How to read SENSEX option chain?

The SENSEX option chain shows all available options with their strike prices, premiums, open interest and volume. Calls are on the left, puts on the right. High OI at a strike indicates strong support/resistance. Use the chain to analyze market sentiment and plan your trades.

What is SENSEX open interest in option chain?

Open Interest (OI) in SENSEX option chain shows total outstanding contracts at each strike. Rising OI with rising price = bullish (long buildup). Rising OI with falling price = bearish (short buildup). Concentration of Put OI suggests support, Call OI suggests resistance.

BSE Sensex (SENSEX) Option Chain: PCR (Put-Call Ratio) at Each Strike

What is PCR in the SENSEX option chain?

PCR stands for Put-Call Ratio. In the SENSEX option chain, it is shown in the centre column next to each strike price. The strike-level PCR is calculated by dividing put OI by call OI at that specific strike. A PCR of 2.0 means there is twice as much put OI as call OI at that strike — heavy put writing, indicating strong support. A PCR of 0.3 means call OI is more than 3x put OI — heavy call writing, indicating strong resistance. The overall PCR for BSE Sensex (total put OI / total call OI across all strikes) is shown in the summary.

How to interpret SENSEX PCR for trading

For BSE Sensex, a total PCR above 1.0 is generally considered bullish — it means more puts are written than calls, and put sellers (usually sophisticated participants) are confident that SENSEX will hold above current support levels. A PCR below 0.7 signals bearish sentiment — call sellers dominate, capping the upside. For BSE Sensex, the PCR typically ranges between 0.7 and 1.5. Extreme readings above 1.3 or below 0.5 often precede reversals.

What is Volume PCR and how it differs from OI PCR

The SENSEX option chain shows both PCR (based on OI) and Volume PCR (based on today's trading volume). OI PCR reflects cumulative positioning — slower moving, better for swing trades. Volume PCR reflects today's sentiment only — faster moving, better for intraday decisions. When both agree (both above 1.0 or both below 0.7), the signal is strong. When they diverge — say OI PCR is 1.2 but Volume PCR is 0.6 — it means today's activity contradicts the overall positioning. This divergence in BSE Sensex often signals a potential shift in sentiment that hasn't fully shown up in OI yet.

Using strike-level PCR to map SENSEX's expected range

Scan the PCR column across strikes in the SENSEX option chain. Strikes where PCR transitions from above 1.0 (below the current price — put dominated, support) to below 1.0 (above the current price — call dominated, resistance) mark the equilibrium zone. This zone often predicts where BSE Sensex will settle near expiry. Strikes with PCR above 3.0 are very strong support floors. Strikes with PCR below 0.2 are formidable ceilings. Map these extreme-PCR strikes to quickly define the SENSEX trading range without any additional tools.

BSE Sensex (SENSEX) Option Chain: Column Settings and Pro Tips

Full number vs short number display in the SENSEX chain

The SENSEX option chain supports two number formats. Short format shows values like "5L" for 5 lakh or "2K" for 2 thousand — compact and fast to scan when you have many strikes visible. Full format shows the exact value like "5,00,000" — more precise but takes more screen space. For active intraday traders monitoring several strikes simultaneously, short format is preferable. For detailed analysis where exact counts matter, full format gives cleaner reads. Toggle between them based on what you are doing.

Recommended column layouts for different trading styles

For intraday scalping on SENSEX: enable OI, OI Change, LTP, Buildup, and Volume. These five columns give you fast-moving sentiment signals. For swing trading: add IV, IV Change, and Greeks (Delta, Theta). These help with entry timing and strike selection for multi-day holds. For analysis only: enable all columns including PCR, Volume PCR, Vol/OI, Intrinsic Value, Time Value, and Open HL. This gives the complete picture of BSE Sensex's option landscape. The column settings are saved per session, so you can customise the SENSEX chain for your trading style.

Sorting and pinning summary rows

The SENSEX option chain allows sorting by any column — click a column header to sort. Sorting by OI quickly shows you the most loaded strikes. Sorting by OI Change shows the most active strikes today. Sorting by Volume reveals where the highest trading activity is concentrated. The summary rows (ITM Total, OTM Total, Total) can be pinned to the top of the SENSEX chain, giving you running totals that are always visible as you scroll through strikes. Pinned totals are especially useful for tracking BSE Sensex's aggregate OI changes in real-time.

Pro tips for getting the most from the SENSEX option chain

Tip 1: Watch the Rank badges — they instantly highlight the most important strikes without scanning every row. Tip 2: Use the chart button at each strike's LTP to study intraday premium behaviour. Tip 3: Compare PCR and Volume PCR — divergence between them signals a potential sentiment shift. Tip 4: On expiry day, enable Gamma and monitor it at ATM strikes — high Gamma warns of explosive premium moves. Tip 5: Use Historical Mode to study BSE Sensex's option chain from 3-5 days before major past events. You will start recognising OI patterns that repeat. For BSE Sensex, this tool is your single most comprehensive options analysis platform. Effective as of 21 May 2026.
