Liquidity and smart money concepts, explained
Smart money concepts (SMC) are a vocabulary for where resting orders sit and what happens when price reaches them. Stops tend to gather just beyond obvious prices — equal highs, equal lows, a pattern's own line — and a quick move through those prices that then closes back inside is called a liquidity sweep. Fair value gaps and order blocks are boxes drawn from specific bars. These words are useful when they are defined before you look at the chart: a sweep is a touch with a name, and the close still decides whether a level broke. What the label "smart money" claims — that the moves reveal the intentions of large institutions — has not been measured, and a framework that can explain every outcome after the fact cannot be wrong, which is a weakness, not a strength. The school teaches the definitions and the honest limits together.
What is a liquidity sweep?
A move through a price where stops are likely resting — such as a run of equal highs — that fails to close beyond it and returns inside. It records that orders beyond the price were filled; it does not, on its own, say where price goes next.
What is a fair value gap?
A three-bar pattern where the first bar's high and the third bar's low (or the reverse) do not overlap, leaving a price range the middle bar crossed without trading back through. It is a box drawn from bars, only as useful as the definition written down before it is drawn.
Where the stops sit
Resting orders nobody can see — and why obvious prices collect them The module
- Resting order
- An order that waits at a set price rather than trading immediately — a limit order, or a stop order before it triggers. The resting orders near price are what liquidity means.
- Unseen stops
- Stop orders are generally held by the broker or exchange and shown to nobody. Every claim about where stops sit is inference from how stops are taught, not observation.
- Stop cluster
- Many stop orders gathered in one narrow strip, because traders following the same rule — beyond the level, not on it — place them beyond the same obvious price.
- Buy-side liquidity
- Orders that would buy if price rose to them: the stops of short positions and breakout buy stops, plausibly resting above highs.
- Sell-side liquidity
- Orders that would sell if price fell to them: the stops of long positions and breakdown sell stops, plausibly resting below lows.
- Liquidity pool
- A strip where many resting orders are thought to gather — usually just beyond an obvious high or low. A label for an inference, not a measured quantity.
- Obvious price
- A price everyone can see without drawing anything: a swing high or low, a round number, the prior day's or the session's extreme. Obvious prices collect stops because stops follow them.
- Equal highs
- Two or more swing highs at practically the same price, within a tolerance fixed in advance, with no higher high between them. A record of repeated turns, and the most plausible strip of buy-side liquidity.
- Equal lows
- Two or more swing lows at practically the same price, within a tolerance fixed in advance. The mirror of equal highs, with sell-side liquidity plausibly below.
- Tolerance for "equal"
- How close two highs or lows must be to count as equal, set before looking and ideally in ATR. Without it, "equal" stretches to fit whatever the reader hopes to find.
Sweeps and inducement
A sweep is a touch with a name — and the close still decides it The module
- Liquidity sweep
- A bar that trades beyond an obvious high or low, through where stops plausibly rest, and closes back inside it on a named timeframe. The levels module's stop run, under another name.
- Sweep versus break
- Both trade through the level and trigger the same stops. The sweep closes back inside; the break closes beyond. One close decides it, and nothing before the close can.
- Swept pattern line
- A bar that trades through a pattern's confirming line — a neckline, a range edge — and closes back inside. The pattern has not completed; the line, where stops plausibly gathered, was swept. Not the same as busted, which needs a completion first.
- Grab, raid, run
- Liquidity grab, raid and stop run are largely other names for a sweep. Different words do not make different events; check each against the same close rule.
- Unfinished sweep
- A bar wicking through a level before it has closed. It is not yet a sweep or a break, and naming it early is naming a close that does not exist.
- Outcome in the definition
- Folding what happened afterwards into an event's name — "a sweep is when price takes the lows and reverses". It makes the term impossible to be wrong, and useless for the same reason.
- Mechanics, not motive
- A chart can show that stops were plausibly triggered. It cannot show who pushed price there or whether anyone meant to. "Hunt" and "trap" are stories about intent.
