# SMT divergence > A disagreement between correlated instruments at time-aligned swings: one takes out its prior high or low and the other does not, a refusal the ICT method reads as a sign that price is about to turn. - Canonical: https://hadalinstruments.com/glossary/smt-divergence/ - Term set: https://hadalinstruments.com/glossary/ --- Two markets that normally move together agree at almost every swing, and SMT divergence is the name for the swing where they do not. ## The comparison, stated The object needs four things declared before it exists. A **set** of instruments whose prices normally move together, or in mirror. A **clock** that aligns them, so that a swing on one chart is compared with the candle printed at the same moment on the other. A **swing rule** for what counts as a prior high or low, the same kind of fractal rule that decides a [break of structure](/glossary/break-of-structure/). And a **test**: at an aligned swing, one instrument trades beyond its prior extreme while the other does not. That refusal is the divergence. Everything else in the vocabulary around it is interpretation. Each declaration moves the population of events. A wider set produces more disagreements, because any member can supply one. A looser clock, one that lets a swing on one chart match a candle a few bars away on the other, admits near misses that are artefacts of the misalignment rather than information. A shorter swing rule finds more extremes to disagree about, and whether an extreme must be taken by a wick or by a close is a further election. Two readers who state all four will mark the same divergences on the same data; two who state none will argue about charts. ## Bullish and bearish The orientation comes from where the swing is. **Bullish SMT** forms at lows: one instrument trades below its prior swing low while the correlated one holds above its own, printing a higher low. **Bearish SMT** is the mirror at highs: one makes a higher high while the other stops at a lower high. In both cases the method reads the instrument that refused as the one showing the real direction, the side that would not make a new low as stronger and the side that would not make a new high as weaker. A worked case, with constructed numbers and the real rule. EUR/USD and GBP/USD each print a swing low on the same hourly candle, at 1.0800 and 1.2600. Some hours later, on one aligned candle, EUR/USD trades down to 1.0790, beneath its low, while GBP/USD turns at 1.2615, above its own. EUR/USD made the lower low and GBP/USD declined to. By the rule that is a bullish SMT divergence. The rule has nothing to say about what the next candle does. ## Pairs that move in mirror Some sets are inversely related, and the test flips for them. The dollar index normally rises when EUR/USD falls, so the two confirm each other by making opposite extremes: a higher high on the index alongside a lower low on the pair. A divergence is one side failing to mirror the other, for instance the index printing a higher high while EUR/USD holds above its prior low. A set that mixes direct and inverse relationships has to state the sign of each pair, or a confirmation gets recorded as a divergence and a divergence as a confirmation. The sets most often taught are EUR/USD with GBP/USD, the S&P 500 and Nasdaq 100 index futures, and the dollar index against the euro pairs. The definition privileges none of them. The set is a parameter, and results quoted for one set say nothing about another. ## Where it sits in the taught sequence In the ICT sequence the divergence usually appears at a swept extreme. One instrument runs its prior high or low in a [liquidity sweep](/glossary/liquidity-sweep/), its partner stops short, and the refusal is read as confirmation that the sweep collected resting orders rather than starting a trend. The method then waits for a [market structure shift](/glossary/market-structure-shift/) on the instrument being traded, and an entry at a [fair value gap](/glossary/fair-value-gap/) or an [order block](/glossary/order-block/). The divergence is the cross-market clause in that sentence. The datasheet that draws it under stated parameters is the [SMT divergence indicator](/ict/smt-divergence-indicator/). ## The evidence problem Divergence borrows its persuasive force from the image of independent witnesses disagreeing, and correlated instruments are not independent witnesses. Two dollar pairs share most of their movement, so a comparison between them carries far less independent information than two unrelated observations would, and the [effective sample size](/glossary/effective-sample-size/) behind any hit-rate claim is smaller than the count of flagged events. A study that counts divergences as if each were a separate trial overstates what its sample can support. That makes the proposition under the name, that the instrument which refused leads the next move, unusually expensive to test honestly. It needs the correlation discounted, the alignment enforced, and a comparison against what the same swings do when both instruments agree. The detector’s row in the [claims ledger](/ict/#ledger) is where that comparison’s verdict renders. The [two lenses](/glossary/the-two-lenses/) keep the halves apart: the disagreement is a fact anyone can check on two charts, and what it predicts is a measurement. ## Commonly confused with Neighbouring concepts that get used interchangeably, and the distinction that actually separates them. - **RSI or oscillator divergence** — Oscillator divergence compares one instrument's price with an indicator computed from that same price, so the two series are not independent at all. SMT divergence compares two instruments' own price swings. One asks whether momentum confirms a new extreme; the other asks whether a related market does. - **Dow theory non-confirmation** — The century-old antecedent: the industrial and transportation averages were expected to confirm each other's new highs and lows, and a failure to confirm was read as a warning. SMT applies the same confirmation logic to currency pairs and index futures, with time-aligned swings in place of closing averages. - **A correlation breakdown** — A correlation breakdown is a statistical change measured over a window of returns. An SMT divergence is a single event at one pair of swings. Two instruments can stay closely correlated across a month and still diverge at one