FreeOpen sourcePine Script v6
Plot PDH, PDL, PWH and PWL from completed prior-day and prior-week data, then register how the current day or week interacts with each boundary. Examine Untested, Contacted, Sustained beyond and Re-entered states, post-contact residency/excursions, and daily-weekly range geometry in one chart register.
PDH and PDL are the raw high and low of the completed previous day; PWH and PWL are the raw high and low of the completed previous week. The script does not calculate a pivot ladder, classify support/resistance, predict direction, choose a target or produce entries and exits. It records confirmed interaction with each boundary.
Four color-coded boundary lines, prior-day/week ribbons, their shared corridor, nearby high/low pair highlighting, retained historical segments, first-contact or full-lifecycle marks, collision-managed right-edge tags and a Boundary Response Register containing price, state, distance, response and range-geometry context.
Completed higher-timeframe values are requested with a one-period offset, so each active boundary stays fixed during its corresponding day or week. Contact can use wick range, candle body or confirmed close-to-close span plus optional tolerance. Consecutive confirmed closes beyond a boundary create Sustained beyond; a later confirmed return into the prior range creates Re-entered.
PDH, PDL, PWH and PWL are not pivot-formula, midpoint or equilibrium levels. A daily and weekly boundary at similar prices remain related references from the same market series, not independent confirmations.
Untested means no confirmed contact; Contacted records the first one; Sustained beyond requires consecutive confirmed closes outside; Re-entered records a later confirmed return into the corresponding prior range. None predicts what follows.
OUT/X reports outside-close residency and close-side recrosses; MAX O/I reports maximum outside and inside excursions. Shared corridor, nearby pairs and hull position describe price geometry, not probability, win rate or strength.
Add the public script to a time-based intraday chart or the 1D chart. Under the defaults, identify PDH, PDL, PWH, PWL, the day/week ribbons, right-edge labels and Boundary Response Register before changing one input at a time.
Open the public PDH PDL PWH PWL Boundary Response Register page and add it to a TradingView chart. It uses completed daily and weekly data for boundaries and commits lifecycle events on confirmed chart bars. No SG Group account is required.
Overlapping lines, bands, backgrounds or tables can be duplicate drawings of the same kind of information. Never treat visual overlap by itself as stronger evidence or signal agreement. Another previous-day/week high-low study, session extremes, pivots, opening ranges, support/resistance lines, horizontal drawings or alerts can duplicate PDH, PDL, PWH, PWL, historical segments, ribbons, event marks, right-edge tags and the register. Merged or displaced tags do not change exact boundary prices.
Do not begin by labelling a horizontal boundary as support, resistance or a target. Verify data source, boundary price, contact definition, four-stage lifecycle, post-contact measurements and cross-horizon geometry in that order.
PDH/PDL remain previous-day values throughout the current day; PWH/PWL remain previous-week values throughout the current week. Check whether Reference data uses standard candles or the modified chart context.
Do not read Untested, Contacted, Sustained beyond or Re-entered without checking wick/body/close-span contact, tolerance and required closes. Different definitions can classify the same chart differently.
Residency, recrosses, excursions, contact separation and range overlap describe the active source period. They are not historical probabilities, win rates, expectancy, entries or targets.
High / low of the completed previous day; fixed during the active current day.
High / low of the completed previous week; fixed during the active current week.
No confirmed contact under the selected definition / first confirmed contact recorded.
Required confirmed closes stayed outside / a later confirmed close returned into the prior range; neither is predictive.
Outside-close residency percentage / confirmed close-side recross count after first contact.
Maximum outside excursion / maximum return into the prior range, normalized by frozen daily ATR.
Day/week high or low pair is within tolerance / prior ranges share a mathematical intersection; not support/resistance.
The labels below match the published script’s English Inputs panel. Defaults reflect the public source at the time of review and may change in a later TradingView update.
