Traders use the interaction of these elements — principally crossovers and divergences — to gauge whether a trend is strengthening, weakening, or likely to reverse.[\\[1\\]](#cite-id-c8r95k3vc9)​[\\[3\\]](#cite-id-yu26dis3n5)​\n\n## Components and Calculation\n\nThe MACD is built exclusively from exponential moving averages (EMAs) rather than simple moving averages (SMAs). A moving average represents the average closing price of an asset over a set number of periods; an SMA weights each data point equally, while an EMA assigns greater weight to the most recent prices and therefore reacts faster to short-term price changes.[\\[1\\]](#cite-id-c8r95k3vc9)​[\\[3\\]](#cite-id-yu26dis3n5) \n\nThis reliance on EMAs means the indicator can respond relatively quickly to changes of direction in the current price move.[\\[2\\]](#cite-id-rwzu28ipnc)​\n\nThe **MACD line** is calculated by subtracting the 26-period EMA from the 12-period EMA. A positive value means the 12-period EMA sits above the 26-period EMA, generally associated with upward price momentum, while a negative value indicates the longer-term 26-period average is dominant, suggesting downward momentum.[\\[1\\]](#cite-id-c8r95k3vc9)​[\\[3\\]](#cite-id-yu26dis3n5) The MACD line therefore reflects when the two averages are changing relative to their original positions.[\\[3\\]](#cite-id-yu26dis3n5)​\n\nThe **signal line** is a 9-period EMA applied to the MACD line itself, producing a smoothed, slower-moving version of that line.[\\[1\\]](#cite-id-c8r95k3vc9)​[\\[2\\]](#cite-id-rwzu28ipnc) Because it averages the MACD line over time, the signal line lags behind it, and the points where the two cross form the indicator's most-watched trade signals.[\\[3\\]](#cite-id-yu26dis3n5)​\n\nThe **MACD histogram** is a bar chart that plots the difference between the MACD line and the signal line at each point in time. Histogram bars are positive when the MACD line is above the signal line and negative when it is below, so the histogram visually shows whether the gap between the two lines is widening or narrowing.[\\[1\\]](#cite-id-c8r95k3vc9)​[\\[2\\]](#cite-id-rwzu28ipnc)​\n\nThe histogram is unrelated to an asset's trading volume, a common point of confusion given its bar-chart appearance.[\\[1\\]](#cite-id-c8r95k3vc9) \n\nAll three elements — the MACD line, the signal line, and the histogram — oscillate above and below the zero line, also called the centerline.[\\[3\\]](#cite-id-yu26dis3n5)​\n\n## Settings and Timeframes\n\nThe default MACD configuration is written as (12, 26, 9), referring to the 12-period EMA, the 26-period EMA, and the 9-period EMA used to compute the signal line. These settings are traditionally applied to daily charts, and the indicator is generally considered best used with daily periods.[\\[1\\]](#cite-id-c8r95k3vc9)​[\\[2\\]](#cite-id-rwzu28ipnc) Some traders in traditional markets adjust these values to (5, 35, 5) for longer-term weekly or monthly charts.[\\[1\\]](#cite-id-c8r95k3vc9)​\n\nIn [cryptocurrency](https://iq.wiki/wiki/cryptocurrency) markets, shortening the EMA periods to make the MACD more sensitive generally increases noise and produces more false signals. This is attributed to crypto assets trading continuously around the clock — without the overnight and weekend gaps of traditional markets — and to their relatively higher volatility. \n\nAs a result, most crypto traders retain the default (12, 26, 9) settings and instead vary the chart timeframe, such as 4-hour, daily, or weekly intervals, to match their trading horizon.[\\[1\\]](#cite-id-c8r95k3vc9)​\n\n## Interpretation and Signals\n\n### Crossovers\n\nThe MACD generates its primary signals through two kinds of crossovers. A **signal line crossover** occurs when the MACD line crosses the signal line: a bullish crossover, in which the MACD line rises above the signal line, is often interpreted as a potential entry or buy signal, while a bearish crossover, in which the MACD line falls below the signal line, may be read as a potential exit or sell signal.