The end-of-month summary — self-critique by the numbers

Core idea

At the end of every month, sit down and count (not "get a feel for it"): how many trades this past month were entered with a pattern, following discipline, following the theory correctly — and how many were entered on a whim. Then answer a single question: "If I removed all those whim-based trades, what would my profit be this month?" The gap between the two scenarios is exactly the tuition you're paying to your own emotions, measured in money, every month.

Why it has to be a number, not a feeling

The way everyone does a review — "this month had some wins some losses, overall it's fine" — changes nothing for the following month, because it doesn't point at what needs fixing. A summary like that is just retelling your mood.

The question "if I removed every whim-based trade, what would the profit be?" is powerful because it turns a moral piece of advice ("you must have discipline") into a number you can calculate yourself in 20 minutes. And in most cases, that number is more shocking than any lecture: the system was already profitable, the negative part is something you added yourself.

This is also why this exercise has to happen after you already have a trade journal — without records, you can't count at month's end, only guess (Notes & trading journal — the process that turns analysis into discipline).

Three layers that must be scored separately, never merged

Layer 3 is the layer that produces the number. But skip layers 1 and 2, and next month you'll repeat the exact same mistake somewhere else: someone who trades on a whim is usually someone who didn't review that month, not someone who lacks willpower.

A 20–30 minute process, done on the last day of the month

1. Open the journal, list every single trade of the month — including breakeven trades, including trades entered and exited within 5 minutes.
2. Give each trade exactly one label: CORRECT (has a pattern + followed discipline + followed the intended timeframe) or WHIM-BASED (missing any of the above conditions). There's no "nearly correct" label — a gray label is just a place to let yourself off the hook.
3. Add up two totals: P&L of the CORRECT group and P&L of the WHIM-BASED group.
4. Write one sentence: "This month my system gave me ___%. My emotions took away ___%."
5. From the WHIM-BASED group, find the common denominator: when in the day do they happen? After a winning trade or after a losing one? During a sideways market or a trend? That common denominator is the single thing to fix next month — pick one, not three.

How often to do it

• Mandatory: once a month. The teacher suggests doing it sooner if possible: once a week or once every two weeks, because the sooner a mistake is caught, the fewer trades get infected by it.
• Do it on the last day of the month, or the nearest weekend day off — you need a session with no pressure to enter a trade, otherwise you'll be scoring yourself while glancing at the chart at the same time.

The procrastination mechanism — know it in advance to block it

The teacher describes almost word for word the loop everyone falls into: lazy tonight → "I can do it tomorrow" → busy tomorrow → "the day after" → "next week" → slides into next month, and no month is ever actually sat down and reviewed. The only way to block this is to set a fixed schedule (the last day of the month, with a reminder), and treat it like a mandatory meeting — because that's exactly what it is: the performance-review meeting of this profession, the thing a boss would otherwise organize for you at a job.

Putting it into practice

1. Set up a two-column CORRECT | WHIM-BASED table in your notebook, filling it in right when you close each trade instead of leaving it all to month's end.
2. At month's end, add up both columns and write the sentence "the system gave ___%, emotion took ___%" at the top of the new month's page, so it sits right where your eyes land when you're about to enter a trade.
3. Pick one mistake to fix for the coming month, and write it as a concrete blocking rule (e.g. "no trade for 60 minutes after a stopped-out trade"), not a slogan ("must be more disciplined next month").
4. Cross-check it against the learning layer: if you reviewed fewer than 2 times that month, write that down directly as the root cause — don't blame it all on psychology.

What the teacher stresses / common traps

• The teacher states plainly the consequence of not doing this: your trading ability will stall in place for your entire time in the market, no matter how much you study. Conversely, someone who does this "progresses 5x, 10x" faster than someone who doesn't.
• The teacher points directly, in class, to who currently has profit are exactly the people who've done this — this correlation repeats across every cohort.
• Trap 1: only counting losing trades. A winning trade that happened on a whim still has to go into the WHIM-BASED column — because it's exactly the thing reinforcing the bad habit, and it will be what kills you on the tenth time.
• Trap 2: doing it half-heartedly just for the sake of it. Write "this month was fine" and close the book, and you've wasted the whole effort. "Playing half-heartedly produces no results."
• Trap 3: merging the learning layer with the trade layer. Merge them and the conclusion always comes out as "it's psychology," and psychology can't be fixed directly — whereas the learning layer can be fixed with a schedule.