On small screens, each input is reformatted as a readable stacked card.
| Input label | Default / options | What it controls and when to adjust it |
|---|---|---|
Reference data | Automatic / options: Automatic, Chart context, Standard candles | Automatic uses the chart context on standard charts and standard-candle data on non-standard charts. Chart context preserves chart modifiers. Standard candles removes non-standard chart calculations and other ticker modifiers. |
Show previous-day high and low | On | Shows, hides or enables show previous-day high and low. Start with the published default and change one input at a time. |
Show previous-week high and low | On | Shows, hides or enables show previous-week high and low. Start with the published default and change one input at a time. |
Keep completed period segments | On | Keeps prior daily and weekly line segments on the chart for historical study. Disable this to retain only the active day and week. |
Daily periods kept | 30 / min 1, max 120 | Controls daily periods kept. Start with the published default and change one input at a time. |
Weekly periods kept | 16 / min 1, max 52 | Controls weekly periods kept. Start with the published default and change one input at a time. |
Daily ATR length | 14 / min 1, max 100 | Uses the last completed daily ATR value for normalized distances and optional tolerance calculations. |
Allow lifecycle events on non-standard charts | Off | Levels remain available on non-standard charts. Lifecycle events, current-range progress, and related alerts are paused by default because synthetic bar construction can make event timing ambiguous. Enable only for explicit research use. |
| Input label | Default / options | What it controls and when to adjust it |
|---|---|---|
Contact definition | Wick range / options: Wick range, Candle body, Close-to-close span | Wick range checks the confirmed bar's high-low span. Candle body checks the open-close span. Close-to-close span checks whether consecutive confirmed closes straddle the level, including a gap when the two closes lie on opposite sides. |
Contact tolerance | Exact / options: Exact, Ticks, Daily ATR | Controls contact tolerance. Start with the published default and change one input at a time. |
Tolerance in ticks | 0 / min 0, max 1000 | Controls tolerance in ticks. Start with the published default and change one input at a time. |
Tolerance as daily ATR | 0.02 / min 0, max 1, step 0.01 | 0.02 means 2% of the last completed daily ATR. |
Closes required beyond | 2 / min 1, max 10 | A level enters Sustained beyond only after this many consecutive confirmed closes beyond it. This state is independent of direct wick/body contact, so a gap can qualify. It is descriptive, not a trade signal. |
Reflect lifecycle in line style | On | Untested levels use their selected base style. Contacted levels become dashed, Sustained beyond levels become emphasized, and Re-entered levels become dotted. |
| Input label | Default / options | What it controls and when to adjust it |
|---|---|---|
Track post-contact response | On | After a boundary's first confirmed contact, records outside-close residency, close-side recrosses, maximum outside excursion, maximum return into the prior range, the first-contact form, and lifecycle timing. These are descriptive measurements, not trade signals. |
Excursion measurement | Wicks / options: Wicks, Closes | Wicks uses confirmed bar highs/lows for maximum excursions. Closes uses confirmed closing prices. Outside-close residency always uses confirmed closes. |
| Input label | Default / options | What it controls and when to adjust it |
|---|---|---|
Highlight nearby day-week pairs | On | Highlights PDH near PWH and PDL near PWL. It does not classify a cluster as support or resistance. |
Cluster threshold | Daily ATR / options: Daily ATR, Ticks, Percent | Controls cluster threshold. Start with the published default and change one input at a time. |
Threshold as daily ATR | 0.12 / min 0, max 2, step 0.01 | 0.12 means the two levels are treated as nearby when their separation is no more than 12% of the last completed daily ATR. |
Threshold in ticks | 25 / min 0, max 100000 | Controls threshold in ticks. Start with the published default and change one input at a time. |
Threshold in percent | 0.1 / min 0, max 10, step 0.01 | 0.10 means 0.10% of the two compared levels' mean absolute price. |
High-pair highlight | rgba(255,235,59,1) | Sets the display color for high-pair highlight. It changes presentation only, not boundary prices or measurements. |
Low-pair highlight | rgba(64,255,218,1) | Sets the display color for low-pair highlight. It changes presentation only, not boundary prices or measurements. |
Highlight transparency | 91 / min 70, max 98 | Controls highlight transparency. Start with the published default and change one input at a time. |
Show shared prior-range corridor | On | Highlights only the price interval shared by the previous completed daily range and the previous completed weekly range. This is a geometric overlap reference, not a support/resistance classification. |
Shared-corridor color | rgba(82,255,255,1) | Sets the display color for shared-corridor color. It changes presentation only, not boundary prices or measurements. |
