Journaling: Your Edge, Documented

The Trade Terminal has a journal tab — here is what to write in it.

Written and reviewed by the Fundezy team · how we produce this

Every professional tracks every trade. Not for nostalgia — because your trade history is the only dataset that reveals your personal edge, and intuition is a notoriously bad analyst of it.

Why journal

Memory rewrites history: you'll remember the brilliant calls and quietly forget the impulsive ones. After 100 journaled trades, patterns become undeniable and actionable:

  • "My EUR/USD setups win 55%; my GBP/USD setups win 31%." → Trade one, drop the other.
  • "Trades I entered within 5 minutes of looking at the chart lose twice as often." → Impulse is a measurable leak.
  • "Thursday-afternoon trades are half my drawdown." → Session awareness pays.

These are real, common findings — and none of them are discoverable without records.

What to record per trade

The Trade Terminal's journal tab captures your trades; the discipline is adding the qualitative fields that machines can't infer:

  1. Setup — which strategy, which criteria (one line).
  2. Reason — the specific structure/level/candle that triggered entry.
  3. Emotional state — one word: calm / eager / frustrated / FOMO. Be honest; this is the highest-value column in the file.
  4. Plan adherence — did I follow my own rules? Y/N.
  5. Post-mortem (for closed trades) — what worked, what was luck, what to repeat.

Rules for honest journals

  • Write the entry before or at entry, never retroactively — reconstructed reasons are fiction.
  • Record the losses with the same detail as the wins. Losses contain more information.
  • Review weekly: 20 minutes, count setups, compute win-rate by category, look for the leak.

On this platform

Pair the journal with the History tab (closed P/L) and the leaderboard (long-run performance). Where the history tab tells you what happened, your journal tells you why — and the "why" is the trainable part.

By the numbers

The classic evidence for self-measurement: Barber and Odean (2000) studied 66,465 household brokerage accounts and found the most active traders earned 11.4% annually while the market returned 17.9% — undiagnosed overtrading quietly cost them the difference. A journal is the diagnostic: 100 journaled trades are usually enough to see your own pattern in the data.

Practice in the simulator

Open the journal tab and log your next trade — apply what you just read with simulated money.
