This article covers the central framework of Jim Dalton’s Markets & Momentum: the relationship between Market-Generated Information (MGI) and momentum as the two complementary lenses for reading the market. It explains how each indicator behaves, why they diverge, how traders exploit momentum patterns, and how to combine both for the highest-probability reads. The article also includes Dalton’s real 2024 trading examples that illustrate how this framework operates under live market conditions.
Part I: The Framework
Leading and Lagging Indicators (Markets & Momentum)
Dalton opens with a direct reversal of conventional wisdom: momentum is the leading indicator, and MGI is the lagging indicator.
- Momentum leads because it is simple to execute. It requires no structural context, no volume reading, no value analysis. The majority of short-term traders use it. That simplicity means momentum-driven moves happen quickly, and the “expected” response to any price move is momentum continuation.
- MGI (Market Profile-based analysis: price, time, volume, structure) lags because it is complex. Building a full structural picture takes time. Context develops over 30-minute periods, not seconds. But MGI is objective. It tells you what the market is actually doing, rather than what traders think it is doing.
IMPORTANT
Neither MGI nor momentum is inherently superior. They are complementary. The edge comes from reading both simultaneously and identifying their degree of confluence or divergence.
The Three Confluence Scenarios
| Scenario | Implication | Trading approach |
|---|---|---|
| MGI and momentum in sync | Highest confidence; market is healthy with good odds of continuation | Go with the move; monitor for continuation |
| MGI and momentum showing mild divergence | Odds initially favour momentum continuation; MGI is a delayed reaction | Stay with momentum; monitor MGI closely for resolution |
| MGI and momentum showing significant divergence | Counter-auction activity high; momentum is likely running on old inventory | Expect a reversal or stall; wait for structure confirmation |
NOTE
When there is conflict between momentum and MGI, the expected (momentum) response is more likely in the short term because it is the simpler, faster action most traders take. However, an expected response that is not backed by MGI (volume, healthy structure) will be limited in duration, with higher odds of retracement.
Why the Divergence Exists
When momentum traders drive a move that is not supported by fundamental market structure, they are essentially creating inventory imbalance. Price moves quickly; value moves slowly. A price advance on weak volume, with a truncated or unhealthy Profile, signals that the commitment behind the move is low. MGI, as the lagging indicator, eventually “catches up” and the price reverts toward developing value.
The delay between the momentum-driven move and the MGI reaction is where most trading losses occur. Traders who only see momentum assume the move is real. Traders who read MGI can identify the divergence earlier and position accordingly.
Part II: Reading MGI
Volume Relative to Direction (Markets & Momentum)
The most fundamental MGI signal is volume in the context of price direction.
| Condition | Implication |
|---|---|
| Higher prices + increasing volume | Healthy advance; buyers are committed |
| Higher prices + decreasing volume | Weakening advance; buyers losing conviction |
| Lower prices + increasing volume | Healthy decline; sellers are committed |
| Lower prices + decreasing volume | Weakening decline; sellers drying up; higher odds of reversal |
NOTE
This relationship is always more complex than stated. Volume alone is insufficient. It must be read within the context of the developing Profile structure, the current trend timeframe, and existing inventory conditions.
Profile Shape and Health
Dalton uses a “Goldilocks” framing for Profile health:
- Too elongated: Emotionally charged market. Emotional decisions are usually unreliable. High odds the move is liquidation or short covering rather than new money.
- Too truncated: Lack of interest or counter-auction activity. Risk/reward is not in the trader’s favour.
- Just right: Balanced participation, sustainable move, developing conviction.
An overly elongated Profile on a directional day often signals a “p” or “b” shape (short covering or long liquidation respectively) rather than meaningful new-money activity. This is a crucial distinction for assessing continuation odds.
Value Development
Value moves slowly; price moves fast. Watching the relationship between developing value areas is how traders assess whether a move has genuine follow-through:
- Value building higher day over day: buyers in control, trend is healthy
- Value overlapping (neither higher nor lower): market seeking balance
- Value unchanged or declining while price advances: dangerous divergence; price has gotten ahead of value
The rate of POC migration through the session is also informational. A POC migrating consistently in the direction of the auction signals healthy directional conviction. A stagnant POC despite directional price movement suggests the advance is price-only, not value-driven.
p and b Formations as MGI
The “p”-shaped Profile signals short covering: the market became too short to go lower. Short sellers must buy back, creating temporary upward pressure.
The “b”-shaped Profile signals long liquidation: the market became too long to go higher. Long holders are exiting, creating downward pressure.
IMPORTANT
A short-covering rally that clears short inventory can weaken the market. Once the covering is complete, the buying force disappears. Momentum traders who attribute this rally to new-money buying may take inventory from “too short” directly to “too long,” setting up the next directional break.
Non-Excess Highs and Lows
Excess marks the end of one auction and the beginning of another. Non-excess highs and lows are ambivalent: the market has not clearly rejected that price level.
- Non-excess high: odds are good the market will eventually revisit that level; the lack of rejection increases the probability of upside continuation
- Non-excess low: same logic inverted for downside
- Weak high or low (within one tick of a previous reference): signals weaker-timeframe trader activity, lower odds of endurance
Tracking non-excess levels from prior sessions and carrying them forward is a key component of Dalton’s “carrying information forward” framework.
