Spread order position rollover

How can I rollover my hedge position in expiry day, while entering hedge position I used spread order, long in current month and short in next month ,

You would rollover a spread position in a similar fashion to rolling over a regular position. First, you have to square off your existing position - since you're holding a spread position, use the spread order window to exit this position. Once you've exited your current position, you can enter into a new spread. Brokerage and other charges will be applicable for rolling over a position.
