What is rolling an option?
In one line: Rolling is closing an option you sold and opening a new one on the same stock, at a different strike or date or both, in one order, usually for a net credit or a net debit.
How it works
Rolling is two trades sent as one. You Buy to close the option you sold. In the same order, you Sell to open a new one on the same stock.
The new one can have:
- A later date. That's a Roll out.
- A higher strike. That's a Roll up.
- A lower strike. That's a Roll down.
- Or both a new strike and a new date, like "up and out."
The order shows one net price. If the new option brings in more than the old one costs, it's a Net credit. If it costs more, it's a Net debit.
Sellers roll to avoid Assignment, to give a trade more time, or to move the strike. A roll is not a fix. It's a new trade, with new risk, that starts the moment the old one ends.
An example (hypothetical)
You own 100 shares of XYZ, bought at $50 (an illustration, not a trade idea). You sold a 30-day $55 call for $1.00 ($100). Near expiry, XYZ is at $56. The call costs $1.20 to buy back. You'd like to keep the shares.
You roll up and out: buy back the $55 call for $1.20, and sell next month's $57 call for $1.50. Net credit: $0.30 ($30). Total premium so far: $100 + $30 = $130.
| XYZ at the new expiry | What happens | Your result |
|---|---|---|
| $60 | Called away at $57 | +$700 + $130 = +$830 |
| $56 | Call expires. You keep the shares | +$600 + $130 = +$730 |
| $50 | Call expires. Shares back to your cost | +$130 |
| $44 | Call expires. Shares fell | −$600 + $130 = −$470 |
The roll bought another month of upside and $30 more. It also kept you holding the shares for another month, and the last row shows what that can cost.
Why it matters for sellers
Rolling is one of the most used tools in the wheel strategy, and one of the most misused. Before every roll, ask:
- Would I open this new trade from scratch today? If not, don't roll into it.
- Is it a credit? Paying to roll needs a strong reason.
- Am I fixing a problem or delaying it? Rolling a losing put further out can keep a loss alive for months.

Questions
Is rolling one order or two?
Most brokers let you send it as one order with two legs, so both fill together at one net price. You can also do it as two separate orders, but the prices may move between them.
Can I roll on expiry day?
Yes, while the market is open. Rolling earlier often gets better prices, since spreads widen near the close.
Does rolling avoid assignment?
It ends the old option, so that one can't be assigned anymore. The new option can still be assigned, including early.
