The Odyssey has been passed down for nearly three thousand years, and many of the issues discussed within it remain relevant today: strategy, temptation, risk, adaptation, and perseverance. Christopher Nolan's film adaptation has become one of the most anticipated movie projects of 2026, bringing these ancient themes back into the public eye. For traders, they also have a very realistic aspect.

The Odysseus described by Homer is not the strongest hero, yet he ultimately completes the ten-year journey home. He cannot control the sea or the gods, and he cannot guarantee that his crew will always make the right choices. What he can do is think ahead about what to do next, stick to his principles, and adjust in a timely manner as situations change.

Trading is much the same. The market will not operate according to your plan; what can truly be mastered is how to formulate strategy, control risk, and respond after market conditions change.

Let’s explore the five themes of the Odyssey and see their similarities to real trading.

First, a table to align these five themes with corresponding behaviors in trading.

The Most Familiar Themes of the Odyssey

From a literary perspective, the most commonly discussed themes of the Odyssey include wisdom and strategy, perseverance, temptation, loyalty, identity and disguise, hospitality, returning home, and the relationship between fate and personal choice. This epic spans 24 books, narrating Odysseus's ten-year journey home from Troy. However, the truly detailed stories in the poem focus mainly on the last few weeks of the journey.

Rather than listing these themes one by one, it's more noteworthy how the work shapes the character of Odysseus.

The core character of the Iliad, Achilles, is famous for his strength in direct battle, while the protagonist of the Odyssey is referred to by Homer as polytropos, meaning someone skilled in adapting and resourceful. What Odysseus excels at is making judgments based on the situation.

The goddess Athena, symbolizing wisdom and strategy, particularly favors him. In Ancient Greek, there is also a word called metis, which roughly refers to practical wisdom, enabling one to observe the situation flexibly and find solutions despite being unable to alter external conditions.

The following themes all embody this ability.

This is also why traders reading the Odyssey often gain insights that differ from a typical literary classroom experience. The market does not reward you simply for being brave. What truly matters is whether you can still make reasonable judgments and carry them out when conditions and environments are beyond your control.

The following five themes can further translate into specific trading principles.

Theme One: Strategy Over Brawn

Among the various themes in the Odyssey, strategy is perhaps the easiest to correspond directly with trading.

When Odysseus is trapped in the cave of the Cyclops Polyphemus, he quickly understands two realities. First, he cannot defeat this giant in a face-to-face battle. Second, even if he kills him, they will still be trapped in the cave because the massive stone at the entrance cannot be moved by anyone.

Therefore, he devises an entire escape plan: first, he uses wine to relax the giant, then tells him a false name, next he blinds him, and finally, he has his crew hide beneath the sheep to escape. The Trojan Horse mentioned in Book 8 of the Odyssey is fundamentally the same idea, just on a larger scale.

The strategy here refers to knowing what to do in advance for different situations. This is precisely the distinction between market opinions and executable strategies.

"Bitcoin seems strong" is just a judgment. A true strategy must answer more questions: under what conditions to enter, what size of position, what situations represent a failed judgment, when to exit, and what to do if the price suddenly reverses after entering.

More trading does not equate to better trading, and this has been substantiated by research. A study published in the Journal of Finance, covering 66,465 brokerage accounts, found that the most active investors achieved an annual return of only 11.4%, while the market return during the same period reached 17.9%. Frequent trading did not lead to better outcomes but increased costs. Researchers believe the primary reason is overconfidence, which is not significantly related to the quality of information.

Traders easily mistake doing more for having more of an advantage. Many people often only realize this much later but have been paying the tuition for it from early on.

Writing rules out in advance may transform judgments and efforts into a repeatable process.

Theme Two: The Sirens and Pre-set Rules

Among the themes of the Odyssey, self-control may be the most easily misunderstood.

Odysseus does not intend to resist the Sirens' song with willpower. On the contrary, he assumes from the very start that he will be unable to withstand temptation.

