The cross-section
Crowded short build-up — 12 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.

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.
