This chart plots the live at-the-money straddle on MIDCPNIFTY — the Nifty Midcap Select index — through the trading session: the combined premium of the ATM Call and ATM Put at the same strike and expiry. It is the direct read on what the options market is charging for midcap movement, with direction cancelled out of the price.
The chart runs live from 09:15 to 15:40 IST on trading days. MIDCPNIFTY options trade on a 25-point strike grid — the tightest of the Indian index options — so the ATM strike rolls in small steps and the chart follows each roll. Free and public, no login required.
MIDCPNIFTY tracks the Nifty Midcap Select — a compact basket of the most liquid midcap names. Midcaps move on domestic flows, earnings and ownership shifts more than on the global macro that drives Nifty, so the volatility being priced into this straddle often has a different source than the large-cap indices show on the same day.
The index level is far lower than Nifty or BankNifty, and the 25-point strike grid matches it. Absolute premium numbers on this chart are therefore small compared with the other indices — compare shapes and percentage moves across charts, not raw levels.
Liquidity is real but thinner than Nifty and BankNifty. Quotes are wider at the ATM, and premium can appear to jump between minutes simply because the book is shallower. A single-minute spike that immediately reverts is usually the book, not the market.
The mechanics are the same as any straddle line. A falling line is theta decay working through a quiet session; a rising line means implied volatility is expanding faster than decay removes it, and the market is paying up for movement it now expects.
Because midcap moves are flow-driven, this straddle is most interesting on days when broad-market and midcap behaviour diverge: FII selling concentrated in large caps, a midcap-specific correction, or a rotation into the broader market. When the MIDCPNIFTY line expands while the Nifty line is flat, the risk being priced is specific to the midcap complex.
The most reliable signal remains the shape rather than the level. A straddle that refuses to decay through a flat session is pricing something the tape has not shown yet; one that collapses faster than usual says volatility sellers are in control.
The straddle premium is plotted alongside the index spot, so a premium move caused by spot travelling is visibly distinct from volatility repricing on its own. A synthetic future derived from the same ATM Call and Put gives the options-implied forward.
The live ATM±5 option chain below the chart shows the individual CE and PE prices and open interest that make up the straddle you are watching.
Straddle VWAP and adjustable EMA overlays are available behind the chart legend, and the expiry chips switch between available MIDCPNIFTY expiries.
