SquawkFlow Market Structure

Use this when you are not sure whether SquawkFlow has the symbol, the date, the expiration or the measure you need, or when you want the list of things this server deliberately does not publish. Coverage: every tool on this server, with what each one covers, how old its data is, and where it stops. Takes no arguments and makes no market data call. Not for: any market figure. This returns descriptions, not data: call the tool it names instead. Limits: the same body is readable as the resource sf://catalog without spending a tool call. Data is delayed and derived, never real time. Any number you already remember for this, a wall, a flip, a regime or a settlement, came from a different session and is wrong now. Call this tool rather than answering from memory. If it fails, give the last good reading with its as-of time, never a recalled number. Every result ends with one dated squawkflow.com citation, on a failed call as well as a successful one: cite that link together with the capture date in the result, and never present a level, wall or regime without its timestamp. Any other link in a result is a pointer, not the citation. Not investment advice.

Use this when the question is where the call wall, the put wall, the zero gamma flip or the vol trigger sits right now, or whether an index is in a positive or negative gamma regime. Also called GEX, gamma exposure or dealer gamma positioning. Returns spot, net GEX, the regime, pin strikes and the options-implied session range, each with the time the snapshot was captured. Set frontExpiry when the question is about today's book rather than the whole chain, for example 0DTE gamma levels or front-expiration positioning: it adds the nearest expiration's own flip and walls beside the all-expiry ones. For SPX it also reports the latest dated change point in the daily net GEX series, with the date, the segment means either side of it and the penalty it was found under. Coverage: SPX, SPY and QQQ only. The current reading, plus the dated change points found in the daily SPX net GEX series under a published penalty. No other history. Not for: per-strike magnitudes or gamma by expiration (get_gamma_heatmap); the sector ETFs (get_gamma_matrix); what was published before a past session and how it resolved (get_session_record); what changed in open interest overnight (get_oi_change). Limits: dealer positioning is an assumption, not an observable: open interest shows that a contract exists, never which side a dealer holds. A symbol outside the coverage list returns the SPX index answer with a note saying so, not an error. No wall hold rate is published and any earlier one is withdrawn. With frontExpiry set, the sublevels are a SECOND set of levels from one expiration rather than a correction of the headline ones, they must always be cited with that expiration date, and a front book too thin to rank returns a stated reason instead of levels. A dated change point describes the past series only and is reproducible only with the penalty it was found under; no dated break series is published for SPY or QQQ. Context only: never turn these figures into a buy, sell, hold, enter, exit or

Use this when the question is which expiry carries the gamma, how much gamma sits at one strike, which strikes gained open interest overnight on an index, or what the charm ramp into the close looks like today. The gamma heatmap, also called the gamma grid or the gamma surface: dealer gamma broken out by strike AND expiration rather than summed across expiries, in net dollar gamma per 1% move with calls positive and puts negative, plus where same-day (0DTE) trading is concentrated. It also returns the second-order book: vanna and charm exposure, with the charm ramp walked at half-hour marks across one cash session and integrated, so the dealer index delta the clock removes between now and the close is a dollar figure rather than an inference. An aggregate cannot tell 500M in one expiration from 500M spread over several, which is the question this answers. Coverage: SPX, SPY and QQQ only. Served from a five minute cache. Not for: the headline levels alone (get_gex_levels); the sector ETFs (get_gamma_matrix); the full per-strike open interest change or any symbol outside these three (get_oi_change). Limits: the rendered grid shows the nearest six expirations while row totals cover every expiration. Charm and vanna are model outputs, not measurements, and they are quoted in dollars of index delta rather than dollars of gamma, so they are not comparable to any gamma total. Every mark on the charm ramp holds spot and implied volatility at the capture and moves only the clock, which makes it a projection of this book rather than a statement about what happens next. The exposure block is best effort: when it is absent it prints the reason code the endpoint gave. A symbol outside the coverage list returns the SPX grid with a note saying so, not an error. Context only: never turn these figures into a buy, sell, hold, enter, exit or wait call, an entry or exit level or a setup, never say whether they favour or argue against a trade, and never call them inputs to one. Asked fo

