Check two separate NSE records: the Security in ban period for the next trade date – F&O segment file for a temporary open-interest ban, and NSE’s contract-information records to confirm whether the stock is an F&O underlying. A stock can remain eligible for listed derivatives while temporarily in the ban. The ban file is date-specific, so verify the session it covers before relying on a status.
What the two checks tell you
“Is this stock in the F&O ban?” and “Is this stock eligible for F&O contracts?” are different questions, answered by different NSE information. The first concerns a temporary trading restriction triggered by aggregate open interest relative to the stock’s market-wide position limit (MWPL). The second concerns whether NSE lists the stock as a derivatives underlying under its selection and review framework.

| Question | Where to check | What the record means |
|---|---|---|
| Is the stock in the ban for a particular session? | NSE Market Wide Position Limit page: “Security in ban period for the next trade date – F&O segment” | A daily, session-specific status tied to aggregate open interest and MWPL. NSE says securities in the file have crossed 95% of MWPL. |
| Is the stock an F&O underlying, and what contracts are listed? | NSE Contract Information page: “List of Underlying and Information,” contract specifications, and the “F&O Stock Introduction and Exclusion Tracker” | Underlying and contract information under NSE’s eligibility and review framework. This is separate from the daily ban file. |
Neither an old screenshot nor a broker watchlist establishes the status for an upcoming session. Use NSE’s current records and identify the relevant trade date.
The simplest way to avoid confusion is to keep the two answers side by side. The ban file answers a short-term, session-specific question about whether exposure has crossed a limit. The contract-information page answers whether NSE currently lists the stock as an underlying and provides information about its contracts. A “yes” to one question does not determine the answer to the other.
#1 Best Overall
| Ban file result | Underlying-list result | How to describe it |
|---|---|---|
| Stock appears for the session | Stock appears as an underlying | The stock is listed for the specified ban session and remains shown as an underlying; those are separate facts. |
| Stock does not appear for the session | Stock appears as an underlying | The stock is not shown in that session’s ban file, but remains listed as an underlying in the record checked. |
| Stock appears for the session | Stock does not appear as an underlying | Do not infer ongoing contract availability from the ban entry; check the tracker and current contract information for exclusion or contract-specific details. |
| Stock does not appear for the session | Stock does not appear as an underlying | The absence from the ban file is not evidence of F&O eligibility. Report the two findings separately. |
The table is a way to organize your check, not a substitute for the exchange records. In particular, the ban file’s absence of a symbol only answers whether it is listed in that file for its stated session. It does not certify that contracts are currently available.
How to check whether a stock is in the F&O ban
- Identify the stock precisely. Note the company name and NSE symbol. Confirm that you are checking the stock, rather than a similarly named security, index, or another exchange’s instrument.
- Identify the session you mean. NSE’s ban file is explicitly for the next trade date. Check the date shown with the file and the exchange trading calendar. A weekend or market holiday can make the next trade date differ from the next calendar day.
- Open NSE’s Market Wide Position Limit page. Find the file labelled “Security in ban period for the next trade date – F&O segment” and open or download it.
- Search the file for the exact symbol or company name. Check the file’s effective date as well as the matching entry. A match means the stock is listed for the session covered by that file; it does not establish its status for a later session.
- Record the date and time of your check. When sharing a status, state the session covered by the file and when you checked it. NSE’s reports catalog also lists security-in-ban-period and combined-open-interest reports, which can provide additional report context.
NSE describes securities in the next-trade-date ban file as having crossed 95% of their market-wide position limit. The file is the practical check for the upcoming session; a status reported without its effective date can be misleading because the contents can change each trading day.
When you search the file, treat the effective session as part of the result, not as a footnote. For example, a useful note says, “The symbol appears in NSE’s ban-period file for [specified trade date], checked [date and time].” If it is absent, say it was not listed in that file for the specified session. Avoid shortening either result to “banned today” unless you have confirmed that the file’s next trade date is the session you mean.

