Do I need to trade options for this to be useful?

No. Understanding gamma structure, delta flow, fundamentals, insiders and macro context is useful for traders and investors in the U.S. market even if they do not trade options directly.

What is Gamma Exposure (GEX)?

GEX measures the net gamma exposure of market makers at each strike in the options chain. Positive GEX tends to dampen price moves, while negative GEX tends to amplify them.

What is Net Delta Flow (NDF)?

NDF measures the cumulative net delta of options flow during the session based on monitoring the full stream. Its reading makes it possible to contrast flow and price to detect confirmation, divergence or potential intraday exhaustion.

What is included in the Options Structure section?

The Options Structure section brings together theoretical and applied content to understand gamma, delta, vanna, charm, dealers and hedging. It is designed as a complement to live data and practical analysis.

Does the platform include more than options flow and options data?

Yes. It also includes analyst consensus, price targets, ratios, insiders, macro calendar, yield curve and tools such as a journal and personal tracking depending on your coverage.

Is it available on mobile?

Yes. GEXfocus is available on iOS, Android and WebApp.

What is FEP or Flow Equilibrium Price?

FEP is a synthetic reference that summarizes the equilibrium price of flow during the session. It is used to interpret intraday bias, liquidity zones and the current position of the underlying relative to accumulated flow.

ATdesdecero is now GEXfocus. The same platform, now with a brand more focused on options flow, GEX, gamma levels, NDF and intraday structure.

Proprietary indicators built to read flow, bias and intraday exhaustion.

NDF and FEP are indicators developed by GEXfocus to interpret underlying movement through the options market. NDF follows delta flow throughout the session by monitoring the full options flow stream, while FEP summarizes the equilibrium price of that flow as a reference for bias and liquidity zones.

Each can be used independently, but the combined reading provides much more context: NDF helps detect confirmation or divergence between flow and price, while FEP shows where the asset is trading relative to its intraday equilibrium. Their best performance usually appears in indices, where 0DTE liquidity and options chain depth allow for a more consistent reading.

Theory and concepts to understand the mechanics behind flow.

The options structure section clearly summarizes the logic behind dealers, hedging, gamma, delta, vanna and charm. It is not meant as isolated theory, but as a layer that helps you better interpret what you later see in live data.

The goal is to connect concepts with real application. From compression and acceleration zones to directional sensitivity and time pressure, everything is designed to complement operational reading and reduce blind spots.

Gamma and walls

How hedging levels can act as braking zones, magnets or acceleration points for spot price.

Delta and directional flow

A clearer reading of when flow supports, diverges from or starts losing strength against price.

Vanna, charm and volatility

Useful concepts for better interpreting IV changes, time decay and mechanical pressure.

Applied theory

Condensed content built to connect structure, live data and execution inside the same ecosystem.

GEXfocus ebook

Dive deeper into the mechanics that actually move price.

The ebook explores in greater detail the logic of hedging, gamma exposure, the role of dealers and the impact of Greeks such as delta, vanna and charm on spot price. It also covers GEX, Gamma Flip, walls, NDF, volatility, trading scenarios, risk management and the integration of structure with technical analysis within a practical framework.

It is designed to complement the platform with a deeper layer of applied theory without losing operational focus.

Options analysis, market structure and fundamental context with GEXfocus

GEXfocus, formerly ATdesdecero, is an options analysis and market structure platform designed for traders and investors looking for more context than the chart alone can provide. It brings together Gamma Exposure, Put/Call Wall, Net Delta Flow, 0DTE data, fundamentals, insiders, macro calendar and WebApp access in one environment.

The platform offers options data with fast updates throughout the session, making it possible to track net gamma, dealer pressure and key levels before price fully reflects that context. This is useful both for pre-market analysis and intraday execution.

Within that framework, GEXfocus also includes proprietary indicators such as NDF and FEP to follow delta flow, intraday equilibrium and divergences between hedging and price. Their best performance usually appears in indices, where 0DTE liquidity and options chain depth allow for a more consistent reading.

In addition to live data, GEXfocus includes an options structure section focused on understanding how gamma, delta, vanna, charm and market maker hedging can influence spot behavior. Theory and practice are connected within the same ecosystem.

The environment is completed with MCP integration for Claude, custom TradingView indicators, macro calendar, fundamentals, insiders and personal tracking tools. The goal is not to offer a single tool, but a more complete and less fragmented analysis architecture.
