Trading Is Like Playing Chess At Scale

Welcome to the strategic battleground of Forex trading, where every move is like a chess math, and game theory is your secret playbook. Trading is a game, and Game Theory is why it all works. 

What is Game Theory?

Game theory is a branch of mathematics and economics that studies decision-making in situations where the outcome depends not only on one's own decisions but also on the decisions of others. It explores the strategies individuals or groups adopt in different scenarios, particularly in situations of conflict or cooperation. 

It’s widely used in various fields such as economics, political science, biology, and computer science, to understand and predict rational behavior in interactive situations. Classic examples include the Prisoner's Dilemma and the Nash Equilibrium, demonstrating how individuals may choose strategies based on the anticipated decisions of others.

Understanding the Players

In Forex, like in a game of poker, understanding your opponents - in this case, market participants - is crucial. Central banks, institutional investors, and retail traders, each with their strategies, create a dynamic and competitive environment. Imagine a poker table where each player's bet influences the others' strategies. If everyone always played the same it would be predictable and therefore anyone who played outside the norm would have an advantage and could abuse the predictability of others. 

The Prisoner’s Dilemma in Forex

One classic game theory concept is the Prisoner's Dilemma, where two individuals might not cooperate, even if it’s in their best interest.

The Prisoner's Dilemma is a fundamental problem in game theory that demonstrates why two rational individuals might not cooperate, even if it appears that it's in their best interest to do so. In this scenario, two prisoners are suspected of committing a crime together. They are interrogated separately and given the choice to betray the other or to remain silent. The dilemma arises because each prisoner must choose between cooperation (remaining silent) and betrayal, without knowing what the other will choose. 

The optimal decision would be to remain silent. However, they will likely assume the other will throw them under the bus. Therefore to protect themselves they betray their accomplice. This individually leads to a worse outcome for both, compared to if they had cooperated. This dilemma illustrates the conflicts between individual and collective rationality.

Using game theory in the context of price action in Forex trading involves anticipating how other market participants will react to price movements. By understanding common patterns and traders' likely responses to these patterns, you can strategize your trades accordingly. 

For example, if a currency pair is approaching a well-known resistance level, game theory would have you consider not just your own potential action (like taking a short position), but also how other traders are likely to react at this level. This anticipation of collective behavior can inform whether to enter, exit, or wait for a more favorable trading opportunity.

For instance, consider a scenario where the EUR/USD pair is on an uptrend and approaches a known resistance level. Traders watching this pattern might anticipate a reversal at this point. If you're employing game theory, you wouldn't just consider your own action (which might be to hold and hope for a breakout), but also anticipate that many other traders are likely to see a reversal at this level. If you’re in a lot of profit on this trade, you might consider exiting the trade at the resistance level. 

If a significant number of traders act on this expectation and start selling, their collective action could indeed cause the price to reverse, fulfilling the forecasted pattern. This is a classic example of a self-fulfilling prophecy in trading, where traders' anticipation of a pattern contributes to making it happen. 

The Fibonacci levels for example only ever work because of this principle. There is nothing special about the numbers but enough traders believe it to be so, that it creates a self-fulfilling prophecy. 

Zero-Sum Game: The Forex Reality

Forex trading is what’s known as a zero-sum game, where one trader’s gain is another's loss, much like in a game of chess. Every move you make on the currency board impacts and is impacted by other players' moves. This is an important principle to remember. When you win, it means someone else has to lose. 

Forex is Just Online Poker

In the context of game theory, both poker and Forex trading involve strategic decision-making where success hinges on predicting and reacting to the actions of others.

 Players in both fields must evaluate the likely strategies of their opponents or market participants and adjust their actions accordingly. 

In poker, this might mean bluffing or folding based on the perceived strength of other players' hands.

A good trading example for instance is one that I imply on the NASDAQ. The Bias in the NASDAQ is always to the upside. Knowing this, I tend to take way more long trades at the market open than I do short trades. A famous trader once told me “If the long-term trend of the NASDAQ is bullish, and 60% of your trades are shorts… you’re an idiot”. Well, he’s right!

Game theory in Forex is about understanding that every trade is a move on the global currency chessboard. Remember, trading is just a game on an extremely large scale. If you want to win, you need to beat others. Learn to play the game and become the best at it.

STOIC QUOTE OF THE DAY

This quote emphasizes the Stoic belief in the value of adversity and challenges in personal growth. It suggests that just as a gem requires friction to shine, a person needs to face and overcome difficulties to reach their full potential. This reflects the Stoic view that trials and hardships are opportunities for self-improvement and character development.
