What is Option Selling?

Option Selling means that rather than buying options, you choose only to sell options as your trading strategy. For example, if you expect the market or index to go up in the near term, you decide to sell put options rather than buy call options (like most retail traders do).

The issue here is that Option Selling requires a higher margin and a different trading style. Also, it has limited profit potential and higher risk. We will look into all these aspects in this post. Keep reading.

Why Option Selling is the better way to make consistent money

Trading is a game of probability. When you trade on your trading system, there is always a probability of your trading going in profit or loss. So, when you work on your trading system, you increase your probability of being profitable.

When you buy an Option, you get your profit only when the momentum of the market is in your favor. In comparison, your option will lose value if the market is at the same level or if it goes against you. This means the probability of success is 33% when you are an option buyer.

Whereas Options Selling is more profitable as compared to option buying. Because you are profitable in two out of three scenarios.

Benefits of Option Selling for Indian Traders

Let me share the benefits of options selling specifically for Indian traders, keeping in mind the unique aspects of our markets.

From my experience trading options in Indian markets since 2008, I’ve observed some distinct advantages that make options selling particularly attractive for Indian traders:

Premium Collection Aligned with Indian Income Patterns

The regular premium income from options selling aligns well with the Indian mindset of monthly income generation.

For instance, a trader with a ₹10 lakh portfolio can potentially generate 1.5-2% monthly income through systematic option selling – that’s about ₹15,000-20,000 per month.

This steady income pattern is similar to receiving rental income, which many Indians are familiar with.

Market Infrastructure Advantage

Our options markets, particularly in indices like Nifty and Bank Nifty, are highly liquid and well-regulated by SEBI. The weekly expiry format introduced in recent years gives traders more flexibility in managing positions.

For example, you can sell a Nifty option on Monday and choose to close it by Wednesday if you’ve made decent profits rather than waiting for the monthly expiry.

Lower Capital Requirements

One beautiful aspect of the Indian options market is the smaller contract sizes compared to global markets. Take Bank Nifty options – with a margin requirement of around ₹1,00,000-1,40,000 (varying based on bank nifty spot value), even retail traders can start options selling.

Tax Efficiency

For Indian traders, options income is typically classified as business income rather than capital gains (consult your CA for specific cases). This allows for the deduction of trading-related expenses like software subscriptions, internet charges, and even home office setup – something many new traders don’t realize.

Risk Management Friendly

Our markets have robust risk management systems with daily M2M settlements and circuit filters.

Plus, most brokers now offer sophisticated platforms where you can set automated stop losses.

I remember in 2009-10, We had to manually track positions – the technology evolution has made risk management much more efficient now.

The key is to start small, understand these benefits in your specific context, and gradually scale up as you gain confidence in options selling strategies.

How Options Work: A Quick Refresher

Think of options like an insurance policy for stocks – but one that can be bought and sold by anyone. Let me explain with a real-world example I often use in my training sessions:

Consider Reliance Industries trading at ₹2500. You have two main types of options:

Call Options:

The Right to Buy Imagine you’re interested in buying a flat, but prices are high right now. You pay a token amount (say ₹2 lakh) to the builder to lock in today’s price for the next 3 months. That’s exactly how a call option works.

For instance:

  • You pay a premium of ₹50 to buy a Reliance 2600 Call option
  • This gives you the right (not obligation) to buy Reliance at ₹2600 (strike price)
  • If Reliance goes to ₹2700, you profit ₹100 (minus the ₹50 premium paid)
  • If it stays below ₹2600, you lose only the ₹50 premium

Put Options:

The Right to Sell Think of this as a price protection guarantee. Like when you buy a smartphone, and the store promises to pay back the difference if prices drop within 30 days.

Using the same Reliance example:

  • You pay ₹45 premium for a 2400 Put option
  • This gives you the right to sell at ₹2400
  • If Reliance falls to ₹2300, you make ₹100 (minus the ₹45 premium)
  • If it stays above ₹2400, you lose only the ₹45 premium

Key Terms You Must Know:

Premium: This is your cost of buying the option. Like insurance premiums, it’s non-refundable.

I’ve seen many new traders get confused here – remember, when selling options, you receive this premium.

Strike Price: The price at which you can exercise your option. I like to call it the “promise price.” In our Reliance example, 2600 for Call and 2400 for Put are strike prices.

Expiry: The date until which your option is valid. In India, we have weekly and monthly expires.

Post expiry, the option becomes worthless – just like your movie ticket becomes useless after the show timing.

