪70年代末推出，是一种趋势跟踪动量指标。它有助于确定一个趋势及其相关的动量（即方向速度和持续时间）何时结束或开始，或者可能反转方向。</blockquote> Be aware that MACD is a “lagging” or “backward-looking” indicator, which means its signals are delayed, but don’t let that deter you. When MACD yields a signal, it is often significant, especially if used on a weekly chart (versus the daily chart favored by short-term traders). In fact, the longer the MACD time frame, the more valid the results, which is one reason longer-term traders like myself prefer to use a weekly chart.<blockquote>请注意，MACD 是一个 “滞后 ”或 “回顾性 ”指标，这意味着它的信号是延迟的，但不要因此而望而却步。当 MACD 产生信号时，它通常很重要，尤其是在周线图上使用时（相对于短线交易者青睐的日线图）。事实上，MACD时间范围越长，结果就越有效，这也是像我这样的长期交易者更喜欢使用周线图的原因之一。</blockquote> When you view MACD on a chart, you see two lines. The black line is referred to as the “MACD line.” The gray (or red) line is referred to as the “signal line.” Remember: the MACD line is the leader line, while the signal line is the laggard line.<blockquote>当你在图表上查看MACD时，你会看到两条线。黑线被称为 “MACD 线”。灰色(或红色)线被称为“信号线”。记住：MACD线是领先线，而信号线是落后线。</blockquote> In addition, a horizontal line runs across the chart called the “zero line” (0 line).&nbsp; The main function of the zero line is to alert you to the primary trend of the underlying price action.<blockquote>此外，图表上还有一条水平线，称为 “零线”（0 线）。零线的主要功能是提醒您注意基础价格走势的主要趋势。</blockquote> Four simple trading signals<blockquote>四个简单的交易信号</blockquote> At its most basic level, MACD generates four signals:<blockquote>在最基本的水平上，MACD 会产生四个信号：</blockquote> Buy:When the MACD line crosses above the zero line, it’s bullish.<blockquote>购买：当 MACD 线穿过零线上方时，则为看涨。</blockquote> Buy:When the MACD line crosses above the nine-day signal line, it’s bullish.<blockquote>购买：当 MACD 线穿过九日信号线上方时，则为看涨。</blockquote> Sell:When the MACD line crosses below the zero line, it’s bearish.<blockquote>出售：当 MACD 线穿过零线下方时，则为看跌。</blockquote> Sell:When the MACD line crosses below the nine-day signal line, it’s bearish.<blockquote>出售：当 MACD 线穿过九日信号线下方时，则为看跌。</blockquote> Note: When both the MACD line and nine-day signal line move in the same direction (uptrend or downtrend), that is a stronger, more significant signal.<blockquote>注意：当MACD线和九日信号线都朝同一方向移动（上升趋势或下降趋势）时，这是一个更强、更重要的信号。</blockquote> Keep in mind that just because MACD generates a buy or sell signal does not mean it is an actionable trade. Like that of any indicator, there are false signals. In addition, it’s essential that you confirm with other indicators before betting real money on a trade. Think of these MACD buy and sell signals as guidelines, not rules.<blockquote>请记住，仅仅因为MACD产生买入或卖出信号并不意味着它是一个可操作的交易。像任何指标一样，也有错误信号。此外，在用真金白银进行交易之前，还必须与其他指标进行确认。将这些 MACD 买卖信号视为指导方针，而不是规则。</blockquote> Another limitation of MACD is that it does not work as well at stock market tops or when market volatility is low. Therefore, if you use MACD on the Dow Jones Industrial AverageDJIA,-0.48%or the S&amp;P 500SPX,-0.91%in this current market, the signal is not as useful. That is why you should use MACD on individual stocks until volatility returns to the major market indexes.<blockquote>MACD 的另一个局限性是，它在股市顶部或市场波动性较低时效果不佳。因此，如果您在当前市场上使用道琼斯工业平均指数 JIA,-0.48% 或标准普尔 500SPX,-0.91% 的 MACD，则该信号就没有那么有用了。这就是为什么你应该在个股上使用MACD，直到波动性回到主要市场指数。</blockquote> What MACD says about Tesla now<blockquote>MACD 现在对特斯拉的评价</blockquote> For example, the weekly stock chart of TeslaTSLA,+0.33%shows its MACD is above the zero line, and the MACD line is above the signal line. Tesla is also above its moving averages.<blockquote>比如特斯拉TSLA,+0.33%的周线图显示其MACD在零线上方，MACD线在信号线上方。特斯拉也高于其移动平均线。</blockquote> Based on this information, Tesla stock currently is a short-term “strong” buy.&nbsp;If Tesla’s MACD line drops below its signal line while both lines are above the zero line, the shares would be a “moderate” buy.<blockquote>根据这一信息，特斯拉股票目前值得短期 “强力 ”买入。如果特斯拉的 MACD 线跌破其信号线，而两条线都高于零线，则该股将是 “适度 ”买入。