AG Pro PDH PDL PWH PWL Engine [AGPro Series]

Overview / What it does

AG Pro PDH PDL PWH PWL Engine is a price-reference overlay built to track prior day, prior week, and prior month high / low levels in a clean and structured way. The script can display PDH, PDL, PWH, PWL, and optionally PMH / PML, together with midpoint equilibrium levels for the selected ranges.

The main purpose of the script is not to predict direction, generate guaranteed entries, or replace a complete trading plan. Its role is narrower and more practical: it helps traders keep important prior-period reference levels visible on the chart, distinguish which levels remain active, and identify which ones have already been traded through. In many markets, prior highs and lows are widely monitored as liquidity, reaction, and reference areas. This script organizes those areas into a format that is easier to read in live conditions.

A core design goal of this tool is chart hygiene. Many prior-level indicators become visually noisy when several daily, weekly, and monthly references are drawn together. This script was designed to keep the structure readable by using a minimal label system, right-extended lines, a swept / unswept state model, and an optional dashboard that summarizes the nearest active daily, weekly, and monthly levels.

The result is a workflow-oriented overlay that helps with context. Instead of forcing interpretation through aggressive signals, it presents a structured map of where important prior-period levels are located, whether they are still untouched, and whether current price is approaching one of them. That makes it suitable for traders who want an objective level engine rather than a directional prediction tool.

Unique Edge

The script focuses on presentation quality and state clarity rather than simple level plotting. Prior highs and lows are not rare concepts, but the practical usefulness of such levels depends heavily on how they are filtered, displayed, and maintained on the chart. This script aims to improve that usability in several ways.

First, it separates active levels from swept levels. This matters because a previously untouched level and a level that has already been traded through do not carry the same contextual value for many traders. By visually differentiating unswept and swept references, the overlay can help reduce ambiguity when reviewing current structure.

Second, it combines multi-period references in one coherent engine. Daily, weekly, and optional monthly levels can all be displayed together, while preserving a relatively clean visual hierarchy. This is particularly useful for traders who want to see whether current price is interacting with short-term references inside larger higher-timeframe ranges.

Third, it includes proximity logic. The script can highlight levels when price is near them using a threshold defined in ticks, percentage, or ATR terms. This does not imply a trade signal by itself. Instead, it acts as a situational awareness feature that helps traders notice when price is entering a predefined level zone.

Fourth, the script offers session and timezone controls. That allows the user to adapt the level-building logic to the exchange clock or to a chosen session definition. For traders who care about session-based construction and consistency across instruments, this can be an important operational detail.

Finally, the panel is designed as a compact summary rather than a decorative feature. It reports the nearest active daily, weekly, and monthly references, shows counts for active and swept levels, and keeps session / timezone / label mode settings visible. The goal is to reduce chart scanning time and make the script easier to use during live analysis.

Methodology

The engine tracks highs and lows from completed prior periods and then projects those values forward as reference lines. Depending on the enabled settings, it can build:

- Previous Day High and Previous Day Low
- Previous Week High and Previous Week Low
- Previous Month High and Previous Month Low
- Optional equilibrium midpoints for each enabled range

Each level is created only after the relevant source period is completed. In that sense, the level itself is based on completed historical range data. Once created, the line is monitored for its state. If price trades through a high reference or a low reference, the script marks that level as swept and changes its visual treatment accordingly.

The script also maintains historical periods up to the number defined in the settings. This makes it possible to preserve a limited amount of recent structure without keeping an unlimited number of stale objects on the chart.

The equilibrium option adds the midpoint of the corresponding prior range. Some traders use these 50% areas as balance references or as secondary context between the prior high and low. Because that midpoint is optional, the user can keep it visible when needed or disable it for a cleaner chart.

The proximity engine measures how close current price is to an active level using one of three methods:
- Tick distance
- Percentage distance
- ATR-based distance

This feature is meant to flag nearness, not to define trade quality on its own. A prior level being near price does not automatically make the setup actionable. It only states that price is close to a tracked reference according to the selected threshold logic.

