CBOE

Regular-Hotel892

Even with the instituional level / most expensive granular data from the exchange “dealer positioning” in aggregate across SPX 0dte strikes for example is impossible to compute. The dataset simply does not exist. The CBOE Open-Close summary does not tell you what people seem to think it does

CBOE data. For SPX

duboilburner

CBOE sells the data for SPX and VIX at least. The companies that do the best to show the data accurately are Unusual Whales' Periscope, OptionsDepth and new guys VS3D (VS=VolSignals). I currently pay for UW's Periscope. I also am in VolSignals' discord to learn how a former market maker understands the data, how they have to hedge with buying or selling futures through different exposures. OptionsDepth and VS3D offer a neat visualization/gradient map of sorts that also predicts what charm and gamma are likely to be as decay happens throughout the day. UW Periscope does not.

crazybitcoinlunatic

Where do you get this data? CBOE?

heroyi

No services provide real time because you cannot adjust the positioning on real time. No, flow data is inaccurate just as well since the market most likely moved away from what the midpoint of the spread may suggest which is why ddoi isn't suitable UNLESS you are ok with that noise and want something for in between. Also, Spotgamma and VS3D definitely differentiate long/short at least for SPX. Equity is a different story because it is absurdedly expensive to not only buy all the reports but some of the exchanges may not even offer a proper tagging like CBOE does.

MrDerivatix

Hey OP. I’m unaware of your context but Bloomberg’s tick-by-tick is probably an overkill (and expensive) for most 0DTE setups unless you’re running a legit HFT desk. PapaCharlie9 gave you useful alternative, but in case you prefer to outsource this problem, you can check out ORATS. They have a live data API that runs with <10 seconds of market delay, which for 0DTE mm is more than fast enough unless you’re competing with Citadel’s colos. Just beware, is not “cheap”. Pricing-wise, the intraday recurring data is around $199/mo. Not cheap, not Bloomberg-expensive. For me the data quality on the IV surface is genuinely better than what you’ll get from most retail-facing providers because they’re fitting a parameterized curve (slope + derivative) rather than just spitting out raw mid-market IVs. For the real pros that need sub-second updates you’re probably looking at OPRA feed direct or through a vendor like LiveVol/CBOE DataShop. What’s your actual latency requirement? That’ll narrow it down fast.

duboilburner

I don't have a link, I just know Daniel Roos (former head of SPX options trading at Belvedere), aka VolSignals has mentioned it repeatedly, as he's built a platform to disseminate the data and he's more plugged into where to get it from and what is upcoming based on what they tell him. Keeps referring to the upcoming shift to also have 1 minute updates instead of only 10 minute, and keeps calling it a "firehose of data." So, he's been gearing up to make sure his servers are going to be able to handle the much more frequent calculation of positions and how to display it, as I think it is a good bit of computing power that's now about to go up by a factor of 10... I don't know if they will have different tiers where you can pay less and still get the traditional every 10 minute updates, and pay more if you want the whole 'firehose' every minute or how it's going to work. I don't think that the raw data from CBOE is as useful to us as it is through these other platforms that turn it into graphs and gradient maps.

CBOE releasing gex 1 minute streams? Can you provide a link to more?

duboilburner

Unusual Whales' Periscope for SPX options, updates every 10 minutes, has the real positioning info instead of naive GEX based on OI. If you want some extra info and fancy visuals to go with it, OptionsDepth. There's also a new player on the scene that's been put together by a professional ex floor trader, basically trying to recreate the data and toolsets he had when he was a market maker. It's called VS3D, VS standing for VolSignals. I pay to be in his 'pro' discord to pick up some of his professional opinions on how he is translating the data to help my learning process, but I'm not paying for VS3D yet. Unusual Whales Periscope gets me 90% of the way there, just doesn't have the extra fancy visuals, which can be helpful. CBOE will be releasing 1 minute updated data streams soon... They are currently the ones who hold it to every 10 minutes for updates. All of the above mentioned services pay CBOE for the data, and then they parse and display it their own way. So, I suppose you could just pay CBOE directly, but I'm fairly certain that far exceeds what the other services charge. The other guys can charge less because they have numerous customers that can defray that cost... and the raw data may not be as useful as the already calculated displays UW, OD and VS3D offer.

According_Witness441

For infrequent use, free end-of-day data is usually enough. CBOE publishes basic historical options settlement data at no cost, and Yahoo Finance lets you manually pull past option chains by expiration and strike. Nasdaq Data Link (formerly Quandl) also has some free or very low-cost EOD datasets. The expensive platforms are mainly for continuous, cleaned data, so for occasional LEAP analysis, mixing these free sources is often the most practical approach.

