Why my market orders placed in BSE and NSE are getting cancelled?

---

The market orders placed in BSE and NSE get cancelled in the below three scenarios: 

• If the Market order placed does not have any counter orders
• If the order was modified from Limit to Market order and there are no counter orders,
• If the market order is out of range. 
• Capital Market (CM) / Cash Segment: Price Band Limitation:
  If you encounter this error while placing a regular stock trade in the cash segment, the error message means, "Order price is outside the revised price range."

The NSE automatically dynamically adjusts (flexes) its price bands for highly volatile stocks throughout the day. If you place a limit order at a price that falls outside the active sliding price band, the exchange automatically cancels or rejects your order and triggers this error

The order status codes for these cancelled orders will be CLBV or PECLBV