Tempo as Advanced MGI
Tempo is the speed or pace at which market activity progresses. It cannot be taught directly; it must be acquired through experience.
| Tempo condition | Implication |
|---|---|
| Slowing tempo with the trend | Directional activity may be pausing; possible inventory rebalancing |
| Slowing tempo against the trend | Potential “call to action”; offers or bids drying up against prevailing direction; often signals coming reversal |
| Fast tempo in one direction | Higher odds the move is liquidation or short covering rather than new money |
New money from institutional participants is generally slow and consistent. Rapid acceleration usually indicates short covering or long liquidation. “Serious new money sellers are holding many other securities and it’s not in their best interests to destroy the market.”
Part III: Momentum Traps
Pied Piper Syndrome (Markets & Momentum)
Dalton’s term for the predictable collective behaviour of short-term traders: “Traders do what works until it doesn’t work anymore.”
When a pattern (selling late in the session, fading every rally, buying every dip) produces consistent results over several sessions, traders collectively adopt it. This creates a recognisable inventory imbalance that more experienced participants exploit. The trap is set when the majority of short-term traders have positioned the same way at poor prices.
Short-in-the-Hole
“Short in the hole” means the market is short at bad prices. Once inventory accumulates heavily on one side, short-term strength is paradoxically created: all those shorts must eventually buy to cover, and all those longs must eventually sell to exit.
The cycle:
- Short-term traders get too short (often through Pied Piper momentum selling)
- Slowing downward tempo signals buying pressure building beneath the surface
- Short-covering rally begins; appears to be buying momentum
- Momentum traders pile in long as the rally extends
- Market goes from too short to too long
- The same short-term traders who just covered shorts now sell into the rally
- Market rolls over; the inventory cycle repeats
IMPORTANT
The move from “too short” to “too long” through a short-covering rally is one of the most common patterns in short-term trading. Momentum traders who misread covering as new-money buying repeatedly fall into this trap.
FOMO as Momentum Amplifier
FOMO (Fear of Missing Out) is the emotional driver behind momentum extremes. It is most likely triggered by:
- Sharply rising prices in bull markets
- Sharply falling prices in bear markets
- Unexpected news events
- Short squeezes and liquidation events
- Social media hype
- Front-running of economic releases
FOMO causes traders to enter positions at poor locations, exacerbating inventory imbalances and creating the very fuel that eventually reverses the move. When FOMO drives a market through a reference level (yearly high, bracket extreme), experienced traders recognise that buyers are emotionally committed, not structurally committed.
Part IV: Applying the Framework
January 8-11, 2024: Divergence During a Rally
On December 28, 2023, the S&P established a non-excess high at 4,840. From January 8-10, momentum re-emerged and the market rallied. The conflict: the Profile was thin from low to high, and January 8 showed multiple distributions, suggesting the early 2024 selling was primarily liquidation, not new-money selling. MGI was flagging a short-covering rally, not a genuine advance. The market confirmed this on January 11 with a sharp retracement.
Key read: multiple distributions with thinness from low to high = liquidation, not new money. Short covering rallies weaken the market once the covering inventory is cleared.
February 5, 2024: Emotional Failure Despite Correct MGI
Bonds gapped lower Monday morning. Dalton’s MGI read was correct: the equity market opened near the centre of Friday’s range, signalling a rotational day. Value confirmed a balancing session. But Dalton was carrying a Friday loss and was cognitively anchored to expecting lower equity prices. Despite correct MGI, emotional and ego factors drove incorrect execution.
Key read: this example illustrates that MGI correctness is necessary but not sufficient. Emotional capital and psychological discipline determine whether correct MGI translates into correct execution.
February 13, 2024: Tempo as Call to Action
The Dow dropped more than 700 points. Short-term traders were selling en masse following a hot inflation print. The afternoon of February 13 presented a slowly decelerating tempo on the downside. The market was becoming “too short” but the only signals were: (1) unusually slow downward tempo and (2) price sitting just above the January 31 high.
Buying into a 700-point decline based on tempo alone is “technically correct and well communicated via slow tempo, but felt nearly impossible.” This is the gap between knowing MGI and acting on it.
March 26-28, 2024: Pied Piper in Three Acts
For three consecutive sessions (March 21, 22, 25), short-term traders sold late in the session. By March 26, they did it again. This is the Pied Piper trap: the pattern worked for three days, so traders committed to it on the fourth. On the 26th, H, I, J, K, and L period highs were almost identical (matching highs = mechanical, weak, short-timeframe sellers). By day’s end, inventory was dangerously short.
March 27: Momentum traders saw the prior day’s decline and sold again from the opening. Late session, the shorts from multiple prior days plus the new shorts from the 27th morning were all caught in the hole simultaneously. A massive short-covering rally erupted in K period.
March 28: Early “p”-shaped rally (short covering only, not new money) reduced continuation odds. Non-excess high on the 27th. Two consecutive non-excess lows on the 28th in H and I periods. Final result: late liquidation ended the session. The Pied Piper cycle was complete.