You can sell naked puts on margin CBOE says for broad based index options: “100% of option proceeds plus 15% of underlying index value less out-of-the- money amount, if any, to a minimum for calls of option proceeds plus 10% of the underlying index value, and a minimum for puts of option proceeds plus 10% of the put’s exercise price.”

This was my response to another poster a couple of days ago and still same in terms of broad baskets: Selected tech (Japanese suppliers, memory, optics, semicap/semis) but that's even run so quickly opportunities have largely run dry. Have started trimming some memory exposure, which I won't time right but has gotten absurd. If I'm not buying anymore at this point and I don't see it as a long-term holding, I'm very, very gradually trimming. Defense (largely in other countries) AI power (turbine names, BE, etc) Hard assets, some US listed names but a lot in various other countries and via ETFs. Copper miners, uranium miners, aluminum, metal recyclers, gold miners, royalty plays, oil/gas + pipelines, etc etc etc. A lot of this stuff has already run a lot YTD. Commodity futures ETFs would also go in this basket. Biotech. I continue to enjoy dabbling in biotech and have done well with it, although keep it to a reasonable allocation. Financial markets names. (CBOE, etc.) Other odds/ends that don't fit in the baskets above (not as much here as there sometimes is; SATS for example is one.)

I don’t trade 0dte so I might not be the best judge. The CBOE apparently feels they can profit from additional and regular expirations, and the SEC has approved the expansion. Time will tell. But I expect more new traders will tap out early because they played casino instead of learning options trading.

JJdante

I was watching a tasty trade interview with a person working at the CBOE, and he said that retail is responsible for something like 60-70% of the volume on 0dtes. And the CBOE makes a lot of money on that volume- this feels like the natural evolution of that. My numbers might be off because it was awhile ago I saw the interview.

trebuchetguy

I'm going to be the weirdo who's serious for a moment instead of piling on. Let me share something a retired professional CBOE floor trader once told me. The market is a bunch of numbers. Stock, option, and futures prices, greeks, IVs, and so on. The rules of market engagement allow traders to pick and choose what opportunities to select, hold, and manage and which ones to walk away from. Here's what the market is not. It isn't a "supernatural" force or entity. It doesn't care about you or anyone. It is utterly indifferent. The moment one attributes their own failures to outside forces working against them, they have abdicated responsibility for their own success or failure. Honestly, that's easier because that makes it okay to be lazy because the "market is going to turn against me anyway." Trading with long term success is HARD. It requires study, understanding, preparation hours away from the screen where you aren't trading. That can be a real drag, but you have to do it. It requires failure and learning from failure and being utterly ruthless in self evaluation. That doesn't mean self flagellation, but quite the opposite. It means ruthlessly picking apart how one makes decisions, which ones worked and why and which ones didn't and why. Being able to differentiate a "bad break" from a "bad decision" is an absolute requirement.

PapaCharlie9

What exactly are you looking for? Why does it have to be "past"? The link below is all of the *presently* trading options on the CBOE. It's a ginormous CSV text file that just has the ticker and specs of every contract trading, but not just American style. It's easy to determine if an option is American or not just by process of elimination, since the list of European style options is quite short. SPX, XSP, NDX, RUT and a handful of others I'm sure you can research and discover for yourself, because I'm not going to write your paper for you. http://markets.cboe.com/us/options/market_statistics/symbol_reference/?mkt=cone&listed=1&unit=1&closing=1

Gold and bonds are traditionally considered hedges for some situations. If you want to hedge with stocks then: CME, CBOE, FICO are the ones that could possibly offer protection in a crash or major downturn. BRK - I consider defensive but not a hedge. There is no single hedge that can protect in all situations.

If you are going to submit this paper for publication eventually, you should try contacting the CBOE directly. They will let you gain access to past information for academic research.

Years ago: HistoricalOptionsData, ORATS, CBOE, Nanex. Now there should be many more. They all provide the same bid/ask data, so no real difference there, though each one mishandles some aspects of the data differently, especially in terms of non-standard options post-split and post-corp actions. I also had to spend months improving my own data cleaning/smoothing algos to revalue options based on bid/ask, as no one else can estimate their fair values properly.

