Row sources: NSE—nse-page and nse-fields; Sensibull—sensibull and sensi-help; public Opstra—opstra; Quantsapp—quants; Dhan—dhan-web, dhan-free and dhan-oi; Kite—kite. Free feature access does not mean brokerage, exchange charges or taxes on trading are zero. OI means open interest; IV means implied volatility; LTP means last traded price; PCR means put-call ratio; ATM means at the money. Individual field lists are limited to what each source names.

Read the free chain before paying for more analysis

NSE's published chain configuration lists call and put open interest, change in open interest, volume, implied volatility, last traded price, price change and the best bid/ask with quantities, around a strike column. The page also offers symbol and expiry selection and a CSV download control. That is a useful exchange reference for the displayed contract fields. It does not make the page an order terminal or a guaranteed continuously fresh feed.

Sensibull's own comparison describes its basic chain with per-strike prices, open interest, Greeks and implied volatility. Its advanced chain adds put-call ratio, change in IV, intrinsic and time value, and a probability-of-profit field. Those are additional analytics, not proof that a displayed probability will predict a trade's realised result. The basic-versus-advanced distinction is more useful than treating every Sensibull screenshot as one universal free product.

Public Opstra documents an option chain with Greeks on both tiers, with different update descriptions. Quantsapp marks its chain-at-a-glance facility as free and offers paid what-if analysis. Its strategy Architect includes Greeks in the free tier, but that separate feature does not establish that every Greek is displayed directly in the free chain. We leave that exact field question open.

Dhan's product page documents an advanced chain with Greeks and direct trading. Kite's help describes a Greeks view for gamma, vega, theta and delta, plus chain summaries including put-call ratio (PCR), max pain, at-the-money IV and IV percentile. These product facts establish available analysis routes, without establishing which screen is easiest to use on a particular phone. For the terminology itself, use what an option chain shows; this page compares access to those fields.

A field comparison that avoids false matches

• Match the contract identity first

  Write the exchange, underlying, expiry, strike and call/put side beside any comparison. A nearby strike or different expiry is not a matching observation, even when the displayed price looks similar.

• Separate quotes from calculated fields

  Record bid, ask and last traded price separately from IV, Greeks and derived summaries. Dhan explains that models, inputs and update frequency can make IV values differ between platforms.

• Read the unit beside open interest

  Zerodha says exchange websites display OI in lots while Kite displays total quantity. Convert with the matching contract lot size before calling the numbers inconsistent.

• Keep the tier visible

  Record free or paid access and the actual account context. A broker-funded entitlement and a general free plan can expose different features under the same brand.

• Treat a blank as a question

  Check selection, filters, display range and loading state before alleging a missing contract. This guide contains no observed missing-strike count and no assertion that a named tool hides strikes.

Sensibull vs NSE option chain: compare the fields

The exchange chain and an analytics chain answer overlapping questions. NSE supplies a direct reference page for its contracts and documented quote columns. Sensibull's basic chain adds Greeks in its published description; its advanced tier supplies further derived measures. A trader looking only for an exchange reference and a trader wanting integrated calculations may therefore have different requirements.

That comparison should not become a claim that either source is intrinsically more accurate. A calculated field can differ because of its assumptions, while a quote can differ because the observations were made at different times. Dhan's IV help expressly identifies model and input differences, including interest rates, spot versus futures prices and refresh frequency. The explanation does not prove the cause of any specific discrepancy between two screens; the underlying observations would still need checking.

The same restraint applies to app searches. Kite's own instructions cover both web and app access. Quantsapp's pricing page links its mobile apps. This documentation does not measure app stability, screen density, notification delivery or parity of every field. A mobile listing is evidence of an access route, not a phone usability test. App usability remains untested.

If a screen's freshness matters to your workflow, the important next question is which field updated and when. See why market data can be delayed for the difference between source delivery, chart refresh and what eventually appears on a device.

What a paid chain subscription changes in these sources

Published offers checked 14 October 2026. Amounts belong to the named context, not every broker account.

Context	Published amount / condition	Chain-relevant distinction
Sensibull	Zerodha Pro: ₹0. Other-user homepage displays ₹800/month and ₹640/month presentations; term and entitlement must be checked.	Advanced chain adds fields beyond the basic chain. Exact paid bill and tax treatment are not established here.
Public Opstra	₹1,300 monthly or ₹11,000 annually, each plus 18% GST as stated by Opstra.	Free chain: 15-minute updates; Pro: live-data label qualified by the feed/calculation FAQ.
Quantsapp	Free ₹0; PRO ₹4,000/month or ₹19,999/year; PRO+ ₹8,000/month or ₹39,999/year. Published prices include taxes.	Chain at a glance on all tiers; chain what-if marked paid. This does not establish every free-chain Greek field.
Dhan Options Trader	Feature charge free for Dhan users, per support.	Broker-linked chain and execution route. Trading costs remain a separate question.