Before the ship enters the range of the Sirens' song, he first blocks his crew's ears with beeswax, then has them tie him securely to the mast, and gives an order beforehand that even if he pleads to be untied later, they must only tighten the ropes.

In the end, he hears the Sirens' song and survives because the truly important decision was made well before the temptation arose.

Behavioral economics has even directly borrowed this story. Limiting one's future self in advance is called a Ulysses contract, referring to the "Ulysses contract." Broader research on commitment mechanisms discusses how to pre-set constraints to reduce the chances of changing decisions in the moment of temptation. Jon Elster's book Ulysses and the Sirens, published in 1979, systematically discusses this concept.

Its core principle is to turn off certain options in advance so that willpower does not have to be tested at the moment temptation appears.

In trading, the Sirens might represent a sudden large bullish candle right after you’ve just sold, a drop that looks "certainly bottomed out" after a slump, or a position that is already losing but makes you think, "a bit more margin will help it come back."

Setting rules and discipline in advance is usually more effective than reminding yourself to stay calm after emotions rise. Setting TP/SL, controlling individual positions, setting limits for daily losses, and using gradual margin requirements when necessary can help keep possible losses from a trade within an acceptable range.

This behavioral pattern can also be observed in the real market. A BIS study on cryptocurrency trading platforms found that after the collapses of Terra and FTX, smaller retail investors were increasing their buying, while larger investors were selling. During significant market shocks, people are more likely to make similar decisions driven by emotions.

Of all the themes in the Odyssey, this is perhaps the easiest one to write directly into trading rules.

Theme Three: Scylla, Charybdis, and the Risks You Can Bear

If there is one theme in the Odyssey that shows no mercy, it is risk.

Circe gave Odysseus a choice that has no perfect answer. Sailing close to Scylla would result in losing six crew members; sailing close to Charybdis could result in losing the entire ship.

Ultimately, Odysseus chooses to accept a loss that he can bear and then continues onward.

The choice of risk in trading is essentially similar. What is worth calculating is which kind of loss occurs after which the account can still continue trading the next day.

The mathematics of drawdowns explain very well why this is so crucial, because losses and recovery are never symmetric.

Moreover, as losses grow, the difficulty of recovering increases.

A 20% drawdown may mean only that an investor has experienced a very bad month. A 70% drawdown is already a completely different issue because the remaining funds must increase more than three times to return to breakeven.

Liquidation is a "Charybdis-style" outcome. It not only ends that position but also directly deprives you of the opportunity to continue waiting for the judgment to be validated. Even if later the market moves in your direction, it is already irrelevant to you.

Therefore, a fundamental principle of risk management is to first avoid losses that you cannot bear and then consider how much you can earn.

What position management truly decides is how much space remains for staying in the market after making a wrong judgment.

Theme Four: Adapting to Change is More Important than Pursuing a Perfect Plan

Among the various themes in the Odyssey, adapting to change may be the most challenging task once positions are held.

The challenges throughout the epic almost never repeat. Dealing with the Cyclops requires deception and strategy. With Circe, one needs antidotes and negotiation. Entering the underworld requires following specific rituals. Facing the suitors requires patience and disguise.

If Odysseus were to use the same method regardless of the situation he encountered, he would likely struggle to reach the end of his journey.

The market is similar.

A strategy that works well in a trending market may lead to continuous losses in a choppy market. A mean-reversion strategy that is effective in a low-volatility environment may fail completely after volatility suddenly increases. Funding rates, market liquidity, and inter-asset correlations are all subject to change, thus a set of identical rules applied to different market conditions will yield different returns and risks.

The more challenging aspect is admitting one's mistakes.

Many traders will prematurely sell profitable positions because realizing gains provides a sense of certainty that "this judgment was right." Conversely, faced with losing positions, they are more likely to continuously extend holding durations and reframe what was initially intended as a short-term trade into a "long-term bullish" position. Over time, what remains in the account may be predominantly positions already rejected by the market.

However, it is essential to distinguish between two things.

