## Frequently asked questions

### What does PE-CE OI difference measure?

PE-CE difference is total put open interest minus total call open interest across the option chain. A positive and rising value means puts are being written faster than calls — bullish institutional positioning. A negative and falling value is the opposite — bearish positioning. It's a single-line sentiment gauge built from the entire chain.

### How is this different from PCR?

PCR divides put OI by call OI (a ratio). PE-CE difference subtracts them (an absolute number). The subtraction is more sensitive to large moves on one side; the ratio normalises for total OI level. Both are useful — PCR for regime identification, PE-CE difference for intraday slope changes.

### What does the slope of PE-CE tell me intraday?

The slope — how fast PE-CE is rising or falling through the session — is often more informative than the absolute level. A steepening positive slope in the first hour of Nifty trade is one of the most reliable bullish confirmations. A sharp slope flip mid-session is a reliable regime-change warning.

### Does PE-CE work for single-stock F&O?

Yes, and often with cleaner signals than indices because stock-specific OI tends to be concentrated at fewer strikes. For names like Reliance, HDFC Bank, or ICICI Bank, watching PE-CE difference ahead of results or sectoral events reveals institutional positioning clearly.

### What's the difference between PE-CE at different expiries?

Weekly expiry PE-CE reflects short-term positioning; monthly expiry PE-CE shows deeper institutional commitment. They often disagree — weekly may be neutral while monthly is strongly bullish, or vice versa. Checking both expiries gives a complete positioning picture rather than just the near-term noise.

### How do I combine PE-CE with price action?

Treat PE-CE as the leading indicator and price as the confirmation. A steepening positive PE-CE trend with price also rising is a high-conviction bullish setup. PE-CE rising but price stalling can indicate traders are positioning ahead of a breakout not yet visible. PE-CE rising while price is falling is a contrarian signal — institutions writing puts into weakness.

## How to read the PE-CE Difference chart

1. **Select symbol and expiry** — Pick Nifty, BankNifty, or an F&O stock. Check both weekly and monthly expiries separately.
2. **Check the sign** — Positive (put OI > call OI) is bullish bias. Negative is bearish bias. Zero is balanced.
3. **Watch the slope** — Rising means puts being written faster (bullish). Falling means calls being written faster (bearish). Slope direction matters more than absolute level.
4. **Identify first-hour trend** — The first hour of trade usually sets the day's PE-CE direction. A clear slope by 10:30 IST often dictates intraday bias.
5. **Look for slope reversals** — Sharp flips in slope (bullish to bearish or vice versa) often precede price reversals by 15-30 minutes.
