Rolling Options
Learn what it means to roll an option, how a roll closes one position and opens another, and how changing the strike or expiration affects the trade.
What Does It Mean to Roll an Option?
Rolling an option means closing an existing option position and opening a new option position with a different expiration date, strike price, or both.
Although brokers may allow a roll to be entered as a single multi-leg order, a roll is still made up of two separate transactions.
A roll has two parts
First, the existing option is closed. Second, a new option position is opened.
The Mechanics of a Roll
For a short option position, rolling normally involves buying back the option that was previously sold and selling another option.
Step 1
Buy to Close
Purchase the existing short option back. This closes the original option position.
Step 2
Sell to Open
Sell a new option contract with a different expiration, strike, or both.
Rolling Does Not Erase the Original Trade
One of the most important concepts to understand is that a roll does not make the result of the original position disappear.
When the original option is bought back, that position is closed at whatever profit or loss exists at that time. The new option is then a new position with its own premium, expiration, strike, and risk.
Think of a roll this way:
Original Position
Closed
New Position
Opened
Rolling Out
Rolling out means moving the position to a later expiration date.
Current Expiration
Oct. 9
New Expiration
Oct. 16
Added Time
7 Days
Moving to a later expiration adds time to the new position. That additional time may allow the new option to contain more time value, but it also means remaining in the trade longer.
Changing the Strike
A roll can also change the strike price. For a cash-secured put, a trader may sometimes move the strike lower when opening the new position.
Current Put Strike
$70
New Put Strike
$67
Strike Change
-$3
A lower put strike reduces the price at which the seller would be obligated to purchase shares if assigned on the new contract. However, the new position still carries market and assignment risk.
Rolling for a Credit
A roll produces a net credit when the premium received from the new option is greater than the amount paid to close the old option.
Example
Buy Back Old Option
$90
New Premium Received
$125
Net Roll Credit
$35
$125 received − $90 paid = $35 net credit
This is a simplified example and does not include commissions, contract fees, taxes, or other transaction costs.
Rolling for a Debit
Not every roll produces additional premium. If closing the old option costs more than the premium received from the new option, the roll results in a net debit.
Buy Back Old Option
$150
New Premium Received
$120
Net Roll Debit
$30
$120 received − $150 paid = -$30
A debit is additional money paid during the roll. That cost should be included when evaluating the overall position.
A Credit Does Not Automatically Make a Roll Good
Receiving additional premium can make a roll look attractive, but the amount of credit is only one part of the decision.
What You Receive
The new option may provide additional premium and possibly a different strike.
What You Accept
The new option also creates a new obligation and extends market exposure until the new position is closed or expires.
A roll should be evaluated as a new trade rather than judged only by whether it can be entered for a credit.
Why Might an Option Seller Roll?
There are several reasons a trader may consider rolling an option position.
Add More Time
Moving to a later expiration gives the new position more time.
Change the Strike
A new strike can change the price at which assignment would occur.
Collect Additional Premium
Some rolls can be completed for a net credit.
Continue the Position
The trader may still be comfortable with the underlying and want to continue using the strategy.
Evaluate the New Trade
Because a roll opens a new option position, the new contract should be evaluated on its own merits.
Questions to ask before rolling
Would I be comfortable opening this new option if I did not already have the current position?
What is the new strike price?
How much additional time am I adding?
What is the delta of the new option?
Does the roll produce a credit or a debit?
How much total premium has been collected across the position?
Am I comfortable with assignment at the new strike?
Does extending the trade still fit my original plan?
Rolling and the OptionEdge Approach
The OptionEdge approach treats rolling as a management tool, not as an automatic response whenever an underlying moves toward the strike.
Before rolling, the new position should make sense on its own. Moving a trade simply to avoid assignment or avoid recognizing a loss can create a position that no longer fits the original strategy.
Review the Strike
Make sure the new strike still represents an assignment price you are prepared to accept.
Review the Time
Understand how many additional days are being added to the position.
Review the Credit
Calculate what you are paying to close and what you are receiving from the new option.
Common Rolling Mistakes
Thinking that rolling erases a loss on the original position.
Looking only at the new premium without considering the cost to close the old option.
Rolling automatically whenever the underlying approaches the strike.
Accepting a new strike that does not fit the trader's assignment plan.
Adding significant time to a trade without considering the additional market exposure.
Assuming every roll should produce a credit.
Judging a roll only by the amount of credit received.
Rolling repeatedly without evaluating whether the new trade still makes sense.
Key Takeaways
Rolling closes an existing option position and opens a new one.
A roll can change the expiration date, strike price, or both.
Rolling does not erase the profit or loss on the original position.
A roll produces a credit when the new premium exceeds the cost of closing the old option.
A roll produces a debit when closing the old option costs more than the new premium received.
A credit does not automatically make a roll a good trade.
The new option should be evaluated as a new position with its own risks and obligations.
Rolling is a management tool, not a requirement when a trade moves against you.