A report or screenshot detached from its date can be misread as a current status.
What the ban restricts—and what it does not
During the ban, clients and trading members may trade only to reduce positions through offsetting positions. Increasing open positions is restricted and can attract disciplinary action. This is not a blanket prohibition on trading or on closing or reducing an existing position: the relevant distinction is whether a trade offsets exposure or adds to it.
NSE Clearing explains that aggregate futures-and-options open interest across exchanges is compared with the stock’s MWPL. When that aggregate exceeds 95% of MWPL, the exchange takes note of end-of-day open positions; from the next day, trading is permitted only to reduce positions by offsetting. The restriction therefore follows a market-wide exposure measure, not just open interest on NSE or a single trader’s position.
This timing matters when explaining why a stock is in the file. The trigger is based on aggregate open interest exceeding the threshold, and the exchange takes note of end-of-day open positions. The reduction-only restriction applies from the next day. That is why the file is framed around the next trade date rather than as a generic, undated label. Use NSE’s file for the applicable session instead of trying to infer the restriction from an older reading of open interest.
NSE’s trading system provides an alert when NSE open interest exceeds 60% of MWPL. That is an early-warning level, not the ban trigger. Do not treat an alert at 60% as proof that the stock is already in the ban.

Keep the 60%, 95% and 80% figures distinct. The 60% figure is an NSE trading-system alert level. The 95% figure is the cross-exchange aggregate open-interest threshold associated with the ban. The 80% figure is the level at or below which normal trading resumes. They describe different points in the process, and the 60% warning should not be reported as though it were the ban threshold.
Normal trading resumes only after aggregate open interest across exchanges falls to 80% of MWPL or below. NSE Clearing states: “The normal trading in the scrip is resumed only after the aggregate open interest across Exchanges comes down to 80% or below of the market wide position limit.” The 80% resumption level is distinct from the 95% threshold that triggers the ban.
It is also important not to substitute a one-exchange figure for the relevant aggregate. NSE’s system alert refers to NSE open interest, while the ban trigger and resumption test described by NSE Clearing refer to aggregate open interest across exchanges. A single exchange’s open-interest figure or an individual participant’s position cannot establish that the market-wide threshold has been crossed or that it has fallen back to the resumption level.

- Open NSE’s Contract Information page. Use the “List of Underlying and Information” section to verify whether the stock appears as an underlying.
- Inspect the contract specifications. Check the listed contract information for the stock rather than inferring availability from a price chart, an old contract, or a broker’s search result.
- Check the “F&O Stock Introduction and Exclusion Tracker.” Use it to review introduction or exclusion information relevant to the stock and its current listing status.
- Keep the date in view. NSE’s list and tracker are the practical records for current underlying and contract information. The selection criteria are based on rolling market data, and the eligible list can change.
A broker may display instruments available to its customers, but a broker watchlist is not a substitute for checking the exchange’s current underlying information. Use the NSE records to establish exchange listing status.
Make the underlying check separately from the ban check, even if you have already found the stock in one NSE record. The list of underlying and information answers whether NSE currently shows the stock as an underlying; the contract specifications let you inspect the listed contract information; the introduction and exclusion tracker gives context on changes to the eligible stock list. Each record serves a different purpose.
If you are checking a particular contract rather than only underlying status, do not assume that seeing the stock name is enough. Inspect the contract specifications and available contract information for that stock. The source of truth for current listing information is NSE’s exchange record, not a remembered contract, a chart, or a saved broker search.
NSE’s published stock eligibility criteria
NSE’s selection criteria page describes thresholds for choosing stocks for equity derivatives. The criteria include rolling six-month data, so the figures explain the framework; they do not, by themselves, prove that a particular stock is currently listed or will remain listed.

