A detailed log of every trade taken, including entry/exit prices, position size, strategy rationale, emotional state, and outcome. Trading journals are used to review performance, identify patterns, and improve decision-making over time.
Why It Matters
- 1A trading journal is the single most effective tool for improving your prop trading performance.
- 2Without one, you're relying on memory and gut feelings to assess what's working and what isn't. A good journal reveals patterns you can't see in real-time: maybe you lose money every Monday morning, or your win rate drops after 3 PM, or your losses are always bigger when you skip your pre-market routine.
- 3In prop firm evaluations, reviewing your journal between phases can be the difference between failing again and making targeted improvements.
Example
- 1Your trading journal reveals that over the past 30 days, your win rate on trades taken in the first 30 minutes of market open is 72%, but trades taken between 12 PM and 1 PM have only a 38% win rate.
- 2You also notice that trades where you noted 'frustrated' or 'impatient' in the emotional state column have a 25% win rate.
- 3These insights lead you to stop trading during lunch hours and implement a mandatory pause after 2 consecutive losses.
Common Mistakes
- ✖Only recording trade details (entry, exit, P&L) without noting emotional state and thought process
- ✖Keeping a journal but never reviewing it to extract actionable patterns
- ✖Stopping the journal habit once things are going well — consistency is key
