[J-GATE]When is "NCP (Non Cancel Period)"?

Would you tell us the time zone (session) when NCP (non-cancellation period) is introduced?
Category : 


To prevent excessive price fluctuation due to order modifications/cancellations just before Itayose, OSE introduces one‐minute periods during which investors cannot change or cancel their orders for certain products.
・Order Types
  • Order modifications and order cancellations
  • New orders can be placed.
・Time Periods
One minute before the opening of a day session, and
one minute before the opening and closing of a night session
The NCP is not applied to the close of the day session, but OSE introduces the restriction on the partial prohibition of large order cancellations prior to call auctions.
Non Cancel Period (JST)
  • 8:44-8:45 (M_PRE_OPEN_NCP)
  • 16:29-16:30 (N_PRE_OPEN_NCP)
  • 5:29-5:30 (the following day)  (N_PRE_CLOSE_NCP)

All contract months of the products below.

  • Nikkei 225 Futures
  • Nikkei 225 mini
  • TOPIX Futures (excluding mini-TOPIX Futures)
