Option chain analysis
Open interest, premium traded, IV and likely positioning by strike. Buying/writing labels are probabilistic; OI concentrations are potential (not guaranteed) support/resistance; Max Pain is theoretical.
Premium traded
- Total call premium
- ₹145 Cr
- Total put premium
- ₹153 Cr
- Put/Call premium ratio
- 1.06
- Call/Put premium ratio
- 0.94
- Net put premium

- Net call premium
- −₹9 Cr
Premium = LTP × volume × lot size. More put premium is not automatically bullish or bearish — read with price, OI change and IV.
Open interest & PCR
- Call OI / ΔOI
- 857,593 / +45,715
- Put OI / ΔOI
- 1,017,145 / +111,372
- OI PCR
- 1.19
- Premium PCR
- 1.06
- Volume PCR
- 1.20
OI PCR 1.19 (bullish) and premium PCR 1.06 (neutral) do not contradict each other.

Skew changes over 1D/1W/1M: see the “NIFTY 25Δ IV skew” indicator on Factors & Data.
Premium by moneyness (±15 strikes, ATM = nearest ±1 strike)
| ITM | ATM | OTM | |
|---|---|---|---|
| Calls | ₹42 Cr | ₹37 Cr | ₹65 Cr |
| Puts | ₹35 Cr | ₹36 Cr | ₹82 Cr |
Limiting the window to strikes near ATM stops far out-of-the-money contracts from distorting the read.
Likely buying vs writing (premium, ₹ Cr)
| Evidence suggests / likely | Calls | Puts |
|---|---|---|
| fresh buying | ₹117 Cr | ₹0 Cr |
| writing | ₹0 Cr | ₹153 Cr |
| short covering | ₹13 Cr | ₹0 Cr |
| long unwinding | ₹0 Cr | ₹0 Cr |
| no clear signal | ₹15 Cr | ₹0 Cr |
Premium pressure: calls ₹91 Cr, puts −₹129 Cr → net ₹221 Cr (+0.74 of premium, bullish +).
Price ↑ + OI ↑ → possible fresh buying · price ↓ + OI ↑ → possible writing · price ↑ + OI ↓ → possible short covering · price ↓ + OI ↓ → possible long unwinding. Volume and IV change adjust the strength of evidence. Trader intent is never certain.

Expiry positioning shift: Bullish-leaning positioning in the current expiry also appears in later expiries (near 76, later 82).
Positioning (0–100) blends OI PCR (conventional reading) with net premium pressure for each expiry, using ±10 strikes.
