The Open Position checkpoint — the moments, named

Course capstone. Four units ago "discipline" was a virtue you either had or lacked. It is now sixteen specific moments between an entry and an exit, each with a mechanism, each of which you have now seen from the inside.

The course in one architecture

When it goes against you, judgement changes before the price does — a position down 8% is a different decision from the one you opened; new reasons to hold arrive only after the fall; money already lost changes what you do next; adding to a loser feels like conviction from the inside (Unit 1).
When it goes your way, the danger has a different shape — an unrealised gain is harder to hold than a loss; the target moves once the price gets near it; size creeps after a good run without a decision; a price rising after you sold rewrites your next trade (Unit 2).
The next trade is shaped by the last one — after a loss the next trade looks nothing like the one before; boredom takes positions when nothing has happened; a run of wins and a run of losses of the same length feel different; and after a bad loss the next opportunity can be impossible to take (Unit 3).
Under real pressure the plan and the moment part company — an overnight gap, a crowd's opinions in real time, leverage that changes how you behave, and the question this course ends on: what actually changed between the plan and the moment (Unit 4).

The sentence, decoded

"I held through the drop because the thesis was intact, then sold half on the bounce to lock in gains, then bought it back higher." Run it through the instruments. The thesis was intact — or the reasons arrived after the price fell (Unit 1). Sold half on the bounce — the unrealised gain that was harder to hold than the loss had been (Unit 2). Bought it back higher — exit regret, doing what it does to the next decision (Unit 2). Three decisions, three named moments, and a plan written calmly that none of them consulted.

Where this connects

The Long Run, next in this domain, is the same subject on the scale of months and years: a drawdown lived through rather than a bad day, records that measure you rather than the market, and the point at which this stops being about markets at all. The behavioural lesson in the portfolio domain is the same mechanisms with their research names attached. And every course in the technical and fundamental domains hands you a reason to enter; this course is what happens after you do.

Checkpoint

The exam ahead draws on all four units. The bar: a moment described in a sentence, and the ability to name the mechanism and the artefact that would have caught it.

Before you sit it

Each of these is a minute at your desk. Any one that is not names the lesson to reopen first.

Say why new reasons to hold appear after a fall and not before it — Why do new reasons to hold appear only after the price falls?
Explain why an unrealised gain is harder to hold than a loss of the same size — Why is an unrealised gain harder to hold than a loss?
Describe how the trade after a loss differs from the trade before it, and what you would write down to catch it — Why does the trade after a loss look nothing like the trade before it?
Name what changes between a plan and the moment it is meant for — What actually changed between the plan and the moment?

Try it now

Write the one-sentence version of each unit from memory — four sentences, your pocket card. Do this before opening anything.
Then find the moments on a real chart. The largest US equity fund over its worst modern stretch, with the days that produced each of the sixteen moments somewhere on it:

Measure 19 February to 23 March 2020 — the drop that produced unit 1's moments — and then 23 March to 18 August 2020, the recovery that produced unit 2's. The measure tool reports the percentage and the number of bars for each, so the depth and the length are both on the page. 3. For each of the two stretches, write the sentence you would have said to yourself on the worst day of it, and name the moment it is an instance of. If you can, sit the exam.
