“Momentum, Direction, and Divergence” by William Blau is a seminal work in the field of technical analysis, offering traders and financial analysts a robust framework for understanding market momentum. In this book, Blau introduces unique indicators that help in identifying trends, market strength, and potential reversals. The text is a blend of theoretical foundations and practical applications, making it an essential resource for anyone interested in improving their trading strategies. The book’s emphasis on momentum, direction, and divergence provides readers with tools to navigate the complexities of financial markets effectively.

Blau begins by exploring the concept of momentum, a critical element in financial markets that reflects the rate of change in a security’s price. He introduces the formula for calculating momentum and discusses its significance in determining market trends. Blau’s approach to momentum is grounded in the belief that understanding the speed of price movement is crucial for anticipating future market behavior.

One of the key examples Blau uses to illustrate the concept of momentum is the comparison between two stocks: one with a steady, slow upward trend and another with sharp, rapid movements. He explains that while both may have similar price increases over time, the latter exhibits higher momentum, indicating potential volatility and risk.

“Momentum is the life force of the market, a pulse that, when properly measured, can reveal the market’s true intentions.”

In the next section, Blau delves into the importance of direction in trading. He introduces directional indicators, such as the Directional Movement Index (DMI) and Average Directional Index (ADX), which are tools designed to help traders assess the strength of a trend. Blau explains that understanding the direction of a market is crucial for making informed trading decisions, as it allows traders to align their strategies with the prevailing market trend.

Blau provides a case study of a trader who ignored the direction of the market, focusing instead on price alone. The trader’s failure to recognize a strong bearish trend led to significant losses. Blau uses this example to underscore the importance of incorporating directional indicators into trading strategies.

“To trade against the trend is to fight a losing battle; direction is the compass that guides successful traders through the turbulent waters of the market.”

One of the most valuable concepts Blau introduces in this book is divergence, which occurs when the price of a security moves in the opposite direction of an indicator. Divergence is often a precursor to a market reversal, making it a critical tool for traders. Blau explains the different types of divergence—regular and hidden—and how they can signal either the continuation or reversal of a trend.

Blau uses the example of a bullish divergence, where the price of a stock is falling, but the momentum indicator is rising. This divergence suggests that the downward trend is losing strength, potentially signaling a reversal. Conversely, a bearish divergence, where the price is rising but the momentum indicator is falling, can indicate that the upward trend is weakening.

“Divergence is the market’s way of whispering a warning; only those attuned to its subtleties will hear and act before the rest.”

Blau’s book is not just about theory; it is rich with practical applications that traders can implement in their strategies. He introduces several proprietary indicators, including the True Strength Index (TSI), which he developed to provide a more accurate measure of momentum by filtering out price fluctuations that can cause false signals.

Blau demonstrates the effectiveness of the TSI through a detailed analysis of historical market data. He shows how this indicator, when combined with other tools like the ADX, can help traders identify optimal entry and exit points. The book provides several examples of how these indicators can be applied to different markets, from stocks to commodities.

An example Blau discusses is the application of the TSI during a period of market consolidation. While other indicators may give mixed signals, the TSI can offer a clearer picture by filtering out the noise, allowing traders to make more informed decisions.

As the book progresses, Blau delves into more advanced techniques, combining the concepts of momentum, direction, and divergence to create a comprehensive trading strategy. He explains that while each of these elements is powerful on its own, their true potential is realized when used together.

Blau illustrates this with an example of a trader who uses momentum to identify a strong upward trend, direction to confirm the trend’s strength, and divergence to anticipate the point at which the trend might reverse. By integrating these indicators, the trader is able to maximize profits while minimizing risks.
