Bracket order for delivery order

If I donot trade intreday,can I still place a bracket order with SL,TP,trailing SL if its a delivery order ?

BO is only for Intraday squareoff. Orders placed through BO will not result in delivery of shares.

Any way ,as of now,to set trailing stop loss for delivery orders, or cant ?

NOPE, you can keep updating your CNC-SL(SLM) order.

one more query- in zerodha,if i set a fixed stop loss,do i have to set it daily or will it be there till the trade gets completed ?

Yes, each day stop loss needs to be setup. Unexecuted stop loss will automatically get cancelled post 3:30 pm.
