Volatility Directional Bias asks a question ordinary momentum never gets to: not how far price has travelled, but which side of the tape did the travelling. When the big ranges keep landing on green sessions, something structural is leaning upward whatever the closing price says.

That lean has a habit of showing itself before price gets round to confirming it. A market can look thoroughly undecided on a price chart while its movement has already picked a side, and this is where that shows.

What it actually measures

Above the midpoint, the roomier sessions are the advancing ones. That is what a healthy trend looks like underneath: the market spends its energy going up and merely drifts on the days it goes down.

Below the midpoint the arrangement inverts. The largest sessions are the declining ones, which argues for defence and for keeping capital intact rather than for hunting the next leg.

Sit between those and neither side is winning the argument. Trend systems have a miserable time of it, and the next regime tends to go to whoever breaks the deadlock first.

A structural lean can precede the price that confirms it

Price is a net figure and nets conceal things. A market that rises hard three days a week and drifts lower the other four can finish flat, and a chart of where it closed will describe that fortnight as directionless.

The movement itself was not directionless at all, and separating the two is the entire purpose here. What gets revealed is where the market’s energy has been going, which is a different fact from where it ended up and sometimes an earlier one.

What it does not tell you

A lean describes structure and settles nothing about the next session. Markets have carried a pronounced bias straight into a reversal, and the reading offers no protection against that whatsoever.

Stretched readings cut both ways. A pronounced upward lean is reassuring inside a trend and, pushed far enough, becomes the one-sided crowding that tends to precede a sharp snap back.

The view reads recent structure rather than the whole record, so opening it snaps the window in. That is the right default for the question and it does mean the reading describes a recent era, not a permanent characteristic.

How to read it

Bullish Bias. The roomier sessions are decisively the advancing ones, which is what a durable uptrend looks like underneath.

Neutral. A coin-toss tape. Trend systems suffer here, and the next regime belongs to whichever side breaks the symmetry first.

Bearish Bias. The largest sessions are the declining ones, which argues for defence and for keeping capital intact.

Common questions

How does this differ from ordinary momentum?

Momentum tracks how far price has travelled. This asks which side of the tape did the travelling, which can lean decisively while the closing price looks like it went nowhere at all.

What do the two boundary lines mark?

Above the upper one, the advancing sessions are meaningfully the roomier ones, which is the signature of a durable trend. Below the lower one the big ranges belong to down days. Between them the tape is a coin toss.

Why does it open on a shortened window?

Because a lean is a statement about recent structure rather than about the whole record. Entering the view snaps the window in, and any timeframe chosen afterwards sticks for the rest of the visit.

Is there such a thing as too much lean?

There is. A pronounced upward tilt is reassuring inside a trend, and stretched far enough it becomes the crowding that has tended to come before a sharp snap back.

Does a lean survive into the next session?

Not dependably. Markets have carried a pronounced bias straight into a reversal, so what this describes is the structure behind recent movement rather than a claim about tomorrow.
