A live straddle chart shows how the combined price of the at-the-money (ATM) Call and Put changes over time. On StraddleChart you can follow NIFTY, BANKNIFTY, and other symbols in real time. This guide walks you through what to look at, in order.
Step 1: Pick index, expiry, and timeframe
Open the Straddle Chart page. Use the segment menu (Equity, MCX, Crypto) if needed, then choose your index and expiry from the dropdowns. Select a timeframe (for example 1, 5, or 15 minutes). Shorter timeframes show more detail for intraday moves; longer ones smooth noise and highlight the session trend.
Step 2: Read the ATM Straddle Price line
The main series is usually ATM Straddle Price. When this line rises, the market is paying more for that straddle—often because implied volatility is higher or because spot is moving quickly. When it falls, volatility is typically compressing or the session is quieting down. Compare the current level to the session high and low to see if premium is rich or cheap relative to today.
Step 3: Turn on Spot or Synthetic Future
Use the dataset toggles on the chart to show Spot or Synthetic Future alongside the straddle. This helps you answer: is the straddle moving because the index is trending, or mostly because options repriced (volatility)? Divergence between spot and straddle can be worth watching, but always combine with context (news, open interest, time of day).
Step 4: Overlay India VIX (when available)
If you enable India VIX, you can compare broad fear gauge to your symbol’s straddle. They often move together; when they do not, it may reflect expiry-specific or stock-specific effects. For more on that idea, see our article on India VIX vs ATM straddle divergence.
Step 5: Use zoom and crosshair for intraday
Use chart zoom and the crosshair to inspect exact times and values. This is useful around the open, event windows, and the last hour before close when straddle premium often shifts quickly.
Step 6: Pair with spike alerts (optional)
For sudden moves in premium, use Straddle Spikes to see when thresholds like 10%, 30%, 50%, or 100% are hit. That complements the chart for reaction speed.
Important reminder
