Structure & Liquidity

How Phantom defines market structure, and what actually qualifies as liquidity. The objective tests that separate a real break from a liquidity grab — and a real target from a lookalike.

Learning objective

Before you can read order flow, targets, or entries, you must define structure and liquidity the way Phantom does. The single skill this module builds: telling information apart from confirmation.

Lesson 2.1

Body Closes vs Sweeps

The foundation rule of the entire framework: structure is defined by candle body closures, never by wicks.

SWEEP — wick only swing high · liquidity Wick pokes through; body closes back inside BREAK — body close swing high · liquidity Body closes beyond the level

A wick through a level is information (a sweep) — structure is intact. A body close beyond it is confirmation (a break).

A wick that trades through a high or low is a SWEEP — liquidity beyond the level was accessed, but nothing structural has changed. Only a candle body closing beyond the level is a BREAK — acceptance, which changes the structural narrative.

Sweep — information

The wick pokes through; the body closes back inside. Liquidity taken, structure intact. Not a reason to do anything yet.

Break — confirmation

The body closes beyond the level. The narrative changes. Now you reassess structure, order flow, and targets.

By the numbers — the close is the tell
Across 7 years of daily data, when price closes beyond the prior candle it continues that way the next session ~59–64% of the time (vs a ~37% base). When it only wicks beyond and closes back inside — a sweep — continuation drops to ~25–27%, below the base rate. The same split holds on the weekly candle (~78–83% vs ~49–56%) — it's fractal. A rejected wick leans toward reversal; an accepted body leans toward continuation. (edgeful · GBPUSD/EURUSD daily & weekly, 7-yr.)

Defining bearish structure

The full definition used throughout: a lower low printed with a body closure, then a lower high, then another body closure below the low. A pop above a swing high that never prints a body above it leaves bearish structure fully intact — it's a sweep, not a break.

In other words, a wick through the level doesn't negate the bearish structure — it's a sweep, not a break. Had a body closed beyond it, the story could be different.

Defining bullish structure

The exact inverse: a higher high printed with a body closure, then a higher low, then another body closure above the high. A dip below a swing low that never prints a body below it leaves bullish structure fully intact — again, a sweep, not a break.

BEARISH STRUCTURE LL LH LL BULLISH STRUCTURE HH HL HH

Bearish structure steps down — a lower low (LL) on a body close, a lower high (LH), then another body close below the low. Bullish structure is the exact mirror — higher high, higher low, higher high. Structure only changes on body closes; wicks don't count.

The asymmetry to remember
A wick is enough to fail a zone, but never enough to break structure. Zone failure and structural break are not the same event.
Phantom Rule

Wicks take liquidity. Bodies change structure.

Common mistakes
  • Treating every wick through a level as a structural break.
  • Changing directional bias on a sweep.
  • Entering immediately after liquidity is taken — both a sweep and a break are information, not entry signals.
Lesson 2.2

Structural Liquidity

Liquidity is not every high and low on the chart. It must be objectively identifiable — and the test is structural consequence, proven with a body.

Structural liquidity exists at a real pivot: a high that has broken a low with the body, or a low that has broken a high with the body. If a swing point never broke anything with a body, it is not structural liquidity — no matter how prominent it looks.

STRUCTURAL HIGH prior swing low structural high STRUCTURAL LOW prior swing high structural low

A real pivot, both ways: a high becomes structural once price breaks a prior low with a body (left); a low becomes structural once price breaks a prior high with a body (right). Only these are sweepable liquidity — a swing that broke nothing is just a swing.

The no-pivot rule

If every candle prints higher than the last (or lower than the last), there is no pivot — and therefore nothing to sweep.

"For me there's no pivot because all the candles are printing higher than the last. So this isn't a sweep of a structural piece... I'm trying to be objective with the liquidity aspect."

Substructure counts

The pivot doesn't need to come from the main leg or from older price action to the left. Internal, sub-structural body-break pivots are fully valid — even inside a straight-line move.

"You can use substructures... you still get the low which breaks the high with the body... you sweep that and then you get a nice flip — that's perfectly good for me, I'd happily take that any day."

The inside bar — the "in-between" case

Between a clean body-close pivot (real, sweepable liquidity) and the no-pivot case (every candle printing further, nothing to sweep) sits one more shape: the inside bar — a candle that takes out neither the prior high nor the prior low. It isn't a clean structural pivot, but it isn't "nothing" either.

Mechanically, an inside bar is accumulation with a pool of liquidity on both sides: sweep the top and the bottom becomes the target (and vice versa) — the same idea whether it shows up as a single candle on the 1-minute or as a 4-hour range.

INSIDE BAR prior high · liquidity prior low · liquidity previous candle inside bar SWEEP ONE SIDE → TARGET THE OTHER top liquidity target sweep

An inside bar takes out neither the prior high nor the prior low — its whole range sits inside the previous candle, leaving a pool of liquidity on both sides. Sweep one side and the other becomes the target.

