Trading Journal

Every professional in every field tracks their performance. Athletes watch game film. Surgeons review cases. Musicians record rehearsals. Yet most traders never write down why they entered a trade, how they managed it, or what they learned. A trading journal is the single most underused tool for improvement.

What to Log for Every Trade

At minimum, record these fields for every trade:

Entry details:

Date and time opened
Underlying and current price
Strategy (bull put spread, iron condor, etc.)
Strike prices and expiration
Number of contracts
Credit or debit
IVR/IVP at entry
Why you entered (your thesis in 1-2 sentences)

Management details:

Adjustments made (date, what you did, why)
Date and time closed
Closing price
P&L (dollars and percentage)
Days in trade

Post-trade analysis:

Did you follow your entry rules? (Yes/No)
Did you follow your management rules? (Yes/No)
What would you do differently?

A Real Journal Entry

Date: March 5, 2026 Underlying: AAPL at $192 Strategy: Bull put spread Strikes: $180/$175 put spread, 42 DTE Contracts: 3 Credit: $1.15 per spread ($345 total) IVR: 62 (elevated) Thesis: AAPL above 50-day MA at $185, support at $180 from prior consolidation. High IVR favors credit strategy.

March 15: AAPL dropped to $186. Spread at $1.90. Thesis intact — $180 support holding. No action.

March 21: AAPL at $189. Spread at $0.58 (50% of max profit). Closed for $0.57. P&L: +$174 total.

Process score: 4/4 (followed entry criteria, sized correctly, managed at 50%, exited on target)

Notes: Good trade. Considered holding to 75% but the 50% rule is the 50% rule. Stock ended up at $193 by expiration — would have been max profit. Still the right decision based on process.

Why Screenshots Matter

A chart screenshot captures what you saw when you entered. Three months later, you will not remember what the chart looked like. But when you review your journal, that screenshot tells the story: "I entered because the stock was bouncing off the 50-day MA with rising volume."

Take screenshots at entry, at adjustment points, and at exit. Free tools like Greenshot or the built-in screenshot tool on any OS make this a 5-second habit.

Weekly Review (30 Minutes)

Every Sunday, review the past week:

How many trades did I open and close? Am I overtrading or undertrading?
Win rate for the week. One week is not statistically significant, but track the trend.
Total P&L. Am I on pace for my annual targets?
Process score average. If my average process score is below 3.5 out of 4, I am breaking rules too often.
Biggest win and biggest loss. What drove them? Was the big loss a rule violation?
Rules violated. Write them down explicitly. "I held past my 50% target on the MSFT trade because I felt greedy."
Upcoming events. Earnings, Fed meetings, CPI — what is happening next week that affects my positions?

Monthly Review (1 Hour)

At month-end, go deeper:

Monthly P&L and cumulative P&L. Plot these on a chart. Is the equity curve smooth or jagged?
Win rate and average win/loss. Calculate your expectancy: (Win Rate x Avg Win) - (Loss Rate x Avg Loss). This must be positive.
Strategy breakdown. Which strategies made money? Which lost? If iron condors are -$500 but credit spreads are +$2,000, you have a data-driven reason to trade more spreads and fewer condors.
Underlying breakdown. Which tickers were profitable? Which were not? Maybe you trade TSLA well but always lose on AMZN. The journal tells you.
Time analysis. Were your losses concentrated in a specific week? Around a specific event? This reveals patterns.
Plan adjustments. Based on this data, what will you change next month? Be specific. "I will reduce iron condor allocation from 40% to 20% and increase directional spreads."

Quarterly Review (2 Hours)

Every quarter, zoom out further:

Is my strategy working? Compare actual results to backtested expectations. If the backtest predicted a 1.5 Sharpe ratio and you are at 0.5, investigate the gap.
Am I improving? Compare this quarter's process scores to last quarter. Compare win rates, average wins, and drawdowns.
Market regime assessment. Was this quarter bullish, bearish, or choppy? How did each strategy perform in this environment?
Position sizing review. Were any losses larger than my 2% per-trade limit? If so, why?
Personal assessment. Am I enjoying trading? Am I stressed? Burnout destroys performance before it destroys accounts.

Journal Tools

Spreadsheet (free): Google Sheets or Excel. Create columns for all the fields listed above. Add formulas for win rate, expectancy, and running P&L. This is where most traders should start.

TraderVue ($30/month): Automatically imports trades from your broker. Tags, notes, and analytics built in. Best for high-volume traders.

Edgewonk ($170 one-time): Designed specifically for trading journals. Rich analytics, psychology tracking, and pattern detection.

Notion or Obsidian (free): For traders who prefer narrative journaling alongside data tracking. Flexible templates and good for attaching screenshots.

The Journaling Habit

The biggest obstacle is consistency. After a winning day, you feel great and skip the journal. After a losing day, you feel bad and skip the journal. Both reactions are wrong.

Make it easy:

Keep the journal template open on a second monitor during trading hours
Fill in entry details immediately when you enter a trade
Fill in exit details immediately when you close
Do the post-trade analysis within 10 minutes of closing
Total time per trade: 3 to 5 minutes

Make it non-negotiable: Your trading day is not over until the journal is updated. No exceptions. This is a professional standard.

What the Journal Reveals Over Time

After 6 months and 100+ trades, your journal will show you:

Your actual edge (or lack thereof) with statistical confidence
Your most profitable strategy and your worst one
The days and market conditions where you perform best
Your most common rule violations
Your emotional triggers and how they affect decisions

This is data no one else has. It is your personalized roadmap to improvement. Traders who journal improve faster, trade more consistently, and survive longer than those who do not.
