Journaling 101

The #1 edge that separates profitable traders from the rest. Learn what to track, how to review, and the AI-powered shortcut SPX Plays members use.

What You'll Learn

If you're not reviewing your trades, you're flying blind. Here's exactly what to track and how to review it.

Section 1

Why Most Traders Never Journal (And Why It Kills Them)

Ask any consistently profitable trader what moved them from breakeven to green and almost every answer includes one word: journaling.

And yet, when we survey new SPX Plays members, less than 15% journal their trades consistently. The reason is almost never "I don't believe in it" — it's "I don't have time" or "it's a pain to maintain."

The compound problem

If you take 20 trades a week and 3 are driven by the same unnamed leak (say, revenge trading after a loss), that leak is quietly costing you ~15% of your volume — every single week. A journal is how you name it, so you can kill it.

Without a journal, every trading mistake you make is effectively anonymous. You lose $1,200, you feel bad for 10 minutes, and you move on. The lesson evaporates. The same mistake shows up in different clothes next week.

Section 2

The 9 Fields Every Trade Journal Needs

A great journal is not complicated. It's a simple table that captures the trade and the decision around it. At minimum, every entry should have:

Date / Time

Apr 16 · 10:42 AM

Reveals time-of-day patterns (open volatility, lunch chop, etc.)
Ticker / Contract

SPX 6870P · 0DTE

Spot your best and worst instruments
Entry / Exit Price

2.15 → 4.80

Track slippage and execution quality
Size

5 contracts

Risk management: are you sizing up on bad setups?
P&L

+$1,325

The obvious one — but easy to fudge in your head
Setup / Thesis

GEX flip + double-bottom

Your best setups become your playbook
Plan

Entry 2.10, stop 1.50, target 4.00+

Did you follow it? This is where most leaks live
Emotion / State

Calm · planned trade

Spot FOMO / revenge / overtrade patterns
Lesson

Cut winner early — should've trailed

One sentence. Future-you thanks you.
That's it

Nine fields. If you do this religiously for 30 days, you'll spot your real edge faster than any paid course can teach you.

Section 3

The Mindset Column (The One Most Skip)

The Emotion / State column is the one that separates amateur journals from pro ones. Use a simple tag system — we recommend these six:

  • PLANNED — The trade was in your gameplan before the bell
  • REACTIVE — You saw a setup form and entered in-the-moment (can be good or bad)
  • FOMO — You chased a move that already ran
  • REVENGE — You entered trying to win back a loss
  • OVERTRADE — You'd already hit your daily limit
  • TILT — You were emotionally compromised (stressed, tired, angry)
The insight

At the end of the month, look at your P&L grouped by tag. You'll almost certainly discover that your PLANNED trades are 3-5x more profitable than your REVENGE trades. This single insight is worth more than most traders' entire subscription stacks.

Section 4

How to Do a Proper Weekly Review

Collecting data is half the battle. The other half is sitting down with it. Block 45 minutes every Sunday (same time each week) and answer these four questions:

What was my best trade this week — and why?

Copy the setup into your playbook.

What was my worst trade — and why?

What rule did I break?

Which emotional state made me the most money?

Almost always PLANNED. Scale that.

If I could only fix one thing next week, what would it be?

Write it down. Review it Monday morning.

The one-change rule

Never try to fix more than one leak per week. Your brain can only rewire one habit at a time. Pick the leak that's costing you the most dollars, make the change, and wait until the next review to tackle the next one. This is how professional traders compound improvement.

The Shortcut: TradeDog (50% Off for SPX Plays Members)

Real talk: most traders try manual journaling, do it for 2 weeks, and quit. The friction of remembering every field + importing trades + categorizing them is just too much ongoing effort.

That's exactly why we built TradeDog — an AI-powered trading journal that solves the friction problem:

Log every trade

Manual entry or CSV import from Schwab, Robinhood, Fidelity, E*TRADE, and IBKR. Multi-leg support for scaled entries and exits.

AI Trade Coach

Daily briefings, insight cards, and a chat that answers from your real data. "Stop trading after 2 PM" — specific, not generic.

Psychology tracking

Log emotional state, confidence, and whether you followed your plan. See how your mindset correlates with your P&L.

Frequently Asked Questions

Why is journaling important for trading?

Journaling lets you identify patterns in your trading behavior—both good and bad. Without a journal, mistakes repeat anonymously. With one, you can quantify what's costing you money and fix it systematically.

What's the minimum I need to track in a trading journal?

At minimum: date, time, ticker, entry/exit price, size, P&L, setup/thesis, whether you followed your plan, emotional state, and one-sentence lesson. These 9 fields give you everything you need to improve.

How often should I review my trading journal?

Weekly is ideal. Block 45 minutes every Sunday to review your best trade, worst trade, emotional patterns, and pick ONE thing to fix next week. Monthly reviews are good for spotting longer-term trends.

Can I just use a spreadsheet or do I need TradeDog?

Spreadsheets work—they're better than nothing. But most traders quit after 2 weeks because manual entry is tedious. TradeDog automates the busywork (imports, categorization, analysis) so you actually stick with it. SPX Plays members get 50% off for life.

What if I don't want to relive my losing trades?

That's exactly why most traders stay stuck. Your losses contain your most valuable lessons. The faster you can review them objectively (as data, not personal failure), the faster you improve. Journaling helps you detach emotionally and see the patterns.
