How this was sourced. Ratigan Capital did not read the full book for this lesson, and we found no publisher-authorized excerpt. The ideas below are paraphrased from the book’s widely reproduced lists and checked against several independent secondary summaries that agree with each other. Treat the wording as our paraphrase, not a quotation.
What you will learn
- Mark Douglas’s seven principles of consistency, restated as checkable journal fields.
- How to separate process quality from outcome.
- How a fixed review batch works, and what it can and cannot tell you.
The seven principles, as checks
In Trading in the Zone, Douglas wrote seven principles in the first person. Paraphrased, they are: identify your edges objectively; predefine the risk of every trade; fully accept that risk or let the trade go; act on your edge without hesitation; take profits when the market offers them; keep monitoring your tendency to make errors; and treat these principles as non-negotiable.
Mottos do not help much on their own. Turned into yes/no fields, they become measurable:
- Objective setup? Could someone else confirm the setup from my written rule?
- Risk predefined? Entry, stop and size written before entry?
- Risk accepted? Pre-trade reaction line filled honestly (see the previous lesson)?
- Executed without hesitation? Entered at the planned trigger, not late or early?
- Exit per plan? Took profit or exited by the written rule?
- Error noted? Any deviation logged with a reason?
- All rules followed? Yes only if 1–6 are yes.
Process grade versus outcome
Each trade gets two separate scores: a process score (0–6 from the checks) and an outcome in R. Four combinations matter: good process and win, good process and loss (fine, the cost of doing business), bad process and loss (the lesson is in the process), and bad process and win (the most dangerous, because it rewards a habit you do not want).
A fixed review batch (Ratigan Capital practice)
This is our own review habit, built on Douglas’s idea of taking every signal and judging a series of trades rather than one. The batch size is arbitrary. We use 20 as an example because it’s easy to review, not because it proves anything. The mechanics:
- Decide the rule, the risk per trade, and the batch size before starting.
- Take every qualifying setup in the batch, at the same risk. No rule edits mid-batch.
- At the end, review two questions separately: did I follow the rule, and what did the results look like?
IF–THEN example (hypothetical, educational)
- IF a trade scores below 6 on process, THEN it is logged as a deviation even if it made money.
- IF I have three deviations in one batch, THEN I pause and review execution before continuing.
- IF the batch ends with high process scores but poor results, THEN I treat it as weak evidence about the rule and plan a larger, cost-inclusive test (see the planned lesson Testing a strategy honestly).
Limitations
- A batch this small proves very little about a rule. They mainly show whether you can execute it. Distinguishing a real edge from luck usually needs far larger samples, and even then regimes change.
- “Take every signal” assumes the rule is objective enough that “every signal” is clear. Vague rules make this impossible.
- Paper and live execution differ: fills, fees and emotions all change with real money.
Exercise (paper journal)
- Copy the seven checks into your journal template as columns, plus “Outcome (R).”
- Score your last 10 trades or paper decisions from memory or records. Be strict: unknown counts as no.
- Count the bad-process wins. Write what habit each one rewarded.
- Write your next batch plan: rule, risk per trade, sample size, review date. Do not start trading because of this exercise.
Check your understanding
A trade broke two of your rules but made 3R. How should it be graded?
As a process failure with a positive outcome. It should be logged as a deviation, because it reinforces a behavior you do not want.
After a clean review batch of 20 trades with good results, is the rule proven?
No. It is a small sample. It shows you can execute; it is at best weak evidence about the rule.
Takeaway
Measure what you control. Score process every trade, fix your sample in advance, and keep results and rule-following in separate columns.
