This article covers the methods for evaluating and monitoring who is in control of the market during the session: one-timeframe versus two-timeframe conditions, auction rotations, the Rotation Factor, timeframe transition, and the recognisable structural patterns of short covering, long liquidation, ledges, and high/low volume areas. This is the core of day timeframe trading strategy — the analysis that runs continuously from the open to the close.

Part I: One vs Two Timeframe Markets
The Fundamental Distinction
All day timeframe market conditions fall into one of two states:
One-timeframe market: One participant (the other timeframe buyer or seller, or the local on a Nontrend day) is in unilateral control. Price auctions in one direction through successive time periods without meaningful counterrotation. Characteristic of Trend days.
Two-timeframe market: Both the other timeframe buyer and seller are active. Price rotates back and forth, with successive periods overlapping rather than extending. Characteristic of Normal, Normal Variation, and Neutral days.
IMPORTANT
Consistent off-floor trading results are most often achieved by trading with the control of the other timeframe participant. You must first identify who is in control, then monitor that control for signs of wavering or reversal.
Identifying One-Timeframe Conditions
In a one-timeframe buying market:
- Each successive time period’s high is higher than or equal to the previous period’s high
- Each period’s low is higher than or equal to the previous period’s low
- No meaningful selling counterrotation interrupts the sequence
In a one-timeframe selling market:
- Each successive period’s low is lower than or equal to the previous period’s low
- Each period’s high is lower than or equal to the previous period’s high
- No meaningful buying counterrotation interrupts the sequence
One-timeframe conditions signal the other timeframe is dominating. The first period that violates the sequence (a higher high in a selling market, or a lower low in a buying market) is the structural signal that control may be shifting.
Identifying Two-Timeframe Conditions
In a two-timeframe market, successive periods overlap each other: B overlaps A on the low side, D overlaps C on the high side, and so on. Neither participant is dominant. Price rotates up and down in a pattern that resembles a horizontal bracket rather than a trending sequence.
Part II: Auction Rotations and the Rotation Factor
Reading Half-Hour Auctions
Each half-hour period is a mini-auction in its own right. By observing how successive periods relate to each other, the trader can track the ongoing battle for control between participants.
The key question for each new period: Does this period extend in the direction of the trend, or does it rotate back? Consecutive extensions in one direction = other timeframe in control. Meaningful counterrotations = control shifting or balance.
The Rotation Factor
The Rotation Factor is a simple, objective scoring system for evaluating day timeframe attempted direction across all half-hour auctions.
How to score:
For each period transition, compare highs and lows:
- If the current period’s high is HIGHER than the previous period’s high: +1
- If the current period’s high is LOWER than the previous period’s high: -1
- If the current period’s high equals the previous period’s high: 0
- Apply the same scoring to lows
Sum all scores for the session.
Interpretation:
| Net Rotation Factor | Reading |
|---|---|
| +6 or higher | Consistent buyer control throughout |
| +2 to +5 | Moderate buyer attempts |
| -2 to +2 | Balanced, two-timeframe trade |
| -2 to -5 | Moderate seller attempts |
| -6 or lower | Consistent seller control throughout |
NOTE
The Rotation Factor only answers the first Big Question: which way is the market trying to go? It does not answer whether the market is doing a good job. A positive Rotation Factor with declining volume and lower value indicates a failing buying attempt.
Time as the Signal
Time is often more informative than structure in real time. Key signals:
Too much time at a level: When price spends multiple periods near the same extreme without extending, something has changed. The participant who was driving may have exhausted their inventory. Watch for transition.
Too little time at a level: Swift movement through a price range = strong other timeframe conviction. Single prints are created. Price will not attract acceptance there — it is excess.
The speed of counterrotation: A counterrotation that develops quickly and extends over multiple periods is more significant than a brief, single-period rotation. The speed of the rotation indicates the level of conviction behind the opposing participant.
Part III: Timeframe Transition
What Transition Looks Like
Most days are not purely one-timeframe or purely two-timeframe for their entire duration. The market transitions between states, and recognising transitions as they develop (rather than after the fact) is what separates good traders from great ones.
Four general categories of transition:
- No transition: One-timeframe (Trend day) or two-timeframe (Normal day) all day
- One-timeframe to two-timeframe: A strong move stalls when it reaches a known reference point (bracket extreme, prior day high/low) — the other side enters and rotates price back into balance
- Two-timeframe to one-timeframe: A balanced, rotational market breaks out decisively in one direction, typically on a balance area breakout or gap
- One-timeframe in one direction to one-timeframe in the opposite direction: Characteristic of a Neutral day, where range extension occurs on both sides
Signals of Transition
Double prints against the one-timeframe direction: When two consecutive periods print above the previous high in a downtrend (or below the previous low in an uptrend), control may be shifting. This creates double TPOs — evidence of time and acceptance at those levels. This is one of the earliest structural signals of transition.
Tail formation against the trend: When a tail forms in opposition to the dominant direction, it indicates aggressive entry by the opposite participant. Combined with double prints, this is strong transition evidence.
Slowing and stagnation: Before a transition is visible in structure, it is often visible in time. If price has been extending in one direction and then slows significantly — spending two or more periods near the same extreme without extending — the transition may be beginning. Structure is slow to show it; time is faster.
The Running Profile
A running profile is a technique for monitoring transitions. When you suspect a transition has begun (after a tail or double print against the trend), start a new profile from that period. Track the successive periods from the potential turning point as a separate mini-profile. If the transition is genuine, the running profile will develop one-timeframe characteristics in the new direction.
