Enhanced Opening Range & Initial Balance

OPR + IB continuously tracks two key intraday ranges — Opening Price Range (OPR) and Initial Balance (IB) — for any configured session.

OPR — high/low over a configurable window at session start (default 15 min, 1–240 min). Sets the initial volatility "footprint" traders use to frame the session.

IB — high/low of a longer opening window (default 60 min, 1–240 min), tracked independently of OPR. Describes the broader early-session range.

OPR and IB levels are not a standalone buy/sell signal. The indicator visualizes the session's structural ranges — the trader interprets them independently.

Sessions: US (9:30 AM–4:00 PM ET), Eurex (2:00 AM–12:00 PM chart time), Asia (8:00 PM–3:00 AM, overnight), Custom — own hours and UTC offset (UTC-12…UTC+14).

Extensions. Three levels (First/Second/Third) above and below each range, own % for each (default 50/80/100%, range 1–500%), independent upper/lower toggles, dashed lines with fading opacity (70→50→30%), optional filled zones.

Rendering. Solid lines at highs/lows, dashed midpoint, labels with exact price at the right edge (background fill for any theme). Smart collision avoidance keeps labels tidy even with 18+ active. IB draws beneath OPR.

Traders can read context from price interaction with the levels: holding above/below a high/low — potential breakout confirmation; return to midpoint after an extension — mean-reversion setup; continuation or exhaustion signs at extensions; OPR/IB levels clustering — confluence zone; comparing OPR/IB widths — range expansion/compression.

Problem It Solves

Manually drawing opening levels is slow, error-prone, and repeats every session. OPR + IB calculates, draws, and extends the ranges in real time, freeing the trader to focus on decisions instead of chart markup.

Key Features

• Dual-range tracking — OPR and IB are independent: own duration, colors, visibility.
• Flexible extensions — 3 levels per range (6 total), own % and toggles for each; any custom scheme.
• Multi-session — US, Eurex, Asia, Custom with UTC offset in one indicator.
• No Fill mode — filled zones or lines only, separately for OPR and IB.
• Smart labels — auto-spacing with no overlap (up to 18+ labels), semi-transparent background, renders above other elements.
• Real-time — tick-by-tick updates, lines extend all session.
• Zero config — works instantly with sensible defaults (OPR 15 min, IB 60 min, US session).

How It Works

At session start, the indicator resets and captures highs/lows during the OPR window (15 min) and, independently, the IB window (60 min); the midpoint is calculated automatically. Once each window closes, levels lock and draw as lines for the rest of the session. With extensions enabled, dashed lines project at the configured %, with optional fill. All labels show exact price without overlap.

Settings

• Session — type (US/Eurex/Asia/Custom), custom hours, UTC offset.
• OPR / IB — show/hide, No Fill, duration (1–240 min), extend lines, colors and line width, labels, fill — configured independently for each range.
• OPR / IB Extensions — % for First/Second/Third (1–500%), upper/lower toggles, opacity, fill — separate for each range.

Example Use Cases

• Breakout. Price holds above OPR High — trader watches the move toward First Extension as a reference.
• Mean-reversion. Price reaches IB High and reverses — trader evaluates a return to the midpoint as a target.
• Session transition. At the US open, the trader checks price against the prior Eurex session's OPR/IB levels.
• Extension targets. After a breakout — 50/80/100% levels as sequential reference points.
• Confluence. OPR High, IB Midpoint, and Second Extension close together — a zone of added attention.
• Range compression. Comparing OPR/IB width — a cue to revisit volatility expectations.
