FROM THOUGHT TO JOURNAL

Nasdaq · Detailed entry 01 / 03

01 Your voice

0:00Example voice note
I’ve just entered long on the Nasdaq at 21,450. My stop loss is 21,420, and my take profit is 21,510. Price reclaimed the morning high and held the retest. I waited for confirmation instead of chasing. I’m feeling calm, and this matches my breakout playbook.

Your own words, kept alongside the entry.

02 Your journal DRAFT

Your words become a draft here.
You review the details.

Captured mindsetFrom your voice note

Bring the chart you actually reviewed.

Take a photo or choose a screenshot. Attach the view while it is fresh, or come back after saving your entry.

the same attention as your results.

07 / PLAYBOOKS & CHECKLISTS

Your strategy.

A playbook is your personal guide to a trading setup. Give it a name, describe what you look for, and create your own checklist of rules. Then use Jerno to review how consistently you followed them.

Start with the way you trade.

Name your setup and describe what you look for. You create the playbook around your own approach; “London Breakout & Retest” is the custom example shown here.
