PCR extreme timing
The put-call ratio measures how much traders are buying puts relative to calls. This strategy treats an unusually high or low daily PCR, judged against its own one-year history, as a sign the crowd has leaned too far one way. It then trades NIFTY futures against the crowd and holds for a fixed few sessions, the horizon over which PCR has been found to lead the index.How it trades

PRE-BUILT · DEFAULTSWhere it made and lost money
With only 19 trades, most conditions are too thin to judge, but two splits stand out in this test. Trades entered while NIFTY was below its 20-day average made ₹70,031 over 11 trades: heavy put buying after a fall was often followed by a bounce, which is the contrarian idea at work. The 8 trades in an uptrend lost ₹26,977, when an extreme reading reflected a market that kept going. Trades entered on weekly expiry day made ₹44,349 over 9 trades, while the other 10 lost ₹1,296, possibly because expiry-day option volume exaggerates the PCR extreme before it unwinds.
About this strategy
- At each session's close, add up put volume and call volume across the three nearest NIFTY option expiries and divide to get the day's PCR.
- Compare it with the last 250 sessions: work out how many standard deviations today's PCR sits from the average (its z-score).
- If the z-score is +1.5 or higher, the crowd is heavily hedged: plan to buy one lot of the near-month NIFTY future.
- If it is −1.5 or lower, the crowd is complacent: plan to sell one lot.
- Enter at the first price of the next session; ignore new signals while a trade is open.
- Close at the end of the third session, counting the entry day. If the futures contract expires first, roll into the next month for the rest of the hold.
- There is no stop loss and no target.
Why traders use it
PCR is one of the most watched sentiment gauges in Indian markets. The contrarian reading is that when everyone is buying puts, much of the fear is already priced in and the market tends to bounce; when call buying dominates, the opposite. Using a z-score against a year of history adjusts for the PCR's normal level drifting over time, so only genuine extremes trigger. Research has linked volume PCR to moves over a few days and OI PCR to moves over about two weeks.
The year in plain words
On NIFTY from 1 Oct 2025 to 30 Sep 2026 with default settings, the strategy made 19 trades, rolls included, and won 47% of them for ₹43,053 before costs, a profit factor of 1.42. Results were lumpy: average wins of ₹16,143 against average losses of ₹10,223, with January (+₹38,363) and July (+₹32,598) offset by June (−₹36,601). Maximum drawdown reached ₹36,601. Because it trades a single futures lot a handful of times, costs were small and the after-costs result was ₹35,986. With so few trades, the outcome rests on a few large moves.
What the settings do
Risks
- There is no stop loss, so a futures position can lose heavily if the index keeps moving against it for three sessions.
- Nineteen trades is a very small sample; one or two large moves decide the year.
- Weekly expiries dominate option volume and can distort the PCR on expiry-heavy days.
- Holding overnight exposes the position to gaps on global news.
Who it suits
Swing traders who follow sentiment indicators and can carry a NIFTY futures position for a few days without a stop, with enough margin and tolerance for large swings in P&L.
Questions traders ask
How is PCR used as a contrarian indicator?
A high put-call ratio means many traders are buying puts, usually out of fear or for protection. Contrarians read that as a crowded bearish view that is likely to unwind, which can lift the market. A very low PCR is read the other way. The signal is about extremes, not everyday readings.
Is the PCR extreme strategy profitable?
In this backtest on NIFTY futures from 1 Oct 2025 to 30 Sep 2026 it made ₹43,053 before costs and ₹35,986 after ₹20 per order and bid-ask slippage (statutory charges not included), from only 19 trades and with a ₹36,601 drawdown. Past results do not guarantee future ones.
What is the difference between volume PCR and OI PCR?
Volume PCR compares the puts and calls traded during the day, so it captures fresh activity. OI PCR compares open positions, which build up over days. Research suggests volume PCR leads the index over a few days and OI PCR over roughly two weeks, which is why the holding period differs.
Why use a z-score instead of a fixed PCR level like 1.3?
The normal PCR level shifts over time as products and participants change. A z-score measures how unusual today's reading is against the last 250 sessions, so the threshold adapts instead of relying on a fixed number that may be ordinary in one year and rare in another.
