Market Segments


The Exchange operates the following sub-segments in the Equities segment:

In a rolling settlement, each trading day is considered as a trading period and trades executed during the day are settled based on the net obligations for the day.

At NSE, trades in rolling settlement are settled on a T+2 basis i.e. on the 2nd working day. For arriving at the settlement day all intervening holidays, which include bank holidays, NSE holidays, Saturdays and Sundays are excluded. Typically trades taking place on Monday are settled on Wednesday, Tuesday's trades settled on Thursday and so on.

Pursuant to the directive of SEBI to provide an exit route for small investors holding physical shares in securities mandated for compulsory dematerialised settlement, the Exchange has provided a facility for such trading in physical shares not exceeding 500 shares. This market segment is referred to as 'Limited Physical Market' (small window). The Limited Physical Market was introduced on June 7, 1999.

Salient Features of the Limited Physical Market

  • Trading is conducted in the Odd Lot market (market type 'O') with Book Type 'OL' and series 'BT'.
  • Order quantities should not exceed 500 shares.
  • The base price and price bands applicable in the Limited Physical Market are same as those applicable for the corresponding Normal Market on that day.
  • Trading hours are the same as that of the normal market and order entry during the pre-open and post-close sessions are not allowed.

The Reserve Bank of India had vide a press release on October 21, 1999, clarified that inter-foreign-institutional-investor (inter-FII) transactions do not require prior approval or post-facto confirmation of the Reserve Bank of India, since such transactions do not affect the percentage of overall FII holdings in Indian companies. (Inter FII transactions are however not permitted in securities where the FII holdings have already crossed the overall limit due to any reason).

To facilitate execution of such Inter-Institutional deals in companies where the cut-off limit of FII investment has been reached, the Exchange introduced a new market segment on December 27, 1999.

The securities where FII investors and FII holding has reached the cut-off limit as specified by RBI (2% lower than the ceiling specified by RBI) from time to time would be available for trading in this market type for exclusive selling by FII clients. The cut off limits for companies with 24% ceiling is 22%, for companies with 30% ceiling, is 28% and for companies with 40% ceiling is 38%. Similarly, the cut off limit for public sector banks (including State Bank of India) is 18% whose ceiling is 20%. The list of securities eligible / become ineligible for trading in this market type would be notified to members from time to time.

Salient Features of the Institutional segment

  • Trading in this market segment is available for institutional investors only. In order to ensure that the overall FII ceiling limits are not violated, trading members shall be allowed to enter sell orders in this market segment only for their FII clients. However, members can enter buy orders on behalf of FII/FI clients.
  • Trading takes place under series type 'IL' under market type 'N'
  • The minimum tradable quantity in this market is 1.
  • Trading shall be done on T+2 rolling settlement basis only. Settlement of transactions shall be on dematerialised mode only

SEBI also advised Exchange to develop separate segment for Intra QFI transactions in the equity shares of companies in the caution list, if QFI wish to buy without the prior approval of the depositories.
