Overview
Not every session behaves the same way. Mind Over Markets groups days into a handful of recognizable day types, defined by how the initial balance develops and how far value migrates. You can't know the day type in advance — but recognizing which one is forming early tells you whether to fade the edges or hold for a trend.
Think of them as the market's personalities. The read isn't "predict the day"; it's "notice, by the second or third bracket, which personality showed up, and stop trading against it."
The six day types
| Day type | What it looks like | What it means / how to lean |
|---|---|---|
| Normal day | Wide initial balance set early by longer-timeframe traders; little range extension after. A fat, contained bell. | The day stays inside its opening range. Rotational — value-edge fades tend to work. Relatively rare. |
| Normal variation day | Moderate IB, then range extension on one side (roughly up to the size of the IB). The most common day. | One side gains the upper hand mid-session. Lean with the extension once it's accepted; the opposite IB extreme holds. |
| Trend day | Narrow IB, then value migrates steadily one direction all session; shallow pullbacks; a tall, thin profile. | An other-timeframe participant is in full control. Do not fade. Hold with the trend; buy pullbacks (or sell rallies). |
| Double-distribution trend day | Quiet, rotational open, then a decisive move to a new area — leaving two separate bells joined by thin single prints. | The market rejected the first area and accepted a new one. Trend behavior; the single-print "spike" between the two often acts as support/resistance. |
| Neutral day | Range extension on both sides — buyers and sellers each pull price beyond the IB. Indecision. | Two-timeframe fight, no winner. "Neutral-center" close (near the middle) = true indecision; "neutral-extreme" close (at one end) = late resolution toward that side. |
| Non-trend day | Very quiet and narrow — little range, low conviction, minimal extension. Often ahead of a major news event. | Coiled energy. Low opportunity intraday, but frequently precedes a larger move; a break of the tight range can be significant. |
The through-line: IB width + how far value migrates = the day type. Narrow IB with strong migration → trend; wide IB with none → normal/rotational; extension both ways → neutral; almost nothing → non-trend.
Using day types in practice
- ·Form a hypothesis early, hold it loosely. By the second or third bracket, ask: narrow or wide IB? Extending, and which side? That narrows the likely type.
- ·Let the type pick the playbook. Rotational types (normal, non-trend, neutral-center) reward fading; trend types reward holding with the move.
- ·Update as it develops. Days morph — a quiet open can become a double-distribution trend. Re-read each bracket; don't marry the first guess.
Honest assessment
Strengths
Day types turn a vague feeling ("today's trending") into a named, checkable pattern tied to concrete features (IB width, extension, value migration). They're a fast filter for the one decision that matters most intraday: fade or follow.
The honest limits
They're descriptive labels, applied in hindsight. A day only becomes "a trend day" once it has trended; early on, several types are still possible. The categories blur, days convert from one to another, and the framework is tuned to a classic single-session (futures) structure — it fits 24-hour and overlapping global markets less cleanly. Use them to shape probabilities and avoid obvious mistakes, not to predict the close.
Evidence rating: a well-known, practical taxonomy widely used by auction traders. Its value is disciplined pattern-recognition and risk framing, not forecasting — always confirmed as the day unfolds.
Practice
Quiz 1 — What most distinguishes a trend day early on?
A narrow initial balance followed by steady value migration in one direction with shallow pullbacks. The tell is that the opening range was small and price kept accepting new levels away from it.
Quiz 2 — What defines a neutral day?
Range extension on both sides of the initial balance — buyers and sellers each pushed beyond it. It signals indecision; where it closes (center vs. extreme) hints at whether it resolved.
Quiz 3 — Why can't you know the day type at the open?
Because the type is defined by how the day develops — IB width and value migration. You recognize the forming pattern bracket by bracket and adjust; you never know it in advance.
