Journal craft: how I teach it to a mentee
Posted: Sun Oct 04, 2026 5:49 pm
Teaching someone to keep a trading journal turned out to be harder than teaching them a setup. The setup is concrete. The journal is a habit, and habits are hard to hand over.
I've mentored three traders over the years, and with the most recent one I finally found an approach that worked. It's built in stages, over about six weeks.
Weeks one and two: only facts. Time, pair, direction, entry, stop, exit, result in R. Nothing else. The goal is to make the habit automatic before adding anything that requires thought. If she missed a trade, we discussed why it wasn't logged, not what the trade was.
Weeks three and four: add one line of reason for each entry, written before the trade. Not after. This is where most people struggle, because writing before the trade forces you to have a reason.
Weeks five and six: add one line after each exit, answering only "did I follow the plan, yes or no, and if no, what was different?" No emotional essays.
From then on, a weekly review. Thirty minutes on Sunday, where she reads back the week and picks the single most common rule break. Just one. That becomes the focus for the next week.
What didn't work with the earlier mentees: giving them my full journal template on day one. It had 22 columns. They both gave up within a month.
Start small, add slowly, and keep the weekly review short. That's most of it.
