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. ## How to use the StockMojo Call vs Put Volume tool 1. **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. 2. **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. 3. **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. 4. **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. 5. **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. 6. **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. ## Related tools - [Call vs Put OI](https://stockmojo.in/call-vs-put-oi) — markdown: https://stockmojo.in/call-vs-put-oi.md - [Multi-Strike Volume](https://stockmojo.in/multistrike-volume) — markdown: https://stockmojo.in/multistrike-volume.md - [COI PCR](https://stockmojo.in/change-in-oi-pcr) — markdown: https://stockmojo.in/change-in-oi-pcr.md ## Glossary Terms used: volume, open-interest, put-call-ratio.