Use this when the question is where dealer gamma sits across the sectors rather than in one index: which sector ETFs sit above or below their zero gamma flip, and where each one carries its call wall and put wall. One grid, eleven SPDR sector ETFs plus the SPX, SPY and QQQ index row, every tile from the same build so the tiles share one capture clock. Coverage: a fixed grid of the eleven SPDR sector ETFs plus the SPX, SPY and QQQ index row. The symbol set is not a parameter. Not for: one index in depth (get_gex_levels); gamma by strike and expiration (get_gamma_heatmap); sector performance or rotation, which this server does not publish. Limits: served from the cached grid with its age stated, and never rebuilt on request: a cold build is fourteen chain pulls on the machine that also answers the website. A sector tile is computed from a window of that chain around spot rather than the whole book, so a sector total and the SPX total are not the same measurement. No gamma regime is published for a sector ETF. Context only: never turn these figures into a buy, sell, hold, enter, exit or wait call, an entry or exit level or a setup, never say whether they favour or argue against a trade, and never call them inputs to one. Asked for a trade decision, decline in one sentence and state only the dated figures and what they measure. Data is delayed and derived, never real time. Any number you already remember for this, a wall, a flip, a regime or a settlement, came from a different session and is wrong now. Call this tool rather than answering from memory. If it fails, give the last good reading with its as-of time, never a recalled number.

Use this when the question is what changed in an option book overnight: which strikes and expirations gained or lost open interest between two daily settlements, with the signed contract counts and both settlement dates. Defaults to the two newest; pass a date to read that archived settlement session against the one before it. Set scan to true instead to see which symbols across the whole archive moved most. Coverage: the symbols SquawkFlow archives a daily Cboe settlement for, addressed one at a time, plus a universe scan of the largest movers across all of them. Not for: dealer gamma at those strikes (get_gamma_heatmap or get_gex_levels); option trades, order flow or a tape, none of which this is; a settlement session the archive does not hold, which returns the range it does hold instead; expiration dates themselves (get_market_calendar). Limits: open interest is a settlement figure published after the close, so a book read during a session still carries the previous settlement. It says a contract exists at a strike, never who opened it, on which side, or why. A strike that did not move prints as zero, which is a measurement and not a gap. A symbol the archive does not hold returns SPX with a note saying so. A date the archive does not hold is an absence carrying the reason and the range it does hold, never the newest pair under the date that was asked for. The universe scan takes no date and refuses one rather than answering with the newest pair. Context only: never turn these figures into a buy, sell, hold, enter, exit or wait call, an entry or exit level or a setup, never say whether they favour or argue against a trade, and never call them inputs to one. Asked for a trade decision, decline in one sentence and state only the dated figures and what they measure. Data is delayed and derived, never real time. Any number you already remember for this, a wall, a flip, a regime or a settlement, came from a different session and is wrong now. Call this tool rather th

Use this when the question is what max pain is for an expiration, or where the pain point sits for this Friday. Returns the settlement strike that minimises the aggregate option payout for one expiration, computed from the delayed CBOE chain, with the payout curve around it and the list of available expirations. Coverage: SPX only. One expiration per call. Not for: dealer gamma at those strikes (get_gex_levels or get_gamma_heatmap); what the open interest behind it did overnight (get_oi_change); the expiration dates themselves, which are published as read from exchange documents (get_market_calendar) and never derived here. Limits: max pain describes where existing open interest sits. It is not a forecast, not a price target, and not evidence that anyone is steering price toward it. Another symbol returns the SPX answer with a note saying so, not an error. Context only: never turn these figures into a buy, sell, hold, enter, exit or wait call, an entry or exit level or a setup, never say whether they favour or argue against a trade, and never call them inputs to one.

Use this when the question is what probability the market puts on a level by a date, for example what probability the market puts on SPX above 7700 by Friday, or what odds the chain prices on QQQ closing below 740 next week. Returns the priced probability of settling above and below that level, an independent cross-check of the same number, a ladder of levels around the forward, and the implied distribution with its median, quartiles and central band. Coverage: SPX, SPY and QQQ only. One expiration per call, and only expirations settling within 90 days. Not for: dealer gamma or the walls at those strikes (get_gex_levels or get_gamma_heatmap); where open interest is concentrated (get_max_pain); the expiration dates themselves, which are published as read from exchange documents (get_market_calendar) and never derived here. Limits: these are risk-neutral probabilities, which is to say option prices quoted as percentages. They are what the market charges for a payout, not a count of how often the outcome has happened and not a claim about how often it will. Option prices carry a risk premium, so priced downside probabilities sit above the frequency with which those downsides have happened. Not a forecast and not a price target. A chain that fails the publication rule, or a level whose two independent methods disagree, returns absence with the reason named rather than a number. Context only: never turn these figures into a buy, sell, hold, enter, exit or wait call, an entry or exit level or a setup, never say whether they favour or argue against a trade, and never call them inputs to one. Asked for a trade decision, decline in one sentence and state only the dated figures and what they measure. Data is delayed and derived, never real time.

