(Fri Range

Core Function:
Weekly Friday Range - Captures the entire Friday's trading range (from midnight to midnight NY time)

Extended Display - Shows that range for 6 more days (through next Thursday)

25%/75% Levels - Adds support/resistance levels at the 25% and 75% points of the Friday range

Swing Detection - When price breaks out of the Friday range, it finds and marks the most recent swing point that led to that breakout

Key Visual Elements:
DR Range (Daily Range): Friday's high and low

IDR Range (Inside Day Range): Friday's opening range (between open and close)

Opening Line: Friday's opening price

25%/75% Lines: Support/resistance levels within the range

Swing Lines: When breakout occurs, draws horizontal lines from the swing point that preceded it

Why It's Useful:
1. Weekly Context
Shows how Friday's trading activity sets up the following week

Provides a weekly "anchor point" for traders to reference

2. Breakout Analysis
When price breaks above/below Friday's range, it shows where the move started from (the swing point)

Helps identify if breakouts are genuine or false

3. Support/Resistance Levels
The 25%/75% levels act as natural support/resistance within the range

These often become targets or reversal points

4. Multi-Timeframe Perspective
Combines daily (Friday), weekly (range extension), and swing (violation) analysis

Shows how short-term swings relate to weekly ranges

5. Trading Applications:
Range Trading: Trade bounces between 25%/75% levels and range extremes

Breakout Trading: Enter when price breaks the range, target the swing level

Reversal Trading: Fade moves at swing levels after range violations
