Check if a stock is in the ban period

A stock enters the F&O ban period when the open interest in its derivatives crosses 95% of the market-wide position limit; no new positions may be created in it (existing ones may be unwound) until the open interest falls back below 80%. NSE publishes the list for the next session every evening; the desk reads it in the morning, after the close and again at 17:30, 18:30, 19:30, 20:30 IST until the next session's file is up.

Assumptions & formula

Source: NSE's securities-in-ban file (fo_secban.csv), read by the desk; the market-wide position limit rule is NSE's (95% in, 80% out).
  • The list is for the trade date the file names; from the evening the desk shows the next session's file.
