The loop begins by observing performance closely enough to make hidden patterns visible. A practitioner records important decisions, the reasoning behind them, relevant emotional or physical conditions, and eventual outcomes. Periodic review then separates behaviors associated with success from those that create trouble. The goal is not merely to count wins and losses, but to discover how decisions were made and whether the process was sound. One recurring pattern is selected for reinforcement or correction, and subsequent entries reveal whether the intervention changes behavior and results. Repeating the cycle turns daily experience into a structured feedback system and reduces dependence on selective memory, intuition, or hindsight.

Core principles
- 01Awareness must precede behavioral change
- 02Record process as well as outcomes
- 03Study successful and unsuccessful patterns
- 04Treat experience as data for continuous learning
How to run it
- 1
Define What to Observe
Choose the decisions, behaviors, emotions, and outcomes most relevant to the performance problem. Keep the scope narrow enough to record consistently.
Pro tip Include process variables such as timing, preparation, mood, and energy rather than tracking profit alone.
Watch out Tracking too many variables can make the journal unsustainable.
- 2
Record Decisions Daily
Document what you decided, how and why you decided it, and what happened afterward. Capture observations while the reasoning is still fresh.
Pro tip Use the same short template for every entry.
Watch out Do not rewrite your original reasoning after seeing the outcome.
- 3
Review for Patterns
Compare entries to identify behaviors that accompany strong and weak performance. Look for repeated conditions rather than isolated events.
Pro tip Review both winning and losing decisions for process quality.
Watch out A small number of outcomes may reflect luck rather than a stable pattern.
- 4
Choose One Adjustment
Select one successful pattern to repeat or one harmful pattern to interrupt. Define the adjustment as an observable behavior.
Pro tip Favor incremental changes that can be tested quickly.
Watch out Trying to correct several patterns simultaneously obscures what caused improvement.
- 5
Measure the Change
Continue journaling and compare later entries with the baseline. Retain, refine, or replace the adjustment based on evidence.
Pro tip Evaluate behavioral consistency before judging financial results.
Watch out Do not abandon a sound process solely because of a short run of bad luck.
In the wild
A trader records every trade, its rationale, mood, and market conditions for three weeks. Review shows that most low-quality trades occur after an early loss, when the trader feels urgency to recover. The trader introduces a mandatory ten-minute pause after losses and tracks compliance in the same journal.
→ Reactive trades decline and decision quality becomes more consistent.
An investor believes most stock selections are successful but records position size and realized gain or loss. The journal reveals that frequent small winners are outweighed by a few oversized losses. The investor adds explicit loss limits and position-size reviews.
→ The investor corrects a risk-management flaw that win-rate memories had concealed.
Common mistakes
Tracking Outcomes Only
Profit and loss show what happened but not whether the decision process was repeatable or sound.
Using the Journal as a Diary
Unstructured reflection may feel useful without producing comparable observations or actionable patterns.
Changing From One Result
A single win or loss can be random, so adjustments should be based on recurring evidence.
Is it for you?
Best for
It is best for traders and other professionals who make repeated decisions under pressure.
Not ideal for
It is not ideal for people unwilling to document decisions honestly or review their own mistakes.
From the transcript
“The process begins with self observation, and this is true of any psychological change. We have to become aware of our patterns before we can…”
“the most basic exercise that people associate with coaching of traders would be keeping a journal”
“it's astonishing how much can be learned by keeping score and tracking the various elements of your trades and your decision making.”
