Trading Journal: Your External Memory
Cultural Note: The original Chinese title is 交易日志：你的外部记忆 (Jiāoyì rìzhì: nǐ de wàibù jìyì). Your brain lies to you — the journal is the objective record that doesn’t.
Your brain lies to you. Not deliberately — it’s just unreliable by nature.
You remember last month’s big win vividly. But you remember last month’s big loss differently — you think “I was almost right” or “the market was abnormal.”
The brain beautifies profits and淡化 losses. This is human instinct.
大脑会美化盈利、淡化亏损。这是人类的本能。
So you need something that won’t lie: a trading journal.
What to Record
Every trade: date, pair, direction, leverage, logic/signal, entry price, stop price (set before opening), exit plan, position size, risk-reward ratio, result, exit reason, emotions (opening and closing), execution score (1-5), and “if I could redo, what would I change?”
The last item is most important. “If I could redo” isn’t for regret — it’s for extracting rules.
从”如果重来”提炼出了一条新规则。这就是日志的价值。 “From ‘if I could redo’ extract a new rule. That’s the journal’s value.”
Three-Month Retrospective
After three months of journaling, ask:
- Win rate? >50% = signals OK. <40% = entry logic needs improvement.
- Profit-loss ratio? Average win ÷ average loss. <1.5 = exiting too early or stops too wide.
- Maximum consecutive losses? Determines how much capital buffer you need.
- 80% of losses come from how many repeated errors? Most traders find 2-3 recurring mistakes cause most losses.
- Which emotional state produces worst results? Boredom → random entries. Anxiety → overtrading. Excitement → oversized positions. Calm → best results.
如果你发现冷静时的交易结果远好于其他情绪状态，那就得出了一条规则：只在冷静时交易。 “If you find calm-state results far exceed other emotional states, you’ve derived a rule: only trade when calm.”
The Hidden Function: Discovering Your “Time Trap”
Many losses don’t come from specific trades but from specific time periods. After three months of logging, you might discover: certain time windows have significantly lower win rates.
日志不解决你的问题。日志告诉你问题在哪。 “The journal doesn’t solve your problems. The journal tells you where the problems are.”
Texture Check:
- Find your last 10 trades. Calculate win rate and average P/L ratio. If you can’t, you lack a journal.
- Label last 5 trades with emotion tags. Which emotion produced most losses?
- Start journaling today. Three lines: what, why, result. 30 days later you’ll thank yourself.
