Meet Gexi.
She reads the market makers so you don't have to.

Lexi — Gexi to anyone who's been around more than a week — is an AI persona built around one obsession: what the dealers have to do tomorrow, and how to see it tonight. Every evening she pulls 600 stocks and 11 sectors, maps the gamma walls and the flip, and says it in plain English before the open.

"I don't have a hot take. I have a heat map."

The story

Lexi was the kid who did the math homework for the whole row and got bored halfway through the year. A math degree, a minor in why does everyone in finance talk like that, and a first job in the back office of the back office: a junior quant seat at an options market maker, cleaning dealer-hedging data nobody looked at.

She looked at it.

What she found is the thing this site is built on. Market makers don't have opinions. They have inventory — and inventory has to be hedged. When dealers are long gamma they sell rips and buy dips and the market goes quiet. When they're short gamma they chase, and the market gets loud. Nobody was showing that to regular traders. The people who could see it charged a car payment a month and wrote like a legal brief.

So she got frustrated. Then she got busy. She wrote a program that pulls every options chain after the close, sums dealer exposure strike by strike, and draws the map: where the walls are, where the flip is, where the air pockets sit. Then she pointed it at 600 stocks and 11 sectors and taught it to say which way the money was leaning — before the open, in sentences a human can use.

She kept the program. GEXDesk is the program, with a face.

"Gamma isn't a forecast. It's a weather report on the people who have to hedge no matter what."— GEXI

How she works

  • 01Numbers before adjectives. "Call wall at 585, 40% of open interest" — never "strong resistance."
  • 02Reads, never predicts. Positioning tells you what dealers must do. It doesn't tell you what price will do. She won't pretend otherwise.
  • 03Says what the data can't see. GEX can't tell you why they're hedged. It tells you that they are.
  • 04One joke per piece, max. Usually at Wall Street's expense.
  • 05Free means free. The nightly levels, breadth read and rotation board stay free. Pro gets the full ranking, history and the 7am brief.

What she runs every night

GEX Dashboard nightly

Dealer gamma exposure by strike for SPY, QQQ, IWM and the big names — call wall, put wall, gamma flip, and what positive versus negative gamma means for tomorrow's tape.
Sector Rotation nightly

Eleven sector ETFs ranked by 1-month return against their 3-month rank, so you can see money rotating in and out before it shows up in single stocks.
Pattern Scanner nightly

Thirty liquid optionable names scored on structure, options positioning and momentum, with the top five compression setups surfaced each morning.
Daily Market Setup pre-market

Breadth across 600 stocks, the gamma regime, and the levels that matter — the read Gexi would give you at the bar, one screen before the bell.

The honest part

Gexi is a digital persona operated by GEXDesk. The models, data pipelines and code she "runs" are real and refresh every trading night; the personality is a character. She is not a human, not a licensed financial advisor, and nothing on this site is investment advice or a recommendation to buy or sell any security. Options involve substantial risk of loss. Do your own work, size your risk, and read the privacy & disclaimer page.
