AlgoStorm Gamma Exposure Levels (GEX-L)AlgoStorm Gamma Exposure Levels (GEX-L)
A high-performance options market structure visualization tool designed to map total Gamma Exposure (GEX) profiles, Call Walls, Put Walls, and Gamma Flips directly onto your charts using custom-pasted external options chain inputs.
The AlgoStorm Gamma Exposure Levels (GEX-L) indicator is designed for active index and futures traders who track institutional options positioning to map structural support, resistance, and volatility inflection boundaries. It translates raw options chain metrics into actionable on-chart structural lines. By default, it supports mapping across SPX (cash index), ES/MES futures, and SPY ETF charts through localized scaling engines.
CRITICAL DATA INPUT REQUIREMENT โ READ BEFORE LOADING
This indicator DOES NOT come with an automatic or built-in options data feed. It operates as a blank visualization engine. To use it, you must copy a standardized 11-value comma-separated (CSV) data string from your external options data provider and paste it manually into the "GEX Data" field inside the indicator settings. The script parses this input to draw static levels for your trading session. It will remain empty until you provide data.
Technical Architecture: Anti-Overlap Stagger Pipeline
Traditional horizontal level indicators frequently suffer from visual clutter and illegible text labels when key options strikes or walls cluster tightly together. To bypass this platform constraint, this script utilizes an advanced multi-array sorting and layout engine:
True Price Isolation: Horizontal level lines are drawn strictly at their accurate options execution strikes, extending across your historical chart data.
Permutation Sorting Pass: The execution engine takes all active inputs and dynamically sorts them from lowest price to highest price on every new market tick.
Algorithmic Staggering Array: A secondary layout pass evaluates the vertical proximity of text tags in your chart margins. If adjacent tags fall below your user-defined point-separation threshold, the text labels are mathematically shifted away from each other along the Y-axis. This ensures that every price label remains completely readable without altering the true location of the price lines.
Features & Functionality
Multi-Tiered Level Layouts: Maps primary macro anchors (Primary Call Wall CW1, Primary Put Wall PW1, and Gamma Flip) using heavy line styling, alongside up to four distinct secondary levels (CW2โCW5 and PW2โPW5) for deeper context into out-of-the-money open interest.
Intelligent Symbol Scaling Engine: Built-in auto-scaling logic bridges index options structure with retail trading instruments. When toggled to SPY mode, the script automatically scales your pasted SPX options data by dividing values by 10 to perfectly align with your ETF chart grid.
Luminance-Sensing Contrast Badges: Features customizable label styles, including a modern solid badge layout. The script calculates the relative luminance of your chosen level colors to automatically determine whether to render black or white text on top of the background badge, preventing visual washout.
Opaque Visibility Overrides: Built with an explicit alpha channel stripping mechanism. Secondary levels can be configured with dimmed, low-opacity line styles to keep your main chart clean, while their text tags remain 100% opaque and sharp inside the margin.
Dynamic Trapped Zone Fills: Renders a background color cloud across the macro zone separating the primary Call Wall and Put Wall. The background dynamically transforms its color state depending on whether the current market price is safely insulated inside the wall boundaries or breaking out into high-volatility territory.
