Rolling

Rolling means closing an options position you already hold and simultaneously opening a new one on the same underlying stock, but with different terms — usually a later expiration date, a different strike price, or both. Instead of just letting a trade expire or closing it outright for good, the trader replaces it with a fresh version that better fits how the stock has moved or how much more time they think the idea needs.

In practice this happens as a single combined order, often called a "roll," where you buy back the option you're short (or sell the one you're long) and open the replacement leg at the same time. For example, someone who sold a call option that is about to expire and no longer likes their strike might roll it by buying back that call and selling a new one with a later expiration date, collecting or paying a net difference in premium (the price of the option) in the process.

The nuance that trips people up is that rolling is not "adjusting" a losing trade into a winning one — it is a new position with its own risk, dressed up as a continuation of the old one. The strikes and expiration change, so the breakeven points, probability of profit, and margin (the collateral required to hold the position) all change too. It's easy to roll a bad trade several times hoping the story changes, when each roll is really a fresh bet.

Rolling can move in different directions: rolling "up" or "down" changes the strike price to be more or less aggressive, and rolling "forward" (or "out") pushes the expiration further into the future, usually to buy more time for the underlying stock to move as expected.
