DSGEX dealer positioning for NDX: three sessions of price with the key levels, beside the exposure ladder by strike

Platform

Structure first.
Signals never.

DSGEX is a desktop app for Windows and macOS that shows real-time options order flow and dealer gamma positioning across 100+ tickers, from SPX and NDX to single names. Every surface describes what dealers and counterparties are doing right now. You decide what to do about it.

Dealer positioning·NDX 0DTE · three sessions

Three sessions of NDX price with the dealer levels: ceiling, apex, gate and floor, resistance and support, and the gamma flip

Dealers Impact on Flow

Two reads of the same dealer chain. Sigils tag each strike with its role (King · Floor · Ceiling · Gatekeeper) and node lifecycle (Fresh · Tested · Delivered · Decaying). Spectrum paints the chain as continuous heat. Call Wall, Put Wall, and Gamma Flip anchor both.

Notable flow rows for QQQ: contract, premium, rank, impact and status

Notable Flow Scanner

Aggressor-signed prints, IMPACT × STATUS tags, sweep / absorbed / late-tape detection.

Volatility drift through one session: implied against realized, with price

Implied vs Realized

Implied against realized, drifting through the session with price. Spot when implied is paying too much for the move.

Three sessions of NDX price, Wednesday to Friday, on the positioning chart

Session Replay

Scrub any past RTH minute. Same flow, same dealer state, same charts as the live day. No archive gaps.

The exposure ladder by strike: net GEX for the day and in total, the spot strike and the pinned levels marked

Key Levels

Walls, gamma flip and magnets anchored to live spot. Grounded in how market makers actually hedge their books.

Implied volatility skew by expiry: every listed expiration on one plot, anchored at spot

Volatility Surface

Skew by expiry, every listed expiration on one plot, anchored at spot. Term structure and the ATM level alongside.

Questions

What is DSGEX?

DSGEX is a desktop app for Windows and macOS that shows real-time options order flow and dealer gamma positioning. It renders every print with its aggressor side, the dealer hedge that print implies, and how spot reacts. It shows mechanics. It never gives trade calls.

What is dealer gamma positioning?

Market makers take the other side of most options trades and hedge the delta of what they hold. Their net gamma decides whether that hedging pushes against price or with it. DSGEX renders that net position by strike and expiry, including the gamma flip, the walls and the magnets.

Which tickers and products are covered?

Listed options on 100+ tickers: index, ETF and single names. SPX, NDX, SPY and QQQ carry the full surface. ES, NQ and GC futures run alongside for order flow.

Is there a free plan?

Yes. The free plan gives thirty minutes of live data a day and needs no card. Pro and Pro+ remove the cap.

Does DSGEX run on Mac?

Yes. There is a native installer for Windows and one for macOS. Download the one for your system, then sign in with your DSGEX account or create one inside the app.

Is DSGEX financial advice?

No. DSGEX is a data and analytics tool. It shows what dealers and counterparties are doing. It does not rank trades, score setups or recommend positions. Options trading involves substantial risk of loss.