States / Signals / Alerts

This script is primarily a level-state and context tool. It is not a directional forecasting model. Its most important outputs are state-based:

1) Active level
A level is considered active when it has been created from a completed prior period and has not yet been traded through by price.

2) Swept level
A level is considered swept when price trades through that reference. Visually separating swept levels from active ones helps the chart communicate which prior references remain untouched.

3) Near-level condition
When enabled, the script can highlight active levels that are close to current price according to the user-defined threshold method. This can help traders focus attention on nearby reference zones without scanning the entire chart manually.

4) Compact dashboard state
The panel summarizes the nearest active daily, weekly, and monthly levels, along with active count, swept count, near count, selected timezone, session configuration, and label mode.

The included alert conditions are intentionally simple and state-based:
- Price is near one of the active levels
- At least one tracked level was swept on the current bar

These alerts are meant to support monitoring. They are not, by themselves, a complete trading trigger. Users should interpret them together with structure, volatility, session context, confirmation rules, and their own risk process.

Why this script can be useful

This script can be useful because prior highs and lows often matter most when they are easy to monitor and hard to misread. In practice, traders do not only need the raw numbers; they need a chart presentation that allows those numbers to remain readable during fast market conditions.

A clean prior-level map can help in several common situations:
- Evaluating whether price is approaching an untouched daily or weekly reference
- Checking whether a local move is happening inside a larger higher-timeframe level framework
- Distinguishing still-relevant references from already-tested ones
- Monitoring potential reaction zones without crowding the chart with excessive objects
- Organizing reference structure across intraday and swing workflows

The script is also designed to remain practical over time. Instead of drawing everything with equal visual importance, it uses state logic and summary logic to keep the display more structured. That can make the tool easier to integrate into a routine where prior-period references are part of the trader's contextual process.

Another useful aspect is that the script stays objective. It does not attempt to label every market move with a strong opinion. It shows completed prior-period levels, their current state, and whether price is approaching them. Many traders prefer this kind of neutral reference framework because it can be combined with other methodologies without forcing one interpretation.

Key Inputs

Timezone
The script can use the exchange timezone or a selected timezone. This affects how period transitions are interpreted.

Use Custom Session Filter
When enabled, highs and lows are built only from bars inside the selected session. This allows the user to adapt the range construction to a chosen session framework.

Session
Defines the custom session window when session filtering is enabled.

Show Previous Day / Week / Month Levels
Each group can be enabled or disabled independently so the user can decide how much structure to display.

Show Equilibrium Midpoints
Adds the 50% midpoint of each enabled prior range.

Historical Periods to Keep
Controls how many past periods remain visible on the chart for each enabled level family.

Proximity Threshold Type
Lets the user define nearness by ticks, percentage, or ATR.

Threshold Value / ATR Length
Controls the sensitivity of the proximity logic.

Highlight Levels When Near
Allows visual emphasis when price approaches an active level.

Line Style and Extension Settings
Controls the appearance of unswept and swept lines and whether active lines extend to the right.

Minimal Label Mode
Allows labels to be turned off, restricted, or shown for active levels, depending on the user's preferred chart cleanliness.

Panel Controls
The dashboard can be enabled or disabled and its size, position, and colors can be adjusted.

Example use cases

This script can be used in different ways depending on the trader's workflow.

Intraday context mapping:
A trader may monitor PDH and PDL together with PWH and PWL to understand whether intraday price is moving into untouched daily liquidity while still operating inside a broader weekly range.

Reaction-zone awareness:
A trader may use near-level highlighting to notice when price is approaching an unswept prior high or prior low and then look for separate confirmation with their own method.

Structure filtering:
A trader may ignore swept references and focus mainly on active levels that remain intact, especially when trying to simplify the chart during live sessions.

Session-based reference building:
A trader who prefers a specific session logic can use the session filter so the constructed ranges better match their market framework.

Dashboard monitoring:
A trader may use the panel as a quick situational summary to identify which daily, weekly, or monthly reference is closest without manually reading every line.

Limitations & Transparency

This script does not know why price interacts with a level. It only identifies prior-period references and tracks whether they are active, near, or swept according to the rules defined in the code.

