The Trading Journal as a Magical Diary: Documenting Like an Occultist
Of all the tools of the old schools, one is completely unsuspicious, completely legal and completely underestimated: the diary. Not the diary of feelings, kept when one feels like it — but the protocol, kept because it is kept. This letter transfers that method to the markets.
Why the old schools wrote
Whoever practises a hidden discipline has a problem every trader knows: there is no external referee. Nobody tells you whether your exercise worked or whether you imagined the effect. In his own cause, man is the most corruptible of all judges — he remembers hits and forgets misses, he re-dates hunches after the fact, he turns luck into skill.
The solution of the old teachers was of merciless simplicity: write down beforehand what you expect. Write down afterwards what happened. Change nothing retroactively. The diary was not kept to celebrate successes, but to catch self-deception — in black and white, with a date.
Replace “exercise” with “trade” and you have the complete recipe. The market is the perfect stage for self-deception: every price move can be explained in hindsight, every defeat externalised. The protocol is the only tool that stops these tricks — not through discipline, but through evidence. It is the first degree of the banishing of emotion: what is fixed in writing can no longer be secretly renegotiated.
The form of the protocol
A protocol that flatters is worthless. So that it does not flatter, it needs a form — and the form has two halves.
Before the trade, in the stillness, before anything is at stake:
- The reasoning. Why this market, why now? An honest reasoning fits in two sentences. Whoever needs more is currently talking himself into something.
- The conditions. What must occur for the position to be opened — and what for it to be closed? Both belong on paper before the first order exists.
- The state. Three words about yourself: tired, calm, irritated, euphoric. After a year, these three words are the most valuable field of the entire protocol.
After the trade, without a day’s delay:
- The result as a ratio. Not as an amount — amounts seduce or shame, and both are bad teachers. A percentage suffices; the profit factor across many trades says the rest.
- The deviation. Where did you deviate from the plan, and under which feeling? This is where the real insight lives. A trade that lost according to plan is a good trade. A trade that won against the plan is a defeat in disguise — it teaches you to break the plan.
- The state during the position. When did you want to intervene? What did the impulse whisper? Note the exact wording. The two demons repeat themselves astonishingly verbatim.
The review: the ritual of looking back
A protocol nobody reads is a graveyard. The old schools read their diaries at fixed intervals — not by desire, but by calendar. Adopt that: behavioural patterns weekly, numbers monthly.
In the weekly review you look not for profits but for repetitions. Which state preceded the deviations? At which hour, after how many hours of screen, after which kind of previous day? You will find patterns nobody could have told you, because they are yours alone.
In the monthly review, the ratios count: profit factor, maximum drawdown, the ratio of plan trades to impulse trades. That last number is the most important of the whole system. It does not measure the market — it measures you.
And one principle stands above all, with its own letter: loss days are sacred. They are recorded like all others, in the same typeface, at the same size. A journal missing its red pages is not a chronicle but advertising — and you are its first victim.
When the machine trades
Acta Abyssi documents a system that decides for itself. Does that make the journal obsolete? On the contrary — it moves up one level. The machine records its trades itself, incorruptibly and completely. The human now records something else: his own impulses to intervene. Every moment in which the hand reaches for the keyboard, just this once, is noted the way a trade used to be.
For this is the last self-deception of automated trading: believing you have banished emotion because a machine places the orders — while hovering with a finger over the off switch. The diary catches this demon too. It has caught every single one that was ever written into it.
Write. Before, after, unchanged. It is the oldest magic there is, and the only one that can be proven.

Questions on this letter
What belongs in a trading journal?
Before the trade: reasoning, conditions, planned exit, inner state. After the trade: the result as a ratio, deviations from the plan, your state during the position. The decisive point is writing both before and after the trade — never only afterwards.
Why record your emotional state?
Because patterns of self-deception only become visible in hindsight. Whoever notes for months how he felt before bad decisions learns his personal warning signs — euphoria, revenge, exhaustion — before they trigger the next order.
What distinguishes a protocol from a success story?
A protocol is written before the result and never changed afterwards. A success story is written after the result and leaves out the losses. Only the protocol has evidential power — towards others and towards yourself.
How often should the journal be reviewed?
At fixed intervals, not by mood: weekly for behavioural patterns, monthly for metrics such as profit factor and drawdown. Reviewing by mood means you only look in during good phases.
Is a journal useful when a machine trades?
Yes — it moves up one level. Instead of individual trades, you record the system's behaviour and your own impulses to intervene. The most dangerous moment of automated trading is the human who wants to step in "just this once".
