An options chain is a wall of numbers: dozens of strikes, two sides, and columns for bids, asks, volume, open interest, implied volatility and Greeks. Most of it doesn't matter for the question you have. The skill is knowing which few numbers answer it, and an assistant with the data can find them and do the arithmetic.
With Equibles connected to ChatGPT or Claude, the assistant can list expirations, read a chain, open a single contract and compare what options are pricing with what the stock has actually done. This guide works through six prompts on Nvidia, which reports its fiscal third quarter on Tuesday, November 17, after the close. Every answer below is real tool output from November 10, 2026, around 1 p.m. Eastern Time.
Before you start
Connect the Equibles MCP server to your assistant once: ChatGPT setup or Claude setup. After that, the assistant picks the right tool on its own; you never type a tool name. Live bids and asks need a paid plan; the free plan sees end-of-day data.
1. Which expiration covers the report?
When does Nvidia report next, and which option expirations fall just before and just after it?
The assistant calls GetUpcomingInvestorEvents for the date and GetOptionExpirations for the list:
- Report: Tuesday, November 17, after the close, with the call at 5:00 p.m. Eastern.
- Last expiration before it: Monday, November 16.
- First expiration after it: Wednesday, November 18, then Friday, November 20.
This matters more than it looks. An option expiring on the 16th can't be affected by the report; one expiring on the 18th carries the whole reaction. Comparing the two isolates what the market is paying for the event.
2. What does the chain look like around today's price?
What is Nvidia trading at right now? Show me the November 18 calls and puts at the three strikes closest to that price, with bid, ask, implied volatility, delta, volume and open interest.
GetLiveQuote puts Nvidia at $167.13 at 12:51 p.m. Eastern, down from $178.67 at Monday's close and $206.69 a week earlier. GetOptionChain returns the November 18 strikes around it:
- 165 call: bid 10.20, ask 10.40, implied volatility 90.9%, delta 0.57.
- 165 put: bid 7.55, ask 7.75, implied volatility 90.9%, delta -0.43.
- 167.50 call: bid 8.90, ask 9.10, implied volatility 90.3%, delta 0.53.
- 167.50 put: bid 8.75, ask 8.90, implied volatility 90.1%, delta -0.47.
- 170 call: bid 7.70, ask 7.90, delta 0.49, volume 5,052 against open interest of 18.
- 170 put: bid 10.00, ask 10.30, implied volatility 89.7%, delta -0.52.
Delta is roughly how much the option's price moves for a $1 move in the stock, and near 0.5 means the strike is close to the money. Implied volatility near 90% is very high for a company of Nvidia's size, and it is high because the report sits inside this expiration. The chain is also on Nvidia's options page.
3. What does one contract tell you?
Open the November 18 $167.50 call. What are its bid and ask sizes, its range today, and its theta and vega?
GetOptionContract gives the full snapshot:
- Quote: bid 8.90 for 248 contracts, ask 9.10 for 57, last trade 8.92.
- Today's range: 8.50 to 11.61, on 839 contracts. On Monday it closed at 17.00, when the stock was $11 higher.
- Theta: -0.56, so with nothing else changing it loses about 56 cents of value a day.
- Vega: 0.099, so each point of implied volatility is worth about 10 cents.
A 20-cent spread on a $9 option is tight. Far from the money, spreads widen, and the price you see in a "last" column can be hours old.
4. How big a move are options pricing?
Using the strike closest to the current price, add the November 18 call and put mid prices. What move does that imply as a percentage of the stock price? Do the same for November 16.
The assistant uses the chain from step 2:
- November 18 (after the report): 9.00 + 8.83 = $17.83, or 10.7% of $167.13.
- November 16 (before the report): 5.58 + 5.43 = $11.00, or 6.6%, with implied volatility near 64%.
The at-the-money straddle, a call plus a put at the same strike, is the usual shorthand for the move the market is pricing by expiration. Both expirations include the days before the report, so most of the gap between them, about $6.80 for two extra sessions and a jump in implied volatility from about 64% to 90%, is what the market charges for the report.
5. How does that compare with what Nvidia has done?
On each of Nvidia's last seven earnings reports, how much did the stock move from the report-day close to the next day's close? And what is its 14-day average true range?
The assistant takes the report dates from ListInvestorEvents and the closes from GetStockPrices:
- February 2025: down 8.5%
- May 2025: up 3.2%
- August 2025: down 0.8%
- November 2025: down 3.2%
- February 2026: down 5.5%
- May 2026: down 1.8%
- August 2026: up 8.7%
That is 4.5% on average in either direction, and 8.7% at most. GetAverageTrueRange adds context: the 14-day average true range was $8.39 on November 9, about 4.7% of the price, up from $6.42 on November 3. Its typical daily range lately is already wider than its average report-day move, though a range and a close-to-close move are different measures; that recent turbulence is part of why the options are expensive. Seven reports is a small sample, so read this as scale, not a forecast.
6. What is the wider market doing with options?
What has the CBOE equity put/call ratio been over the last month?
GetPutCallRatios gives the daily figures: 0.56 on November 9 and 0.59 on November 6, after 0.89 on November 5, the highest reading since mid-October. Since October 13 it has ranged from 0.44 to 0.89. A ratio well under 1 means more calls than puts trade across US stocks; the spike on November 5 was the day the VIX jumped, a reminder of how quickly hedging demand appears.
Put it together in one prompt
Nvidia reports on November 17 after the close. Using live prices, find the first expiration after the report and the last one before it, read the at-the-money straddle on both from the strike nearest the current price, convert each to a percentage move, and compare them with Nvidia's last seven report-day moves and its 14-day average true range. Show every input.
Run it again on the morning of November 17, and once more on the 18th to see how the straddle's price compared with the actual move.
How to check what the assistant tells you
- Check the strike. The at-the-money strike is the one nearest the live price, not yesterday's close. Nvidia fell $11 in a day here; a straddle at $177.50 would be mostly a put that is already in the money, and its "expected move" would mean little.
- Check the time stamps. Bids and asks are live during market hours; outside them they go stale, and implied volatility computed from stale quotes can look strange.
- Check the open interest date. Open interest is a once-a-day figure, and the answer dates it. In this run it carried Friday, November 6, so the trading since then was not in it. Volume far above open interest, like the 170 call's 5,052 against 18, points to positions opened since that date.
- A straddle prices everything up to expiration, not only the report. That is why the before-and-after comparison in step 4 is more useful than either number alone.
- None of this is a forecast. Implied volatility is a price people are paying, and past moves are a small sample.
