I am trying to place orders from API. AT the time of placing, I am getting a successful feedback with an order number. Later I see in web interface it got rejected due to " MIS / Bo / CO orders are blocked for this instrument. Try placing a NRML/CNC ..." The fact is I have tried to place the order on 'NSE:SBIN' and 'NSE:RBLBANK' with NRML product. But still I am getting the error. When I tried to place from web, I saw this order got queued. Although I cancelled this later.