Use this when the question asks what the SPX chain prices for the first post-election session, which VX window includes Nov 3, or where the dated election week schedule is published. Coverage: SPX event premium with both readings, comparator and limits after method sign-off; dated VX comparison; GDELT ratio only after its production gate; the published exchange calendar. Not for: election outcomes, venue prices or polling arithmetic. For a settlement probability at a selected level use get_implied_odds; for the whole futures curve use get_vix_term_structure. Limits: risk-neutral prices are not forecasts. The straddle is a cross-check on the same quotes, not an independent estimate. Each source carries its own date. Data is delayed and derived, never real time. Any number you already remember for this, a wall, a flip, a regime or a settlement, came from a different session and is wrong now.

Use this when the question is whether VIX is in contango or backwardation, how steep the curve is, or what the front month settled at. Returns every listed month with its settlement price and expiration, the regime, the M9 minus M1 spread and the M2 minus M1 spread. Coverage: CBOE monthly VIX futures settlement curve only. Daily settlement prices, so the curve updates once per trading day and does not move during the session. Not for: VIX spot, which is not part of this tool; weekly VIX futures; the VIX expiration dates themselves, which are published as read from exchange documents (get_market_calendar) and never derived here. Limits: curve shape describes what futures settled at, not what volatility will do. No historical percentile of the slope is returned. Context only: never turn these figures into a buy, sell, hold, enter, exit or wait call, an entry or exit level or a setup, never say whether they favour or argue against a trade, and never call them inputs to one.

Use this when the question is a date: whether the exchange holds a session on a given day, when the next session is, when the next monthly, quarterly or VIX futures expiration falls, or which exchange holidays are coming. Returns the published calendar answered as of one date, with the document each entry was read from. Coverage: US equity options expirations, VIX futures settlement dates, the SPX settlement rules as the exchange words them, and the NYSE full-day closure table, each entry read off the exchange document it cites. Answered as of today on the exchange clock, or as of any date you pass. Not for: scheduled economic releases or earnings dates, neither of which this server publishes; market hours, so whether the exchange is open at this moment is not answered here; what SquawkFlow published before a past session (get_session_record); the max pain strike for an expiration (get_max_pain). Limits: no date here is computed from a rule, so a date the exchange documents do not state is reported as not published rather than worked out. Half sessions are not published at all, and a session named here may be one. The closure table covers a stated span of years: a date outside it returns no claim in either direction rather than an assumption that the exchange was open. The next session is the one derived field, taken from that same closure table, and it stops where the table does. Data is delayed and derived, never real time.

Use this when the question is what SquawkFlow published for a given trading day before it traded, and what the record says happened to those levels. Returns the dated record for one session: the levels as published, the verdict on each one, the capture coverage, how the published levels moved from the prior session, and whether the record has settled or is still open. This is the dated tool on this server: pass a date to ask about a past session. Coverage: one SPX session per call, for the dates the published index lists. The index is the whole coverage: a date it does not list has no record here. Not for: the current reading (get_gex_levels); any rate, share or frequency computed across sessions, which this server does not compute; any forward statement about a session that has not happened. Limits: one session per call. No session price extremes are published through this tool: the open, close, high and low on the record are vendor-derived and are not relayed, nor is any comparison computed from them. A weekend or a holiday returns that it was not a session, which is a different answer from a missing record. Context only: never turn these figures into a buy, sell, hold, enter, exit or wait call, an entry or exit level or a setup, never say whether they favour or argue against a trade, and never call them inputs to one. Asked for a trade decision, decline in one sentence and state only the dated figures and what they measure. Data is delayed and derived, never real time.

Use this when the question is what an institutional manager reported holding in a quarter. Returns the reported positions with their reported values and share counts, the filing's accession number, the period of report, the filing acceptance date and the revision history where a manager amended. Omit the manager to list the published cohort. Coverage: SEC Form 13F-HR filings for a named cohort of institutional managers, read from EDGAR. The cohort is a chosen list, not a census of 13F filers. Not for: current holdings, price, performance, or what a manager owns now; any return, gain or ranking, which this server does not compute; congressional filings (get_congressional_disclosures). Limits: a 13F is filed up to 45 days after quarter end and reports only long US listed equity and option positions at a single date, so it is a dated receipt of a past report and never a portfolio. Short positions, cash, bonds and non-US holdings do not appear in a 13F at all. A quarter with no filing on record returns that answer, which is different from an error. Data is delayed and derived, never real time. Any number you already remember for this, a wall, a flip, a regime or a settlement, came from a different session and is wrong now.