Shared-corridor transparency | 95 / min 80, max 98 | Controls shared-corridor transparency. Start with the published default and change one input at a time. |
| Input label | Default / options | What it controls and when to adjust it |
|---|---|---|

PWL color | rgba(255,171,0,1) | Sets the display color for pwl color. It changes presentation only, not boundary prices or measurements. |
Daily line width | 3 / min 1, max 5 | Controls daily line width. Start with the published default and change one input at a time. |
Weekly line width | 4 / min 1, max 5 | Controls weekly line width. Start with the published default and change one input at a time. |
Add active-level contrast halo | On | Draws a chart-background-colored outline beneath the four active levels. The outline stays on the symbol's main price scale and improves separation from candles, grids, and range shading. |
Halo width addition | 2 / min 1, max 4 | Controls halo width addition. Start with the published default and change one input at a time. |
Halo transparency | 12 / min 0, max 70 | Lower values create a stronger separation outline. The outline automatically follows the chart background color. |
Dim completed period segments | On | Keeps historical study context while making the four currently active levels visually dominant. |
Completed-segment transparency | 58 / min 0, max 95 | Controls completed-segment transparency. Start with the published default and change one input at a time. |

| Input label | Default / options | What it controls and when to adjust it |
|---|---|---|
Show right-edge level labels | On | Shows, hides or enables show right-edge level labels. Start with the published default and change one input at a time. |
Right-label content | Code only / options: Code + price, Code only, Code + lifecycle | Code only is the compact default. Exact prices and lifecycle details remain available in the Boundary Response Register and label tooltips. |
Right-label horizontal placement | Responsive / options: Responsive, Fixed bars | Responsive converts a percentage of the currently visible bar count into the future-bar offset, keeping a more consistent screen-space distance as horizontal zoom changes. Fixed bars uses only the minimum/fixed offset below. |
Responsive offset as visible width (%) | 8 / min 2, max 25, step 0.5 | Approximate share of the visible bar count reserved between the latest bar and the annotation rail. The result is capped below Pine's 500-bar future-drawing limit and never falls below the minimum offset. |
Stagger daily and weekly rail anchors | On | When enabled, weekly annotations use a second horizontal anchor lane. Responsive placement can enlarge the gutter as the visible bar count increases. |
Merge nearby day/week labels | On | When PDH is within the configured proximity threshold of PWH, or PDL is near PWL, the two chart tags collapse into PDH/PWH or PDL/PWL. Exact prices, states, and separate horizontal levels remain unchanged and are preserved in the tooltip and register. |
Minimum / fixed right-label offset | 12 / min 4, max 200 | Minimum future-bar distance used by Responsive placement, or the exact distance used by Fixed bars placement. |
Daily-weekly rail stagger | 4 / min 1, max 20 | Minimum additional future bars between daily and weekly anchor points. Responsive placement can enlarge this gutter in proportion to the visible bar count. |
Auto-separate close rail labels | On | Resolves every active right-edge tag in one collision set, including merged pairs and cross-group labels. Exact boundary prices and horizontal lines remain unchanged. Optional leader segments identify displaced tags. |
Minimum rail-label gap as daily ATR | 0.3 / min 0, max 2, step 0.05 | Minimum visual separation between nearby display tags, expressed as a fraction of the last completed daily ATR. |
Minimum rail-label gap in ticks | 12 / min 0, max 10000 | Tick-based floor for automatic rail-label separation. The larger of this value and the ATR-based value is used. |
Scale-aware rail-label spacing | On | Adds a spacing floor derived from the highest and lowest visible chart bars. The script recalculates this floor when the visible window changes, so label separation adapts when the chart is scrolled or zoomed. |
Minimum rail-label gap as visible range (%) | 6 / min 0, max 20, step 0.25 | Minimum display-anchor separation as a percentage of the visible bars' high-low range. The final gap is the largest of this value, the daily-ATR floor, and the tick floor. |
Show displaced-label leaders | On | Draws a short dotted segment between the exact boundary price and a display tag that was shifted vertically. Merged pair tags can receive one leader from each exact boundary. |
Right-label size | Large / options: Tiny, Small, Normal, Large, Huge | Controls right-label size. Start with the published default and change one input at a time. |
Historical event marks | First contact / options: Off, First contact, Full lifecycle | First contact marks only the first confirmed contact per level and period. Full lifecycle also marks the first Sustained beyond and first Re-entered event. |
Event-mark content | Symbol only / options: Symbol only, Symbol + code | Symbol only is the cleaner default. Colors identify PDH, PDL, PWH, and PWL, while tooltips preserve the full event description. |
Event marks kept | 90 / min 10, max 450 | Controls event marks kept. Start with the published default and change one input at a time. |