Clear out junk files and repair common Windows errorsFree Scan →Scan for outdated or missing drivers - takes under a minuteDriver Scan →Repair Windows errors before they cause bigger problemsFix Now →| Criterion | Published requirement | How to interpret it |
|---|---|---|
| Market capitalisation and traded value | Among the top 500 stocks by average daily market capitalisation and traded value, using rolling six-month data | A ranking condition; it is not simply a fixed rupee cutoff. |
| Median quarter-sigma order size | At least ₹75 lakh | A separate liquidity-related selection threshold published by NSE. |
| Market-wide position limit | At least ₹1,500 crore | The stock must meet NSE’s stated MWPL criterion for selection. |
| Average daily cash-market deliverable value | At least ₹35 crore | A cash-market activity criterion in the selection framework. |
These thresholds are not a shortcut for deciding current eligibility. The criteria page explains the rules, while the underlying list and introduction/exclusion tracker show the practical current listing information. A stock meeting a threshold should not be called eligible unless the current exchange record supports that conclusion.
The top-500 condition uses average daily market capitalisation and traded value over rolling six-month market data. It is therefore a relative ranking requirement, not a claim that there is one fixed rupee market-capitalisation figure that automatically qualifies every stock. The other published thresholds are separate tests: the median quarter-sigma order size must be at least ₹75 lakh, MWPL at least ₹1,500 crore, and average daily cash-market deliverable value at least ₹35 crore.
Do not confuse the MWPL selection minimum of ₹1,500 crore with the ban calculation. The selection page sets a minimum MWPL as one condition for stocks chosen for equity derivatives. The ban process compares aggregate open interest with the stock’s MWPL and uses 95% as the trigger and 80% or below as the resumption level. One is an eligibility criterion; the other is a position-limit rule applied to exposure.
Likewise, the thresholds explain NSE’s selection framework, but a reader generally cannot establish a live listing by calculating one criterion in isolation. The criteria use rolling data and are considered as a set. To answer whether a stock is currently listed, check NSE’s underlying list and introduction/exclusion tracker. To explain why selection is governed by liquidity and market-size measures, quote the published criteria with their units and keep them clearly separate from the status result.
How removal from F&O works
A daily ban is not removal from the derivatives segment. The ban is an exposure-based restriction for a specified session; removal is governed by a separate eligibility review.
NSE says that failure to meet any listed selection criterion for three continuous months can result in exit, subject to its framework and a minimum of six months since the stock’s introduction. If a stock is excluded, existing unexpired contracts may be permitted to trade until expiry, while no fresh month contract is issued. The status of an individual contract therefore may not change at the same moment as the underlying’s eligibility status.
The three-month failure condition is about meeting the published selection criteria over time, not about appearing in the daily ban file. A stock may enter a ban because aggregate open interest is high without thereby failing the eligibility tests. Conversely, a review of eligibility can lead to exclusion under the separate framework; being absent from a particular day’s ban file does not rule out an exclusion or establish continued listing.
The six-month minimum since introduction is also a distinct part of the exit framework. It should not be confused with the three continuous months of failing any listed criterion. NSE’s page says failure for three continuous months can result in exit, subject to that minimum period since introduction and the applicable framework. Avoid describing exclusion as an automatic consequence of one day’s figures or one ban event.

1Fix the driver behind crashes, sound loss and screen glitches2Clear out junk files and repair common Windows errors3Scan for outdated or missing drivers - takes under a minuteIf a stock is excluded, existing unexpired contracts may be permitted to trade until expiry, while no fresh month contract is issued. This means the underlying’s status and the lifecycle of contracts already listed are not necessarily identical. If the practical question is whether a particular contract is available, check the current contract information instead of assuming that an existing unexpired contract means new contracts will continue to be issued.
NSE further states that an excluded stock is not considered for re-inclusion for one year. After that period, it must meet the criteria for six consecutive months before it can be reintroduced, subject to SEBI approval. Check the tracker and current contract information rather than assuming that a prior inclusion continues or that an exclusion automatically reverses after a fixed interval.
The one-year exclusion period and the six consecutive months of meeting criteria describe steps in possible re-inclusion; they are not a guarantee of re-entry on a particular date. NSE’s stated condition also includes SEBI approval. For a status report, rely on the current list and tracker rather than predicting an outcome from elapsed time alone.
Common mistakes when checking status
- Using a file for the wrong session: “Next trade date” is not necessarily tomorrow on the calendar. Confirm the effective session.
- Conflating ban and eligibility: A stock in the ban can still be an F&O underlying; a daily ban entry is not an exclusion notice.
- Calling the 60% alert a ban: The alert is an early warning. NSE Clearing’s ban trigger is aggregate open interest across exchanges exceeding 95% of MWPL.
- Assuming all trades are forbidden during a ban: The stated restriction permits offsetting trades that reduce positions; adding open positions is restricted.
- Relying on an old image or undated list: The daily ban file changes and addresses a particular upcoming trade date.
- Using eligibility thresholds as a live status list: Rolling criteria explain selection and review, but current listing must be checked on NSE’s underlying and tracker records.
- Checking only one exchange’s open interest: The trigger and resumption test refer to aggregate open interest across exchanges, not NSE open interest alone.
Another common reporting error is to describe the whole stock as “banned” without saying what that means. The relevant NSE file names securities in a ban period for a specific next trade date, and the restriction is on increasing open positions: permitted trades are those that reduce positions through offsetting. State the affected session and the nature of the restriction rather than implying that all activity, including closing or reducing a position, is prohibited.

