Arjun sold options for income. He was not reckless about it - he had read enough to use defined-risk spreads, never fully naked. For a year it worked beautifully: a few thousand rupees most weeks, drawn off a Rs 5,00,000 account. But his plan had two quiet holes. He kept no standing tail hedge, because "it just bleeds money," and he had no hard stop for a bad day, because "I'll handle it as it comes." Then one gap-down morning three of his spreads opened near their maximum loss at the same time. He froze, then "managed" the trade by adding size into a falling market - and by lunch he had given back more than four months of income. Nothing about his structures was wrong. The plan around them was.
This is the chapter the whole Option-Seller Playbook has been building toward: a concrete, ready-to-use, one-page risk plan for the income seller. Selling options forgives the least of any style in this course, so its plan must be the strictest of all.
Why the seller needs the tightest plan
Remember the shape of a seller's risk from the Tail Risk chapter. Your profit is capped - the premium you collect is the most you can ever make. Your loss is not capped in the same comfortable way. You win small and often, and once in a while you lose big. A single gap day can be larger than many months of premium. That asymmetry is the whole problem, and it means a seller cannot rely on being right most of the time. You already are. The plan exists for the rare day you are wrong.
So a seller's plan is not built to make more money. It is built so the one bad day cannot end you. Six rules do almost all of that work, and they only help if every one of them is decided before you enter, in calm, not invented mid-panic.
A seller wins by surviving. Your edge is already in the small, frequent premiums - your job is to make sure no single day, gap or volatility spike can erase a year of them. The plan is the survival, not the income.
The six rules, in order
1. Defined risk only. Every position is a spread - a short option always paired with a cheaper, further-out long option on the same side. Never naked. This is the lesson from the Naked Selling vs Hedged Selling chapter: a spread gives you a known maximum loss before you enter, while a naked short runs open-ended. Cap that defined maximum small - say no single position can lose more than 2% of capital, about Rs 10,000 on a Rs 5,00,000 account. "Defined" means known, not automatically small, so you still have to size it.
2. A margin buffer. A volatility spike raises the margin your broker demands at the worst possible moment. If you are using almost all your margin, that spike can force a square-off at the ugliest price - you get closed out at the bottom, not by choice. So deploy only part of your margin: aim to use at most 50-60% of what you have, leaving 40-50% free as a cushion. The spare margin is not idle money. It is what stops a bad day from becoming a forced day.
3. A standing tail hedge. Hold a small position in cheap, far-out-of-the-money long options at all times - the insurance from the Tail Risk chapter. It costs a little every month, maybe 0.5-1% of capital, and usually expires worthless. That is the point. On a black-swan gap it explodes in value and pays for the disaster. You keep it in the calm months precisely because you cannot predict the day you will need it.
4. Pre-set adjustment rules. Decide your adjustments before entry, not in the heat of a losing position. From the Adjustment Risk chapter: a good adjustment reduces risk; a bad one just hides a loss and quietly grows the position. Write the rule down - for example, "if my short strike is tested, I roll once or close; I never add naked size; I allow at most one adjustment per position." A rule made in calm protects you from the brave, stupid idea you will have at 9:30 on a red morning.
5. A max-loss day. Set a hard daily stop. If your total loss for the day - open plus realised, across every position - reaches a set figure, say 3% of capital (about Rs 15,000 on Rs 5,00,000), you close everything and stop trading for the day. No "let me just wait for the bounce." This is the rule Arjun did not have. It is the circuit breaker that turns a terrible day into a merely bad one.
6. Event filters. No fresh selling into a known big event. Budget day, a major central-bank decision, election results, a heavyweight earnings date - these are exactly when gaps and volatility explosions arrive. Check the calendar before every selling cycle, and simply do not open new short premium in the day or two before a scheduled shock. Hold or close, but do not sell into it.
Two of these rules - the tail hedge and the max-loss day - are the ones beginners drop first, and they are exactly the two that decide whether a gap day is survivable. The picture below shows why the hedge matters so much.
The three plan-killers are almost always the same. Naked selling - skipping the protective long because the margin is lower and the premium is higher - turns a known loss into an open-ended one. No tail hedge - dropping the cheap far-OTM longs because they "just bleed" in calm months - leaves you fully exposed on the one day that matters. No max-loss day - having no hard daily stop, so a bad morning becomes a doubling-down spiral - is how a single session erases a year. Keep all three. They are boring on 95% of days and they save you on the other 5%.