Event-mark size | Normal / options: Tiny, Small, Normal | Controls event-mark size. Start with the published default and change one input at a time. |

Register size | Compact / options: Compact, Balanced, Presentation, Custom | Compact is the default and is designed to preserve chart space while keeping every visible cell bold and high contrast. Balanced adds moderate size. Presentation restores the large publication-oriented scale. Custom unlocks the three point-size inputs below. |
Custom body text size (pt) | 13 / min 9, max 26 | Used only when Register size is Custom. All visible register text remains bold. |
Custom column text size (pt) | 14 / min 10, max 28 | Controls custom column text size (pt). Start with the published default and change one input at a time. |
Custom title text size (pt) | 16 / min 12, max 32 | Controls custom title text size (pt). Start with the published default and change one input at a time. |
Register font | Default / options: Default, Monospace | Default uses the system's proportional chart font and generally appears heavier. Monospace remains available for fixed-width numerical alignment. |
Register background | rgba(0,3,9,1) | Sets the display color for register background. It changes presentation only, not boundary prices or measurements. |

| Input label | Default / options | What it controls and when to adjust it |
|---|---|---|
Enable combined dynamic alert() | Off | When enabled, confirmed lifecycle, completed contact-pair, and response-threshold events on the same bar are combined into one alert() message. Create the TradingView alert using Any alert() function call. |
Minimum response observations | 4 / min 1, max 100 | Minimum confirmed post-contact observations required before an outside-close residency threshold can trigger. |
Outside-close residency threshold (%) | 75 / min 0, max 100, step 1 | Triggers once per boundary and source period when the outside-close share reaches this threshold after the minimum observation count. |
Outside-excursion threshold (ATR) | 0.5 / min 0, max 20, step 0.05 | Triggers once per boundary and source period when maximum outside excursion reaches this many frozen daily ATR units. |
Alerts report confirmed contact, sustained-beyond, re-entry, nearby day/week pairs, completed contact pairs and configured response thresholds. They do not instruct a trade or forecast continuation, reversal, target or stop.
This tool is for analysis and visualization. It is not investment advice, a trade recommendation, a forecast, or a promise of profit or accuracy. Results depend on inputs, symbol, timeframe, and data feed. You remain responsible for every trading decision.
PDH, PDL, PWH, PWL and normalized ATR come from completed higher-timeframe periods and stay fixed during the active source period. Current distance, developing day/week range use and current-period extremes can change intrabar.
PDH/PDL lifecycle resets on every new daily bar. With more than one required close, multi-close Sustained beyond for daily boundaries is mainly meaningful on intraday charts. Weekly boundaries can still accumulate daily closes.
One chart bar can contact several boundaries without proving tick order. Events confirmed on the same bar are simultaneous at chart resolution unless the available data proves otherwise.
Holidays, early closes, exchange or broker feeds and ticker modifiers can change completed-period OHLC. Lifecycle evaluation is paused by default on synthetic charts. Only time-based intraday and 1D charts are supported.
Boundaries, nearby pairs, shared corridor, lifecycle, OUT/X, MAX O/I and hull position are related descriptions derived from the same price series and active periods. Do not count coincidence as independent evidence or relabel it as support, resistance, liquidity, reversal, continuation, entry, target, stop or probability.
Clarify fixed boundary timing, four lifecycle states, post-contact response, the 1D limitation, non-standard charts and moving display labels.
Yes. It is a free, open-source indicator published by SG Group on TradingView. Review TradingView’s terms and the conditions attached to the public script before reuse or redistribution.
Start with the published defaults and observe the drawings and state changes first. Then change one input at a time for the symbol, timeframe and data feed so you can identify what caused each visual change.
Yes, but similar lines, bands, backgrounds and tables can overlap and obscure their source. Isolate each indicator first and hide duplicate components. Visual overlap alone is not stronger evidence or signal agreement.
No. It is analysis and visualization context consistent with the public description. It does not provide entries, exits, targets, stops, price forecasts, or promises of profit, win rate or accuracy.
The four boundaries use one-period-offset completed daily and weekly data, so they stay fixed during the corresponding current day or week. Current distance, developing range use and visual tag positions can still change with realtime price or viewport changes; those are not boundary-price revisions.
This guide is grounded in SG Group’s live catalogue, the script’s published TradingView description, and the user-facing inputs in its open source. Labels and defaults can change after a script update.