Pro Tip from My Trading Experience: One mistake I often saw new traders make during my mentoring sessions – they focus too much on premium without understanding strike selection.

Remember, cheaper isn’t always better. A ₹10 premium far-strike option might be cheap for a reason!

Three Scenarios of the stock market

Scenario 1 – Bull Market

Scenario 2 – Bear Market

Scenario 3 – Consolidating market (70-80% of times market is in this zone).

Money-making scenarios of Option Selling

Scenario 1: When the market moves in your direction.

It’s a no-brainer, you sell a put, and the market moves up. Puts lose money, and you are in profit.

This scenario is true even if the market moves slowly in your direction. Because even if the market or the stock is staying at the same levels, you will make money, as explained in scenario 2.

Scenario 2: When the market or the stock doesn’t move (consolidating)

This is the most common scenario. You see a move, you enter a trade, and the stock or the market keeps moving in a range. Most traders lose patience after waiting a few hours or even days for the trade to move in their direction.

But, as an option seller, you are in a sweet spot here. Because even when the stock price is not moving, the option prices lose time value.

So, you see, in option selling, you have two out of three market scenarios working in your favor.

How to start in Option Selling

With the word Option Selling, it seems as if the only thing you need to do is to sell the option rather than buy it.

But, in reality, it’s not this simple. And the reason is the risk factor involved in selling an option.

What is the risk factor in Options Selling?

When you sell an option, you are expecting the premium of that option to go down. For example, if you sell a bank nifty option at a premium price of ₹ 230, you expect the price to go down below 230 (ideally as close to zero as possible).

This means the maximum profit you can earn from this trade is 230*25 = 5750/-. Whereas, if the premium price rises above 230, you will start losing money on this trade.

Thus, the main risk in the Options Selling trading style is that the profit side is limited but the losing side is theoretically unlimited.

The question here is, then why are options selling still considered to be a more consistent and profitable way to earn money in trading?

The reason for this is simple – as mentioned above – the probability of you being right and ending up in profit is higher in selling options than buying options. But, this depends on the trading strategy you decide to use for your option selling strategy.

Here in the next part, we will discuss the same –

Options selling trading strategies can be divided into two broad segments:

  1. Hedging based Options selling – for risk-averse traders
  2. Direction Option Selling – for discretionary traders

Hedging-based Options Selling Strategies

Heding-based Options Selling strategies are also called neutral trading strategies. These strategies are not concerned with bearish or bullish views about the market.

Instead, these strategies are focused on a range of instruments. In the Indian Stock market, these strategies are mainly used for Index Options ( Nifty and Banknifty).

  1. Straddle
  2. Strangle
  3. Butterfly

Directional Options Selling Strategies

Discretionary traders do Options Selling based on their view about the market movement. For those who don’t know, a discretionary trader is one who trades based on his view of the market. When you trade by looking at chart patterns (technical analysis), that is discretionary trading.

So, if the view about the market is bullish, then put option selling is done and if it’s bearish, then call option selling.

Thus directional option selling is similar to what we hear about trading in general. You trade based on your observation of the market. The most popular way of doing such option selling is to sell options using support and resistance levels.

How to choose the right strike for Option Selling

When you buy an option, your only total risk is the premium you paid for buying that option, so you can simply buy an option based on a near enough strike and as per your trade capital.

Whereas in the case of Option Selling, if you choose the wrong strike to sell, then risk can increase exponentially. So, choosing the right option strike to sell is very important for an Option Selling based trading strategy.

The most common method of choosing the Options strike to sell is to use support and resistance levels. This means that if you are selling a call option, you sell the strike either at the resistance level or just above the resistance level.

How much capital is required for selling options (Banknifty and Nifty)

As when you sell an option, profit is limited but chances of loss are unlimited, the margin required for selling an option is quite high. As per the Zerodha margin calculator, the margin required for selling a single lot of Banknifty option is around ₹ 1.43L.

Option Selling: In-Depth Complete Guide 1

This is an approximate figure, depending on the volatility of the overall market.

How to reduce the margin required for selling index options

As you just noticed, the margin requirement for selling 1 lot of option is nearly equal to trading in 1 lot of futures. Now, if we compare this to the margin required to buy 1 lot of option, the difference is quite high.

The reason for the same is that when you buy 1 lot of option, you only pay the premium for that option.

For example, let’s say, the BankNifty option of 43000 strike is trading at price ₹ 200, then to buy 1 lot of this option will be

25(size of 1 lot of Banknifty)*200 = ₹ 5000 only.

Whereas to sell the same, you will need around ₹ 1.4L of margin amount in your trading account.