Mental-At-ThirtyFive

I like iron condors. I do "conceptually" agree on martingales although "instinctively feel" (that's my risk profile) there has to be a "stopping rule / take my loss" to keep me in the game. A few questions. Do card players have an opinion on this (I understand blackjack has max bets that takes away martingale effectiveness, and poker is not susceptible to martingale)? Did the brokers let them run this strategy rampantly? Or maybe my ask is how do brokers' risk management handle this? Do exchanges (CBOE here) monitor these? Across multiple brokers? Anyway - big win for mtm for the risk transfers but how does it work for intraday risk management for the brokers and at the exchanges. Thanks to morningstar for the details. Well done Captain Condor for the trifecta - IC + 0DTE + martingales even if it blew up. A last comment after reading the article - having more intrday orders / activity more than JPM is not a good thing unless you are a big boy and play with their rules book

NY_State-a-Mind

You can buy SPX options for like 20 bucks. Also XSP is just like SPX and operated by CBOE as well but 10x cheaper

Thanks for the response. Do you think 1 minute data is necessary or is EOD enough for your level of success? Also, Is it worth paying extra to CBOE for data quality relative to other vendors?

deustrader

Initially I searched on Google and found HistoricalOptionsData (name of website). Later I also bought historical data from CBOE, probably cheaper a few years ago than now. At one point I also got data from Nanex - another provider. Now there are more that you can likely find on Google. Generally they all provide the same data in terms of bid/ask for each contract in 1-min intervals.

AnteaterFantastic212

I've been trading for about 15 years. I was fortunate enough to train with Dan Keegan, a former CBOE market maker who was on the faculty at the Chicago School of Trading at the time, which was very helpful in learning to manage risk like a market maker. He is still active and I would be happy to introduce anyone interested. A little education can save a lot of $ and heartache.

CBOE has created a silver volatility index, in case you are interested: [https://finance.yahoo.com/quote/%5EVXSLV/](https://finance.yahoo.com/quote/%5EVXSLV/) CME has one for futures, but you need a CME account to see it.

AnteaterFantastic212

The way to avoid such traumas is to learn how to manage risk properly and adjust positions in response to market dynamics. Reply if you would like a referral to a former CBOE market maker who can teach you to trade like a pro.

Got_Engineers

The only thing that could stop silver is if the CBOE increases margin rates on silver options/futures. I think they were called the Hunt Brothers or some shit but they were the dudes that had the monopoly on silver back in the day until they didn’t because the markets eventually took control. I know J.P. Morgan owns a shit ton of physical silver so someone must be the option writer on all of this. The fact that silver went up like 8% today when the SPY IV% was like 4% is kind of crazy.

TradingInsecurities

The VIX is a functionally meaningless vehicle that does nothing but earn fees for the CBOE. You would have better odds at a slot machine. It is the derivative of a derivative of a derivative. Here’s the uncomfortable truth: the VIX is the result of a formula that uses the midpoints of bid-ask spreads from a select group of out-of-the-money SPX options—on an index (the S&P 500) that is itself an index, of a selection of stocks, chosen by a committee, based on a 1950s understanding of “representative”. The VIX is an index of options on futures contracts on an index of options prices on a cherry-picked index of stocks. That alone should make you pause. But even worse is how this “fear index” is interpreted. In theory, the VIX should capture expected volatility—that is, standard deviation of returns in either direction. But in practice, it behaves asymmetrically. It spikes when the market drops, and it decays when the market rises. In other words, it’s mostly just a function of downside panic, not symmetrical uncertainty. The CBOE claims the VIX is “mean-reverting,” unlike the S&P 500, which “can rise indefinitely.” But this misuses the statistical concept. A truly mean-reverting process is one that oscillates around a central tendency. The VIX doesn’t do that—it just returns to a policy-influenced range (often around 12-15), largely because volatility expectations are anchored by central bank behavior, market maker liquidity, and structural hedging flows. That’s not mean reversion. That’s seasonal normalization in disguise. And here’s the real kicker: the options selected in the VIX calculation can shift depending on bid/ask spreads. If a nearby strike has no valid bid, it can be excluded entirely from the calculation—even if an adjacent strike is active. This can distort the entire volatility estimate, especially in low-liquidity environments like weekly expirations. So when you say the VIX is at 52w low what does that actually mean? Is it because there is low liquidity on SP 500 Index Options? Who knows?

RiskFirstExplains

This is normal and there’s no lack of transparency or broker funny business here. When you sell options, you’re assigned based on random assignment through the OCC, not based on who bought your specific contract. Each brokerage submits exercised contracts to the OCC, and the OCC randomly assigns those exercises to short positions within that brokerage only. That’s the key point. Because these were held at two different brokerages, the assignment pools are completely separate. One brokerage happened to receive an assignment, the other didn’t — even though the options are identical. A few clarifications: You will never know the identity of the counterparty. That information is not available to brokers, CBOE, or retail traders. The broker did not decide to exercise anything. The long holder exercised, the OCC processed it, and your account was randomly assigned. Being assigned on one account and not the other is very common when positions are split across brokers. If you’re short options and don’t want assignment risk, you need to close or roll before expiration, or manage margin so assignment doesn’t force liquidation. Nothing was taken from you and nothing was exercised “against” you unfairly — this is exactly how listed options are designed to work.