The one-page plan as a checklist
Run this before every selling cycle. If any box is unchecked, the position is not ready. Numbers are examples for a Rs 5,00,000 account - replace them with your own.
- Every short option has a defined-risk long beside it. Nothing is naked.
- My maximum loss on this position is known and is under 2% of capital (about Rs 10,000).
- If every open spread hit its maximum at once, the total stays survivable - roughly 6-8% of capital, not the whole account.
- I am using at most 50-60% of my margin. A cushion is free for a volatility spike.
- A standing far-OTM tail hedge is on right now, not "to be added later."
- My adjustment rule is written down before entry: one adjustment, roll or close, never add naked size.
- My max-loss day is set: down 3% (about Rs 15,000) and I close everything and stop.
- I checked the calendar - no fresh selling into budgets, policy meetings, elections or major results.
This is an educational example of how a seller's plan fits together, not personalised advice or a recommendation to sell options. The numbers are illustrations; your capital, risk tolerance and rules are your own.
Seller's plan vs buyer's plan
The Risk Plan for Option Buyers chapter built the opposite plan, because the two sides carry opposite risks. Seeing them side by side makes each clearer.
| Question | Option buyer | Option seller |
|---|---|---|
| Main danger | Slow bleed - premium decays to zero | One gap day erasing months |
| Biggest single rule | A premium budget you can lose fully | Defined risk only, never naked |
| Margin | Pays premium up front, little margin | Needs a margin buffer for spikes |
| The standing hedge | Is the trade - the long option is already the risk | A separate far-OTM long on top |
| Daily stop | Useful | Non-negotiable |
| Events | Can be a friend - a gap can pay you | Are the enemy - filter them out |
The buyer's plan is mostly about not over-spending on lottery tickets. The seller's plan is about not being destroyed by the rare day. Same instrument, mirror-image discipline.
When this fails
These rules shrink the seller's risk. They do not delete it. Be honest about the edges.
Defined risk can still be a big number. A spread caps your loss, but the cap can be several times the premium you collected, and several spreads at maximum on the same day add up. "Defined" is "known," not "small." If the combined defined maximum can break your account, the plan is decoration.
The hedge and the buffer cost you. A standing tail hedge bleeds a little every month and usually expires worthless. The spare margin earns nothing. Over a calm year, both drag on returns and make selling less lucrative than a back-test suggests. That drag is the premium you pay to survive - real, and worth it, but real.
A max-loss day can stop you at the worst tick. Sometimes you close everything into the panic and the market reverses ten minutes later. The hard stop will occasionally cost you a bounce. That is the price of never letting one day run unbounded, and it is a price worth paying - a missed bounce is recoverable; a blown account is not.
The gap can still exceed your hedge. On a truly extreme day, even the far-OTM long may not fully cover the move, and liquidity can be too thin to trade it at a fair price. No structure makes a black swan painless. The plan buys survival - living to sell next month - not a guarantee you walk away unhurt.
This is a map of where a seller's danger lives, not advice to sell options or to hedge in any particular way.
Quick self-check
1. Why must an option seller's plan be the strictest of all the user types?
Because the seller's gain is capped while the loss is not. You win small and often, so a single gap day can be larger than many months of premium. The plan is not for making more money - it is for surviving the rare day you are wrong.
2. What does "defined risk only" mean in practice, and why never naked?
Every short option is paired with a cheaper, further-out long on the same side, so your maximum loss is known before you enter. A naked short has open-ended loss. Defined risk also means capping that known maximum small - for example under 2% of capital per position.
3. Why keep a margin buffer instead of using all your margin?
A volatility spike raises the margin your broker demands at the worst moment. If you are fully deployed, that spike can force a square-off at the ugliest price. Using only 50-60% of margin leaves a cushion so a bad day does not become a forced day.
4. What is a max-loss day, and what do you do when you hit it?
It is a hard daily stop - a set rupee loss across all positions, for example 3% of capital. When you reach it, you close everything and stop trading for the day. No waiting for a bounce. It is the circuit breaker that turns a terrible day into a merely bad one.
5. Why decide adjustment rules before entry rather than during a losing trade?
In a losing position you are emotional, and a panic adjustment usually hides the loss while quietly growing the position - often by adding naked size. A rule written in calm ("one adjustment, roll or close, never add naked size") protects you from the brave, costly idea you will have on a red morning.
