Northsea Auction Map [JOAT]

Northsea Auction Map [JOAT]

Introduction

Northsea Auction Map is an open-source auction-style overlay that builds a rolling or session-anchored profile directly on the chart. It estimates where business has been conducted, where value is concentrated, where activity is thin, and how price is positioned relative to that structure.

The problem this script solves is that directional tools alone do not explain where the market is accepting price and where it is rejecting price. Auction context is useful because trend and reversal behavior both depend on where price is trading relative to value. Northsea uses a configurable anchor, builds a profile histogram, derives value area and point of control, approximates delta bias, and summarizes that information in a clean on-chart framework.



Core Concepts

1. Session or Rolling Anchoring

The script can build its auction map from a live session anchor or from a fixed rolling window. That allows it to serve both intraday session analysis and broader window-based contextual analysis. Session anchoring can use exchange-aware timing or an explicit timezone selection so the profile starts from the intended session definition.

2. Profile Row Construction

The chosen anchor range is divided into configurable price rows. Each eligible bar contributes volume into those rows, producing a simplified volume-at-price map. The widest concentration becomes the point of control, while the surrounding rows are expanded outward until the configured percentage of activity defines the value area.

3. Point of Control and Value Area

Northsea calculates:

• POC: the highest-activity row
• VAH: the upper boundary of the selected value area
• VAL: the lower boundary of the selected value area

These levels are drawn forward on the chart so users can quickly see whether price is trading inside accepted value or outside it.

4. Delta Bias and Node Logic

The script derives a directional participation proxy and combines it with profile concentration to estimate whether the current map leans more bid-dominant, offer-dominant, or balanced. It also classifies high-value nodes and low-value nodes using row-level z-score logic so pockets of acceptance and low-participation gaps stand out.

5. Anchored VWAP and Range Context

An anchored VWAP and session range lines are drawn alongside the profile. This gives the user both price-distribution context and mean-location context in the same overlay.

Features

• Two anchoring modes: Session Anchor and Rolling Window
• Flexible session timezone handling: Supports exchange-aware or explicit timezone session anchoring

• POC and value area: Automatically derived and extended on the chart
• HVN and LVN identification: Highlights acceptance nodes and thin areas
• Anchored VWAP: Adds a fair-value style reference line
• Session range guides: High, low, and midpoint lines
• Delta bias proxy: Adds directional auction context
• Dashboard summary: Anchor bars, range, POC/VWAP, value area, delta bias, location, and balance metrics

How to Use This Indicator

Step 1: Locate Price Relative to Value
If price is trading inside the value area, the market is operating near accepted value. If price is outside value and not returning quickly, the market may be discovering a new area.

Step 2: Compare POC With VWAP
The relationship between POC and anchored VWAP can help show whether the bulk of business and the weighted mean price are clustered together or diverging.

Step 3: Watch HVNs and LVNs
High-value nodes often behave like acceptance shelves. Low-value nodes often behave like traversal zones where price moves more quickly. These are not guaranteed reactions, but they are useful structural references.

Step 4: Use the Delta Bias as Context, Not Certainty
The delta bias proxy helps describe whether the current map is leaning more bid-side or offer-side. It should be read as auction context rather than treated as direct order-book truth.

Indicator Limitations

• The script approximates auction structure from bar data and does not reconstruct true exchange-level volume at every traded price
• Profile interpretation depends on the selected anchor; different anchors can produce different maps
• Thinly traded instruments may generate unstable row distributions
• Node thresholds are model-based and may require tuning by instrument

Originality Statement

Northsea Auction Map is original in the way it combines anchored profiling, value-area construction, node classification, delta bias estimation, and anchored VWAP into one restrained overlay. The goal is not to duplicate a platform-native profile panel, but to provide a configurable auction context tool that can travel with the chart and integrate directly with other analytical layers.
