Granthara04.07.01Why a detection library is not a syllabus

Every board in Part 04 is a synthetic teaching example from an unnamed market. Nothing in this chapter is a signal, and no pattern here carries a claim about what follows it.

04.07.01 · Why a detection library is not a syllabus

PreviouslyA shape can keep appearing and still not be an edge. Recurrence and profitability are different claims.

None of them. They are for looking things up.

Rahul has found the pattern list in a charting app. There are more than a hundred names in it, with a checkbox beside each one. He has ticked them all, and the chart is now covered in labels. He wants to know which ones he still has to learn.

A list of names is an index. You do not read an index from the front.

What the remaining names actually are

Six chapters have taught you the relationships: where the close sits in the range, what a long shadow records, how two bodies can contain or penetrate one another, what a run of sessions does as it tires, and what location does to any of it.

Almost every name left in the catalogue is one of those relationships with an extra condition bolted on. A three-candle run where each session also opens at the previous close. A penetration that stops one third of the way in instead of halfway. A gap that is entered but not closed. The relationship is one you know; the name marks a particular degree of it.

That is why the rest of this chapter is a reference and not a course. There is nothing new to understand in it. There is a list of names, their measured conditions, and — for several of them — the earlier page where you already met the idea under a different word.

The tiers are a claim, and it is written down

`scripts/candle-rules.js` sorts every pattern into core, variant or advanced, and that sorting is an editorial judgement rather than a fact about markets. Core means a beginner should recognise it. Variant means a stricter form of something already core. Advanced means it is here so a name can be looked up, not so it can be memorised.

Granthara publishes the tier with the pattern for the same reason it publishes the thresholds: a reader is entitled to see where the book drew a line and to disagree with it. Another writer would move several of these, and 04.05.04 showed how little separates a name from a near-miss.

What the tiers are not is a ranking of usefulness. An advanced pattern is not a better one. It is usually a rarer one, which means fewer examples, which means the little that can be said about it rests on less.

A detection library answers the question “what is this called?”. It has never once answered “what should I do about it?”

Why ticking every box makes the chart worse

Rahul's screen is now unreadable, and that is not a display problem. 04.05.04 ran this book's grader over a thousand boards built from noise and 732 of them earned a name. Turn on every detector and you are labelling the noise as diligently as the signal, because the detector cannot tell them apart and neither can the label.

There is a second cost. A name arriving unasked stops you reading the board. You see bullish harami before you have noticed that the range halved, that it happened at a price the market argued about last month, or that almost nothing traded. The label answers a question you had not asked yet, and it answers it first.

The reference works the other way round. You read the board, you notice the relationship, and then you come and look up what it is called. In that order the name is a filing label. In the other order it is a conclusion you did not reach.

How to use the five pages after this one

Each one takes a small family, gives the measured conditions the grader actually applies, and says where you met the idea before. They are short on purpose and they are not sequenced — nothing in 04.07.05 depends on 04.07.04.

Read one when you have met the name and want to know what it means. Skim them once now if you like, so you know what is in the index. Do not learn them.

And where a name is a second word for something you already know — kicking for kicker, counterattack for meeting lines, stalled for deliberation — the page says so plainly. A catalogue that has collected two names for one thing has told you something about the catalogue, not about the market.

What is deliberately not hereNo pattern in this chapter is given a success rate, a target, an entry or a stop. 04.05.04 explains what a statistic would have to measure before it meant anything, and Granthara has not done that work for any of these. A reference that tells you what a shape is called is honest. One that tells you what it pays is making a claim it has not earned.
Remember

The remaining names are relationships you already know with an extra condition attached, which is why the rest of this chapter is a reference rather than a course. Granthara's grader implements 67 patterns across three tiers, and the tiers are an editorial judgement it publishes so you can disagree with it. Read the board first and look the name up afterwards; a detector turned on for everything labels noise as carefully as anything else.
