Nifty 50 Straddle Chart
The Nifty 50 at-the-money straddle — call premium plus put premium — charted live from the market open. It is the cleanest single read on how far the market expects Nifty 50 to travel before expiry, and watching it decay through a session tells you more about option pricing than any static table can. A ladder of nearby strikes sits beside the chart, with spot and synthetic-future overlays available.

About Nifty 50
The Nifty 50 tracks 50 of the largest companies listed on the NSE, weighted by free-float market capitalisation and rebalanced twice a year. It is the benchmark almost every Indian equity portfolio is measured against, and its options are among the most heavily traded contracts anywhere in the world.
How to read the Nifty 50 straddle chart
The chart plots the combined premium of the at-the-money call and put — one line, from the market open through to the close. Bullmatics charts the lowest-premium strike near the money rather than a fixed strike, which is the truer at-the-money reading whenever price sits between two strikes, and it keeps the series continuous as the underlying drifts.
A straddle is long two options, so it pays time decay twice. In a quiet session the line grinds down, and that grind is the clearest picture of theta you will find anywhere. When it turns and rises instead, the market is repricing expected movement upward faster than time is running out — which is exactly the condition that hurts anyone short premium.
NIFTY is the deepest chain on this site: strikes stay liquid well out of the money, so open interest here is a genuinely informative positioning signal rather than noise. Because a weekly contract is always close to expiry, the ATM straddle collapses hard through the final session, and that decay is the single most watched number on the page.
The ladder beside the chart shows nearby strikes with their call, put and combined premiums, so you can see how the cost of a straddle changes as you step away from the money. Spot and synthetic-future overlays can be switched on to compare the premium against the underlying it is priced off.

Nifty 50 straddle — common questions
What is the Nifty 50 ATM straddle premium?
It is the at-the-money call premium plus the at-the-money put premium, added together and charted as one line. That single number is the option market's live estimate of how far Nifty 50 is expected to travel before expiry, in either direction. This page charts the lowest-premium strike near the money, which is the truest at-the-money reading when spot sits between two strikes.
Why does the Nifty 50 straddle premium fall through the day?
Because both legs are losing time value. A straddle is long two options, so it pays theta twice, and the decay accelerates as expiry approaches. If the underlying does not move enough to offset that, the premium grinds down. A straddle that rises instead is telling you the market is repricing expected movement upward faster than time is running out.
What does a rising Nifty 50 straddle premium mean?
That the market is paying more for movement than it was — either the underlying has moved sharply, or implied volatility has risen on anticipated news, or both. A rising straddle into a quiet tape is usually volatility expansion, and it is the condition that hurts short-premium positions most. NIFTY is the deepest chain on this site: strikes stay liquid well out of the money, so open interest here is a genuinely informative positioning signal rather than noise. Because a weekly contract is always close to expiry, the ATM straddle collapses hard through the final session, and that decay is the single most watched number on the page.
How much does one Nifty 50 straddle cost?
Multiply the premium on the chart by the lot size. Nifty 50 trades in one lot of 65, so a straddle premium of 200 is a debit of 13,000 rupees per lot before charges, and that is the maximum a straddle buyer can lose. A straddle seller receives it and carries theoretically unlimited risk — margin, not premium, is the binding constraint on that side.
Why is the NIFTY option chain the most watched in India?
Volume. NIFTY options are among the most traded derivative contracts in the world, which means the chain is deep, spreads are tight and open interest at a strike genuinely reflects positioning rather than a handful of trades. Signals that are noise on a thin chain — OI walls, PCR shifts, IV skew — are worth reading here.
Is this Nifty 50 straddle chart live?
Yes. Bullmatics holds one streaming connection to the exchange feed and fans every tick out to all visitors over a single websocket, so the straddle chart on this page updates in real time during market hours (9:15 AM to 3:30 PM IST, Monday to Friday). Outside those hours it shows the last completed session rather than going blank.
What is the Nifty 50 option lot size?
Nifty 50 options trade in lots of 65, quoted in rupees per index point. So a premium of 100 is worth 6,500 rupees per lot. Exchanges revise lot sizes periodically — check the current NSE contract specification before you size a position.
Do I need an account or a broker login to use this?
No. There is no signup, no broker login and no paywall. The straddle chart above is the same data every other visitor sees, streamed from one shared market connection. Bullmatics is an analytics and education tool only — you cannot place orders here, and nothing on this page is investment advice.

Nifty 50 options trade 9:15 AM to 3:30 PM IST, Monday to Friday, and the exchange is closed on its published trading holidays. The 9:00 to 9:15 AM pre-open period is not charted here — that move is reported as the day change above the chart instead.