"It's not a clear structural piece, but it's also not not a structural piece... what an inside bar actually is, is accumulation — you've got liquidity on both sides. You sweep the top side, you target the bottom side."
Use it — but let your own data decide
The inside bar is the sanctioned exception to the strict pivot rule, not a loosening of it. Take it only in a high-probability context — order flow intact, a target still open, not guessing direction. And treat it as discretionary: tag inside-bar sweeps in your journal and keep them only if your own hit rate supports them. Outside that, hold to the body-close pivot.

Not to be confused with the candle-profiling inside bar — same shape, different lens. There it tells you the day is neutral (direction is open); here it's a two-sided pool of liquidity you can sweep.

Strong levels only

The level being swept must be strong — one that broke something with a body. Sweeping a weak high is not a liquidity sweep; it is simply the target being taken out.

"This isn't going to constitute the liquidity sweep, because it's not a strong high... for a structural liquidity sweep I want the high that we're sweeping to be strong."

One nuance carried into the entry lessons: liquidity is read at the timeframe of the zone you're trading — a 15-minute zone wants a 15-minute sweep — and when the leg holds none, sweeping the zone itself counts.

Phantom Rule

If it didn't break something with the body, it isn't liquidity.

Common mistakes
  • Treating every swing point as liquidity.
  • Trading "sweeps" of pivots that never created a structural consequence.
  • Selling directly off the sweep of a weak high — that's the target completing, not a setup.
  • Waiting for a big obvious left-side swing when a valid substructure pivot is right there.
  • Treating an inside bar as a clean pivot — or leaning on inside-bar sweeps before your own data backs them.
Lesson 2.3

Strong vs Weak Highs & Lows

Not all highs and lows are equal. Some are expected to hold; some are expected to fail. The distinction creates objective targets — but only in a strict order most traders reverse.

The sequence (this ordering is the whole lesson)

  1. A level fails to break the opposing structural point — "this low failed to take out the high." At this stage it is only a potential weak point.
  2. Opposing order flow takes control toward it.
  3. Only now is the level weak.
  4. Only now is it a target.
"For me to have a weak low or a weak high, I want order flow in favour going towards it... I don't want to just say this high is definitely weak — because we can pull back up into supply, supply takes control, and all of a sudden we break, and it's not weak."
Anatomy of a weak low opposing high demand weak low → target strong low — never target through 1 2 3

Read in order: 1 the rally makes a lower high, failing to break the opposing high — so the low is only a potential weak low; 2 a body then closes below the demand, confirming order flow has taken control toward it; 3 only now is the low weak — and the target gets taken. The strong low behind it is never targeted through.

The trap: when supply acted, not whether it did

The single most common way to get step 2 wrong is to count order flow that was already in control before the low formed. That control belongs to the earlier shift — it's the reason you're in the trade, not confirmation of the new low. Step 2 is a fresh control event, toward the low, after it prints.

Same low, two moments — timing is what confirms it ✗ Before the low — not confirmed opposing high supply — earlier shift ? low — not confirmed ✓ After the low — confirmed target opposing high demand 1 2 3 weak low → target ✓

Left — supply is already in control before the low prints. That control belongs to the earlier shift, so the low is only potential — the same order flow that put you in the trade can't also confirm the target. Right — after the low, price rallies but 1 fails to take the opposing high, then 2 a body closes back below the demand — supply taking control toward the low. 3 Only now is it a confirmed weak low / target. Same low, same chart — what changed is when supply acted.

Weak — a target

Failed to break the opposing point, then order flow took control toward it. Price is expected to take it.

Strong — a barrier

Broke something with a body. This is sweepable liquidity, and it is never targeted through. And once a weak level is taken, the level behind it becomes strong — the trade idea is complete.

Old strong levels decay into IRL

Strong levels are strong in their trend context. When the trend flips and the structures around them break, old strong levels lose that status and become internal range liquidity — fuel, not barriers.

"I don't want to still think about these as strong lows because we've now broken that structural trend... they'll just be catalysts for pullbacks, pieces of IRL to trade through."

A corollary applies to the zone you trade from: an extreme whose push failed to break anything is itself a potential "weak area" — let it build a new zone before trusting it.

Phantom Rule

A level becomes weak only after order flow takes control toward it.

Common mistakes
  • Calling every swing point a target.
  • Declaring a level weak the moment it fails to break — before order flow confirms (step 2).
  • Counting order flow that was already in control before the low formed as step 2 — that belongs to the earlier shift. Step 2 is a fresh control event toward the low, after it prints.
  • Targeting through strong highs or strong lows.
  • Treating old strong levels as barriers after the trend context has flipped.