swing, so the event says nothing about the relationship as a whole. - **[Market structure shift](https://hadalinstruments.com/glossary/market-structure-shift/)** — A shift is a structure event on one chart. SMT divergence is a comparison across charts. The taught sequence often pairs them: the divergence at the swept extreme first, then a shift on the instrument being traded. - **[Liquidity sweep](https://hadalinstruments.com/glossary/liquidity-sweep/)** — In ICT usage a divergence often appears as a sweep on one instrument that its partner does not match: one pair runs its prior high, the correlated pair stops short. The sweep is an event on one chart; the divergence is the mismatch between two. ## How to measure it in your own data A definition you cannot test is a definition you have to take on trust. This is the shortest honest route from the concept to a number you computed yourself. - **Records you need** — Candle data for every instrument in a declared set, aligned to the same timestamps and timeframe; a stated swing rule for what counts as a prior high or low; and the sign of each pair's relationship, because an inversely related pair confirms by moving the opposite way. - **What you compute** — At each qualifying swing on the reference instrument, look up the time-aligned candle on every other instrument in the set. Flag a divergence when one side trades beyond its prior extreme and the other does not, inverting the test for inversely related pairs. State the alignment tolerance: zero bars is the strict form, and every bar of tolerance admits more near-miss events that are artefacts of the misalignment. - **What the answer tells you** — Two related charts at the same swing: one prints a new high or low, the other stops short of its own. Whether the one that stopped short leads the next move more often than chance and plain correlation allow is the part a measurement has to establish, and the evidence available is thinner than the event count suggests, because correlated instruments are not independent witnesses. ## Questions and answers ### What does SMT stand for in trading? In ICT usage the letters are commonly read as smart money technique. The term names a comparison rather than an indicator: two or more correlated instruments checked for agreement at the same swing. The expansion matters less than the rule, and the rule is what can be checked. ### What is SMT divergence? A moment when correlated instruments disagree at a swing. One trades beyond its prior high or low, and the other, on the same time-aligned candle, does not. The ICT method reads the instrument that refused as showing the real direction. ### What are bullish and bearish SMT divergences? Bullish SMT forms at lows: one instrument makes a lower low while its correlated partner holds a higher low, and the partner that held is read as the stronger side. Bearish SMT is the mirror at highs, one making a higher high while the other stops at a lower high. The reading attached to each is the method's expectation, not a measured result. ### What pairs are used for SMT divergence? Any set whose members normally move together or in mirror. The sets most often taught are EUR/USD with GBP/USD, the S&P 500 and Nasdaq 100 index futures, and the dollar index against the euro pairs, where the relationship is inverse and the test flips. The set is a parameter, and a divergence quoted without its set cannot be checked. ### How does SMT divergence work? Mechanically it is a comparison at time-aligned swings. The account attached to it is that related markets answer to the same flows, so when one refuses to follow the other to a new extreme, the refusal reveals which side is being accumulated or distributed. The account is an interpretation; the comparison is checkable. ### How is SMT divergence different from RSI divergence? RSI divergence sets a price against an indicator calculated from that same price. SMT divergence sets one market's swings against another market's swings. The first is a question about momentum inside one series; the second is a question about agreement between two. ### Is SMT divergence reliable? Harder to measure than it looks. Correlated instruments share most of their movement, so two charts supply far less independent evidence than two separate observations would, and the effective sample behind any hit-rate figure is smaller than the number of flagged events. A reliability figure that ignores that discount overstates what its sample can carry. ## Where it sits in the ICT sequence The ICT vocabulary in the order the method is taught, with a step for each kind of object. - **Step** — 03 of 08 [Liquidity](https://hadalinstruments.com/ict/#step-liquidity): the resting orders, and whether price has taken them - **Also at this step** — [Buy-side and sell-side liquidity](https://hadalinstruments.com/glossary/buy-side-and-sell-side-liquidity/), [Draw on liquidity (DOL)](https://hadalinstruments.com/glossary/draw-on-liquidity/), [ICT daily bias](https://hadalinstruments.com/glossary/ict-daily-bias/), [Liquidity sweep](https://hadalinstruments.com/glossary/liquidity-sweep/), [Inducement](https://hadalinstruments.com/glossary/inducement/), [Judas swing](https://hadalinstruments.com/glossary/judas-swing/), [Turtle soup](https://hadalinstruments.com/glossary/turtle-soup/), [Candle range theory (CRT)](https://hadalinstruments.com/glossary/candle-range-theory/) - **Before it** — [Candle range theory (CRT)](https://hadalinstruments.com/glossary/candle-range-theory/) Liquidity - **After it** — [Break of structure (BOS)](https://hadalinstruments.com/glossary/break-of-structure/) Structure - **Every step** — [The ICT vocabulary map, with every term defined](https://hadalinstruments.com/ict/#vocabulary) ## The shape, drawn The smallest arrangement the definition admits. It is a drawing of a rule, not a reading of a market — nothing here is measured, and the table below it is the authoritative version. FIG. 01 ILLUSTRATIVE Same-candle or not at all. Two aligned series with their swing points compared only where the candles line up — one pair flagged, one left uncompared — and beside them the declared pair set against the evidence it actually carries. Flagging a divergence establishes that two aligned series disagreed at a stated swing. It does not establish that the disagreement predicts anything, and it does not turn a larger pair set into more evidence.
