Most traders have some rule for losses. Very few have one for profits. They know where the stop goes, but when a trade works, the decision is made in the moment — usually by watching and hoping.
In options, that gap is expensive, because profits on an open position are exposed to forces that do not exist in the same way for shares. This article sets out exit rules for bought options, sold options and spreads.
Why profits are harder to handle than losses
Losses have a natural rule: the stop-loss. Every trading book describes it, and most traders use some version of it.
Profits have no equivalent default. The question “should I close now or could it go further?” always has the same honest answer — it could go further — which makes it impossible to settle in the moment.
Two tendencies then pull in opposite directions.
Closing too early. Many people take small profits quickly, from relief that the trade worked, while letting losses run. Over time this produces a pattern of small wins and large losses.
Holding too long. In options specifically, the opposite happens just as often. A bought option shows a good profit, the trader holds for more, and time decay and a small reversal take it away. Because the profit was never banked, it feels less painful to lose than an equivalent loss would.
Both are the same underlying problem: the exit is being decided emotionally, after the fact. The solution for both is to decide it before entering.
Bought options: time is not on your side
A bought option loses value every day through time decay, and that loss accelerates as expiry approaches. An open profit on a bought option is therefore always shrinking unless the underlying keeps moving your way.
Three rules, written at entry, handle this.
A profit level. Define it in terms of the underlying — the level your view expects — or as a multiple of the premium. When reached, close all or most of the position.
A time stop. Define a date by which the expected move should have happened. If it has not, close regardless of profit or loss. This prevents the common mistake of holding into the last few days, when decay is fastest, waiting for a move that has already had its chance.
Partial booking. Once the position shows a meaningful profit, close part of it — enough, for example, to recover the premium paid. The remainder can then run with no risk to your original capital.
For example: buy an option for 100, with a plan to exit at 200, or by the Thursday before expiry, whichever comes first. If it reaches 170 on Tuesday, sell half. The worst outcome from there is still a profit on the trade as a whole.
Sold options and spreads: the last rupee costs the most
For sold options and credit spreads, the maximum profit is fixed at the credit received, and it is earned only if the position is held to expiry with the options worthless.
The problem is the shape of the risk. Most of the premium decays in the weeks before expiry, and most of the risk arrives in the final days, when small moves in the underlying cause large swings in option prices. Holding for the last ten or twenty percent of the credit means carrying the most dangerous part of the trade for the smallest reward.
A common rule is to close at a set share of the maximum profit — often around half — and redeploy the capital, rather than holding every position to expiry.
Pair it with a loss exit. For example, close if the position's value reaches a multiple of the credit received. Without this, the profit-taking rule is only half a plan.
Watch for time as well as price. A sold position that has earned most of its available decay early in the cycle has little left to give. Closing it frees margin and removes risk without giving up much.
Trailing exits
A trailing exit moves as the trade moves in your favour, locking in part of the profit.
Trail on the underlying, not the option price. Option prices are noisy — they respond to volatility and time as well as direction, and bid-ask spreads can be wide. A trailing rule based on the option's price can be triggered by a brief widening of the spread. A rule based on the underlying's level, such as a recent swing low, reflects the view directly.
Move to breakeven first. A simple starting rule: once the underlying has moved a defined distance in your favour, move the exit so the worst case is breakeven. After that, trail in steps.
Do not trail too tightly. A trailing level too close to the current price will be hit by ordinary fluctuations and close good trades early. Base the distance on how much the underlying normally moves in the time frame you are trading.
Use the order types available. Many platforms allow orders that trigger at a price and stay active until conditions are met. Placing the exit as an order, rather than relying on watching, is what makes the rule survive a busy day.
Writing the plan, and checking it
Before any options trade, write three lines:
Profit exit: the level or amount at which you will close, fully or in part.
Loss exit: the level or amount at which you will close to cut the loss.
Time exit: the date by which you will close whatever happens.
Then record what you actually did. Over a few months, compare the plan with the results. Most traders find one of two patterns: they close winners too early, or they hold them past the point the plan said to exit. Either pattern, once seen, can be corrected.
No rule makes every trade better. Some positions closed at the planned profit will go on to rise further. The point is not to capture every rupee, but to stop correct views from turning into losses — which, across many trades, matters far more than the occasional larger win.

Frequently Asked Questions
When should I book profit in options?
At levels decided before entry: a profit level on the underlying or premium, a time exit by a set date, and partial booking once the gain is meaningful. Deciding in the moment usually leads to closing too early or holding too long.
Why do profitable option trades turn into losses?
Time decay erodes a bought option's value every day, a pause or small reversal in the underlying can remove the gain, and unbanked profit feels less painful to lose, so traders hold too long.
Should I hold a sold option to expiry for the full premium?
Often not. Most of the risk arrives in the final days while little premium remains. Many traders close at around half of the maximum profit and pair that with a predefined loss exit.
How do I trail a stop on an option?
Base it on the underlying's level rather than the option's price, which is noisy. Move the exit to breakeven after a defined favourable move, then trail in steps wide enough to avoid ordinary fluctuations.
What is a time stop?
A date by which you close a position whatever its profit or loss, because the expected move has not happened. For bought options it prevents holding into the final days when time decay is fastest.
