A journal that logs only profit and loss tells you what happened, never why. The fields that change behaviour are the ones measured before the trade: distance to the Max Loss Limit at the open, size as a fraction of that remaining room, and the session window. Four numbers logged daily beat a page of narrative written after a loss.
Why does a profit-and-loss journal not help?
A profit-and-loss journal does not help because it records outcomes you already know. Monday minus $180, Tuesday plus $420, Wednesday minus $60. Read it back a month later and there is nothing to act on.
A result is an outcome, and outcomes over forty trades are mostly noise. What is not noise is the decision you made before the trade: that is the part you control and the part that repeats. On an evaluation or funded account there is a second reason to log inputs. The rules that end an account measure specific quantities, and a journal that omits them cannot show you approaching them.
What should you write down before the first order?
Write down the distance to the Max Loss Limit before the first order, every session. Not the account balance: the room left below the limit.
The two diverge quickly, because the limit trails your best closing balance and locks only once you are $100 above the starting balance. A 50K account that peaked at $52,000 and gave back $1,600 shows a balance of $50,400 and a limit at $51,000. The balance looks healthy. The room is $400, not the $2,000 a fresh account carries.
Logged daily, that one figure tells a story no result column can. A sequence like 2,000 → 1,850 → 1,400 → 1,410 → 900 is an account being consumed, whatever the weekly total says. The mechanism is in the trailing drawdown article; the journal is what makes it visible on your own account.
How much should you risk per trade?
Risk a fixed fraction of the remaining room per trade, and log the fraction rather than a dollar figure. A percentage of the room shrinks on its own after a losing day; a dollar figure does not.
A working figure is 10% of remaining room. On a fresh 50K that is $200 per trade. After a $600 losing day the room is $1,400 and the budget falls to $140 by itself. Kept in dollars, it would stay at $200 until the account fails.
| Remaining room | 10% per trade | MES contracts, 10-point stop | ES contracts, 10-point stop |
|---|---|---|---|
| $2,000 | $200 | 4 | 0 |
| $1,600 | $160 | 3 | 0 |
| $1,200 | $120 | 2 | 0 |
| $800 | $80 | 1 | 0 |
A 10-point stop costs $500 on the E-mini S&P 500 at $50 a point, and $50 on the Micro E-mini. The first never fits a 50K budget. That is the whole argument of the micros versus minis sizing tables. If the fraction keeps forcing you below one contract, the account is too small for your stop distance: compare the room each size carries on the pricing page.
How do you tell whether your stops are working?
Compare the loss you permitted per trade with the worst single loss you actually took that day, and log both. The gap between the two is the measure of whether your stops are working.
When the two match, the stops are holding. When the worst loss is routinely double the permitted one, you are not running the plan you wrote, and no commentary about psychology will fix a number simply larger than the one you chose. This pair is the most diagnostic in the journal and takes ten seconds a day to fill.
Why log the time of your first and last order?
Log the clock, first order and last order, because the timestamps expose both where your profit comes from and where an avoidable cost begins. Two separate reasons.
First, results cluster. Three weeks of timestamps usually show profit arriving in one or two hours and losses in the quiet stretch after them, which is actionable in a way a win rate is not.
Second, flat time: 4:15 pm ET on Rithmic, 4:45 pm ET on Tradovate. Open positions are closed at market at whatever the close gives, and the result lands on the closing balance the trailing limit measures. A last order after 3:45 pm ET, repeatedly, points at an avoidable cost.
Where does the daily result belong in a journal?
The daily result belongs in the journal after the inputs, not before them, because its job is different: it feeds the rules that gate a pass and a payout rather than the decision you are about to make.
The consistency rule compares your largest profitable day with the net profit of the cycle. On a Clear evaluation the threshold is 50%, so a 50K account needs its best day to sit under half of $3,000, that is $1,500. On a funded Cycle the threshold is 40%. A column of daily results makes that ratio computable at any point, weeks before the check is run, which is when it can still be influenced.
The same column shows whether you are clearing Clear’s minimum daily profit of $150 on the days that count toward a payout.
Should you write a commentary after each session?
Write one line, not a page, and write it the following morning rather than straight after the session. The delay is the point: a note written at 4:20 pm after a loss is an argument with yourself, and a note written at 9:00 am the next day is an observation.
Keep it factual. “Moved the stop twice on the 10:40 trade.” “Added a fourth contract without deciding to.” Those sentences accumulate into a list of specific, repeating errors, which is what a review needs.
How do you review a journal in fifteen minutes?
Review the journal once a week, on a fixed day, with the week closed. Five checks, in this order.
- Room trend. Is the distance to the Max Loss Limit lower than last Monday? If yes, nothing else in the review matters until sizing is cut.
- Discipline gap. On how many days did the worst actual loss exceed the permitted one? Any number above one is a sizing problem, not a market problem.
- Window. Where did the money come from, by hour? Trade less outside that window.
- Consistency ratio. Largest profitable day ÷ net profit so far. Compare against your family’s threshold.
- One change. Pick one adjustment for next week and write it down. Two make the next review unreadable.
This is also the review that tells you when an account is no longer worth defending, and when restarting at full room costs less than grinding on a damaged one. The arithmetic of that decision is in the article on the price of a reset.
What can a journal not do?
A journal cannot supply an edge. It is a measuring instrument: measuring a losing strategy tells you precisely how it loses, which is useful and not the same as a fix.
It also cannot be filled in retrospectively. The room and the per-trade budget have to be written before the first order, because their whole function is to constrain the decision that follows. Entered at the end of the day, they become a record rather than a brake.
