Introduction to Theta Vantage

What Theta Vantage computes, who it's for, the three places you can use it, and what each plan opens.

Theta Vantage estimates how options dealers' hedging could push a stock or an index, and draws the prices where that hedging gathers on the chart. For SPX, SPY, QQQ, IWM, and any ticker with listed options, it adds up dealer gamma, vanna, charm, and delta across every strike and expiration, then names the levels that come out of that math: the call wall, the put wall, zero gamma, max pain, and the expected move.

Around those levels sit the tools an options trader reaches for during the week: the option chain, a strike selector for premium sellers, a wheel and income planner, a strategy calculator, options flow and net premium drift, IV rank and the historical move, and company pages and the earnings calendar.

Why "Theta"

Theta is the greek for time decay: what an option loses each day as expiration gets closer. Premium sellers are paid by it, which is why the wheel, covered calls, cash-secured puts, and credit spreads all start from it. The strikes that pay a seller are often the strikes where dealer hedging gathers, so the product puts the two side by side.

Who it's for

• Options traders who already use dealer levels. You trade index options, liquid ETFs, and the busier single names, from the same day to a few weeks out, and you want the walls, zero gamma, and the expected move before the open and during the session.
• Premium sellers. You sell puts, covered calls, or credit spreads and want strikes checked against the implied move, the historical move, how often price has reached them before, and where dealer gamma sits.
• Stock traders who watch the options market. You don't trade options much, but you want to know where hedging could slow a move down or speed it up.
• Traders who work inside an AI app. You ask Claude, ChatGPT, or another assistant about markets and want positioning answers there, with the same charts. See Connect your AI.

You'll get the most out of it if calls, puts, strikes, and expirations are familiar. The glossary covers the rest, from open interest to the wheel.

Three places, one set of numbers

• On the web. Each ticker has its own pages: the overview at /SPX, focus pages for each panel, and the options tools. They work on a phone too.
• In Athena. Athena answers questions in plain words with the same numbers, and shows each answer's charts as the pages draw them.
• In your AI app. Add Theta Vantage to Claude, ChatGPT, Cursor, or another app that takes connectors, sign in, and ask there. See Connect your AI.

A level is computed once and served everywhere, so SPX's call wall on the page, in Athena, and in your AI app is the same number with the same time.

Plans

• Without an account you see SPX, SPY, QQQ, and IWM at the last close: the levels, the gamma profile, and the key-levels strip.
• Free shows those four tickers at the latest snapshot, adds exposure by strike, the heatmap by expiration, max pain, the expected move, the option chain, IV rank, company pages for any stock, three Athena questions a day, one watcher, and your AI app.
• Pro opens any ticker with listed options, every view and expiration filter, live updates, options flow and drift, and more of everything else.

Pages and plans lists every page with what each plan opens, and pricing has the prices.

Where to start

1. Open SPX and read the key-levels strip across the top.
2. Read Dealer positioning and the levels for what each level means and how it's computed.
3. Pick the tool for your trade: the strike selector for a short put, the strategy calculator for a spread, or watchers to be told when price reaches a level.

Everything here is information about the market, not advice. The terms say so in full. Options carry real risk of loss, and the numbers describe an estimate of dealer positioning, which can be wrong.
