Multi-Index Gap Confluence Indicator by ATALLA

Overview of the Multi-Index Gap Confluence Indicator
This indicator is designed to identify and highlight price gaps across multiple market indices and their related ETFs/futures. It specifically looks for:

True gaps (where there's no overlap between the current and previous bar's range)
Negative gaps (where only the candle bodies have no overlap, but wicks might)

The indicator has the capability to:

Visualize gaps on charts using colored rectangles
Compare gaps across up to 6 different symbols (3 ETFs and 3 futures)
Generate confluence signals when multiple symbols show gaps simultaneously
Customize appearance and detection parameters

Key Components
Gap Detection
The script distinguishes between:

True gaps: No overlap at all between current and previous bars
Negative gaps: Only the candle bodies have no overlap

Multi-Asset Comparison
The indicator can monitor gaps across six major market indices:

ETFs: QQQ (Nasdaq-100), SPY (S&P 500), and DIA (Dow Jones)
Futures: NQ1! (Nasdaq-100), ES1! (S&P 500), and YM1! (Dow Jones)

Confluence Detection
The script identifies when multiple assets display gaps simultaneously, with:

Configurable minimum threshold (default is 5 out of 6 assets)
Option to require both ETF and futures representation
A strong confluence signal when 5-6 assets show gaps

Customization Options
The indicator offers many parameters for customization:

Gap colors and opacity
Symbol selection and enablement
Confluence thresholds
Display options

Visual Elements
The indicator displays:

Colored rectangles highlighting gap areas
Optional up/down triangles for gap direction
A flag symbol for strong confluence signals (when 5-6 assets show gaps)
Labels listing which specific assets have gaps

Practical Use
This indicator appears designed for traders looking to identify potentially significant market moves by spotting when multiple major indices show price gaps simultaneously. The emphasis on "strong confluence" (5-6 assets showing gaps) suggests these are considered particularly noteworthy signals.