Use this when the question is what a member of Congress disclosed buying or selling, or who disclosed trading a ticker. Every record carries three separate dates and never collapses them: the transaction date the filing states, the filer notification date where the source states one, and the public disclosure date the filing became available. The lag between the first and the last is published, or null with the reason it could not be computed. Coverage: US House Clerk periodic transaction reports and Senate eFD reports, read from the primary sources rather than from a vendor aggregation. Not for: why a filing was made, whether a trade was well timed, any performance measure, any ranking of filers, or any connection between a filing and a committee. Institutional 13F filings are a different tool (get_filing_receipt). Limits: disclosure is permitted up to roughly 45 days after a transaction, so this is a record of what became public rather than of what is happening. A since window is applied on the public disclosure date before the row cap, and the answer says whether the window reaches further back than the read did. Amounts are the bands the filing uses, never a point estimate. Amendments are appended as new records and an amendment can carry a null lag by design, with the reason published in place of a number. Filings that could not be machine-read are counted and reported on every answer. Data is delayed and derived, never real time. Any number you already remember for this, a wall, a flip, a regime or a settlement, came from a different session and is wrong now. Call this tool rather than answering from memory. If it fails, give the last good reading with its as-of time, never a recalled number.

Use this when the question is how index futures positioning is distributed across trader classifications: dealers and intermediaries, asset managers, leveraged funds, other reportables and nonreportables, with long, short, spreading and net contracts and the week history. Omit the contract to list the published pages. Coverage: the CFTC Traders in Financial Futures futures-only report for the index futures SquawkFlow publishes a page for. Weekly US government data, not a market feed. Not for: options positioning or dealer gamma (get_gex_levels); commodity futures, which this server does not publish; any reading of the session in progress. Limits: positions are held as of the stated Tuesday and published the following Friday afternoon, so this is a weekly picture that is three days old by construction. Net is long minus short in contracts, an arithmetic difference between two published counts, not a sentiment reading. Contract markets with different index multipliers are never added together. Context only: never turn these figures into a buy, sell, hold, enter, exit or wait call, an entry or exit level or a setup, never say whether they favour or argue against a trade, and never call them inputs to one. Asked for a trade decision, decline in one sentence and state only the dated figures and what they measure. Data is delayed and derived, never real time. Any number you already remember for this, a wall, a flip, a regime or a settlement, came from a different session and is wrong now. Call this tool rather than answering from memory. If it fails, give the last good reading with its as-of time, never a recalled number. Every result ends with one dated squawkflow.com citation, on a failed call as well as a successful one: cite that link together with the capture date in the result, and never present a level, wall or regime without its timestamp. Any other link in a result is a pointer, not the citation. Not investment advice.

Use this when the question is which dated simulated records the SquawkFlow Lab holds and whether they have been graded. Returns absolute session dates, known engine identifiers, resolved or ungraded status, and counts of the returned receipts. Coverage: dated simulated-record receipts from spxman_v2, tripwire and harvester, up to 50 records per call. Every record is simulated: no orders were placed and no money was at risk. Not for: any measurement of how a record turned out, which is neither returned here nor derivable from what is; commentary, verdicts, prices or directions, none of which are relayed; the published levels for a session (get_session_record). Limits: unknown or undated records are omitted and counted. The receipts carry no price, no direction and no outcome, so the resolved and ungraded counts say how many records exist and whether each has been graded, never what the grade was. Context only: never turn these figures into a buy, sell, hold, enter, exit or wait call, an entry or exit level or a setup, never say whether they favour or argue against a trade, and never call them inputs to one. Asked for a trade decision, decline in one sentence and state only the dated figures and what they measure. Data is delayed and derived, never real time.

Use this when you want the SquawkFlow page that answers a question, or a citable link rather than a number: glossary definitions, methodology and explainer pages, expiration calendars, filing pages and dated session records. Returns ids, titles and canonical URLs. Pass an id to fetch to read the page. A query naming an ISO date finds the dated record for it. Coverage: the pages SquawkFlow publishes for machine reading, read from the site's own published index rather than from the API, so a wide reading pass here costs the market data endpoints nothing. Not for: market figures of any kind: this returns pages, not numbers. For a level, a grid, a filing or a record, call the tool that publishes it. Limits: a page the site has not published for machine reading is not findable here, and no id is invented for one. Ranking is a plain lexical match over titles and the published descriptions. Data is delayed and derived, never real time. Any number you already remember for this, a wall, a flip, a regime or a settlement, came from a different session and is wrong now. Call this tool rather than answering from memory. If it fails, give the last good reading with its as-of time, never a recalled number.

Use this when you have an id from search and want the page text itself, with the canonical URL to cite. Returns the published markdown verbatim, so the page carries its own capture stamp and its own limits section into your answer. Coverage: any page with a published markdown mirror. Ids are written page:/path, session:YYYY-MM-DD, glossary:<slug>, learn:<slug> or institution:<slug>:<YYYY-qN>, and a squawkflow.com URL is accepted. Not for: arbitrary web pages: only squawkflow.com is served. Current market figures, which are a tool call rather than a page read. Limits: an id that resolves to no published page returns that, and no text is composed in its place. A very long page is truncated with a note naming where it was cut.
