When using RSI, a number above 50 suggests market bullishness, while a reading below 50 indicates market bearishness. When the 12-day EMA is below the 26-day EMA, the MACD value is negative. The greater the magnitude of the MACD, the stronger will be the downward trend. A sell signal is given when the signal line or the MACD line crosses below the zero line, and a buy signal is given when either cross above the zero line.
This suggested that the brief downtrend could potentially reverse. When this “crossover” occurs, and the fast line starts to “diverge” or move away from the slower line, it often indicates that a new trend has formed. This is called a MACD divergence because the faster moving average (MACD Line) is “diverging” or moving away from the slower moving average (Signal Line). MACD is highly effective in trending markets but less reliable in sideways or choppy conditions.
With continued practice and thoughtful application, the MACD can significantly contribute to your ability to identify trends and optimize their market positions. One of the major limitations of using MACD is that it cannot correctly forecast all reversals. Sometimes the trend signals may fail or show little movement before a reversal happens. MACD may react quickly to changes in direction in the current price action as more weight is given to the most recent data.
- It was developed to identify changes in the strength, direction, momentum, and duration of a trend in a market.
- Remember, price is the ultimate indicator, with momentum indicators (the MACD histogram is a price derivative and not the price itself) only manipulating price data.
- To easily identify stocks of your choice at crossovers or showing bullish divergence, you can use stock screeners and select the MACD value range of your choice.
- This way, the MACD formula provides a clear view of trend direction and strength.
The MACD crossover happens when the MACD line meets the signal line. If the MACD line crosses the signal line from below during a downward correction when the stock is in a long period of an forex blog uptrend, it confirms a strong bullish signal. If you look at our original chart, you can see that, as the two moving averages (MACD Line and Signal Line) separate, the histogram gets bigger.
Divergence Trading
Conversely, a bearish divergence occurs when the MACD forms two falling highs that line up with two rising highs in the price. There could be instances where some traders might seek bullish or bearish divergences even when the long-term trend is negative or positive since they can herald a change in the trends. MACD indicator identifies the strength of a security’s price trend. It may seem to be complicated at first as it relies on an additional statistical concept known as the Exponential Moving Average (EMA). However, MACD fundamentally supports traders in determining when the recent momentum in a security price may indicate a change in its underlying trend. This helps traders to make appropriate decisions with their entry and exit of trades.

Since both tools provide unique insights, many traders use them together to increase accuracy. In this article, we’ll explore what MACD is, how it’s calculated, and how it compares to RSI, another popular indicator. Confirm the signal by observing a MACD crossover to the downside or a breakdown below a key support level. While 12, 26, and 9 are the typical value settings used with the MACD, traders can opt for other values depending on their trading style and goals.
MACD Indicator Definition & Examples
- It is readily available on most trading platforms offered by top online stock brokers.
- We use cutting-edge AI models to forecast future prices for stocks and crypto.
- The data used in MACD calculation is based on the historical price action, therefore MACD readings lag the price.
- When the reading is between 0 and 30, it suggests that the stock has been severely sold and is due for an upward correction.
- The exponential moving average focuses solely on smoothing price data over a specific period to track the trend direction of an asset.
The MACD shows momentum and trend direction, helping traders identify potential buy and sell opportunities. The Signal Line helps smooth the MACD and identifies buy or sell signals when crossovers occur. One of the primary problems with MACD divergence is that it can frequently signal a possible reversal, but no actual reversal occurs, meaning it produces a false positive. Ultimately, it seems to predict too many reversals that don’t occur and not an adequate amount of actual price reversals. Bullish divergences tend to lead to price reversals, possibly signaling a change in the trend.
What is the basic MACD indicator formula?
The relative strength index (RSI) signals whether an instrument is considered overbought or oversold based on its recent price action. The RSI is an oscillator that calculates the average price gains and losses over a given period. A reading above 70 suggests an overbought condition, while a reading below 30 is considered oversold, with both potentially signaling that a top or a bottom is forming. A divergence ensues when the MACD forms highs or lows that diverge from the corresponding highs and lows in the underlying security’s price. For example, a bullish divergence happens when the MACD forms two rising lows that align with two falling lows on the asset’s price.

Traders often use this value to spot potential reversal points, with levels above 70 indicating overbought conditions and below 30 suggesting oversold conditions. On the other hand, the MACD doesn’t focus on overbought or oversold levels. The MACD (Moving Average Convergence Divergence) is a momentum and trend-following indicator used in technical analysis. So, while the signal crossovers can be helpful, they are not always reliable.
It’s simple and provides a clear snapshot of whether the price is trending up or down. Just as a crossover of the nine- and 14-day SMAs may generate a trading signal for some traders, a crossover of the MACD above or below its signal line may also generate a directional signal. MACD is based on EMAs with more weight placed on the most recent data, which means that it can react very quickly to changes of direction in the current price move. It is not uncommon for investors to use the MACD’s histogram the same way they may use the MACD itself.
How AI Price Predictions Work
Our platform may not offer all the products or services mentioned. Gerald Appel created the MACD in the 1970s to analyze the relationship between two moving averages. This insight allows traders to take short positions or exit long trades. Sometimes it can happen that MACD isn’t a reliable trading signal, and one can’t automatically assume that divergence absolutely confirms it. Double checking, several reverses are preceded by divergence or don’t result in a reversal after all. An approximated MACD can be calculated by subtracting the value of a 26 period Exponential Moving Average (EMA) from a 12 period EMA.
The two lines that are drawn are NOT moving averages of the price. Day traders often use 5-minute or 15-minute charts, while swing traders prefer daily or weekly charts. It signals that bullish momentum is fading and a downward reversal might be imminent. Similarly, confirm the signal by checking for a declining histogram or downward price movement. Traders often interpret this as a good time to enter a long (buy) position. For added confidence, look for confirmation such as an increasing MACD histogram or an upward trend in price action.
As the moving averages get closer to each other, the histogram gets smaller. This is called convergence because the faster moving average (MACD Line) is “converging” or getting closer to the slower moving average (Signal Line). In our example above, the MACD Line is the difference between the 12 and 26-period moving averages. Traders observe changes in the histogram to detect trend weakening before price action confirms it.

It is readily available on most trading platforms offered by top online stock brokers. The difference line, represented in the chart by the blue bars, is typically presented as a bar chart around the zero line. This bar chart represents the difference between the MACD line and the signal line. A narrowing of the difference line (i.e., when the bars decrease) illustrates the potential for a crossover. There isn’t a single “better” indicator than MACD, as effectiveness depends on the trading strategy and market conditions. Some traders prefer other indicators like RSI for momentum or moving averages for trend analysis.
This is because the short-term average will be more responsive to the current market price compared to the long-term average. Thus, a positive value indicates a positive momentum in the stock. A moving average divergence can signal a possible reversal, but it will also produce numerous ‘false positives’ along the way. False positive divergences often occur when the price of an asset moves sideways in a consolidation, such as in a range or triangle pattern. Gerald Appel developed the MACD indicator in the 1970s, and it is still one of the most popular technical tools today.
