The MACD Indicator


One trading tool that has gained a reputation for its efficacy is the Moving Average Convergence Divergence (MACD) indicator. Developed by Gerald Appel in the late 1970s, MACD is a versatile indicator, and in this blog post, we’re going to take a deep dive into it, so you can understand its components, interpret its signals, and make it an integral part of your trading strategy.

Getting Cosy with MACD: The Basics

Imagine MACD as a good book with three main characters: the 12-period Exponential Moving Average (EMA), the 26-period EMA, and the 9-day EMA of the MACD itself. These characters interact in a way that tells us a compelling story about a stock’s price movement.

The 12-period EMA

It is like the eager adventurer, it represents a shorter-term moving average of a stock’s price. It’s called “exponential” because it gives more weight to recent prices, making it responsive to short-term price changes, quick to respond to price movements and more sensitive to recent developments in the stock’s price.

The 26-period EMA

It is, in contrast, the seasoned traveller, it represents a longer-term moving average. It’s more stable and less responsive to short-term price fluctuations. The 26-period EMA smoothens out the price data and provides a broader perspective on the stock’s trend. It’s not as easily swayed by short-term volatility. The MACD line is the result of subtracting the 26-period EMA (the seasoned traveller) from the 12-period EMA (the eager adventurer). It’s the dynamic blend of these two moving averages. The MACD line’s movements tell a story of how the shorter-term and longer-term trends in a stock’s price are interacting. When it crosses above or below the “signal line,” it generates signals about potential changes in the stock’s trend direction. It’s like the child of our characters, embodying the essence of both the adventurer and the traveller.

The 9-day EMA

But what adds more depth to the story is the “signal line,” a 9-day EMA of the MACD. It acts as a smoother, providing further context to the story told by the MACD line. When the MACD line crosses above or below the signal line, it can serve as a trigger for buy or sell signals. It’s like the wise mentor in the story, offering guidance based on the experiences of the adventurer and the traveller, as represented by the MACD line.

MACD Signals: The Language of Trading

Now, let’s decipher the signals this story tells:

  1. The Crossing of MACD and Signal Line: This is the heart of the narrative. When the MACD line crosses above the signal line, it’s as if the adventurer finally catches up with the seasoned traveler, and the story gets exciting. It’s a signal that it might be a good time to buy, indicating a bullish trend. Conversely, when the MACD line crosses below the signal line, it’s like the seasoned traveler taking the lead, and the story turns darker. This signals a potential selling opportunity, as it indicates a bearish trend.
  2. MACD Line vs. Zero Line: Think of the zero line as a pivotal plot twist. When the MACD line crosses above it, it’s a signal that the adventurers are conquering new peaks, suggesting an uptrend. But if the MACD line takes a plunge below the zero line, it’s like they hit an obstacle. This indicates a potential downtrend.
  3. Divergence: The Plot Thickens: Divergence in MACD is akin to a subplot that reveals hidden truths. Bullish divergence happens when the price makes a lower low, but the MACD forms a higher low. It’s like finding a treasure map; it suggests potential upward momentum. On the other hand, bearish divergence occurs when the price makes a higher high, but the MACD forms a lower high. It’s a warning sign, indicating possible downward momentum.
