Exit rules and rolling

A long option bought without an exit plan will be exited by expiration, which is the worst exit there is: it is the point of maximum decay and it converts your position into stock or into nothing. Write the exit before the entry. Here are the rules that work, and how rolling fits.

Rule 1: a profit target in the option, not the stock

Set the target as a percentage of premium or as an option price. Common choices are +50% to +100% of the premium for directional swings. The reason to target the option rather than the stock is that the option's value depends on when the move happens, and the plan has to survive that.

XYZ at $50, you buy the 60-day $50 call for $3.30. Target +75%: sell at $5.78. That is roughly a $4 to $4.50 rally if it happens within the first three weeks. If the rally comes in week seven, the same stock price gives an option worth less, and the target may never print. That is a feature: a target in option terms tightens automatically as time runs out.

With more than one contract, taking part off at the first target and trailing a stop on the rest is a reasonable middle path.

Rule 2: a time stop

Exit when a fixed number of days remain, regardless of P&L, unless the move is in progress. For a 60-day entry a common time stop is 21 days remaining; for a 45-day entry, 14 days. From the decay table in Module 3, an ATM option with 21 days left loses the remaining 60% of its extrinsic value in the final three weeks. Holding through that is paying the steepest rent for the least time.

The time stop converts "the move was too slow" from a total loss into a partial one. In the slow-rally example from the last lesson, exiting at 9 days left would have returned $0.95 of the $1.90 paid.

Rule 3: a loss stop on the option or on the stock

Two ways to set it:

• On the option: exit at −50% of premium. Simple, and it caps every loss at half the ticket. Its drawback is that a volatile stock can hit −50% on noise and then recover.
• On the stock: exit if the stock closes below a technical level that invalidates the idea. This ties the exit to the reason for the trade, which is more sensible, but the option's loss at that stock level depends on when it happens and can be more than 50%.

Either is fine; the mistake is having neither and holding a −70% option "because it can only go to zero". It can, and usually does.

Rule 4: never let it expire by default

If any of the above has not triggered by the last two trading days, close it. Long ITM options auto-exercise into stock you may not want; long OTM options are worth whatever the bid says, which is usually more than zero. The final two days are the worst risk-reward of the option's life for a holder.

Key idea: Write the profit target, the time stop and the loss stop before entering. The time stop is the one beginners skip, and it is the one that prevents the most damage.

Rolling

Rolling is closing one option and opening another in a single order (a "roll" or "diagonal" order on most platforms). For a long option there are three reasons to roll:

Rolling out (more time). Your view is intact but the time stop is approaching. Sell the 21-day $50 call, buy the 60-day $50 call. Cost: the difference in extrinsic value, which is real money. This is the correct move only if you would buy the 60-day option fresh today; if you would not, you are paying to avoid admitting the trade failed.

Rolling up (taking profit, staying in). XYZ has rallied from $50 to $56 and your $50 call is worth $6.80 (from $2.40). Sell it, buy the $55 call for $2.60. You have banked $4.20 per share, more than your original outlay, and still hold a call with delta 0.55 on the continuing move. Your worst case from here is losing the $2.60, but you are already up $4.20 net, so the trade cannot lose overall.

If the $55 call expires worthless, the whole sequence still finishes at +$1.80 per share, because the new premium was paid out of profits already realised. A common error is to treat the $2.60 as fresh risk and count the worst case as −$0.80; that double-counts the original $2.40, which the $6.80 sale already recovered. Net cash is the only number that matters: +6.80 − 2.40 − 2.60 = +1.80, and it cannot go lower.

Rolling in (closer strike, same expiry). The stock moved but not enough for your OTM strike. Sell the $55 call, buy the $52.50 call. It costs the difference in price, and it is a way of correcting a strike choice mid-trade. It is also a way of throwing good money after bad; do it only if the size question from the previous lesson now has a "yes".

When not to roll

Rolling is always available and almost always feels better than closing, because it turns a loss into "still in the trade". Ask one question: would I open the new position today, at this price, if I had no existing position? If yes, roll. If no, close, take the loss, and put the capital where you would actually deploy it.

Try it: Write a one-paragraph exit plan for a long option trade you would take: profit target in option price, time stop in days remaining, loss stop and how it is defined, and under what conditions you would roll. Put it in your trade log template so it is filled in before every entry.

Recap

• Set the profit target in option terms (+50% to +100%), a time stop (about 21 days remaining for 60-day entries), and a loss stop on the option or the stock.
• Never let a long option expire by default; close in the last two days.
• Roll out to add time only if you would buy the new option fresh; roll up to bank profit while staying in; roll in only if the size question now has a real yes.
• The test for any roll: would you open the new position today with no existing trade?
• Write the exit plan before the entry and log it.
