Visuals and Logic

A working assumption: if you only read one page of this pack while the chart is open, this is the one. The Settings page tells you how to set the pane up. The Workflows page tells you how to use it inside a process. This page tells you how to look at it once it is in front of you, which is the part that has to survive every kind of pressure your reading session is going to put on it. Skim this when you are calm so the patterns are familiar when you are not.

The page assumes you have the default configuration from Quick Start on a chart you know. If you landed here looking for a specific symptom, Troubleshooting is organized by what you are seeing and may get you to an answer faster.

What is on the pane

Beneath the price chart, the indicator opens a dedicated pane bounded by five horizontal guides:

A solid red line at 100 — the upper boundary of the normalization.
A dashed gray line at the Overbought level — default 80, adjustable.
A solid gray line at 50 — the mid-line.
A dashed gray line at the Oversold level — default 20, adjustable.
A solid green line at 0 — the lower boundary of the normalization.

Inside those guides you will see the following elements, each when the corresponding setting is on:

Three slot lines — CVD 01 (teal family), CVD 02 (aqua family), CVD 03 (blue family). Each line is its own slot's smoothed, normalized CVD.
A blended CVD line — lime when the blend is above its signal, red when below. Thicker than the slot lines by default.
A blended signal line — gray, same thickness as the blended CVD.
A translucent fill between the blended CVD and the blended signal. The tint tracks the blend state (lime tint when blend is above signal, red tint when below).
Dashed vertical lines in each slot's color, when that slot is in Session mode and a window anchor rolls over.

Nothing else is drawn on the pane by default. If you are seeing something that is not on this list, Troubleshooting is the place to start.

Slot line color rules

Each slot line flips between two tones based on whether that slot's CVD value is above or below its own signal line.

Up tone (opaque teal / aqua / blue) when slot CVD is above slot signal.
Down tone (faded teal / aqua / blue) when slot CVD is below slot signal.
Fallback rule when the signal is unavailable at a given bar (typically during warm-up after a chart load): above 50 is up, below 50 is down.

The flip happens the instant the lines cross. There is no delay, no edge detection, no minimum-gap requirement. A hair-crossing flips the color the same way a decisive crossing does. The Alerts page walks through why that matters for alert wiring, but the reading consequence here is: weight your attention by the distance between the slot's CVD and its signal, not by the fact that a flip happened.

Blended line color rules

The blended CVD follows the same rule one level up: lime when the blend is above the blended signal, red when it is below. The blended signal line is always gray. The fill between them takes the tinted version of the current blend tone.

Unlike the slots, the blend uses weighted-mean CVD and weighted-mean signal from the active slots. A weight-zero slot still plots; it just does not move the blend. A disabled slot disappears from both the stack and the blend.

Slot line meanings

Line inside the middle band

A slot's CVD sitting between the Oversold and Overbought guides (default 20 and 80) is reporting ordinary conditions relative to the window's recent range. Most of what you look at on any instrument will be inside this band. It is not a "no information" zone. The slot's color inside this band still carries the pressure-state read relative to the slot's own signal.

Line approaching Overbought (upper band)

The slot's cumulative delta is moving toward the upper end of what the window has observed so far. Three readings are worth carrying here:

Genuine one-sided pressure. The slot has genuinely absorbed more buying participation than selling participation across the window, and the normalization is reporting that honestly.
Quiet window, small cumulative. The window has not moved much either direction, and a small net delta is pinning the line against the observed high. The pane is describing the window more than the market. The telltale here is that the slot's line was flat in the middle and then jumped to the upper band on a small-looking bar. Compare against price for confirmation.
Approach into a fresh reset. The slot's window rolled over recently and the cumulative has not had time to form a meaningful range. The first several bars of a new window tend to travel through extremes because the window has only seen itself.

Line approaching Oversold (lower band)

Mirror of the above. Either genuine one-sided pressure, a quiet-window artefact, or a recent reset. The same telltales apply with the sign flipped.

Line hugging 50

The slot's cumulative delta sits near the midpoint of the window's observed range. This is not the same as "neutral participation." It is "the current cumulative is somewhere in the middle of what the window has seen." A slot that was at 20, climbed to 80, and now sits at 50 is showing a cumulative that is halfway back through a known range. A slot that has wandered around 50 for most of the session is showing a cumulative that has not pushed through its observed extremes.

Slot line transitioning between bands

Rate of transition carries information. A fast transition through the middle band is the slot committing: the estimator is seeing decisive bars and the cumulative is moving quickly against the window's range. A slow transition is the opposite. Both are legitimate reads; what matters is whether the rate of transition fits the bar character you are seeing on price.