Part IV: Structural Patterns
Short-Covering Rallies (P Formation)
What it is: After extended selling, participants become “too short.” A sharp rally occurs, driven not by new initiative buying but by existing shorts covering their positions. The rally is temporary — it lasts only as long as there is short inventory to buy back.
Structural signature: The profile develops the shape of a letter P — a tall upper distribution with no corresponding lower distribution. The upper portion is fat (where the short covering rally spent time), while the lower portion is empty (the gap of the swift rally).
How to identify it:
- Recent market direction has been strongly down
- The open is near the day’s low (short covering often occurs after a gap lower)
- Swift rally early in the day not accompanied by new buying
- Subsequent periods show the buyer losing ground — each period’s auction high is lower than the previous
- Profile develops the P shape
Trading application: Short covering is a market-created selling opportunity. Once the covering is spent and buyers fail to appear, the market typically resumes the prior downtrend and fills in the lower half of the P. Monitor the rally for waning momentum. When the buyer disappears and price begins to auction lower, shorts offer good location.
Long-Liquidation Breaks (b Formation)
What it is: The inverse of short covering. After extended buying, participants become “too long.” A sharp selloff occurs as longs liquidate positions. It lasts only as long as there is long inventory to sell.
Structural signature: The profile develops the shape of a letter b — a lower distribution with no corresponding upper distribution.
Identification: Mirror the criteria for short covering: market direction has been strongly up, the open is near the day’s high, swift selloff not accompanied by new initiative selling, subsequent periods show the seller losing ground.
Trading application: Long liquidation is a buying opportunity. Once longs are fully liquidated, the prior uptrend typically resumes. Monitor for the b formation to fill in upward.
Critical distinction: Short covering and long liquidation are driven by old business adjusting positions, not new initiative participants. Continuation requires NEW initiative participants to enter. If continuation does not materialise, the covering or liquidation completes and the prior trend reasserts.
Ledges
What it is: A half-completed profile — one side of a normal distribution without the corresponding other side. The market repeatedly reaches one extreme and stalls, unable to either resolve back into balance or break through.
Dynamics: Ledges form when the responsive participant repeatedly enters at one price level and cuts off the auction attempt. The market cannot break through the ledge extreme, but also lacks the conviction to fully rotate back into a normal distribution.
Trading application: The ledge is an indication of day timeframe balance at the extreme. A breakout from the ledge in either direction signals a departure from balance. Go with the breakout. If price spills “off the ledge” by more than a few ticks, enter in the direction of the breakout.
Part V: High and Low Volume Areas
High-Volume Areas
What they are: Price regions where a relatively large amount of time was spent and significant volume accumulated during a prior session. Both buyers and sellers were active, creating a short-term balance region.
Properties:
- High volume areas attract price — when price returns to a high-volume region, it will slow
- The slowing creates time: time to enter or exit a trade
- The “memory” of a high-volume area is primarily short-term. The longer price stays away, the less relevant the area becomes
Identification:
- Liquidity Data Bank (LDB): The
%Volcolumn shows percentage of volume at each price. Prices with 8-12% of volume in a cluster are significant high-volume areas - Profile structure: The thick, fat region of the profile at the POC and surrounding prices proxies the LDB data when volume is unavailable
- Tick volume: A reasonable proxy for actual volume
Trading application:
- In an uptrend, if price probes down into a high-volume area, expect it to slow and attract buyers. Use this as a responsive long entry with the trend.
- When exiting a long, a high-volume area above will slow price enough to allow a measured exit.
- Do not try to be perfect — high volume attracts, it does not stop. Price can trade through a high-volume area before accepting or rejecting it.
IMPORTANT
If price builds acceptance (double TPOs) beyond a high-volume area, the area is no longer valid as support. Conditions have changed. Exit immediately.
Low-Volume Areas
What they are: Price regions passed through quickly by the market, with little time spent and minimal volume. Created by the same forces that create tails and excess. Low volume = swift rejection = other timeframe conviction.
Properties:
- Low volume areas represent rejection — the other timeframe rejected prices in that area
- When price returns to a low-volume area, it should face swift rejection again (support or resistance)
- If price builds acceptance (double TPOs) in a low-volume area, that rejection is no longer valid
The balloon analogy: A low-volume area offers resistance like a balloon surface. A probe into it is resisted. Once the probe pierces through, however, there is nothing to stop the motion. When price auctions through a low-volume area, movement is typically swift through the remainder of that area.
Identification: LDB %Vol figures below 1-2% in a cluster indicate low-volume areas. Structurally, single TPO prints and gaps are the profile equivalent.
Trading application:
- Place trades in front of low-volume areas, not inside them — the rejection is swift
- Place stops at the point where price would build acceptance inside the low-volume area
- Low-volume areas often form the boundary between two distributions on a Double Distribution Trend day
Using High and Low Volume Together
The most powerful setups arise when high and low volume areas work together:
Example (down auction):
- Prior session created strong selling with a low-volume area (single prints) in the middle and high-volume area near the lows
- Next session opens near the high-volume area of the prior session
- Rally attempt meets resistance at the bottom of the low-volume area
- Short entry with stop above the low-volume region
- Target: next high-volume area below
Both areas must be continually monitored for change. If price fills in the low-volume area (double TPOs), the resistance is broken and strategy must reverse.
