Why is the rejected order not displayed in the order book ?

An additional layer of order validation has been incorporated to enhance order processing speed on CubePlus. This layer rejects orders that do not meet specific criteria, and although such orders do not appear in the order book, the rejection reason can be viewed in the order status notification.

The following rules govern the order validation process:

Freeze Quantity: Validates F&O orders exceeding the freeze quantity.

Intraday Orders: Validates intraday orders for stocks on NSE and BSE, ensuring compliance with MIS/CO. Refer to the list of instruments allowed for intraday.

Trigger Price: Validates orders with trigger prices lower than LTP for buy orders and higher than LTP for sell orders.

Market Orders for Stock Options: Blocks market orders for stock options due to illiquidity.

AMO Orders: Blocks AMO orders placed between 9:15 AM and 4:00 PM for EQ and FO, 9 AM to 5.30 PM for CDS, and 9 AM to 12 Midnight for Commodity.

Orders Placed Beyond Circuit Limits: Blocks orders placed beyond circuit limits and price bands.

Order Quantity Greater Than 1,00,000 Shares: Blocks orders with a quantity exceeding 1,00,000 shares.

Stocks in Exchanges’ Watchlist for Unsolicited SMS Tips: Buy orders are blocked for stocks listed in the exchanges’ watchlist for unsolicited SMS tips circulation.
