The order conditions possible to place are the same as at 'PRE' time(*)
(*) x_PRE_OPEN、x_PRE_CLOSE、DCB、SCB
That is, GFD Limit Order, GTD, GTC orders and FAK Market Orders.
Other than these, e.g., if an FOK Limit Order with Closing Trigger Conditions is placed, the order will be accepted but when the market migrates to x_PRE_CLOSE, it will expire without being placed in the order book.