</blockquote> A few years ago, I spoke with MACD’s creator, Gerald Appel. He told me that he created MACD in the late 1970s by entering numbers into a punch machine and a spreadsheet. After the personal computer was invented, he was able to automate the process.<blockquote>几年前，我采访了 MACD 的创始人杰拉尔德-阿佩尔（Gerald Appel）。他告诉我，他在 20 世纪 70 年代末通过将数字输入打孔机和电子表格创建了 MACD。个人电脑发明后，他能够自动化这个过程。</blockquote> Appel expressed surprise that MACD became so popular. “It works because it’s adaptable to any time frame,” he said. “You can get a good reading of the major trend of the market by using MACD patterns that are based on monthly data. You can also use it on a five-minute chart.”<blockquote>阿佩尔对 MACD 变得如此受欢迎表示惊讶。“他说：”它之所以有效，是因为它可以适应任何时间框架。“通过使用基于月度数据的 MACD 形态，您可以很好地解读市场的主要趋势。您也可以在五分钟图表上使用它”。</blockquote> MACD gives the most precise signals at market bottoms. Said Appel: “It’s more accurate at market low points than high points because of the way the market behaves. Market bottoms tend to be very sharp and pronounced, while tops tend to be broad and slow. It’s also possible for the market averages to keep drifting upwards while more and more stocks are falling.”<blockquote>MACD在市场底部给出最精确的信号。阿佩尔说： “由于市场的行为方式，它在市场低点比在高点更准确。市场底部往往非常尖锐和明显，而顶部往往宽阔而缓慢。在越来越多的股票下跌的情况下，市场平均线也有可能继续向上漂移”。</blockquote> Appel cautioned that you must confirm MACD signals against other indicators. “No indicator is infallible,” he said. “You might get a market rise and MACD turns down. Perhaps you think this is a sell signal. Well, it might not be.”<blockquote>Appel 警告说，您必须根据其他指标确认 MACD 信号。“他说：”没有任何指标是万无一失的。“你可能会看到市场上涨，而 MACD 会下跌。也许你认为这是一个卖出信号。但事实并非如此。”</blockquote> Appel added that he likes to work with different MACD time frames simultaneously. For example, if the short-term MACD turns up along with the intermediate MACD, he’s more confident that the signal is valid.<blockquote>Appel补充说，他喜欢同时使用不同的MACD时间框架。例如，如果短期 MACD 与中期 MACD 同时出现，他就更有信心该信号是有效的。</blockquote> The MACD-Histogram<blockquote>MACD直方图</blockquote> One of the most powerful (but often ignored) additions to the MACD is the MACD-Histogram. Developed by Thomas Aspray in 1986, this oscillator is used to gauge momentum. It is a separate program that should be available on your charting package.&nbsp;Traders who use this feature typically view both MACD and the histogram on a stock chart simultaneously.<blockquote>MACD 最强大（但经常被忽视）的附加功能之一是 MACD 直方图。这种振荡器由托马斯·阿斯普雷于1986年开发，用于测量动量。这是一个单独的程序，应该在你的图表包上提供。使用此功能的交易者通常会同时查看股票图表上的MACD和直方图。</blockquote> The histogram is a series of bar graphs at the bottom of the stock screen. If the bars move above the zero line, it means the underlying stock (or index) is gaining strength, i.e., momentum. If the bars move below the zero line, the stock or index is losing strength.<blockquote>直方图是股票屏幕底部的一系列条形图。如果柱状图移动到零线上方，则意味着标的股票（或指数）正在增强，即动量。如果柱状图移动到零线以下，股票或指数就会失去强度。</blockquote> Many beginning traders don’t realize that momentum always changes before price does. That is what makes MACD and the MACD-Histogram so valuable. Both indicators detect when momentum is weakening. It could also be a signal to become bullish if the histogram bars move above the zero line.<blockquote>许多新手交易者没有意识到，动量总是先于价格发生变化。这就是 MACD 和 MACD 直方图如此有价值的原因。这两个指标都能检测到势头何时减弱。如果直方图柱状图移动到零线上方，这也可能是一个看涨的信号。</blockquote> Histogram signals<blockquote>直方图信号</blockquote> <ol> <li>If the MACD-Histogram bar changes to a lighter color, it means that momentum is diminishing. It is not a sell signal; it simply means that enthusiasm for that particular stock is waning.</li> </ol> <ol> <li>As mentioned earlier, if the histogram bar rises above the zero line, that is a buy signal. An uptrend may be developing. If the histogram bar drops below the zero line, that is a sell signal. A downtrend may be developing.</li> </ol> Red flags<blockquote><ol><li>如果 MACD 直方图柱状图变为浅色，则意味着动量正在减弱。