Color flips

A color flip is the slot's CVD crossing its signal. It is a pressure-state change. It is not a direction call about price.

Small-gap flip. The lines crossed but the gap between them is tiny. The color flip looks identical to a decisive one. Treat these as ordinary noise unless they are confirmed by something else you are already watching.
Large-gap flip. The lines crossed with visible separation. This is the estimator committing harder to the new state — the signal had been running clearly above or below, and the CVD line has now clearly pushed through.
Flip on a resetting slot. A slot whose window just rolled over may flip color on thin evidence because the new window has only observed a few bars. Treat the first several bars of a new window as calibration time, not signal time.

The blended line

The blend is a weighted average of the active slots' CVD values and a weighted average of their signal values. Its color follows the same rule as a slot's: above its signal is up-toned, below is down-toned.

There are four states worth naming explicitly, because they are read differently.

Blend in the upper band, fill strong lime

All active slots lean bullish, or nearly all, and the weighted average is above both its signal and the 80 guide. The fill intensifies as the blended CVD pulls away from the blended signal. This is the pane's cleanest "aligned pressure" picture.

The thing to check before leaning on it: is the 80-plus position driven by genuine slot agreement, or by one slot pinned at 100 and two slots in the middle? A blend at 85 with three slots at 85 is not the same read as a blend at 85 with one slot at 100 and two at 77. Both can be legitimate, but the second one is a weighted-average artefact that will collapse faster when the top slot comes off the ceiling.

Blend in the lower band, fill strong red

Mirror of the above. The same check applies: is it broad participation agreement, or is it being carried by one slot pinned at 0?

Blend near 50, fill thin

This is the ambiguous middle, and it is the reading the pane gets wrong most often when the blend is read in isolation.

Slots aligned near 50. The three slots are each sitting mid-range in their own windows. The blend summary is accurate. The pane is reporting ordinary conditions.
Slots spread across the pane. One slot near 80, one near 50, one near 20. The weighted average is near 50, so the blend looks quiet. The blend is not reporting silence; it is reporting cancellation. This is an entirely different situation from "ordinary conditions" and it will resolve in a different way.

See Ambiguity walkthrough: blend near 50 below for the extended version of this case.

Blend whip-flipping color

The blended CVD and the blended signal are crossing repeatedly with small gaps. This is usually one of two things:

Small-gap crossings cascading from the underlying slots. The three slot pairs are each producing hair-crossings, and the blend inherits the hair behavior. Smoothing the CVD or signal by one or two bars, or turning Master Smoothing on briefly, will show whether the underlying character is genuinely whippy or whether the plotted lines are rougher than the underlying data.
Weight changes on a recently reset slot. A slot that just reset may be contributing disproportionately for a few bars while it calibrates. As the slot stabilizes, the blend settles.

Ambiguity walkthrough: blend near 50

This is the single ambiguity that this pack wants you to internalize before you use the blend in any kind of decision process. The blend at 50 is not one state. It is two, and they carry opposite information.

State A: blend at 50, slots aligned at 50

CVD 01 near 50, CVD 02 near 50, CVD 03 near 50.
The blend is the weighted average: also near 50.
Fill is thin; the blended CVD and blended signal are close together.
The pane color is often whipping in small-gap flips, because all three lines are sitting on their signals.

The reading: the instrument is in balanced participation relative to each slot's window. Buyers and sellers are roughly matched on every timeframe you are watching. This is ordinary. Nothing is being hidden.

State B: blend at 50, slots spread

CVD 01 near 80 (bullish pressure on the short frame).
CVD 02 near 50 (mid-range on the middle frame).
CVD 03 near 20 (bearish pressure on the slow frame).
The weighted average is near 50.
The blend looks identical on the chart to State A unless you are watching the stack.

The reading: the timeframes disagree. Short-term participation is leaning one way while the regime frame is leaning the other. The blend is averaging the disagreement, and the average happens to land in the middle. This is a situation where the blend is carrying real information — the information that there is no consensus — and a reader who treats it as "balanced" will miss what the stack is actually saying.

Both states are correct summaries. They are not the same read. The mature posture is: check the stack before you let the blend speak for the pane. When the three slots agree, the blend is a clean shortcut. When they disagree, the blend is a compressed headline, and the story underneath it matters.

How to tell A from B

Turn your eye to the three slot lines first, not the blend.
Ask: are the three lines clustered, or spread?
If clustered, the blend is a faithful summary. Read it.
If spread, ignore the blend for the decision and read the stack directly. The blend is telling you nothing about direction; it is reporting that the three contexts are arguing. That argument is often the most useful thing the pane has to tell you.

