What is a straddle chart?

A straddle chart plots the combined premium of the at-the-money Call and Put at the same strike and expiry through the trading day. It is the most direct read available on what an options market is charging for movement, because holding both legs cancels direction and leaves only the cost of travel. Falling premium means theta decay is winning; rising premium means the market is paying up for volatility it now expects.

This page carries the live ATM straddle for every symbol we cover — NIFTY, BANKNIFTY, FINNIFTY, MIDCPNIFTY, SENSEX and BANKEX on the equity side, and GOLD, SILVER, CRUDEOIL and NATURALGAS on MCX. Use the symbol rail to switch between them, or open a dedicated page below for the contract you actually trade. Free and public, with no login required.

Which straddle should you be watching?

The indices are not interchangeable. Nifty is the broadest and the most liquid, and its straddle is the cleanest benchmark for Indian equity volatility. BankNifty is narrower and more concentrated, so it carries structurally higher premium and reprices harder on banking news. FinNifty sits between the two — financial-sector exposure like BankNifty, but broadened by NBFCs and insurers, and noticeably thinner in the order book.

Sensex runs on a separate exchange with its own expiry calendar and its own participants, which means its straddle is priced independently rather than being a scaled copy of Nifty's. On a day that is expiry for one index and not the other, the two charts diverge sharply even though the underlying markets are moving together.

The MCX commodities are a different market entirely. Their session runs to roughly 23:30 IST rather than 15:40, so their straddles stay live across the US trading day, and what moves them — inventory data, OPEC, the dollar, real rates — is not on the Indian calendar at all.

Reading several straddles at once

The comparison across symbols often says more than any single line. When BankNifty premium expands while Nifty premium is flat, the risk being priced is specific to banking rather than to the market as a whole. When gold expands while both equity indices are calm, something is happening in rates or geopolitics that equity volatility has not picked up yet.

Term structure is the other cross-section worth watching. Switching expiry on the same symbol shows how much more the market charges for extra time, and that spread widens visibly ahead of known events and compresses once they pass.

The straddle level alone is less informative than its behaviour. A premium that refuses to decay through a flat session is a genuine signal; the same premium decaying normally is not, even if the absolute number looks high.

What is on every chart

Each symbol's chart plots the ATM straddle premium alongside the underlying — index spot for the equity symbols, the traded future for MCX, since MCX options are options on futures rather than on a cash index. A synthetic future derived from the ATM Call and Put gives the options-implied forward for the equity indices.

A live ATM±5 option chain sits below every chart with the individual CE and PE prices and open interest that make up the straddle, so you can see whether a move came from one leg or both.

Straddle VWAP and adjustable EMA overlays are available as reference levels on any symbol, and the expiry chips on the rail switch between the available expiries for that contract.

Straddles and the strategies built on them

The ATM straddle is the base structure underneath most neutral options strategies traded in India. A short straddle is this line sold outright. An iron butterfly is the same sale with protective wings bought. A short strangle moves the idea out to OTM strikes for wider breakevens and less premium.

That makes the chart useful as a live mark on any of them. Watching your entry level against the current line tells you immediately whether a premium-selling position is working, without recalculating anything.

It is also the honest test of whether a session was worth selling into. Premium that looked generous in the morning and is still near the same level in the afternoon was not decaying — it was compensating for risk that turned out to be real.
