Options chains: calls, puts, implied volatility and delta
How to read a Quantisnow options chain at /options/<TICKER>: nearest expirations, calls and puts by strike, IV and delta, and how the 15-minute delayed data works.
Key takeaways
- Every optionable U.S. stock or ETF has an options chain page at /options/<TICKER>, for example /options/SPY.
- The page shows the nearest expirations with calls and puts side by side around the current price.
- Each contract shows last price, delta and implied volatility; header stats show average call IV and put IV.
- Data comes from an indicative options feed delayed 15 minutes, and IV and greeks are model-driven.
The options chain page shows calls and puts for a ticker's nearest expirations, with implied volatility (IV) and delta for each contract. Open /options/<TICKER>, for example /options/SPY, or start from /options and pick a symbol.
How to open a chain
- Go to /options and enter a ticker, or click one of the popular symbols.
- Or open
/options/<TICKER>directly. - Or, on any company page, click the Options heading in the sidebar.
If a symbol has no options data on the feed, the page says so.
What the page shows
Header
The header shows the ticker, company name, last price and daily change, and a View TICKER button back to the company page. Below it are summary stats:
| Stat | Meaning |
|---|---|
| Expirations | Number of expiration dates loaded |
| Contracts | Number of contracts loaded |
| Call IV | Average implied volatility across loaded calls |
| Put IV | Average implied volatility across loaded puts |
The chain
Each expiration is its own block, nearest first, labeled with the date, days to expiry, and the count of calls and puts. Inside each block:
| Left side | Middle | Right side |
|---|---|---|
| Call · last · Δ · IV | Strike | Put · last · Δ · IV |
- Last is the last traded price of the contract.
- Δ (delta) is how much the option price is expected to move for a $1 move in the stock.
- IV is the implied volatility priced into the contract.
- Strike rows are centered on the current share price, showing 8 strikes per expiration around the money.
- In-the-money contracts are shown in a brighter color than out-of-the-money ones.

Data source and timing
The chain uses an indicative options feed delayed 15 minutes. IV and greeks are model-driven, so they are estimates, and they can be missing for illiquid strikes (shown as a dash). The page loads the nearest expirations rather than every listed expiration, so far-dated contracts may not appear.
Use this page to understand the shape of a chain, not to time an order. Always check live quotes with your broker before trading.
Options on company pages
Company pages include an Options block with a compact snapshot of the nearest expirations and a link to the full chain. Signed-out visitors see the chain partly blurred with a prompt to sign up; any free account shows it in full. See Company pages.
Tips
- Compare Call IV and Put IV. A large gap can show where traders are paying up for protection or upside.
- Watch IV before scheduled events. IV often rises into earnings or a PDUFA date and falls after. See How to read an earnings report and PDUFA dates explained.
- Pair the chain with news. Follow the ticker and set alerts so you know when a catalyst lands. See Alerts.
