Introduction
Option sellers (also called writers) earn money by collecting premium. They profit when the market stays in a range or when time decay (theta) eats into option prices. But markets don’t always behave.
When Nifty or Bank Nifty moves sharply towards your sold strike, doing nothing can turn a small profit into a large loss. An option selling adjustment is a planned change to a running position that reduces risk or restores balance, so you don’t have to exit in panic.
Why Adjustments Matter
- Option sellers have limited profit (the premium) but potentially large losses.
- Weekly expiries on Indian indices move quickly, so problems grow fast.
- A pre-decided plan removes emotion from trading.
When Should You Adjust?
Set your trigger before entering the trade. Common triggers:
- The index comes within 100-150 points of your sold strike.
- The sold option’s premium doubles.
- The loss reaches a fixed limit (for example, 1.5x to 2x the premium collected).
- Delta of your sold option rises sharply (e.g., above 0.40-0.50).
Popular Adjustment Techniques
| Technique | What You Do | Best Used When | Drawback |
| Rolling the strike | Close the threatened option and sell a further-away strike | Trend is moving against you | May add cost or reduce premium |
| Rolling to next expiry | Close the current option and sell the same/farther strike in the next expiry | Need more time for the trade to work | Higher margin blocked |
| Adding a hedge | Buy a far OTM option to cap loss | Sudden volatility or event risk | Hedge cost eats profit |
| Converting to a spread | Buy a farther option on the threatened side | Want defined risk | Reduces maximum profit |
| Rolling the untested side closer | Shift the safe side nearer to collect extra premium | Market has reversed, and the untested side is nearly worthless | Narrows your safe range |
| Exiting the position | Close the trade | Stop-loss hit or thesis is broken | Locks in the loss |
Simple Example: Short Strangle on Nifty
(Numbers are illustrative.)
- Nifty is at 24,500. You sell a 24,900 Call and a 24,100 Put at ₹60 each, collecting ₹120 in total.
- Nifty rises to 24,850. The Call is now worth ₹150, and the Put has fallen to ₹15.
Possible adjustment:
- Buy back the 24,900 Call at ₹150.
- Sell the 25,200 Call at ₹70.
- Optionally, buy back the cheap Put and re-sell it closer for extra premium.
This gives the market more room and reduces the pressure on the trade. Remember that each adjustment adds brokerage, taxes and slippage.
Golden Rules for Every Option Selling Adjustment
- Adjust early, not late. Fixing a small problem is cheaper than fixing a big one.
- Don’t add lots blindly. Doubling your position to “recover” is how accounts get wiped out.
- Check margin. Rolling or adding legs can raise your margin requirement.
- Limit the number of adjustments. Two per trade is a sensible cap. After that, exit.
- Prefer hedged strategies. Iron condors and credit spreads have built-in protection, which makes adjustments easier.
- Avoid adjusting during expiry-day chaos. Prices swing wildly, and slippage is high.
Common Mistakes to Avoid
- Adjusting without a written plan
- Selling naked options without enough capital buffer
- Ignoring events such as RBI policy, the Union Budget, election results and global cues
- Holding losers hoping for a reversal
- Overtrading and paying excessive transaction costs
Quick Checklist Before Adjusting
| Question | Yes/No |
| Has my pre-set trigger been hit? | |
| Do I know my maximum acceptable loss? | |
| Do I have enough margin? | |
| Will this adjustment reduce risk, not just delay the loss? | |
| Have I accounted for costs and taxes? |
Conclusion
Adjustments are not about avoiding losses entirely. They are about keeping losses small and controlled. Start by practising on paper trades, keep position sizes modest, and stick to your rules. Consistency and discipline matter more than any single clever adjustment.
