Call vs Put Volume Live — Intraday Option Volume for Nifty, BankNifty & F&O Stocks
About Call vs Put Volume
Call vs Put Volume compares how many call contracts and how many put contracts actually changed hands, summed across the strike window you choose. Open interest tells you what positions are still held; volume tells you what is being traded right now. Because volume registers every single trade — opening or closing — it moves the instant traders engage a level, while open interest waits until the day's net position change settles. Volume also resets to zero every session, so every reading here is purely today's activity. We compute it live every minute during market hours (9:15 to 3:30 IST) for the expiry and strike range you select.
Interval volume vs total volume
The two charts answer different questions. The interval chart sums the contracts traded inside each candle — pick 5m and each point is the volume of those five minutes alone — so it rises and falls with the pulse of the session and makes bursts of activity obvious. The total chart accumulates every interval since the open, so both lines only climb; what matters there is the gap between them, which shows which side has dominated the day as a whole. A call line pulling away from the put line through the afternoon is a very different picture from one that opened wide and has been converging since.
Reading volume without over-reading it
Volume is direction-neutral on its own: heavy put volume can mean protective buying or fresh put writing, and the chart cannot tell you which. That is why it is best used as a confirmation and timing layer rather than a signal in isolation. A price breakout backed by a genuine call-volume burst has participation behind it; the same breakout on flat volume usually does not. On expiry day, when open interest becomes hard to read because of unwinding, volume stays clean — the strike attracting the most combined call and put volume in the final hours is frequently the settlement magnet. Note also that volume concentrates in the first and last hour on NSE, so compare a reading against the same time of day, not against the session peak.
Pair this with the Call vs Put OI chart to see whether the volume actually built positions, the Multi-Strike Volume view for the strike-by-strike breakdown, and COI PCR for the intraday sentiment read from change in open interest.
How to use the StockMojo Call vs Put Volume tool
- Select an underlying and expiry — Choose Nifty, BankNifty, Sensex or an F&O stock, then pick the expiry you trade. The nearest weekly expiry carries most of the intraday volume.
- Set the strike window — Start with ATM ± 10 strikes. Use Strike ± Range to anchor a fixed level, or Custom Strikes to isolate the strikes you are tracking.
- Pick a timeframe — 1m shows every interval and is the noisiest; 5m or 15m smooths the interval chart into readable bursts of activity. Each candle sums the volume traded inside it.
- Read the interval chart for bursts — Watch which side spikes. A call-volume burst as price pushes through a level says traders are engaging that move; a put-volume burst on a dip says the same on the downside.
- Read the total chart for the day's balance — The cumulative lines show which side has traded more overall. A widening gap means one side has dominated the whole session, not just the last few minutes.
- Confirm against open interest — Volume alone cannot tell you whether positions were opened or closed. Cross-check the Change in OI PCR or Multi-Strike OI tool to see whether the day's volume actually built positions.
Frequently Asked Questions
What is Call vs Put Volume?
Call vs Put Volume compares the number of call option contracts traded against the number of put contracts traded, summed across the strike window you choose. Unlike open interest, which counts positions still held, volume counts every trade — so it registers activity the moment it happens and resets to zero at the start of each session.
What is the difference between the Interval Volume and Total Volume charts?
Interval Volume shows the contracts traded inside each candle — a 5-minute candle sums the volume of those five minutes only, so it reads as a pulse of activity that rises and falls through the day. Total Volume is the running cumulative for the session, adding every interval since the open, so it only ever climbs. Use Interval to spot bursts of activity, and Total to see which side has dominated the day overall.
How is option volume different from open interest?
Volume counts every contract traded during the session, whether it opens a new position or closes an existing one. Open interest counts only the positions still outstanding. A strike can trade heavy volume with flat OI — that is intraday churn, traders passing the same contracts between each other. Heavy volume with rising OI means fresh positions are genuinely being built.
Why does volume lead open interest?
Open interest is a net figure that only moves when positions are actually opened or closed on balance, so it reacts slowly. Volume registers every single trade immediately. When traders start engaging a level, the volume chart shows it minutes before the OI chart confirms whether those trades built or unwound positions — which makes volume the earlier warning signal.
Is higher put volume bullish or bearish?
Volume on its own is direction-neutral: it does not tell you whether the puts were bought or sold. Heavy put volume can mean protective buying (bearish) or fresh put writing (bullish). Read it alongside the price move and the change in open interest — rising put volume with rising put OI while price holds up usually means put writing, which supports the market.
Why does volume spike at the open and the close?
On NSE, option volume concentrates in the first hour (9:15 AM to 10:30 AM) as overnight views get expressed, and again in the final hour as intraday positions are squared off. The midday lull is normal. Judge any volume reading against the same time of day rather than against the session's peak.
Which strikes are included in the volume totals?
You control it. ATM ± Range follows the ATM strike automatically and sums volume across the chosen number of strikes on each side; Strike ± Range anchors the window on a fixed strike; Custom Strikes lets you hand-pick them. A tighter range keeps the reading focused on where the real intraday activity is, while All includes every listed strike.
Why is there no previous-day comparison option?
Option volume resets to zero at the start of every session, so there is no carried-forward figure to compare against — unlike open interest, which accumulates across days. This tool is therefore always intraday: every reading is measured from today's open.
Can I see Call vs Put Volume for past trading days?
Yes. Switch to Historical mode and pick any past session — the tool rebuilds the full intraday interval and cumulative volume for that day, with the same expiry, timeframe and strike-range controls as the live view. Historical access requires a paid plan.
