Sub-categories read no separate quota rather than a dash: the exchange publishes bids at that level but never a reservation against them, so a subscription multiple does not exist — it is not missing data. Bids across both exchanges (NSE and BSE) — the figure usually quoted publicly. Last updated 25 Jul, 06:06 pm IST.
How demand built
Only one reading so far. We sample subscription every hour and store it whenever it moves, so this becomes a curve as bidding runs.