Similarly, avoid treating an eligibility threshold as proof of a current contract. The ₹75 lakh, ₹1,500 crore and ₹35 crore requirements, as well as the top-500 rolling ranking, describe published criteria. They do not replace NSE’s current underlying list, contract specifications or tracker. A stock can pass a threshold but still require a current-list check; a broker’s displayed availability is not the exchange’s official underlying record.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.A reliable way to report the result
For a clear, verifiable status note, include the exact stock name or symbol, the session covered by the ban file, the time and date you checked it, and the separate result from NSE’s contract-information records. For example, state that the stock appears—or does not appear—in the file for the specified next trade date, then separately state whether the current underlying information lists it. Do not collapse those observations into a single claim that a stock is simply “banned” or “eligible.”
A concise status note can follow this pattern: “For [trade date], [company/symbol] [appears/does not appear] in NSE’s next-trade-date F&O ban file, checked [date and time]. NSE’s contract-information records [list/do not list] the stock as an underlying in the records checked.” This format makes the session and the two independent findings visible. It also avoids suggesting that one record answers both questions.
If the underlying record or tracker indicates an exclusion, describe that separately from the ban-file result. If unexpired contracts remain, the criteria page says they may be permitted to trade until expiry while no fresh month contract is issued. Check the contract information before making a claim about a particular contract; do not infer its status from the daily ban file or from the stock’s general history of being listed.
NSE’s reports catalog can also be useful when a dated report is needed: it separately lists security-in-ban-period and combined-open-interest reports. These reports complement the status check; the next-trade-date file remains the direct reference for whether the stock is listed in the ban for that session.
Best Value
For a reusable checking routine, capture four items: the exact symbol, the next trade date shown on the file, the ban-file result, and the underlying-list or tracker result with the date checked. If you are explaining the rules, add the relevant distinction rather than overloading the status: 95% is the ban trigger, 80% or below is the resumption condition, and the criteria page’s thresholds govern selection and review. This keeps a brief update both useful and verifiable.
Frequently Asked Questions
How do I check if a stock is in the NSE F&O ban today?
Open NSE’s Market Wide Position Limit page and check the “Security in ban period for the next trade date – F&O segment” file. Confirm the effective trade date, then search for the exact NSE symbol or company name. The file covers the next trade date, which may not be the next calendar day if there is a weekend or market holiday.
Does an F&O ban mean the stock has been removed from derivatives?
No. The daily ban is a temporary restriction tied to aggregate open interest and MWPL. Removal from F&O follows a separate eligibility review. Check NSE’s “List of Underlying and Information” and “F&O Stock Introduction and Exclusion Tracker” to verify current underlying information.

What happens to trading when a stock is in the ban period?
Clients and trading members may trade only to reduce positions through offsetting positions. Increasing open positions is restricted and can attract disciplinary action. The restriction is not a blanket ban on closing or reducing an existing position.
What are the 95% and 80% MWPL levels?
NSE Clearing says the ban trigger is aggregate futures-and-options open interest across exchanges exceeding 95% of MWPL. Normal trading resumes only when aggregate open interest across exchanges falls to 80% of MWPL or below. NSE’s 60% open-interest alert is an early warning, not the ban trigger.
What are NSE’s published stock eligibility thresholds for F&O?
NSE’s criteria include a top-500 ranking by average daily market capitalisation and traded value using rolling six-month data, median quarter-sigma order size of at least ₹75 lakh, MWPL of at least ₹1,500 crore, and average daily cash-market deliverable value of at least ₹35 crore. Check the current underlying list and tracker for actual listing status.
Can an excluded stock still have F&O contracts?
NSE says existing unexpired contracts may be permitted to trade until expiry after exclusion, while no fresh month contract is issued. Check NSE’s current contract information for the status of a specific contract. Re-inclusion is not automatic: NSE states that an excluded stock is not considered for one year and must meet criteria for six consecutive months before reintroduction, subject to SEBI approval.
The Bottom Line
Use NSE’s next-trade-date ban file to answer whether a stock is in the temporary MWPL ban for a specific session, then check the Contract Information page and introduction/exclusion tracker separately to establish underlying status. Keep the dates attached to both findings: the ban is triggered above 95% of aggregate cross-exchange open interest and normal trading resumes at 80% or below, while F&O eligibility follows a separate rolling selection and review framework.