这不是卖出信号；这仅仅意味着对该特定股票的热情正在减弱。</li></ol><ol><li>如前所述，如果直方图柱状图升至零线以上，则为买入信号。上升趋势可能正在形成。如果直方图条跌破零线，则为卖出信号。下降趋势可能正在形成。</li></ol>红旗</blockquote> If you see the index prices as well as stock prices move higher, but MACD turns lower, that is a red flag. In addition, if you see the MACD-Histogram changing colors and the bars getting shorter, that confirms momentum is weakening (but confirm this against RSI or stochastics).<blockquote>如果你看到指数价格和股票价格走高，但MACD走低，这是一个危险信号。此外，如果您看到 MACD 直方图颜色变化且柱状图变短，则证实动量正在减弱（但根据 RSI 或随机指标证实这一点）。</blockquote> If you have never used MACD or MACD-Histogram, give it a try. Use these measures for any stock that has hit bottom and is on its way higher. They’ll help confirm whether the stock has legs or is a just giving traders a head fake.<blockquote>如果您从未使用过 MACD 或 MACD 直方图，请尝试一下。对于任何已经触底并正在上涨的股票，请使用这些指标。他们将帮助确认这只股票是有腿的，还是只是给交易者一个假头。</blockquote> Michael Sincere&nbsp;(michaelsincere.com) is the author of “Understanding Options” and “Understanding Stocks.”<blockquote>Michael Sincere (michaelsincere.com) 是《了解期权》和《了解股票》的作者。</blockquote>","source":"lsy1603348471595","collect":0,"html":"<!DOCTYPE html>\n<html>\n<head>\n<meta http-equiv=\"Content-Type\" content=\"text/html; charset=utf-8\" />\n<meta name=\"viewport\" content=\"width=device-width,initial-scale=1.0,minimum-scale=1.0,maximum-scale=1.0,user-scalable=no\"/>\n<meta name=\"format-detection\" content=\"telephone=no,email=no,address=no\" />\n<title>Savvy stock traders use these 2 insider tips to know when to buy and sell<blockquote>精明的股票交易者使用这 2 个内部提示来了解何时买卖</blockquote></title>\n<style type=\"text/css\">\na,abbr,acronym,address,applet,article,aside,audio,b,big,blockquote,body,canvas,caption,center,cite,code,dd,del,details,dfn,div,dl,dt,\nem,embed,fieldset,figcaption,figure,footer,form,h1,h2,h3,h4,h5,h6,header,hgroup,html,i,iframe,img,ins,kbd,label,legend,li,mark,menu,nav,\nobject,ol,output,p,pre,q,ruby,s,samp,section,small,span,strike,strong,sub,summary,sup,table,tbody,td,tfoot,th,thead,time,tr,tt,u,ul,var,video{ font:inherit;margin:0;padding:0;vertical-align:baseline;border:0 }\nbody{ font-size:16px; line-height:1.5; color:#999; background:transparent; }\n.wrapper{ overflow:hidden;word-break:break-all;padding:10px; }\nh1,h2{ font-weight:normal; line-height:1.35; margin-bottom:.6em; }\nh3,h4,h5,h6{ line-height:1.35; margin-bottom:1em; }\nh1{ font-size:24px; }\nh2{ font-size:20px; }\nh3{ font-size:18px; }\nh4{ font-size:16px; }\nh5{ font-size:14px; }\nh6{ font-size:12px; }\np,ul,ol,blockquote,dl,table{ margin:1.2em 0; }\nul,ol{ margin-left:2em; }\nul{ list-style:disc; }\nol{ list-style:decimal; }\nli,li p{ margin:10px 0;}\nimg{ max-width:100%;display:block;margin:0 auto 1em; }\nblockquote{ color:#B5B2B1; border-left:3px solid #aaa; padding:1em; }\nstrong,b{font-weight:bold;}\nem,i{font-style:italic;}\ntable{ width:100%;border-collapse:collapse;border-spacing:1px;margin:1em 0;font-size:.9em; }\nth,td{ padding:5px;text-align:left;border:1px solid #aaa; }\nth{ font-weight:bold;background:#5d5d5d; }\n.symbol-link{font-weight:bold;}\n/* header{ border-bottom:1px solid #494756; } */\n.title{ margin:0 0 8px;line-height:1.3;color:#ddd; }\n.meta {color:#5e5c6d;font-size:13px;margin:0 0 .5em; }\na{text-decoration:none; color:#2a4b87;}\n.meta .head { display: inline-block; overflow: hidden}\n.head .h-thumb { width: 30px; height: 30px; margin: 0; padding: 0; border-radius: 50%; float: left;}\n.head .h-content { margin: 0; padding: 0 0 0 9px; float: left;}\n.head .h-name {font-size: 13px; color: #eee; margin: 0;}\n.head .h-time {font-size: 12.5px; color: #7E829C; margin: 0;}\n.small {font-size: 12.5px; display: inline-block; transform: scale(0.9); -webkit-transform: scale(0.9); transform-origin: left; -webkit-transform-origin: left;}\n.smaller {font-size: 