[\\[1\\]](#cite-id-c8r95k3vc9)​[\\[2\\]](#cite-id-rwzu28ipnc) \n\nA **centerline crossover** occurs when the MACD line crosses the zero line: a cross above zero indicates the 12-period EMA has moved above the 26-period EMA and is associated with strengthening upward momentum, while a cross below zero may indicate building downward momentum. Centerline crossovers tend to lag behind actual price turns.[\\[1\\]](#cite-id-c8r95k3vc9)​\n\nThe position of a signal line crossover relative to the centerline provides important context. A bullish signal line crossover occurring while the MACD line is still below zero may suggest the broader trend remains bearish, whereas a bearish crossover while the MACD line is above zero may represent only a short-term pullback within a broader uptrend rather than a full reversal.[\\[1\\]](#cite-id-c8r95k3vc9) \n\nInvestopedia frames the same principle in terms of the prevailing trend: a MACD line crossing above its signal line after a brief downside correction within a longer-term uptrend qualifies as a bullish confirmation and likely continuation, while a cross below the signal line after a brief move higher within a longer-term downtrend is treated as a bearish confirmation.[\\[2\\]](#cite-id-rwzu28ipnc) Crossovers are considered less reliable during sideways or range-bound markets, where frequent crossings can generate many misleading signals.[\\[1\\]](#cite-id-c8r95k3vc9)​\n\n### Divergence\n\nMACD divergence describes a situation in which the direction of the indicator and the direction of the asset's price move differently.[\\[1\\]](#cite-id-c8r95k3vc9) \n\nRegular divergences may suggest a trend is losing momentum and that a reversal is possible. A regular bearish divergence occurs when price makes a higher high while the MACD makes a lower high, and a regular bullish divergence occurs when price makes a lower low while the MACD makes a higher low.[\\[1\\]](#cite-id-c8r95k3vc9) Investopedia similarly describes a [bullish](https://iq.wiki/wiki/bullish) divergence as the MACD forming two rising lows while price forms two falling lows — often a valid signal when the long-term trend is still positive — and a bearish divergence as the MACD forming two falling highs while price forms two rising highs, which during a long-term downtrend confirms likely continuation.[\\[2\\]](#cite-id-rwzu28ipnc)​\n\nHidden divergences, by contrast, tend to signal trend continuation rather than reversal. A hidden bullish divergence occurs when price makes a higher low while the MACD makes a lower low, and a hidden bearish divergence occurs when price makes a lower high while the MACD makes a higher high.[\\[1\\]](#cite-id-c8r95k3vc9) \n\nAll four divergence types can produce false signals, especially in fast-moving or highly volatile markets, and are generally considered more significant when they develop over longer timeframes or align with key support and resistance levels identified by other tools such as candlestick patterns or classical chart patterns.[\\[1\\]](#cite-id-c8r95k3vc9)​\n\n### Rapid Moves and Overbought Conditions\n\nWhen the MACD rises or falls rapidly — the shorter-term moving average pulling sharply away from the longer-term one — it can signal that a security is overbought or oversold and may soon retrace toward normal levels.[\\[2\\]](#cite-id-rwzu28ipnc) \n\nUnlike bounded oscillators, the MACD lines have no concrete overbought or oversold thresholds and function on a relative basis, which is why traders frequently pair such readings with other indicators to verify the condition.[\\[2\\]](#cite-id-rwzu28ipnc) \n\nSome traders also treat the histogram as a tool for anticipating trend changes, and for them this aspect can function more like a leading indicator even though the MACD itself is lagging.[\\[2\\]](#cite-id-rwzu28ipnc)​\n\n## Limitations and Use with Other Indicators\n\nBecause the MACD is derived from moving averages, it always trails current market conditions. In fast-moving markets, its signals can arrive only after a significant portion of a price move has already occurred, and the indicator performs poorly in ranging or sideways markets, where frequent crossings produce meaningless signals.[\\[1\\]](#cite-id-c8r95k3vc9) \n\nDivergence in particular is prone to numerous false positives, often when price moves sideways in consolidation such as range or triangle patterns, because a slowdown in momentum causes the MACD to gravitate toward the zero line even without a genuine reversal.