Why the trap is sticky

The blend draws thicker, draws in colors that pull the eye, and carries a fill that dominates the pane visually. The slots are thinner and quieter. Under attention pressure — a fast tape, a position open, an alert that just fired — the eye reaches for the loudest object on the pane, which is the blend. The pack makes the blend visually dominant on purpose because for most reads the blend is the right summary; the price of that dominance is that under exactly the conditions where the dominance becomes a liability, the eye stops checking the stack. Knowing the trap is sticky is part of why naming it does not make it go away. Make checking the stack a habit before the moments that make the habit hard.

The fill between the blend and its signal

The fill is always drawn when Plot Blended CVD/Signal is on, and its tint follows the current blend state. The hue intensifies as the gap between the blended CVD and the blended signal widens.

Three things to carry about the fill:

It is a state cue, not a confidence score. The fill tints the moment the blend crosses its signal, even on a hair-crossing. A small gap will still produce a visible tint because the shader runs regardless of gap magnitude.
Wide fill is meaningful; narrow fill is quiet. When the fill is noticeably wide, the blended CVD is running clearly above or below its signal, and the blend's state is committed. When the fill is narrow, you are in a crossing-prone stretch and small-gap flips are likely.
Fill intensity can trick the eye. Because the fill is always there and always tinted, even whisper-sized crossings read as loud. The pack names this as the "fill intensity illusion" because it is a real trap. When the fill is narrow and flipping, do not read it as regime change.

Session reset dashes

In Session window mode, a dashed vertical line in each slot's color drops on the bar where that slot's window anchor rolls over. This is not a price event. It is a bookkeeping event. The next slot bar begins a fresh cumulative period, and the normalization starts observing a new range.

Only Session mode draws the dash. Rolling mode has no reset event, by design. If you are in Rolling and wondering where the dashes went, that is the reason.
Only visible slots draw the dash. A slot with Hide Plot on does not draw its dashes even if its math is still running.
The dash lands on the first bar of the new window. It does not land on the last bar of the old window.
Trade-adjacent misread. Some readers will see a dash, notice the slot line moving quickly just after, and take that as a trade event. The line is moving quickly because the new window has only observed a few bars — it is calibration behavior, not market behavior.

Quiet-window pinning

The most misleading single state on the pane is a slot line that is pinned at 0 or 100 for a long stretch. Two things can produce that picture.

Sustained one-sided participation. The cumulative delta has genuinely climbed to the top (or dropped to the bottom) of the observed range, and the instrument has been under one-sided pressure. The line pins because the range keeps being extended by the same movement that is producing the pressure.
Quiet window. The window has not seen meaningful delta variation, and a small net delta has pushed the line to one extreme. The range is narrow, so the same modest cumulative that would sit mid-pane on an active window sits at an extreme on a quiet one.

The reading move is to compare the pane read against price. If the instrument is clearly in a one-sided regime on the chart, the pinning is the pane agreeing with what you already see. If the instrument has been chopping in a tight range and one slot is pinned, the pane is describing the window more than the market. Neither is dishonest; they are different pictures, and the pane cannot tell them apart for you.

Pressure is not direction

This is the distinction the whole pane lives on, and it is worth saying plainly because experienced traders still slip on it.

Pressure is the weight of participation on one side of the tape, as estimated from participation-weighted volume in the slot's window.
Direction is which way price is actually moving.

They often align. They can also diverge — markets can rally into selling pressure before rolling over, markets can sell off into buying pressure before turning up. When that happens, the pane is not malfunctioning. It is reporting pressure honestly, and price has not yet reacted.

If you come into the pane expecting it to predict price, you will read every divergence between pane and price as a failure of the tool. The pane is not built to predict price. It is built to show you where the pressure sits. What you do with that information is a separate skill, and most of the Workflows page is about how that skill shows up in practice.

A short check you can run on yourself: when the pane and price disagree, what is your first instinct — to question the pane, or to question your own read of price? Most readers question the pane first, because the pane is the new thing. The honest answer is that neither is wrong. The pane is reporting participation as the estimator sees it; price is reporting the outcome of pressure against opposing forces. The disagreement is information about the gap between those two, and the pane has done its job by surfacing it. What that gap means for your decision belongs to your process, not to the indicator.

What the pane cannot show you

It cannot show you what is on the other side of the tape. It cannot show you resting liquidity, stop clusters, or the orderbook shape. It cannot distinguish aggressive participation from passive participation. It cannot tell you whether a large imbalance is being absorbed or whether the absorption is about to fail. Those are different instruments, and pretending this pane covers their job would be dishonest. Limitations and Trust Boundaries keeps the inventory.
