The Principle of Cause and Effect: Building Your Trading Chain of Accountability

Introduction: Chance Is a Word for Law Not Recognized

The sixth Hermetic principle—the Principle of Cause and Effect—states that "Every cause has its effect; every effect has its cause." The Kybalion goes further: "Chance is but a name for law not recognized; there are many planes of causation, but nothing escapes the law."

This principle strikes at the heart of one of the most destructive narratives in trading: the belief that losses are bad luck and wins are good skill. When traders attribute losses to "the market being rigged," "stop hunting by market makers," or simple "bad luck," they are violating the Principle of Cause and Effect. They are assigning randomness to outcomes that have traceable, identifiable causes.

The data supports this forcefully. Analysis across thousands of trading accounts shows a 0.56 correlation between routine completion and trading performance. Traders who complete 70% or more of their pre-trade routine average a gain of $758 per session. Traders who complete less than 70% of their routine average a loss of $113 per session. The difference—$871 per session—is not luck. This is cause and effect, operating with mathematical precision.

The Causal Chain in Trading

Every trading outcome—every win, every loss, every breakeven scratch—is the final link in a chain of causes that extends backward through time. Understanding this chain is the key to improving your results, because you cannot fix an effect without addressing its cause. Treating symptoms without addressing root causes is the single most common failure mode in trading self-improvement.

Consider this common causal chain that produces consistent losses:

Link 1 — Trigger: A large loss on Monday creates emotional frustration and a sense of urgency to recover.

Link 2 — Emotional Response: Frustration activates the amygdala, flooding the body with cortisol and adrenaline. The prefrontal cortex (rational decision-making) is suppressed.

Link 3 — Behavior: The emotional state triggers a need to recover the loss immediately. The trader begins scanning for any setup that might produce a quick gain, abandoning their watchlist and criteria.

Link 4 — Action: The trader increases position size on the next trade to "make it back faster." They enter a marginal setup that does not meet their normal criteria.

Link 5 — Outcome: The oversized position hits the stop, creating a loss that is larger than normal.

Link 6 — Cascade: The now-larger loss intensifies the frustration, and the cycle repeats with even larger sizing and even more desperate entries.

This chain is not random. Each link causes the next. The Principle of Cause and Effect teaches that to break this chain, you must intervene at the earliest possible link—ideally at the trigger level (managing the emotional response to the initial loss) rather than at the action level (trying to use willpower to avoid oversizing while in a state of emotional reactivity). By the time you reach Link 4, the battle is already nearly lost. The intervention must happen at Link 1 or Link 2.

The Routine-Performance Connection

One of the most powerful expressions of cause and effect in trading is the relationship between routine completion and performance. A pre-trade routine typically includes elements like reviewing the daily watchlist, checking economic calendars, performing the mental state assessment, reviewing yesterday's journal entries, and confirming that risk parameters are set.

Each element of the routine serves as a causal link that sets up the conditions for better execution. Reviewing the watchlist ensures you are focused on the best opportunities rather than being distracted by noise. Checking the calendar prevents you from being blindsided by a scheduled news event that turns your carefully planned trade into a coin flip. The mental state assessment catches emotional issues before they affect your trading. Risk parameter confirmation prevents the kind of position sizing errors that turn manageable losses into account-threatening drawdowns.

When traders skip these steps, they remove links from the causal chain that produces positive outcomes. The result is not immediately obvious—you can skip your routine and still have a good day, just as you can drive without a seatbelt and arrive safely. But over a large sample, the data is unambiguous: routine completion causes better performance. The correlation of 0.56 is remarkably strong for a single behavioral variable, and the average difference of $871 per session ($758 gain versus $113 loss) should be enough to make any serious trader treat their routine as non-negotiable.

Moving From Effect to Cause: The Accountability Shift

The Principle of Cause and Effect demands radical accountability. It asks you to stop being an "effect"—someone who is acted upon by the market, by luck, by circumstances—and start being a "cause"—someone who deliberately creates the conditions that produce desired outcomes.

This does not mean that you can control the market or guarantee profits. Individual trades are influenced by factors beyond your control—news events, institutional flows, market maker activity. But you can control the inputs: your routine, your emotional state, your risk management, your entry criteria, your position sizing, and your response to both wins and losses. By controlling the inputs, you optimize the probability of favorable outputs over a large sample of trades.

The shift from "the market took my money" to "I can trace exactly why this trade lost" is the shift from effect to cause. It is the shift from victimhood to agency, from helplessness to empowerment. It is perhaps the single most important psychological transformation a trader can make, and it begins with the simple act of asking: "What caused this?" every single time a trade closes—win or lose.
