Moving Average Convergence Divergence MACD: Definition
Or the MACD line has to be both negative and crossed below the signal line for a bearish signal. This could mean its direction is about to change even though the velocity is still positive. This would be the equivalent to a signal line crossover but with the MACD line still being positive. While zero crossovers may indicate a change in the direction of a trend, traders generally place more on a signal line crossover, as a zero crossover provides no indication in itself in the trend’s rate of change. Another MACD drawback is its inability to make comparisons between different securities.
Crossovers
- The Moving Average Convergence Divergence triggers technical signals when the MACD line crosses above the signal line (to buy) or falls below it (to sell).
- One reason traders frequently lose with this setup is that they enter a position on a signal from the MACD but exit it based on the movement in price.
- The height and width of the positive bars can provide information about the strength of the upward momentum.
- Conversely, a possible downtrend is indicated when the MACD line falls below the signal line.
If price is making a high while the MACD line is declining (called “negative divergence” or “bearish divergence”), this could indicate that price could fall. If price is making a new low while the MACD line is increasing (called “positive divergence” or “bullish divergence”), this could indicate that price could rise. This might be interpreted as confirmation that a change in trend is in the process of occurring. For example, Bullish Divergence occurs when price records a lower low, but the MACD records a higher low. The movement of price can provide evidence of the current trend, however changes in momentum as evidenced by the MACD can sometimes precede a significant reversal. Another common signal that many traders watch for occurs when the indicator travels in the opposite direction of the asset, something known as divergence.
It means the trend in the stock – its magnitude and/or momentum – is starting to shift course. When the MACD(12,26) crosses above the EMA-9, this is considered a bullish signal. Traders should be aware that the whipsaw effect can be severe in both trending and range-bound markets because relatively small movements can cause the indicator to change directions quickly. A large number of false signals can result in a trader taking many losses. When commissions are factored into the equation, this strategy can become very expensive. The MACD is calculated by subtracting the longer-term exponential moving average (EMA) from the shorter-term EMA.
A potential uptrend for Bitcoin may be signaled when the MACD line surpasses the signal line. Conversely, a possible downtrend is indicated when the MACD storing bitcoins in a wallet line falls below the signal line. 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.
Is MACD a Leading Indicator or a Lagging Indicator?
It has become standard to plot a separate moving average alongside the MACD, which is used to create a clear signal of shifting momentum. A signal line, also known as the trigger line, is created by taking a nine-period moving average of the MACD. As you can see in the figure below, transaction signals are generated when the MACD line (the blue line) crosses through the signal line (nine-period EMA – orange line).
For example, consider a stock with a falling price and an MACD that is growing more negative, indicating downside momentum. The same divergence indication can be applied to a stock that is gaining in price but losing upside momentum. When MACD forms a series of two falling highs that correspond with two rising highs on the price, a bearish divergence has been formed. A bearish divergence that appears during a long-term bearish trend is considered confirmation that the trend is likely to continue. The exponential moving average is an exponentially weighted moving average. An exponentially weighted moving average tends to have more significant reactions to recent price changes than a simple moving average (SMA).
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. The MACD histogram illustrates the difference between MACD and the signal line. The histogram is made of a bar graph, making it visually easier to read and interpret. 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. J.B.

The variable c represents the time period of the EMA taken of the MACD series above.

RSI plots the current price relative to recent price highs and lows. MACD is better for identifying trend direction while RSI helps determine overbought/oversold levels. The MACD is most useful when there is a trend underway that you want to trade in the direction of. When prices are trending higher, watch for the MACD line to crossover above the signal line and turn positive. how to buy superfarm This suggests upside momentum is building and provides a buy signal to trade the uptrend. Conversely, when prices are in a downtrend, a crossover below the signal line and MACD turning negative hints downside momentum is accelerating.
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. 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. A crossover of the centerline can be analyzed similarly, but without the consideration of short-term momentum provided by the lagging signal line. The MACD crossing from negative to positive territory indicates that a stock’s price is gaining momentum in the upward direction, while the opposite crossover indicates that the price is gaining downside momentum. When MACD forms highs or lows that exceed the corresponding highs and lows in the instrument’s price, it is called a divergence. A bullish divergence appears when MACD forms two rising lows that correspond with two falling lows on the how to buy alt coins price.
But if you’re too conservative then you’ll never end up taking trades altogether. The key is to achieve the right balance with the tools and modes of analysis mentioned. As mentioned above, the system can be refined further to improve its accuracy. This may involve the inclusion of other indicators, candlestick and chart pattern analysis, support and resistance levels, and fundamental analysis of the market being traded. Though collectively there would have been a little bit of profit made following the standard signal line crossover strategy from the MACD(12,26,9) settings, this strategy is too naïve to make an entire system around.