RiskFirstExplains

People are mixing up SPX vs SPY. SPX options can trade nearly 24h via CBOE Global Trading Hours, and some brokers allow premarket/overnight fills. SPY options cannot. SPY is an ETF and its options only trade during regular market hours (9:30–4:00 ET). If this was SPY, it didn’t actually execute premarket — the early timestamp is likely from the opening auction or how the broker reports the fill. The order was queued overnight and filled at the open. Also, market orders on options at the open are risky because spreads are very wide.

FleetAdmiralFader

There is transparency.  When an option is assigned the OCC randomly choose a broker that must then choose a position (via the broker's assignment rules) to assign. Your brokerage account is with someone that offers options through the CBOE. The CBOE is the broker of the option and assignment comes from them after they are chosen by the OCC. Thats why you are being told to ask the CBOE, but my guess is their assignment is also random. No company is going to tell you how it's random number generator works.

Ken385

The CBOE is one of 18 different options exchanges. The option assignment process is handled by the OCC (Options Clearing Corporation)

FleetAdmiralFader

Assignment is random and done by the CBOE. Someone chose to exercise [early] and you got unlucky

Not overfitting, but *structural change* as others here noted: * **2018 (The Reset):** "Volmageddon" (Feb '18) blew up the short-vol trade. Markets have priced tail risk and skew differently ever since * **2022 (The Shift):** CBOE added Tue / Thu expirations. Before this, you didn't have daily gamma exposure. Now, intraday moves are heavily driven by dealer hedging / gamma flows Don’t trust 0DTE backtests before mid-2022. Liquidity and flows driving today's strategies didn’t exist back then.

Welcome to options. When I took the traveling circus from the CBOE about trading options. I was a broker.

**on Tuesday, December 16, 2025**, the **VIX (CBOE Volatility Index)** chart is signaling a sharp increase in market anxiety. Often called the "Fear Gauge," the VIX is currently in a clear **intraday uptrend**. The VIX opened higher today at **17.28** (vs. yesterday's close of 16.50), reflecting immediate concern over the delayed jobs data. While it retreated slightly from its morning highs of **17.61**, it remains well above yesterday's levels. * **Inverse Correlation:** The upward move in the VIX chart is a direct mirror of the "Downtrend" status seen in the major indices (S&P 500, NASDAQ, and DJIA). As stocks have sold off due to weak economic data, the demand for portfolio protection (hedging) has driven the VIX higher. * **Resistance Levels:** The chart is currently testing resistance in the **17.50** zone. A sustained break above this could signal further downside for equities as we head into the market close. * **Short-Term Momentum:** Technical indicators like the **MACD** and **Stochastics** are showing "Buy" signals for volatility, suggesting that the momentum currently favors further spikes rather than a return to the "calm" sub-15 levels seen earlier this month.

Here is a detailed comparison of the December 5, 2025 DJIA **FEARLESS Forecast** versus the actual close, including intraday volatility and regime probabilities: * The forecast, **with the mean reversion filter added (see comments),** predicted a moderately bullish day with an expected return of about +0.30% and a directional bias of roughly 65% chance of an Up day. * The actual DJIA close on December 5, 2025 was 47,954.99, confirming a positive gain consistent with the forecast. * Intraday volatility on December 5, 2025 was moderate, with the CBOE DJIA Volatility Index (VXD) around 16–17, indicating a typical level of market uncertainty—not elevated or subdued. * Regime inference for that day showed a dominant Bull regime probability (\~70%), with smaller contributions from Range and Bear regimes, supporting the momentum-driven forecast. * No significant mean-reversion overlay event was active, so the model tilted toward continuation rather than reversal. * The actual close showed the model’s probabilistic range was well calibrated. Overall, the model’s forecast for December 5, 2025 aligned well with market behavior, capturing both the directional move and volatility environment accurately.

Michigan-Magic

Good answer on why VIX ETFs are not an investment. There are public entities that have a highly significant portion of revenue derived from market making activity (Flow Traders in Europe or Virtu in the US), as their market making revenue is tied to increased volume that should result from increased market volatility. Or can buy shares in an options exchange like the CBOE, whose volume in theory will ramp up due to volatility.

