Why & How to Keep a Good Trading Journal
Why I Maintain a Trading Journal
I keep a trading journal because it's the only reliable way to track my progress and identify what works. Whether I'm testing a new strategy, refining an existing one, or improving execution, documenting trades is essential. Without proper records, I tend to overestimate my memory and repeat past mistakes.
How My Trading Journal Benefits Me
Developing and Evaluating Strategies
When experimenting with a new system, I log my trades to assess profitability.
I track critical metrics like win rate and overall returns.
Enhancing My Strategy
Even when a system is profitable, I always look for ways to optimize it.
Reviewing past trades helps me identify unnecessary risks or areas needing refinement.
Strengthening Execution and Discipline
Recording trades helps me stay accountable to my trading plan.
It forces me to recognize when emotions influence my decisions.
Identifying Weaknesses and Fixing Bad Habits
Journaling reveals recurring mistakes in my trading patterns.
For instance, if I consistently enter trades too early or exit prematurely, my journal highlights these tendencies.
Reinforcing Positive Habits
I document what I do well to encourage repetition of successful behaviors.
Recognizing strengths is just as crucial as correcting errors.
What I Include in My Journal
My trading journal goes beyond simple trade entries and exits - it provides a comprehensive overview of factors affecting my performance.
Date & Time: Helps track trends over time.
Ticker & Setup Category: Categorizes trades to identify effective setups.
Entry & Stop Levels: Compares planned execution versus actual execution.
Market Conditions: Notes major events like FOMC meetings or breaking news.
Risk Size & Justification: Explains why I allocated a specific risk percentage.
Execution Plan: Outlines my profit targets and stop-loss strategy.
Expected Win Rate: Ensures honest assessment of probability.
Max Favorable/Adverse Excursion (MF/MAE)
MF: Measures how far the trade moved in my favor.
MAE: Tracks the maximum drawdown before success or failure.
Final Outcome: Evaluates whether I executed well or let emotions interfere.
How I Analyze My Journal Data
Filtering by Setup Type: Uses Excel to analyze performance across different strategies.
Day of the Week Performance: Identifies patterns in profitability based on trading days.
Comparing Planned vs. Actual Entries: Reveals whether I consistently enter at poor prices.
Assessing Risk vs. Win Rate: Helps adjust risk allocation based on strategy success rates.
Spotting Emotional Errors
Do I exit profitable trades too soon?
Do I hold onto losing trades for too long?
Final Thoughts on Journaling
A trading journal isn't just about logging trades - it's a tool for self-awareness. The goal is to build consistency, minimize emotional mistakes, and develop discipline. Even when I think I understand my weaknesses, writing them down forces me to confront and correct them.
