"Mastering the Art of Disagreement and Unveiling the Power of Bias in Trading"


Disagreement is a natural part of human interaction, and it plays a crucial role in shaping our understanding of various topics. However, not all forms of disagreement are created equal. In this article, we will explore the different levels of disagreement and how to effectively engage in constructive debate. Additionally, we will delve into the concept of bias in trading and why understanding it correctly is essential for avoiding costly mistakes.

The Stages of Disagreement:

Disagreement can take many forms, ranging from name-calling to well-reasoned refutations. To better understand the nuances of disagreement, let's categorize them into different stages:

DH0: Name-calling: This is the lowest form of disagreement, where individuals resort to personal attacks rather than addressing the substance of an argument. Such responses add no value to the conversation and hinder productive discourse.

DH1: Ad Hominem: While slightly more sophisticated than name-calling, ad hominem attacks still fail to address the core argument. Dismissing someone's viewpoint based on their background or position detracts from the opportunity to engage in meaningful discussion.

DH2: Responding to Tone: Disagreeing with an author's tone rather than their ideas is a weak form of disagreement. Tone should not overshadow the validity of an argument. It is crucial to focus on the substance of the message rather than getting caught up in its delivery.

DH3: Contradiction: Contradiction involves explicitly stating the opposing case without providing substantial evidence or reasoning. While it may highlight alternative perspectives, it often falls short in convincing others due to a lack of substantial support.

DH4: Counterargument: Counterarguments go beyond contradiction by offering reasoning and evidence to support an opposing viewpoint. When aimed directly at the original argument, a well-crafted counterargument can be persuasive. However, it is essential to ensure that the counterargument remains relevant and addresses the central point at hand.

DH5: Refutation: At this stage, disagreement goes beyond presenting counterarguments to the central point. Refutation involves systematically dismantling an argument by providing solid evidence and logical reasoning. It is the hallmark of convincing disagreement.

DH6: Refuting the Central Point: This is the highest form of disagreement, where individuals effectively refute the central point of an argument by providing irrefutable evidence and comprehensive analysis. Engaging in this level of disagreement demonstrates a deep understanding of the topic and contributes to the advancement of knowledge.

Connecting Disagreement and Bias in Trading:

Now that we have explored the stages of disagreement, let's shift our focus to the concept of bias in trading. Bias refers to the repetitive patterns observed in market movements, such as the statistical prevalence of the EUR/USD exchange rate reaching a daily low at 10 am and then rising until 10 pm. Similarly, biases can be observed in other currency pairs or even within specific timeframes.

Renowned trader Gann recognized the presence of biases in trading cycles. He emphasized that within a cycle, there is not just a single division into three or four separate cycles. Instead, he proposed the idea of a four-time cycle containing a three-time cycle within it. Identifying these cycles can be challenging, but Gann's Set Up technique offers valuable insights into this complex phenomenon.

Actionable Advice:

  • 1. Embrace Constructive Disagreement: When engaging in a disagreement, focus on the substance of the argument rather than resorting to personal attacks. Address the central point and provide evidence and logical reasoning to support your position.
  • 2. Seek Different Perspectives: Actively seek out alternative viewpoints to broaden your understanding and challenge your own biases. Consider different arguments and evaluate them based on their merit rather than dismissing them outright.
  • 3. Understand Bias in Trading: Recognize the presence of biases in market movements and incorporate this knowledge into your trading strategy. Utilize techniques like Gann's Set Up to identify and leverage these patterns for more informed decision-making.


Disagreement is an opportunity for growth and learning when approached with respect and intellectual rigor. By understanding the various stages of disagreement and applying constructive techniques, we can foster meaningful discussions and advance our understanding of complex topics. Similarly, comprehending bias in trading allows traders to capitalize on repetitive patterns in market movements. By combining these insights, we can navigate the realms of disagreement and trading with greater confidence and success.
