Nifty Next 50 (NIFTYNXT50) ATM Straddle: What It Shows
The idea in one line
An at-the-money (ATM) straddle is one call and one put at the strike closest to the current price, for the same expiry. Its combined premium is the price the market charges for a move in either direction until expiry.
How it is calculated here
For each session we add the closing price of the call and the put at the same strike, from NSE end-of-day data. In rolling mode the strike is the one nearest the forward price that session (the same-expiry futures close, or put-call parity when no such future exists), so the chart always follows the ATM strike. You can also fix one strike from the table.
Priced-in move
The straddle premium is a rough guide to the move the options market is pricing until expiry. If the NIFTYNXT50 ATM straddle costs 250 points, the market is pricing roughly a 250-point move either way. The breakeven range is the strike plus and minus the premium.
How Traders Read the NIFTYNXT50 Straddle Chart
Steady decline
As expiry approaches, time value decays and the straddle usually falls even if NIFTYNXT50 does not move. A smooth downward slope is time decay at work.
Rising straddle
A straddle that rises is pricing more movement: either NIFTYNXT50 moved sharply, implied volatility rose, or both. Rises before results or policy events are common.
Rolling against fixed
The rolling line shows the cost of the ATM straddle whatever the price did. A fixed strike shows how one particular straddle position would have been valued day by day, which includes the effect of the price moving away from that strike.
Comparing expiries
Switch the expiry to compare a weekly straddle with a monthly one. Longer expiries cost more in points but decay more slowly per day.
Limitations
End-of-day only
One point per session from closing prices. Intraday swings in the straddle are not shown.
Not a strategy recommendation
This page describes how straddle premium has moved. It does not suggest buying or selling a straddle, which can carry large losses.
Thin stock options
For less traded stocks, closing prices of individual options can be stale, which makes the straddle line jumpy.

It is shown in the summary card above: the call close plus the put close at the strike nearest the forward price, from the latest NSE end-of-day data for the selected expiry.
What does the straddle price tell me?
It is the total premium for an at-the-money call and put, and a rough measure of the move the market is pricing until expiry.
Why does the straddle fall as expiry nears?
Options lose time value as expiry approaches. Unless NIFTYNXT50 moves enough or volatility rises, the straddle premium shrinks every day.
What is the rolling ATM straddle?
A straddle whose strike is reset every session to the one nearest the forward price, so it always tracks the at-the-money options.
How is the breakeven range calculated?
Strike minus the straddle premium to strike plus the straddle premium. It is where a straddle bought at today's close would break even at expiry, before costs.
Why does this differ from intraday charts on other sites?
This page uses one closing value per session. Intraday charts show minute-by-minute prices, but their final value for the day should match the close shown here.
