Can we place 2 Bracket orders for both BUY and SELL in Bank Nifty futures?

I have a couple of doubts that I want to clear. I’ll be thankful to those who give a minute to answer my query.

I want to know is it possible to place bracket orders for both buying and selling in Bank Nifty Futures and also in Bank Nifty options at the same time?

it could mean circular trading, which is illegal: Is it illegal to place 2 opposite futures orders in the same underlying?