If the market conditions upon which a strategy originally relied have changed, then adjusting the strategy counts as adapting to the market. But if one immediately overturns an entire method after losing twice in succession, that is another matter altogether.

To determine whether it is "the strategy truly needs adjustment" or "it’s just normal short-term volatility," one requires enough trading samples for the data to be genuinely meaningful.

Theme Five: The True Report Card is the Whole Journey

Perseverance is the last theme of the Odyssey discussed in this text. In Book 10, there is a very typical story.

The wind god Aeolus gives Odysseus a bag containing all the contrary winds. The ship sails smoothly and is nearing Ithaca, even able to see the lights on shore. Just at that moment, the crew, believing the bag contains treasure, opens it without permission.

The violent winds instantly blow them all the way back to square one.

A single trade, after all, is difficult to delineate much about.

A profitable trade cannot prove that a strategy is effective, nor can a loss demonstrate its ineffectiveness. What has real reference value is the overall performance within a sample of trades, including the yield over a certain period, maximum drawdown, recovery time, the ratio of average profits to average losses, and how the strategy performs after market conditions change.

Time-weighted returns and net value curves can display this complete process, whereas a screenshot of a single profitable trade cannot.

If we break down Odysseus’s journey, he actually experiences numerous failures. He loses ships, loses crew, and spends ten years.

Yet, from the narrative of the entire story, he ultimately is the one who successfully returns home and safeguards what he intended to protect.

The Odyssey truly emphasizes this longer time scale. The market is the same.

When Trading Discipline Becomes a System

The five stories presented before ultimately point to the same issue. Knowing what to do is one thing; whether one can consistently do it in a real market is another.

A strategy can pre-define entry, stop loss, position size, and exit conditions, but upon entering the market, traders still face drawdowns, consecutive losses, sudden market movements, and the impulsive emotions driven by fear and greed. Often, the strategy itself does not change; what changes is the person executing the strategy.

There are similar scenarios in the Odyssey.

On the island of Helios, the rules are clear, and everyone knows not to touch the cattle on the island. However, after Odysseus falls asleep, the hunger-driven and unrestrained crew ultimately breaks these rules. In the end, none of these crew members survive to complete their journey.

A trader may strictly follow the rules for 30 trades, but when it comes to the 31st trade, they may decide to move their stop loss backward because they see an "obviously great opportunity" at two in the morning.

The real issue does not lie in this single deviation; it is that it may gradually become a habit. By that point, the results of subsequent trades are likely no longer representative of the initially designed strategy, as what is truly executed is now a method continuously modified temporarily, with inconsistent execution standards.

Therefore, strategy addresses what should be done, while discipline determines whether one can consistently execute it.

When the number of trades increases from a few to dozens, hundreds, execution consistency itself becomes part of the trading system. This is also one of the reasons why algorithmic trading, rule-based strategies, and automated execution tools have long been prevalent. They initially solve not the prediction issue but the execution issue, allowing pre-set entry, exit, and risk rules to operate as similarly as possible, minimizing the changes in plans due to varying emotional states.

However, more stable execution does not mean that the strategy itself is more effective.

Systematic execution can minimize the deviations in the execution process, but it cannot resolve the uncertainty inherent in the market. As for whether a strategy truly has advantages, can withstand drawdowns, and remain effective after the market environment changes, it will ultimately depend on longer-term actual performance for judgment.

Back to the Sea

The market resembles the sea in the Odyssey; it will not run in the expected direction just because a trader has made plans.

The controllable aspects always remain limited; what traders can truly control are a few things: how to judge, how much risk they are willing to bear, and what they are prepared to do upon realizing a judgment error.

A reliable trading system's purpose is not to ensure that one is always right, but to keep errors within an acceptable range.

This may also be the most practical lesson the Odyssey offers today's traders.

When Odysseus finally returns to Ithaca, the ship is gone, and none of his fellow crew have returned. But he ultimately returns to his homeland and completes the last battle of this decade-long journey with the bow that only he can draw.