12.5px; display: inline-block; transform: scale(0.8); -webkit-transform: scale(0.8); transform-origin: left; -webkit-transform-origin: left;}\n.bt-text {font-size: 12px;margin: 1.5em 0 0 0}\n.bt-text p {margin: 0}\n</style>\n</head>\n<body>\n<div class=\"wrapper\">\n<header>\n<h2 class=\"title\">\nSavvy stock traders use these 2 insider tips to know when to buy and sell<blockquote>精明的股票交易者使用这 2 个内部提示来了解何时买卖</blockquote>\n</h2>\n<h4 class=\"meta\">\n\nMarketWatch2021-09-20 15:34\n\n</h4>\n</header>\n<article>\n MACD and the MACD-Histogram can give your trading portfolio a boost.

MACD (moving average convergence divergence) ranks among the key stock market indicators (along with moving averages and RSI) that traders use consistently in their analysis.\nLet’s discuss a number of creative ways to use this powerful and versatile gauge.\nMACD, introduced in the late 1970s, is a trend-following momentum indicator.  It helps to determine when a trend, and its associated momentum (i.e., directional speed and duration) has ended or begun, or might reverse direction.\nBe aware that MACD is a “lagging” or “backward-looking” indicator, which means its signals are delayed, but don’t let that deter you. When MACD yields a signal, it is often significant, especially if used on a weekly chart (versus the daily chart favored by short-term traders). In fact, the longer the MACD time frame, the more valid the results, which is one reason longer-term traders like myself prefer to use a weekly chart.\nWhen you view MACD on a chart, you see two lines. The black line is referred to as the “MACD line.” The gray (or red) line is referred to as the “signal line.” Remember: the MACD line is the leader line, while the signal line is the laggard line.\nIn addition, a horizontal line runs across the chart called the “zero line” (0 line).  The main function of the zero line is to alert you to the primary trend of the underlying price action.\nFour simple trading signals\nAt its most basic level, MACD generates four signals:\nBuy:When the MACD line crosses above the zero line, it’s bullish.\nBuy:When the MACD line crosses above the nine-day signal line, it’s bullish.\nSell:When the MACD line crosses below the zero line, it’s bearish.\nSell:When the MACD line crosses below the nine-day signal line, it’s bearish.\nNote: When both the MACD line and nine-day signal line move in the same direction (uptrend or downtrend), that is a stronger, more significant signal.\nKeep in mind that just because MACD generates a buy or sell signal does not mean it is an actionable trade. Like that of any indicator, there are false signals. In addition, it’s essential that you confirm with other indicators before betting real money on a trade. Think of these MACD buy and sell signals as guidelines, not rules.\nAnother limitation of MACD is that it does not work as well at stock market tops or when market volatility is low. Therefore, if you use MACD on the Dow Jones Industrial AverageDJIA,-0.48%or the S&P 500SPX,-0.91%in this current market, the signal is not as useful. That is why you should use MACD on individual stocks until volatility returns to the major market indexes.\nWhat MACD says about Tesla now\nFor example, the weekly stock chart of TeslaTSLA,+0.33%shows its MACD is above the zero line, and the MACD line is above the signal line. Tesla is also above its moving averages.\nBased on this information, Tesla stock currently is a short-term “strong” buy. If Tesla’s MACD line drops below its signal line while both lines are above the zero line, the shares would be a “moderate” buy.\nA few years ago, I spoke with MACD’s creator, Gerald Appel. He told me that he created MACD in the late 1970s by entering numbers into a punch machine and a spreadsheet. After the personal computer was invented, he was able to automate the process.