Tape reading, 21 October 2026: today's top 5 gainers and losers
Of today's 10 biggest movers, the stock went the first read's way from that minute to the close on 9, the other way on 1, stayed flat on 0, and 0 had no read. The list is the market's — the 5 biggest gainers and the 5 biggest losers of 214 F&O stocks by official close. For each one: the first minute any panel showed a read, the price then, and the move from that minute to the close. Every row states how much of the day was the opening gap — a flag at 09:31 cannot show a gap that happened at 09:15.

Panels read: Breakouts/Breakdowns (volume-gated level breaks), Pressure Zones, large prints on the cash tape from 09:16. "First read" is the earliest of those with a direction. "To close" is the move from the read's own minute, so a gap at the open is never counted for or against it. Prices are the official NSE open and close. Readings, not recommendations — this page shows the misses on purpose.
The same panels, live, on every NSE F&O stock — breakouts, pressure, large prints, the futures book.

Trading by the Numbers walks through the quantitative reads behind a modern F&O dashboard — order-flow imbalance, footprints, VWAP bands, OI flow, gamma structure and the expiry endgame — in plain trader-to-trader language.
