One-timeframing
One-timeframing describes a market in which each time period holds the previous period's low while pushing higher (one-timeframing up), or holds the previous period's high while pushing lower (one-timeframing down). In Market Profile terms it signals that one side is in control of the auction, and it ends at the first period that trades through the prior period's opposite extreme.

Definition
Take consecutive periods, usually the thirty-minute brackets of a day, but the same idea applies to days within a week. The market is one-timeframing up as long as no period trades below the low of the period before it; it is one-timeframing down as long as no period trades above the prior period's high. Definitions differ on whether an equal low breaks the sequence. The first period that violates the rule ends the one-timeframing, which does not mean the move is over, only that the other side has shown up.
A worked example
| Bracket | High | Low | Low above prior low? | State |
|---|---|---|---|---|
| A | 5,010.00 | 5,000.00 | — | Start |
| B | 5,012.00 | 5,003.00 | Yes | One-timeframing up |
| C | 5,011.00 | 5,004.00 | Yes | Still one-timeframing, despite a lower high |
| D | 5,015.00 | 5,006.00 | Yes | One-timeframing up |
| E | 5,015.00 | 5,009.00 | Yes | One-timeframing up |
| F | 5,013.00 | 5,008.00 | No | Ended: F traded below E's low |
What it says about the auction
- Buyers, typically the longer timeframe participants, are willing to pay higher prices every period, and sellers are not able to push through the previous low.
- It is the usual texture of trend days, with value migrating in the same direction as the brackets.
- Pullbacks inside a one-timeframing sequence stay shallow by definition; the first violation is the first sign of two-sided trade.
- It says nothing about how far the move will go, only who has held control so far.
Order flow alongside it
On the footprint, a one-timeframing move up is usually accompanied by delta building in the direction of travel, imbalances stacked on the ask side and pullbacks that meet bids before reaching the previous bracket's low. The period that ends the sequence is worth reading closely: whether sellers took the prior low aggressively, or price simply drifted through it on light volume.
In Senzoukria
The Market Profile (TPO) overlay with 'TPO letters' and 'Split columns' shows each bracket's extremes side by side, and 'Letter colors' can use one color per bracket. On a 30-minute chart, the bars are the brackets. The Higher High / Lower Low indicator is related but stricter: it gives +1 only when both the high and the low are higher, so a bracket like C in the example scores 0 while it still counts as one-timeframing up.

Frequently asked questions
- Does one-timeframing mean a trend day?
- It is one of the characteristics of a trend day, but a session can one-timeframe for a few brackets and then balance. A trend day typically combines one-timeframing with early range extension beyond the initial balance and a close near the extreme.
- What ends one-timeframing?
- A period that trades through the previous period's opposite extreme: below the prior low when one-timeframing up, above the prior high when one-timeframing down. That shows the other side was able to act, and the auction becomes two-sided, at least for that period.
