# One-timeframing One-timeframing is an indicator on [Vela](https://vela.luxalgo.com/chart), our next-generation charting platform, written in Pine Script®. Audits completed periods for one-timeframing (successive bars holding the prior period's opposite extreme) on the chart timeframe and a higher 30-minute bracket. Plots rolling invalidation levels, colors bars, marks sequence breaks, and summarizes state, streak, and level in a dashboard. Built for auction-theory traders tracking who controls the market. - Indicator in the LuxAlgo Library, by LuxAlgo, published Mar 12, 2026. - Access: free. - Concepts: [One-timeframing](https://www.luxalgo.com/library/concept/one-timeframing/) (primary), [Auction Market Theory](https://www.luxalgo.com/library/concept/auction-market-theory/) - Open on Vela: https://vela.luxalgo.com/chart?pineScriptCodeId=tdmw01xixwhvp3azh1hp50bn - Page: https://www.luxalgo.com/library/indicator/one-timeframing/ **One-timeframing** audits completed periods for the auction-theory control test of [one-timeframing](https://www.luxalgo.com/library/concept/one-timeframing/): an up sequence holds every prior period's low, a down sequence every prior high. The audit runs twice (on each chart bar and on a higher timeframe bracket, 30-minute by default, accumulated from chart bars so nothing repaints) and shows as bar coloring, rolling invalidation step lines, break crosses, a bracket background tint, and a dashboard with each audit's state, streak, and invalidation price. ## How to Trade the One-timeframing? - **One-TF Up / One-TF Down**: one side is running the auction. Trade with it rather than fade it. - **Invalidation Level**: the prior period's opposite extreme, rolled forward each completed period: the first trade through it ends the sequence; the natural stop line. - **Break markers**: a cross prints at the violated side; a close beyond upgrades the break from probe to acceptance, each with its own alert. - **HTF background**: the bracket is one-timeframing. Entries against it fight the side in control. Inside periods (holding the extreme without extending the range) tint lighter: the sequence survives but has stalled. Alerts cover starts, continuations, breaks, and accepted breaks on both audits, a staple of the [volume and order-flow family](https://www.luxalgo.com/library/family/volume-orderflow/). ## One-timeframing Settings - **Minimum Sequence Length** (default 2): completed periods before a sequence counts as active. - **Equal Extreme Holds** (default enabled): a period that only matches the prior extreme keeps the sequence alive; disable for the stricter reading. - **Run Higher Timeframe Audit** (default enabled) and **Bracket Timeframe** (default 30). - **Show Dashboard** (default enabled), plus **Position** and **Size**. - Style toggles: **Color Bars**, **Invalidation Level**, **HTF Invalidation Level**, **Break Markers**, **HTF Background**, all enabled by default. ## Frequently Asked Questions ### What exactly ends a sequence? Any trade through the running invalidation level ends it by definition; no close is required. A close beyond the violated extreme upgrades the break to acceptance, and the two cases alert separately. ### How is this different from the Open Types indicator? [Open Types](https://www.luxalgo.com/library/indicator/open-types/) classifies conviction from a session's first minutes; this audit tracks control period by period. The open sets the day's premise, the sequence tells you whether it keeps. ### Which bracket timeframe should I set? The 30-minute default is the classic intraday audit; D audits days within the week, W weeks within a month. Brackets at or below the chart timeframe are marked unavailable on the dashboard. ## Related indicators - [TPO Profile](https://www.luxalgo.com/library/indicator/tpo-profile/) (Auction Market Theory): markdown at https://www.luxalgo.com/library/indicator/tpo-profile.md - [Balance vs Imbalance](https://www.luxalgo.com/library/indicator/balance-vs-imbalance/) (Auction Market Theory): markdown at https://www.luxalgo.com/library/indicator/balance-vs-imbalance.md - [Initial Balance Breakout Signals](https://www.luxalgo.com/library/indicator/initial-balance-breakout-signals/) (Initial Balance): markdown at https://www.luxalgo.com/library/indicator/initial-balance-breakout-signals.md - [Profile Shape Taxonomy](https://www.luxalgo.com/library/indicator/profile-shape-taxonomy/) (Auction Market Theory): markdown at https://www.luxalgo.com/library/indicator/profile-shape-taxonomy.md - [80% Rule](https://www.luxalgo.com/library/indicator/80-percent-rule/) (Volume & Order Flow): markdown at https://www.luxalgo.com/library/indicator/80-percent-rule.md - [Auction Failure](https://www.luxalgo.com/library/indicator/auction-failure/) (Volume & Order Flow): markdown at https://www.luxalgo.com/library/indicator/auction-failure.md - [Value Migration](https://www.luxalgo.com/library/indicator/value-migration/) (Volume & Order Flow): markdown at https://www.luxalgo.com/library/indicator/value-migration.md - [Initial Balance Volume Deficit](https://www.luxalgo.com/library/indicator/initial-balance-volume-deficit/) (Initial Balance): markdown at https://www.luxalgo.com/library/indicator/initial-balance-volume-deficit.md --- Source: https://www.luxalgo.com/library/indicator/one-timeframing/ (LuxAlgo Library).
