This is a rejection code directly from the exchange. It means that you’ve placed the order at a price or time or quantity which isn’t approved.

1. Illiquid scrips in the Periodic Call Auction trade in hourly cycles, starting at 9:30. So from 9:30 to 10:15 (45 minutes) you can place orders. The exchange matches orders from 10:15 to 10:23 (8 minutes). Then there is a cool off time from 10:23 to :10:30 (7 minutes). This cycle is repeated 6 times during the day.
2. Once you place your orders, you have to wait until the 45th minute for the exchange to start the execution process. Orders will be matched on price/time priority like always.
3. If your order is not matched in a session, it will get cancelled and you have to place a fresh order again.
