The Retrace principle

You don’t need to predict the market.

Just honestly record what you believed at the time.

How Retrace works

One decision. Three honest steps.

Retrace keeps the process deliberately simple, so your original reasoning stays clear when it is time to look back.

Record the decision

Write down the asset, your core thesis, the risks, and your state of mind before hindsight rewrites the story.

Original thesisAI infrastructure demand remains durable

Review on schedule

Return on the date you chose and judge each thesis: strengthened, stable, weakened, or falsified.

Build insight

See which decision patterns keep returning—without turning reflection into another opaque score.

Pattern surfacedReviews are on time; risk notes need depth

A journal preserves what happened. Retrace preserves what you believed—and shows how that belief changed.

Review without hindsight bias

Return to the reason, not just the result.

Retrace brings back your original words and asks one focused question at a time. The market outcome never gets to rewrite the thesis for you.

Review each thesis separatelyKeep a strong reason from hiding a weak one.
Add context when something breaksCapture what weakened a thesis or triggered a risk.
Keep a decision trailEvery conclusion becomes part of the history, not a replacement for it.

Insight from repetition

See the patterns behind your judgment.

A single trade tells a story. Repeated reviews reveal habits: whether you review on time, which theses weaken, and where your process needs attention.

Explainable by design

Every trend points back to the reviews and decisions that created it.

Privacy by design

Your decisions stay yours.

Investment reasoning is deeply personal. Retrace is built so your core records remain under your control—not on an analytics dashboard we can inspect.

Make every decision worth revisiting

Clarity begins before the outcome.

Record what you believe today. Return with evidence tomorrow. Build a process you can trust over time.
