Nothing visited that was not kept.

The shape with no shadows

A marubozu — the word means shaved or bald — is a session whose open and close sit at or effectively at the extremes of its range. The body is the whole candle; there is no meaningful wick at either end.

04.01.02 gave the two registers this collapses: a body is what the session kept, and a wick is what it visited and handed back. A marubozu is the case where the second register is empty. Nothing was reached that was not still being paid at the close.

"Effectively" is doing the usual work. Granthara's rules engine allows each shadow up to 5% of the range before it stops using the name — another chosen line, like every threshold in this Part.

The slider has been the whole Part

Look at what that one control has now produced. In the middle of its travel it gives a board with no special name at all. Pushed towards one end it becomes a long candle — 04.02.01's momentum shape. Pushed all the way, with the open already at the other extreme, it becomes a marubozu.

Those are not three patterns. They are three readings of the single measurement 04.01.04 introduced: where the last bid finished inside the range. A marubozu is that measurement at 100% with the open at 0%.

This is the last time the slider appears, and it is worth saying what it has cost to learn. One number, and most of the recognition half of Part 04 is a vocabulary for regions of it. The catalogue was never as large as its list of names.

A marubozu is the close-location metric at its limit: nothing visited was given back.

Acceleration, and the word to be careful with

A marubozu in the middle of a run is often described as the move accelerating, and as a description of consecutive boards that is checkable: the bodies grew, the shadows shrank, each session kept more of what it reached.

Two cautions, both of them old friends by now. Acceleration is relative — 04.01.03's rule — so it means bigger than the sessions beside it and nothing more absolute than that. And a marubozu is exactly the shape 04.02.05 warned about: the same board is read as a move gathering pace or as a move exhausting itself, and the difference is where it sits, which is not on it.

So the honest reading of a shaved board is the plain one. The session opened at one extreme and closed at the other. That is unusual, it is precise, and it is all of it.

That completes the recognition half of Part 04: one period, four numbers, one measurement with names for its regions, and a handful of relationships that all turned out to be containment. What remains is the harder half — what any of it is worth.
