The cross-section
Hollow short-cover — 22 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.

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 | Option face valueAlso called notional, and it is NOT a book value. Every open option priced at today's spot is a face value. It overstates what is actually at stake by roughly fifty to a hundred times, because an option's price is a fraction of the underlying. A screen may show it, but must never call it a book value or imply money at risk. | Spot | Call OI | Put OI | Put wallThe strike with the most put OI (put wall = the support buyers defend) and the most call OI (call wall = the resistance sellers cap). | Call wall | Max pain | Front expiry | Expiries | Beyond front | Book notional ₹cr | Rupee gamma / 1% ₹cr | By notional | By gamma | Move | Down / up slope |

Option face value is every open call and put valued at today's spot — the SIZE of the option book. It is not money at risk, not a balance-sheet book value, and it is typically many times larger than either.
A state, not a rate: where the book sits now, never how fast it moved there.
Rupee gamma is what a 1% move does to the book's delta — the pressure a position exerts rather than the money in it. Why these two rankings disagree, and which way each written book leans →
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.