\nAppel expressed surprise that MACD became so popular. “It works because it’s adaptable to any time frame,” he said. “You can get a good reading of the major trend of the market by using MACD patterns that are based on monthly data. You can also use it on a five-minute chart.”\nMACD gives the most precise signals at market bottoms. Said Appel: “It’s more accurate at market low points than high points because of the way the market behaves. Market bottoms tend to be very sharp and pronounced, while tops tend to be broad and slow. It’s also possible for the market averages to keep drifting upwards while more and more stocks are falling.”\nAppel cautioned that you must confirm MACD signals against other indicators. “No indicator is infallible,” he said. “You might get a market rise and MACD turns down. Perhaps you think this is a sell signal. Well, it might not be.”\nAppel added that he likes to work with different MACD time frames simultaneously. For example, if the short-term MACD turns up along with the intermediate MACD, he’s more confident that the signal is valid.\nThe MACD-Histogram\nOne of the most powerful (but often ignored) additions to the MACD is the MACD-Histogram. Developed by Thomas Aspray in 1986, this oscillator is used to gauge momentum. It is a separate program that should be available on your charting package. Traders who use this feature typically view both MACD and the histogram on a stock chart simultaneously.\nThe histogram is a series of bar graphs at the bottom of the stock screen. If the bars move above the zero line, it means the underlying stock (or index) is gaining strength, i.e., momentum. If the bars move below the zero line, the stock or index is losing strength.\nMany beginning traders don’t realize that momentum always changes before price does. That is what makes MACD and the MACD-Histogram so valuable. Both indicators detect when momentum is weakening. It could also be a signal to become bullish if the histogram bars move above the zero line.\nHistogram signals\n\nIf the MACD-Histogram bar changes to a lighter color, it means that momentum is diminishing. It is not a sell signal; it simply means that enthusiasm for that particular stock is waning.\n\n\nAs mentioned earlier, if the histogram bar rises above the zero line, that is a buy signal. An uptrend may be developing. If the histogram bar drops below the zero line, that is a sell signal. A downtrend may be developing.\n\nRed flags\nIf you see the index prices as well as stock prices move higher, but MACD turns lower, that is a red flag. In addition, if you see the MACD-Histogram changing colors and the bars getting shorter, that confirms momentum is weakening (but confirm this against RSI or stochastics).\nIf you have never used MACD or MACD-Histogram, give it a try. Use these measures for any stock that has hit bottom and is on its way higher. They’ll help confirm whether the stock has legs or is a just giving traders a head fake.\nMichael Sincere (michaelsincere.com) is the author of “Understanding Options” and “Understanding Stocks.”","news_type":1,"symbols_score_info":{".IXIC":0.9,".DJI":0.9,"SPY":0.9,".SPX":0.9}},"isVote":1,"tweetType":1,"viewCount":2512,"commentLimit":10,"likeStatus":false,"favoriteStatus":false,"reportStatus":false,"symbols":["AONE.U"],"verified":2,"subType":0,"readableState":1,"langContent":"EN","currentLanguage":"EN","warmUpFlag":false,"orderFlag":false,"shareable":true,"causeOfNotShareable":"","featuresForAnalytics":[],"commentAndTweetFlag":false,"andRepostAutoSelectedFlag":false,"upFlag":false,"length":44,"subscribersOnly":false,"subscribersOnlyAccessible":false,"xxTargetLangEnum":"ORIG"},"commentList":[],"isCommentEnd":true,"isTiger":false,"isWeiXinMini":false,"url":"/m/post/860481872"}