Row sources: Sensibull—sensibull and sensi-help; public Opstra—opstra; Quantsapp—quants; Dhan—dhan-free for access and dhan-web for chain execution. Opstra tax percentage is its subscription quote, not a restatement of statutory trading-charge rates. No annual Sensibull bill is inferred from a monthly presentation.

A live label can coexist with periodic open-interest updates

Public Opstra's feature table uses a live-data label for Pro. Its own FAQ then describes a one-minute feed with a few additional seconds for IV and Greeks calculations, and OI updates every three minutes. These statements should be read together. Quoting only the word live would give an incomplete account of the same provider's documentation.

Dhan's OI help similarly calls the data real-time while explaining exchange updates every one to three minutes depending on the scrip, and says the exchange does not supply continuous live OI. We attribute that cadence to Dhan's explanation; it is not an independently timed exchange-wide service guarantee. It also does not establish that every price tick, OI value and Greek share one clock.

NSE's streaming switch is a control, not a measured latency figure. A public page, paid analytics page and broker terminal may each have a different delivery path. We have not established the full feed path or end-to-end delay for each vendor. Real-time market-data costs distinguishes broker feeds, vendor subscriptions and exchange licences; a website subscription should not be assumed to include a redistribution licence or historical API access.

Paying for more analytics can change fields and update entitlements. It cannot, from this evidence alone, establish a faster browser, uninterrupted access during a busy session or superior execution. For payoff builders, historical analysis and other tasks beyond the chain, use the separate options analytics comparison.

A future expiry-session test that would support a speed claim

1. 1

   Publish the observation conditions

   Use the same contract selection, devices and network context, and identify each account tier. Proposed observation windows are 09:15–09:30 and 15:00–15:30 IST on a stated expiry-session date. These are a future method, not sessions observed for this page.

2. 2

   Capture the field and its two clocks

   Save the displayed data timestamp if supplied and the observer's capture time. A manual refresh timestamp alone is insufficient to measure feed delay. Record separate observations for price, OI and derived IV rather than one blanket speed value.

3. 3

   Record access failures without guessing their cause

   Note the login prompt, entitlement notice, loading state or unavailable field, with matching screenshots. Redact personal details. A failed login or network response does not demonstrate an exchange data defect.

4. 4

   Retain comparisons that can be reproduced

   Keep the selected expiry and strike range with each capture, and record whether a refresh was automatic or manual. Report the spread of observations rather than naming a winner from one isolated screen. No completed output from this proposed test is supplied here.

An illustrative OI unit check, not a market observation

Assume a fictional exchange display of 200 lots and a contract lot size of 50. These figures are chosen only to demonstrate the conversion described in Zerodha's help.

Exchange displayAssumed; not a captured contract.

200 lots

Quantity conversionApply the matching lot size before comparing with a quantity-based display.

200 × 50 = 10,000 units

Comparison resultNo disagreement or data-quality score follows from the unit difference.

200 lots and 10,000 units describe the same assumed OI

Keep a chain observation separate from a trading conclusion

A journal note can preserve which chain, tier and contract you looked at, the field values and units, the displayed timestamp and why you considered them relevant. That makes a later review more specific than a note saying only that OI looked strong. It does not establish that the observation caused a subsequent profit or loss, or that a calculated probability was a reliable forecast.

OneTradeJournal records trades by hand. It does not connect to the broker, import a chain, stream quotes or submit orders. Any chain context kept there must be entered manually. The comparison therefore gives no promise of automatic evidence capture, real-time verification or a trade being blocked because a field looks stale.

This documentation comparison should be refreshed when access or pricing changes. A future hands-on result needs its own dated method and retained observations. Until that work exists, documented features and unresolved questions are the limits of the comparison.

Common chain-access questions

Is the NSE option chain free?+

NSE publishes a public option-chain page with symbol, expiry and strike controls and a CSV-download control. We verified the page and its documented fields. We did not test every access boundary or measure refresh delay during an expiry session.

How often is the option chain updated?+

The provider and field matter. Public Opstra documents 15-minute Free updates; its Pro FAQ describes a one-minute feed plus calculation delay and OI updates every three minutes. Dhan describes exchange OI updates every one to three minutes depending on the instrument. These are provider descriptions, not independently measured delays for every chain.

Does Sensibull have a free plan?+

Yes. Sensibull's July 2026 help article includes Basic Option Chain in its Free plan and says Sensibull is free for Zerodha users. Its homepage separates basic and advanced chain features. Check your broker and plan access before assuming every advertised feature is free.