- Inducement
- A minor swing that is said to invite early orders, which price then trades through before turning — at a larger level in some versions, short of the obvious swing beyond it in others. As usually used, it is named only after that happens.
- Minor swing
- A swing high or low too small to be the leg's main swing point on the stated timeframe, but visible on a lower one. Legs usually contain several.
- After-the-fact label
- A name that the following bars decide. It can describe the past neatly and cannot be applied to the bar that is forming now.
- Pre-written rule
- A definition written before the move — which swing, which timeframe, which band — so that the label can be counted afterwards instead of chosen.
Fair value gaps and order blocks
Two boxes drawn from bars — only as honest as the definition written before them The module
- Fair value gap
- In a rising move, the band between the first bar's high and the third bar's low of three consecutive bars, when the first is below the third. Prices only the middle bar traded. FVG for short.
- Three-bar rule
- The test for a fair value gap: compare the first bar's extreme with the third bar's opposite extreme. If they do not overlap, the band between them is the gap.
- Imbalance
- Another name for the band a fair value gap marks: prices crossed quickly in one bar with little two-way trade. A description of that bar, not a debt the market owes.
- Displacement
- A bar, or short run of bars, much larger than those around it — commonly at least 1.5 or 2 times the ATR. The size threshold both boxes need before they are checkable.
- Fill
- Price trading back through the whole of a fair value gap; a wick into it is only a touch. Any return is also called mitigation. A later, separate event: a fill does not confirm the gap, and no fill does not refute it.
- Order block
- In a rising move, the last falling bar — the last down candle — before a large rise; the mirror in a falling move. The same box older books call a demand or supply zone. A real place on the chart; the large orders the name implies are a guess.
- Body or wick
- Whether an order block is drawn over its bar's full range or its body only. The choice can halve the box, and it must be made before the chart is read, not after.
- When a box stops counting
- The rule for retiring a gap or block — after the first return, after a close through it, or never. Left unstated, one box can be declared respected any number of times.
- Redrawn box
- A gap or block whose edges were chosen after price reached it. It can be made to hold or fail at will, so it records nothing.
- Drawn from bars
- A term defined only by the prices of finished bars, so anyone can check it. Gaps and blocks can be; stops and intent cannot.
- Smart Money Concepts
- SMC: the vocabulary of liquidity pools, sweeps, gaps, blocks and structure breaks, sold together under a name that claims to show what large participants are doing.
- BOS, in SMC
- In most SMC material, a close beyond the prior swing in the trend's direction — a new higher high in an uptrend. Not the same event the structure module calls a break of structure.
- Change of character
- CHoCH: SMC's name for the first close against the trend through its last swing — in an uptrend, a close below the last higher low. The structure module's break of structure.
- Internal and swing structure
- SMC's names for structure on a lower and a higher timeframe. Nested structure, with the same rule: name the timeframe first and do not switch to keep a view alive.
- Dealing range
- The swing low and swing high chosen to measure premium and discount from. The choice decides every label, so it has to be written down before the chart is read.
- Equilibrium
- The midpoint of a dealing range. The same line as a 50% retracement: two chosen prices divided by two, with no information about value.
- Premium and discount
- The halves of a dealing range above and below its midpoint. Shop words for arithmetic: neither half is expensive or cheap in any sense the bars can show.
- The smart money label
- A name that assigns an actor and a motive to shapes on a chart. No bar records who traded in it or why, so the label adds a story rather than information.
- Unfalsifiable framework
- A way of reading charts in which every outcome can be explained as confirming it. It feels powerful and cannot be tested, for the same reason.
- Random baseline
- What the same measurement gives on comparable prices chosen without the idea — random bands, boxes or wicks of the same size. A count means nothing until it beats this.
- Unmeasured claim
- An idea that has been illustrated but not counted: no fixed rule, no full set of cases, no baseline. Not proven wrong — not shown to be right.
