Option Selling Strategies – Complete Guide1. Introduction to Option Selling
Option selling, also known as option writing, is a strategy where a trader sells (writes) options to earn premium income. Unlike option buyers, who need a strong price move to profit, option sellers benefit when the market moves sideways, slowly trends, or even slightly moves against them.
In option selling, time decay (Theta) works in your favor. Every passing day reduces the option’s value, allowing sellers to profit even if price does nothing.
However, option selling involves high risk if not managed properly, which is why it is considered a professional strategy, best used with strict risk management.
2. Why Traders Prefer Option Selling
Most professional traders prefer option selling because:
• Higher probability of profit (60–80%)
• Income generation through time decay
• Works best in range-bound markets
• Consistent returns if risk is controlled
Statistically, options expire worthless most of the time, which benefits sellers.
But remember:
Option selling gives small, consistent profits but can lead to large losses if risk is ignored.
3. Key Concepts Every Option Seller Must Know
Before strategies, you must understand:
a) Time Decay (Theta)
Time decay accelerates in the last 2–3 weeks before expiry. Sellers earn as option value melts daily.
b) Implied Volatility (IV)
• Sell options when IV is high
• Avoid selling when IV is extremely low
High IV means higher premium.
c) Margin Requirement
Option selling requires large margin, especially naked selling.
d) Risk Management
Never sell options without a hedge unless you’re highly experienced.
4. Popular Option Selling Strategies
4.1 Short Call (Naked Call Selling)
Market View: Bearish or sideways
Instrument: Sell Call option
How it Works:
You sell a call option expecting the price to stay below the strike price.
Example:
NIFTY at 22,000
Sell 22,200 CE
If NIFTY stays below 22,200 → profit = premium received.
Pros:
• High probability
• Fast premium decay
Cons:
• Unlimited loss if market rallies
• Requires high margin
👉 Best for experienced traders only.
4.2 Short Put (Naked Put Selling)
Market View: Bullish or sideways
Instrument: Sell Put option
How it Works:
You sell a put option expecting the price to stay above the strike price.
Example:
NIFTY at 22,000
Sell 21,800 PE
If NIFTY stays above 21,800 → profit = premium.
Pros:
• Works well in rising markets
