Cash-secured put exit rules: four decisions to make before you sell

The best time to decide how a put ends is before you sell it. Four rules cover almost every path: when to take the gain early, when time is up, when a roll is allowed, and when to just take the shares.

The short answer

Set four exit rules before you sell any put:

1. Profit take: close early once most of the premium is in hand.
2. Time stop: decide on a set day before expiry, so the last week doesn't decide for you.
3. Roll trigger: the exact conditions that allow a roll. Anything else, no roll.
4. Take-assignment rule: when you'll simply buy the shares, and when you'll close for a loss instead.

Written down, these turn a stressful moment into a checklist. Here's why each one exists, then one put taken down five paths.

Why decide before you sell

When a put goes against you, the screen is red and the clock is running. That's the worst time to invent a plan. People roll trades they should close, hold trades they meant to cut, and close good trades out of fear.

A rule set ahead of time takes the choice out of the moment. You're not deciding whether to act. You're checking which rule applies.

The four rules, in plain words

1. Profit take. A common habit is to place a Buy to close order for about half the premium as soon as the put is sold. If the put decays that far early, you're out. The idea: the last part of the premium takes the longest to earn and carries the most risk. Our page on buy to close shows how to place it.

2. Time stop. Pick a day, often around 21 days before expiry. On that day, look at the trade on purpose. If it's at a gain but hasn't hit your target, many sellers close it and move on. Theta speeds up near expiry, but so do the price swings of the option.

3. Roll trigger. Allow a roll only when all of these are true: - The stock is near or below the strike. - You'd still want the shares. - The roll is a net credit: the new put pays more than closing the old one costs. - No earnings date falls before the new expiry.

If any one fails, there's no roll. See rolling a put down and out for the math.

4. Take-assignment rule. If you'd still buy the shares at the strike, let assignment happen and move to the call side of the wheel strategy. If the reason you wanted the stock has broken, close the put. Many sellers also set a loss line, such as closing if the put costs about three times what they sold it for.

One put, five paths (an illustration, not a trade idea)

A made-up stock, XYZ, trades at $50. You sell a 35-day $45 put for $1.00 and collect $100. Your broker holds $4,500.

Right after selling, you place a buy-to-close order at $0.50. Your loss line is $3.00. Your time-stop day is 21 days before expiry.

Two of the five paths lose money. That's normal. The rules don't stop losses. They keep each one to the size you chose.

What the loss line saved

Look at the last row again. The news broke the reason you wanted XYZ. Without a rule, many people hold and hope.

Here's how that hope could have played out:

The loss line took −$200 and freed the $4,500 for something you still believed in. Sometimes the stock bounces after you close. That's the price of the rule, and it's usually cheaper than the alternative.

Write your rules on one card

Copy this into your trade journal before each put:

• Stock / strike / expiry / premium:
• Profit take: buy-to-close order at ____ (placed right after the sale: yes / no)
• Time-stop day: ____
• Roll allowed only if: credit, still want it, no earnings inside
• Take assignment if: I'd still buy at the strike today
• Loss line: close if the put costs ____, or if my reason to own breaks

Then follow the card, not the screen. If you break a rule, write down why. Over a few months, your notes will show which rules help and which need changing. Our first-trade walkthrough shows where these fit in the process.
