Fish Orb

This indicator marks and tracks the first 15-minute range of the New York session open (default 9:30–9:45 AM ET) — a critical volatility period for futures like NQ (Nasdaq).
It helps you visually anchor intraday price action to that initial opening range.

Core Functionality
1. Opening Range Calculation

It measures the High, Low, and Midpoint of the first 15 minutes after the NY market opens (default 09:30–09:45 ET).
You can change the window or timezone in the inputs.

2. Visual Overlays

During the 15-minute window:
A teal shaded box highlights the open range period.
Live white lines mark the current High and Low.
A red line marks the midpoint (mid-range).
These update in real-time as each bar forms.

3. Post-Window Behavior

When the 15-minute window ends:
The High, Low, and Midpoint are locked in.
The indicator draws persistent horizontal lines for those values.

4. Historical Days

You can keep today + a set number of previous days (configurable via “Previous Days to Keep”).
Older days automatically delete to keep charts clean.

5. Line Extension Control

Each day’s lines extend to the right after they form.
You can toggle “Stop Lines at Next NY Open”:
ON: Yesterday’s lines stop exactly at the next NY session open (09:30 ET).
OFF: Lines extend indefinitely across the chart.
