I hear you,know where you are coming from,but "who cares" about the roll....
What I am saying is you are managing your current position, i.e the Greeks...
Once you roll,it's an entirely new bet that stands on its own. Im assuming you have levels where you adjust or close the position based on whatever voodoo one chooses.
Where and what priced you rolled at is meaningless.
I haven't traded a spread in so long I forget how the calculate rolls...
If this is the scenario
Buy call for 1
Sell call for .88
pnl: -.12
If the new position you want to roll out to is @ 1.50 then what is the cost of the roll, and what does your new position look like?
When you trade in (roll out a car)...the dealer will just give you the cost of the new vehicle - the trade in price. He doesn't factor in the cost you paid for the car originally, but it is relevant to you since you need to add that cost to the deal. So you paid 25k, the dealer gives you 20k and the new car is 30k.
Contract cost: 10k
Your cost: 15k