Mountain_Fig_9253

When there is a split or reverse split it takes a little bit for the CBOE to update the options to reflect how the share change affects the option. In a reverse split the options will change to be less shares. They make sure to keep it “fair” but the biggest issue is the liquidity dries up as no one wants to buy an OTM non-standard option. If it goes ITM don’t expect any extrinsic value. I’ve always gotten screwed with splits or reverse splits. It’s essentially the ultimate IV crush.

i4ismail

CBOE is charging exorbitant fees ... CBOE should reduce its fees ... esp for multi-leg orders also in this age of internet and digital, why should somebody charge per contract ? they should only be charging per ORDER ... the digital infrastructure is almost the same to execute 10 contracts in the order or 1 contract in the order ... brokers in countries like India only charge per order ... does not matter how many qty you put in your order

PapaCharlie9

PMCC is a type of diagonal. Diagonals are not regulated as spread structures for the most part, but rather as two individual trades. For example, the [CBOE strategy-based margin manual](https://cdn.cboe.com/resources/membership/Margin_Manual.pdf) doesn't include entries for PMCCs. If there are no special rules for that structure, the rules for the individual standalone legs are used instead. So in one sense, your broker doesn't need to know. All they have to do is make sure that the trades for each individual leg comply with regulations and internal business rules. This is why most brokers require that you have the option approval level for naked short calls in order to trade PMCCs. > Let’s say I own 5 LEAPS but I only want to sell 2 or 3 covered calls, which of the LEAPS get aligned to the short calls as collateral? Technically, none. Each is treated as a naked short call, which requires total account buying power for initial and maintenance margin. > And how would one calculate break even on the short call strikes when there’s a mix of LEAPS with different entry prices / BE? That's entirely up to you, since BE is an arbitrary number that only you would care about. Similar to what your target profit/loss percentages might be on the trade. > A few weeks ago I went long 4 SOFI LEAPS Calls and started selling covered calls against them, and I absolutely love it. Caution. You are NOT trading covered calls. Covered calls have a regulated definition that FINRA, SEC, and IRS care about. If you told an IRS auditor that you traded "covered calls" when they are in fact trading option diagonals, at best you will cause confusion, at worse you'll get into trouble.

Market makers are literally making quite a bit of money on 0DTE options, as there is a shit ton of volume there. The CBOE is also making shit loads of money there, too. That’s why they created them in the first place. So it’s not an opinion, you’re right. It’s a fact. And the correct answer to OPs question. Others might be making money too, but market makers are DEFINITELY making money.

Don’t know why you felt the need to downvote me. SPX options on CBOE. The GTH are 8:15pm - 9:25am. But they are currently not quoting as a knock on effect of the CME outage. Not surprising, since any market quoting SPX overnight is pricing off of the /ES price.

Spx options on CME? They are on CBOE no?

Getting CBOE adds while it's down is my personal peak today. "life is better with options, so could your trading strategy"

*one told me it is a daily average over a quarter not a single month* This is incorrect and suggests that the rep may be wrong about other things as well. It is the daily average over a month, not a quarter. If you go over this, you will be considered a pro customer for the following quarter. Some brokers may have stricter rules, but this is the way the exchange rules are written. From the CBOE rule, *the term “Professional” means any person or entity that (i) is not a broker or dealer in securities, and (ii) places more than 390 orders in listed options per day on average during a calendar month for its own beneficial account(s)* [RG16-064 Professional Orders](https://cdn.cboe.com/resources/regulation/circulars/regulatory/RG16-064.pdf)

It finished the contract at 18.11. It’s an am settlement. CBOE makes it damn tricky to find the settlements, but I had a long put 21 exp this morning, so I was eager to see how it would finish, and saw it this morning.

Ken385

You still don't seem to understand. The VIX settlement this morning was 18.11 Your 18 puts expiring this morning are worthless, they expired out of the money based on this settlement price. Again, here is the link from the CBOE that has the VRO settlement, [Weeklys Settlement Values](https://www.cboe.com/index_settlement_values/weeklys_settlement_values/) || || |VIX Option|VIX|2025-11-26|VRO|18.11|

Ken385

No, the settlement was based on this mornings opening price of specific SPX options one month from now. The VIX settlement is based on where these options open. The CBOE will post this calculation shortly after the opening at the link I posted above, which they did. 18.11 was the settlement price. You're right you can't now trade these options, but it takes time for your broker to remove them from your position.

When this shit eventually gives me heart problems I’m sueing the CBOE for damages

thank CBOE for inventing leaps