A prior level is not automatically support or resistance in every market condition. Some reactions are meaningful, some are shallow, and some levels are passed through with little response. For that reason, the script should be treated as a structured reference map rather than a self-sufficient trade decision engine.

The near-level logic depends on user-defined thresholds. Different threshold types and values can materially change how often levels are classified as near. Traders should calibrate these settings according to instrument volatility and their own workflow.

Session and timezone choices also matter. The same market can produce different prior-period values depending on how the session is defined. Users should select settings that match the way they analyze the instrument.

Historical object limits, chart timeframe, and chart compression can influence how dense the display appears. A setting that looks clean on one instrument or timeframe may feel crowded on another. The script provides controls to manage that, but users should still adapt it to their own use case.

The midpoint equilibrium lines are optional because not every trader uses 50% references the same way. Their inclusion does not imply that the midpoint has universal predictive value. It is simply provided as an additional structural reference.

This script is intentionally conservative in what it claims. It does not claim to detect institutional intent, hidden order flow, or guaranteed reversals. It displays prior completed reference levels and their current state on the chart.

Risk Disclosure

This script is for chart analysis and educational use. It does not provide financial advice, investment advice, or trade recommendations.

Prior-period highs, lows, and midpoint references can be useful market context, but they are not guarantees of reaction, reversal, continuation, or liquidity behavior. Market conditions can change quickly, and price can move through any level without producing a tradable setup.

Users should combine this tool with their own confirmation process, execution rules, position sizing framework, and risk management. No indicator should be used as the sole basis for entering or exiting a trade.

Before using any chart tool in live markets, it is important to understand how its settings affect output, how it behaves on the instrument being traded, and how it fits into a broader decision process.

AG Pro PDH PDL PWH PWL Engine is designed to help organize prior-period level information in a cleaner and more operational format. Its value comes from clarity, state tracking, and context support, not from predictive certainty.

Release Notes

Update Notes - V1.3

This update focuses on visual refinement, structure clarity, and day-to-day usability across previous day, previous week, and previous month reference levels.

The core level engine remains centered on PDH, PDL, PWH, PWL, PMH, and PML logic, while the presentation layer has been revised to reduce clutter and improve chart readability in active market conditions.

What changed in this update:

1) Cleaner default chart presentation
The default layout has been revised to reduce unnecessary visual density on the right side of the chart. Level distribution, label behavior, and event visibility have been adjusted so the script can remain informative without overwhelming the price action.

2) Improved hierarchy between daily, weekly, and monthly structures
The visual priority of the level sets has been refined. Major higher-timeframe references now read more clearly relative to nearby daily references, and equilibrium levels are handled in a more controlled way so the chart keeps a stronger structural hierarchy.

3) Better equilibrium handling
Equilibrium midpoint logic was cleaned up and separated more clearly from standard high/low level behavior. This helps prevent midpoint references from feeling over-emphasized or visually competing with the main structural levels.

4) Reaction and sweep presentation refinements
Sweep and reaction-related markers were revised to be more selective and more readable. Event display behavior was adjusted to avoid excessive repetition and to keep the emphasis on the most relevant visible interaction.

5) More compact and organized event display
The event layer now behaves in a more restrained manner, especially around clustered price areas. This improves legibility when multiple important references exist in a tight price region.

6) Active range visualization added and refined
An active range zone was introduced and then polished to create a clearer visual anchor between key reference levels. The range display was adjusted to act more like a subtle structural band rather than a heavy chart object, helping the script feel more integrated with price rather than overlaid on top of it.

7) Reduced visual noise from historical structures
Older or less relevant structures now step back more cleanly in the visual hierarchy. This allows current active references to remain the primary focus when scanning the chart.

8) Premium label treatment for line references
Right-edge level labels were redesigned to look more like compact UI tags instead of plain text markers. This gives the active levels a more finished and readable appearance while preserving quick identification.

9) Better label spacing and overlap control
Label cluster behavior was improved so nearby references are less likely to stack in a distracting way. Spacing logic was adjusted to preserve readability when multiple levels are active in the same area.