[\\[2\\]](#cite-id-rwzu28ipnc) In [cryptocurrency](https://iq.wiki/wiki/cryptocurrency) markets, continuous around-the-clock trading and elevated volatility can further amplify noise, particularly on shorter timeframes.[\\[1\\]](#cite-id-c8r95k3vc9)​\n\nFor these reasons the MACD is most often used alongside complementary indicators to confirm its signals. The Relative Strength Index (RSI) is commonly used to check momentum against overbought and oversold conditions; the RSI defaults to 14 periods and is bounded between 0 and 100, with readings above 70 suggesting overbought conditions and below 30 suggesting oversold conditions. Because the MACD measures the relationship between two EMAs while the RSI evaluates recent price action on an absolute scale, the two can sometimes give contradictory results and are frequently applied together.[\\[2\\]](#cite-id-rwzu28ipnc) \n\nOther named complements include [Bollinger Bands](https://iq.wiki/wiki/bollinger-bands), which provide volatility context for crossovers, and the Stochastic RSI, used to cross-confirm momentum signals.[\\[1\\]](#cite-id-c8r95k3vc9)​\n\nTrend-following tools are also used for confirmation, in particular the Directional Movement Index (DMI) system and its key component, the Average Directional Index (ADX). The ADX indicates whether a trend is actually in place: a reading above 25 signals a trend in either direction, while a reading below 20 suggests no trend is present.[\\[2\\]](#cite-id-rwzu28ipnc) Across all of these pairings, the general guidance is that MACD crossovers should be noted but that confirmation from subsequent price action and from additional technical signals should be sought before acting on them.[\\[2\\]](#cite-id-rwzu28ipnc)​\n","categories":[{"id":"glossary","title":"glossary"}],"tags":[],"images":[{"id":"QmUvXKSNeGSqc7ReFSL97nP4wVvoJT7fCdGBgoVRf6HUL1","type":"image/jpeg, image/png"}],"media":[],"metadata":[{"id":"references","value":"[{\"id\":\"c8r95k3vc9\",\"url\":\"https://www.binance.com/en/academy/articles/macd-indicator-explained\",\"description\":\"Binance Academy on MACD as momentum oscillator\",\"timestamp\":1791386722653},{\"id\":\"rwzu28ipnc\",\"url\":\"https://www.investopedia.com/terms/m/macd.asp\",\"description\":\"Investopedia on MACD measuring momentum\",\"timestamp\":1791386722653},{\"id\":\"yu26dis3n5\",\"url\":\"https://coinmarketcap.com/academy/glossary/moving-average-convergence-divergence-macd\",\"description\":\"CoinMarketCap on Appel and MACD origin\",\"timestamp\":1791386722653}]"},{"id":"main-image-origin","value":"{\"imageId\":\"QmUvXKSNeGSqc7ReFSL97nP4wVvoJT7fCdGBgoVRf6HUL1\",\"originalId\":\"QmUvXKSNeGSqc7ReFSL97nP4wVvoJT7fCdGBgoVRf6HUL1\"}"},{"id":"commit-message","value":"Add Moving Average Convergence Divergence (MACD) wiki"}],"events":[{"type":"DEFAULT","title":"Binance Academy article \"What Is the MACD Indicator?\" published","date":"2019-03-01","description":"Binance Academy published an explanatory article defining MACD, its components (MACD line, signal line, histogram), default settings (12, 26, 9), interpretations (crossovers, divergences, centerline), uses in crypto, and limitations; includes educational ","link":"https://www.binance.com/en/academy/articles/macd-indicator-explained","multiDateStart":null,"multiDateEnd":null,"id":"21c345e4-2020-4c4b-bfc5-eba0e273408c"},{"type":"DEFAULT","title":"Investopedia article update: \"What Is MACD?\" reviewed and updated","date":"2026-05-01","description":"Investopedia (article by Brian Dolan, reviewed by Samantha Silberstein) updated its MACD entry, covering definition, calculation (12‑period EMA − 26‑period EMA; 9‑period signal EMA), histogram usage, interpretation (crossovers, divergences, rapid moves), ","link":"https://www.investopedia.com/terms/m/macd.asp","multiDateStart":null,"multiDateEnd":null,"id":"fb9c37fa-24c3-46ba-a790-1421632284b1"}],"linkedWikis":{"founders":[],"blockchains":[],"speakers":[]},"user":{"id":"0x8af7a19a26d8fbc48defb35aefb15ec8c407f889"},"author":{"id":"0x212Cb3F4aE6611054637f9f78F18fB628AD258bb"},"language":"en","operator":{"id":"0x212Cb3F4aE6611054637f9f78F18fB628AD258bb"}}
