A green day that was still a bad day

A trader finishes a session up twenty dollars and grades the day an F.

Not out of theatre, and not on a bad day. He was up seven, trading the plan, then took a revenge short after a loser and spent the rest of the session getting back to green. The number at the end was positive. The day was a failure and he knew it.

He is not unusual. In one evening of reading public trading posts we found three more of him: one who closed four hundred dollars up and wrote that he was not happy with how he traded, one who made money while breaking his own rules and said plainly that it did not count, and one requesting his ninth payout who still described the month by his own mistakes rather than by the money.

These are people who chose to write it down, so they are not a survey. What they show is that the instinct exists and shows up unprompted, at twenty dollars and at nine payouts.

The instinct is correct, and most trading advice quietly argues against it.

The scoreboard problem

A day has two results, and only one of them is on your statement.

The first is the money. The second is whether you did what you said you would do before the session started. They come apart constantly, and the day they come apart is the day that teaches you something, because a profitable rule-break pays you for the exact behaviour that will take the money back later.

Most journals record one axis. The P&L knows the difference between a good day and a bad one only in money, so a month of green days looks like a month of good days. It is a month of good days only if the second column agrees, and there is no way to know without writing it down while the session is still fresh.

Why the green rule-break is the expensive one

A loss teaches quickly. It hurts, you look at it, you say it out loud, and there is a decent chance you change something.

A win from a broken rule teaches too, and it teaches the wrong lesson, quietly, with no pain attached to make you look. The trade that worked is now filed as evidence that the rule was optional. Nothing in the balance flags it. Nothing in your review flags it, because most reviews start by asking why the red days went red.

That is how the revenge trade survives its first month. It got paid once.

What the two axes look like over a month

Grade each day twice: what the money did, and whether you followed your own rules. Two marks, ten seconds, at the close.

After twenty sessions you have something a statement cannot give you. You can see whether your green days are being earned or collected, and whether your red days are the price of an edge or the same mistake wearing different tickers.

Most traders find the two rows disagree more than they expect, and the disagreements cluster. Certain days, certain hours, certain instruments, usually after a specific kind of loss.

The grading rule that holds up

A day is a good day when you would be content to repeat exactly what you did for the next hundred sessions.

That is the whole test, and it settles the awkward cases. Twenty dollars made by breaking the rule you wrote on Sunday is not something you would want to repeat a hundred times, because the hundred-session version of that day includes the one where the revenge trade does not come back. A red day where you took the loss you planned to take, at the size you planned to take it, is exactly what you want a hundred of.

The trader grading himself F on a green day is not being hard on himself. He is using the only scoreboard that generalises.

Where this leaves your journal

If you keep one, add the second column tonight. Not a paragraph, a mark. Followed the plan, or did not.

If the two columns are still disagreeing in a month, you have found the thing worth working on, and you found it without needing a losing streak to point it out.
