The MACD histogram is primarily used to predict price fluctuations and trend reversals. A histogram is reflected above the baseline when the MACD line (blue line) crosses the signal line (orange line) from below. When the MACD line (blue line) is below the signal line (orange line), a histogram is reflected below the baseline. The chart indicates that, in August 2022, the 12-day EMA line crossed the 26-day EMA line from below. In April 2022, the 12-day EMA line crossed the 26-day EMA line from above. In sum, the various conflicting signals generated by MACD may suggest a more neutral market that may not trend up or down.
What Is the MACD Indicator?
While the MACD relies on moving averages, stochastic indicators use a formula based upon current stock prices along with their highest high prices and lowest low prices in the recent past. Contrary to this, when the MACD makes two falling highs that correspond to two rising highs in the stock price, a negative divergence occurs. When a long-term trend remains negative, it confirms a valid bearish signal.
Difference Between MACD and RSI
An EMA is a moving average (MA) that places a greater weight and significance on the most recent data points. The MACD line is calculated by subtracting the 26-period EMA from the 12-period EMA. A nine-day EMA of the MACD line is called the signal line, plotted on top of the MACD line, which can function as a trigger for buy or sell signals.
Short-term buy-and-sell signals are generated by the MACD line and the signal line. If the MACD line crosses above the signal line, this may be interpreted as a buy signal. Alternatively, if the MACD line crosses below the signal line, this may be interpreted as a sell signal. This indicator has been generating frequent buy-and-sell signals over the past several months, as these 2 lines have been closely tracking each other. For example, a buy signal was generated on August 12 and a sell signal was generated on August 19. These periods reflect the most common short-term and medium-term trends in the market, as determined by Gerald Appel, the inventor of the MACD indicator.
As shown in the chart below, rises and drops in MACD (blue) values correspond to the movements of the two EMA lines.

This means that we are taking the average of the last 9 periods of the “faster” MACD Line and plotting it as our “slower” moving average. When looking at the indicator, the Signal Line is considered the “slower” moving average.

- Convergence happens when two moving averages move toward one another, while divergence occurs when the moving averages move away from each other.
- Traders use the MACD’s histogram to identify peaks of bullish or bearish momentum, and to generate overbought/oversold trade signals.
- Later, when the MACD line crosses below the signal line, the trader considers selling to lock in profits before a downturn.
MACD settings for day trading
This kind of investing differs from fundamental investing, which is focused on the performance of the business. In technical investing, traders buy and sell based on the movements in the stock and mostly ignore information on the business, such as earnings reports. During bearish markets, the MACD helps traders identify and confirm downtrends.
MACD Buying Signal
Stock markets are volatile and can fluctuate significantly in response to company, industry, political, regulatory, market, or economic developments. Investing in stock involves risks, including the loss of principal. That said, MACD is still one of the most favored tools by many traders. When a new trend occurs, the faster line (MACD Line) will react first and eventually cross the slower line (Signal Line).

Conversely, when the bars shift from positive to negative, it reflects bearish momentum, often hinting at a downward trend.
Therefore, it is recommended to use price action to assist with trading decisions when using the MACD. Firstly, divergence can often signal a false positive, i.e., a possible reversal, but no actual reversal occurs. This is because prices often demonstrate a few surges or plunges as market participants set off stops to match the supply and demand in the order flow.
- Some traders will look for bullish divergences even when the long-term trend is negative because they can signal a change in the trend, although this technique is less reliable.
- As the moving averages get closer to each other, the histogram gets smaller.
- Moving Average Convergence/Divergence or MACD is a momentum indicator that shows the relationship between two Exponential Moving Averages (EMAs) of a stock price.
- These indicators provide confidence to enter or stay in long positions.
- When MACD forms highs or lows that exceed the corresponding highs and lows in the instrument’s price, it is called a divergence.
MACD helps reveal subtle shifts in the strength and direction of an asset’s trend, guiding traders on when to enter or exit a position. The indicator can be interpreted in several ways, but the more common methods are crossovers, rapid rises/falls, and divergences. Assuming the standard time ranges, the MACD is calculated by subtracting the value of a 26-period exponential moving average from a 12-period EMA. Once you’ve determined the MACD, you can then take the nine-day EMA of the MACD line — called the signal line — and plot that on top of the MACD line as a guide to buy or sell a stock.
Trades in swing trading typically last from a few days to a few weeks. If MACD is below 0 and finds positive divergence, there is a long opportunity. In contrast, if MACD is above 0 and finds negative divergence, there is a short opportunity. Some traders use 24-day EMA, 52-day EMA, and 18-day EMA while trading with 5-minute, 15-minute, 30-minute, 1-hour, and daily charts.
Because it is a lagging indicator, MACD argues that confirmation in subsequent price action should develop before taking the signal. The data used in MACD calculation is based on the historical price action, therefore MACD readings lag the price. However, some traders use MACD histograms to predict when a change in trend will occur. For these traders, this aspect of MACD might be viewed as a leading indicator of future trend changes. Some traders will look for bullish divergences even when the long-term trend is negative because they can signal a change in the trend, although this technique is less reliable. Most charts use a 9-period exponential moving average (EMA) by default.

When the MACD line crosses above the signal line, that’s a buy signal, showing the stock is rallying. When the MACD falls below the signal line, that should trigger a sell. Stochastic indicators are another type of key indicators in technical analysis.
Namely, if the crossover indicates an entry point, but the MACD line indicator is below the zero line (negative), market conditions are still likely to be bearish. On the other hand, if a signal line crossover suggests a potential exit, but the MACD line indicator is above the zero line (positive), market conditions may still be observed to be bullish. Technical indicators like the MACD can give traders further insight into the short-term direction of the market. A crossing of the MACD above or below its signal line may also provide a directional signal for some traders, much as a crossover of the 9-day and 14-day SMAs may. Both Relative Strength Index (RSI) and Moving Average Convergence/Divergence are momentum indicators that show the connection between two moving averages of stock prices. Previously, traders traded stocks using the ‘centerline’ approach, which involved drawing a line at point 0 to distinguish between positive and negative areas.
The crossover strategy is one of the simplest and most widely used approaches in trading. Putting everything above together, here are some MACD trading strategies. These indicators provide confidence to enter or stay in long positions. Centerline crossover patterns are similar to signal line crossover patterns except that they involve only the MACD line and its relationship to the zero/center line. Signal line or DEA is calculated as the 9-day EMA of the difference of EMA 12 and EMA 26.
