With calendars, since the highest premium is at-the-money (ATM) I got a signal today to roll because it was right on our strike at 55 this morning. So I put in a high bid to see if it would get filled and it did.
Bought back Feb 55 and sold Mar 55 Call for $2.00 credit
New cost basis= $2.48- $2.00= $0.48
I will add more to this post soon after my trade meeting...
