How does the free trial work?

Your first Pro subscription starts with a 7-day free trial. You enter a card at checkout and aren't charged until the trial ends. Cancel during the trial and you pay nothing; Pro ends right away.

Can I cancel anytime?

Yes, from your account page. Pro stays on until the end of the month or year you've paid for, then the account goes back to Free.

How fresh are the numbers?

On Pro the price streams trade by trade and the levels are worked out again at that price. The option chain behind them refreshes about every 60 seconds for the ticker you're viewing, and every minute all session for SPX, SPY, QQQ, and IWM. Free shows the latest snapshot for SPX, SPY, QQQ, and IWM, refreshed in place. Without an account you see the last close.

What does connecting your AI mean?

Theta Vantage works as a connector in Claude, ChatGPT, and other AI apps that support MCP. You add it once and sign in with your Theta Vantage account; there's no API key to copy. The app can then ask for levels, charts, and the other tools your plan opens: 42 on Free and 47 on Pro. Apps that show interactive views draw the same charts as the site.

Which tickers can I use?

Free covers SPX, SPY, QQQ, and IWM. Pro covers any stock, ETF, or index with listed options: type it in the search and its page fills in. The first time anyone opens a ticker takes a few seconds.

Is this financial advice?

No. Theta Vantage shows information about the options market, and Athena's answers are information too. The terms of service say more.

25% off your first 3 months of Pro, or your first year on yearly, with FALL25, through Nov 6.

For a first Pro subscription. The 7-day free trial comes first.
