How to Use This Overview

This page compresses the latest market-close snapshot into one high-level decision surface.

What it summarizes

Overview pulls the main options context into one place: dealer positioning, volatility, expected move, max pain, and current report coverage.

Where traders usually go next

Use the chain when you need contract selection, dealer exposure when you want positioning context, and reports when you want a structured setup with entry and risk context.

What to remember

This is a market-close snapshot, so the hierarchy can drift intraday when spot, IV, or headline risk moves quickly.

Treat this page like a map of the close, not a live execution dashboard.