10) Refined panel behavior
The panel remains compact and chart-friendly, with the established AG Pro header format preserved. The information shown is focused on what is immediately useful: nearest key levels, active and swept counts, and the most recent relevant event state.

11) Stronger chart usability in live conditions
The script was adjusted with practical chart use in mind, not just static screenshots. The goal of this update was to improve structure reading during active price development while keeping the output visually disciplined.

12) No change to the main purpose of the script
This remains a reference-level mapping tool built to track and monitor previous day, previous week, and previous month high/low areas together with their equilibrium context and interaction states. The update is focused on cleaner execution, clearer presentation, and more balanced information delivery.

General note:
This update is designed to improve readability, structural clarity, and visual consistency. It does not change the script into a prediction model or automated trading system. The script continues to function as a chart analysis and reference tool.

As always, level interaction should be interpreted within the broader chart context, timeframe structure, and individual risk process.

Release Notes

Update Notes - Version 1.4

This update keeps the script in its original prior-period levels family while making the chart presentation more polished, more readable, and more useful for fast context scanning.

What changed:

- Public title branding has been cleaned up to match the current AGPro Series release format. The public script title now keeps the original PDH PDL PWH PWL Engine identity and the [AGPro Series] suffix without the leading AG Pro prefix.

- The active range visualization has been upgraded into an Active Range Corridor. Instead of only showing a static band, the corridor now adapts its color to the current pressure state around the selected prior-period range.

- A new Range Pressure readout was added to the panel. It classifies the active corridor as Balanced, Upper Drift, Lower Drift, Upper Pressure, Lower Pressure, Above Range, or Below Range so traders can understand where price is sitting inside the active prior-period structure at a glance.

- A subtle Equilibrium Pocket has been added inside the active corridor. This keeps the visual layer concept-native and helps separate balance-area behavior from edge pressure without turning the script into a generic support/resistance zone tool.

- The panel has been rebuilt with the standard AGPro blue merged header row. The first row is a single merged row with only the script name, and panel location plus theme controls are available from settings.

- Label and panel defaults have been refined for a more premium chart appearance. Label font size and panel font size remain adjustable, with Normal used as the default.

- Event labels are still intentionally capped and spaced. Sweep, hold, reject, and optional equilibrium flip markers are kept compact so the chart has useful activity without becoming crowded.

- Professional English tooltips were added across the settings to make each control easier to understand for public users.

- A new alert condition was added for Active Range Pressure Shift events, allowing users to monitor changes in the active corridor state.

- Code structure was cleaned up for the public release pass, including safer array cleanup patterns, clearer helper functions, reduced visual noise, and updated AGPro palette usage.

Screenshot polish pass:

- Default historical depth was reduced so the first public view focuses on the most relevant recent prior-period levels instead of filling the chart with older horizontal references.

- Weekly and monthly levels now sit more quietly in the background by default. This keeps higher-timeframe context available without letting distant PWL/PML lines dominate the visual composition.

- Level labels now start farther to the right of price and use stronger cluster spacing so they are less likely to sit inside candles or overlap each other around PDH/PDL reaction areas.

- Touch and reaction counts were moved behind an optional setting. The default label style is cleaner for publication screenshots, while advanced users can still enable count details from settings.

- Visible event labels are capped more tightly by default. Sweep and reaction events remain available, but the chart now avoids stacked clusters when several prior-period levels are interacted with in the same area.

- All chart labels now follow the same Label Font Size setting. Level tags, sweep labels, hold/reject labels, and optional equilibrium flip labels are controlled from one label-size input for consistent visual scaling.

- The active corridor border was made slightly clearer while keeping the fill restrained, so the corridor reads as a premium context layer rather than a heavy support/resistance block.

Differentiation:

This update does not reposition the script as a general key-level dashboard, a session reaction tool, or a previous-day sweep-and-reclaim signal script. Its role remains narrower: prior day, prior week, and prior month reference levels with active corridor context and structured reaction awareness.

The new Active Range Corridor and Range Pressure layer are designed to make the script visually stronger while keeping it distinct from other AGPro Labs publications that focus on session reactions, sweep-reclaim events, or broader key-level suites.
