## Frequently asked questions

### What is price vs OI divergence in futures?

Divergence occurs when futures price and open interest move in opposite directions, signalling a regime change. A rally that continues while OI falls is running on short-covering fuel and usually stalls. A decline with falling OI is long unwinding and often near exhaustion. Divergences mark potential reversals.

### How do I read the four buildup classifications?

Long buildup (price up + OI up) is genuinely bullish with fresh longs committing. Short buildup (price down + OI up) is genuinely bearish with fresh shorts. Short covering (price up + OI down) is bullish but shorter-lived. Long unwinding (price down + OI down) is bearish but usually close to a bottom.

### Does this work for single-stock futures?

Yes. It works especially well on liquid F&O stocks like Reliance, HDFC Bank, ICICI Bank, SBIN, Infosys where OI changes are meaningful. For single-stock futures, price vs OI analysis is particularly powerful around earnings and sector rotation events.

### How is this different from the index futures price vs OI?

Index futures (Nifty, BankNifty) price vs OI reflects broad market positioning. Stock futures price vs OI reflects stock-specific flow. Both use the same four-phase framework but read different signals — index data tells you market regime, stock data tells you which specific names are being accumulated or distributed.

### When is price vs OI most reliable?

During trending sessions with clear directional bias. In tight ranges or chop, signals are noisy and can flip rapidly. Filter for moves of at least 0.3-0.5% on the underlying combined with a clear OI direction for the most reliable signals.

### What's the typical lag between OI shifts and price moves?

OI shifts often lead price by 15-45 minutes on index futures and by an hour or more on individual stocks. Institutions tend to build positions before the move, not during. Watching OI accelerate in the first 30-60 minutes of trade often predicts the session's dominant direction.

## How to read Future Price vs OI

1. **Pick an underlying** — Choose an index (Nifty, BankNifty) for macro positioning or a stock for name-specific flow analysis.
2. **Classify the current phase** — Check whether price and OI are both up (long buildup), both down (long unwinding), or divergent (short buildup or short covering).
3. **Watch for divergences** — Divergences between price and OI are the most tradeable signals — they often mark reversals before price shows them.
4. **Use first-hour signal** — The 9:15-10:15 IST window often sets the day's dominant price-OI pattern. A clear long buildup by 10:30 is high-conviction bullish for the session.
5. **Plan entry around phase transition** — The cleanest entries come at the moment a phase changes — long unwinding flipping to long buildup, or vice versa, is a high-probability reversal setup.
