If you’ve been trading for any length of time, someone has told you to keep a trading journal. The advice is universal — from Reddit threads to professional mentorship programs to prop firm training materials.

But nobody tells you exactly what that means in practice. What should you actually write down? How often? What do you do with the data once you have it? And at what point does a spreadsheet stop being enough?

This guide answers all of those questions, from first trade entry to full behavioral analytics.

Why Keep a Trading Journal at All?

Let’s start with why this matters, using a specific example.

Imagine you’ve been trading for 3 months. You’re breakeven overall — some winning weeks, some losing weeks. You feel like you’re making progress but can’t quite prove it.

Without a journal, here’s what you know:
- Your account balance (up or down from starting point)
- A vague sense of “I do better in the morning”
- Some trades you remember being particularly good or bad

With a journal, here’s what you can know:
- Your exact win rate, average win, average loss, and expectancy
- Which hours of the day are profitable and which aren’t
- Which symbols make you money and which drain your account
- Whether your revenge trading habit is getting better or worse
- How much trading fees are eating into your profits
- Whether your average hold time has changed

The difference is the gap between feeling and knowing. Feelings change with your mood. Data doesn’t.

What to Track: The Minimum Viable Journal

You don’t need to track 50 fields per trade. Start with the essentials:

Required Fields

Field Why It Matters
Date/Time Identifies when you trade best/worst
Symbol Shows which instruments are profitable
Side (Long/Short) Reveals directional bias
Entry Price Needed for P&L calculation
Exit Price Needed for P&L calculation
Size/Quantity Shows position sizing patterns
P&L The bottom line
Fees Often ignored, often significant

Recommended Fields (Add When Ready)

Field Why It Matters
Setup Type Identifies which setups work
Hold Time Reveals patience vs impulsive patterns
Notes Context that data alone can’t capture
Emotional State Correlates mood with performance
Screenshot Visual record of the trade setup

Fields You DON’T Need Yet

Don’t overcomplicate your journal with fields you won’t use consistently:
- Market conditions (until you can classify them systematically)
- Detailed technical analysis notes (unless you have a structured checklist)
- Fundamental analysis (unless it’s part of your strategy)

The goal is consistent, complete entries — not comprehensive but sporadic ones.

Three Ways to Keep a Trading Journal

Option 1: Spreadsheet (Free, Manual)

The simplest approach. Create a Google Sheet or Excel file with columns for each field.
