The cross-section
Most put-heavy in its own history — 42 of 213 namesSource: NSE F&O open interest · NSE F&O open interest by expiry · fno_option_strikes.
Across 213 current F&O stocks, the latest one-month paths separate into directional, two-way and range regimes. The number beside a stock measures how cleanly its realised path fits that bucket; it is not the probability that the next month repeats.

In plain EnglishEvery symbol opens the same movement object inside its stock dossier. The buckets use the stock's own return and range history; a fixed 5% move is not treated as equally unusual for every name.

Ran and found nothing on this tape: Fresh long on a thin book. A check with no names is a reading, not a gap.
Ranked by how crowded the futures book is versus this name's own history, highest first. Names with the same value are listed A–Z.
| # | Symbol | Positioning | Held | OI pctl | PCR pctl | Max-pain pctl | PCRTotal put OI ÷ total call OI. >1 = more puts open than calls (hedging / contrarian floor); <1 = call-heavy. A sentiment read, not a verdict. | Futures OICounted in SHARES, not in contracts and not in rupees. It is the exchange's own figure for how many shares' worth of a contract are still open, summed across expiries. A raw reading of a few hundred million is therefore normal, and means shares. | Basis | vs max-pain |

In plain EnglishEach column group is one of the reads this workspace used to keep on its own tab. They are the same reads — the percentiles, the quadrant and the streak are the board's own engine, the option figures, the expiry split and the economics ranks come from each family's own source. What changed is that they arrive on one row.
