Your gateway to F&O trading
Options are the most powerful instrument available to retail traders in India. With a capital of just a few thousand rupees, you can participate in Nifty and Bank Nifty movements that institutional traders with crores are betting on. But power without understanding is gambling. This guide will turn you from a confused beginner into someone who can confidently read an option chain and place your first trade.
What Is an Option Contract?
An option is a contract that gives you the right, but not the obligation, to buy or sell an underlying asset (like Nifty 50 index or Reliance shares) at a predetermined price, on or before a specific date. You pay a small fee called the premium to acquire this right.
Think of it like booking a flat. You pay ₹2 lakh as a token amount to lock in a price of ₹80 lakh. If property prices rise to ₹1 crore, you exercise your right and buy at ₹80 lakh — a ₹20 lakh profit. If prices fall to ₹60 lakh, you walk away and lose only your ₹2 lakh token. That token amount is your premium. The ₹80 lakh is your strike price. The deadline in the agreement is your expiry date.
Call Option (CE) — Right to Buy
- You expect the price to go UP
- Gives you the right to buy at the strike price
- Profit = Spot price - Strike price - Premium paid
- Maximum loss = Premium paid (nothing more)
- Example: Nifty 24000 CE at ₹150 means you pay ₹150 per unit for the right to buy Nifty at 24000
Put Option (PE) — Right to Sell
- You expect the price to go DOWN
- Gives you the right to sell at the strike price
- Profit = Strike price - Spot price - Premium paid
- Maximum loss = Premium paid (nothing more)
- Example: Nifty 24000 PE at ₹120 means you pay ₹120 per unit for the right to sell Nifty at 24000
Payoff Diagrams: Visualizing Profit & Loss
A payoff diagram shows you exactly how much you make or lose at every possible price of the underlying at expiry. This is the most important visual in options trading — master it and everything else becomes clearer.

Options Terminology You Must Know
Before you open a single position, you need to speak the language fluently. Here are the terms you will encounter every single day as an options trader in India.
Strike Price
The pre-agreed price at which the option can be exercised. NSE offers strikes at intervals of 50 for Nifty and 100 for Bank Nifty.
Premium
The price you pay to buy an option. It is quoted per unit — multiply by lot size for total cost. A ₹200 Nifty premium = ₹200 × 25 = ₹5,000 total.
Expiry Date
The date the contract expires. Nifty has weekly (every Thursday) and monthly expiry. After expiry, the option ceases to exist.
Lot Size
The minimum quantity you must trade. Nifty lot = 25 units, Bank Nifty lot = 15 units. You cannot buy 1 unit of Nifty options.
Intrinsic Value
The real, tangible value if exercised right now. For a Call: max(0, Spot - Strike). If Nifty is at 24200 and you hold 24000 CE, intrinsic = ₹200.
Time Value
Premium minus Intrinsic Value. This is the "hope" component — the market assigns value to the possibility of future movement. Decays to zero at expiry.
ITM, ATM, and OTM — Moneyness Explained
Every option at any given moment falls into one of three categories based on its relationship to the current market price. This is called "moneyness" and it determines how the option behaves, how much it costs, and how it responds to price movements.
| Moneyness | Call Option (CE) | Put Option (PE) | Intrinsic Value | Premium Cost |
|---|---|---|---|---|
| ITM (In The Money) | Spot > Strike Nifty 24200, Strike 24000 | Spot < Strike Nifty 24200, Strike 24400 | Positive (₹200 here) | Highest (intrinsic + time value) |
| ATM (At The Money) | Spot ≈ Strike Nifty 24200, Strike 24200 | Spot ≈ Strike Nifty 24200, Strike 24200 | Near zero | Moderate (mostly time value) |
| OTM (Out of The Money) | Spot < Strike Nifty 24200, Strike 24500 | Spot > Strike Nifty 24200, Strike 24000 | Zero | Cheapest (only time value) |
Beginner Trap: New traders are drawn to cheap OTM options because they cost ₹5-10 per unit. But these options expire worthless over 90% of the time. A ₹5 Nifty option that becomes ₹50 makes a great story, but the 19 times before it when you lost ₹5 each are never mentioned. Start with ATM or slightly ITM options — they cost more but have a much higher probability of profit.
How to Read the NSE Option Chain
The NSE option chain is your command center. It shows you every available strike price, the premiums being quoted, open interest, volume, and implied volatility — all in one table. Go to nseindia.com → Derivatives → Option Chain and select Nifty or Bank Nifty.
Open Interest (OI)
Total number of outstanding contracts at a strike. High OI at a strike means that level acts as strong support (for Put OI) or resistance (for Call OI). This is the single most important column.
Change in OI
Shows fresh money flowing in or out. Rising OI + rising price = bullish. Rising OI + falling price = bearish. Falling OI means positions are being squared off.
Volume
Number of contracts traded today. High volume = active strike with tight bid-ask spreads. Avoid trading strikes with very low volume — you will get bad fills.
Implied Volatility (IV)
Market's expectation of future price movement baked into the premium. High IV = expensive options. Before events like Budget or RBI policy, IV spikes and premiums inflate.
The option chain is color-coded. ITM options are highlighted (usually yellow or blue on NSE), and the ATM strike is the one closest to the current spot price. Calls are on the left side, Puts are on the right side, and strike prices run down the center column.
Intrinsic Value vs Time Value — Where Your Money Goes
Every rupee of premium you pay for an option is split into two components. Understanding this split is critical because it tells you what you are actually paying for.
PREMIUM BREAKDOWN EXAMPLE · NIFTY 24000 CE
ATM and OTM options are 100% time value — they decay to zero if price does not move in your favor
This is why time works against option buyers. Every single day, the time value component of your premium shrinks. On the day of expiry, time value is zero — only intrinsic value remains. If your option is OTM at expiry, it is worthless. Period.

SEBI Margin Rules: For option buying, you need to pay the full premium upfront. If you buy 1 lot of Nifty 24000 CE at ₹200 premium, you need ₹200 × 25 = ₹5,000 in your account. There is no additional margin for buying. However, option selling requires significantly higher margin — typically ₹1-1.5 lakh per lot for Nifty. SEBI's peak margin rule means your broker checks margin at specific times during the day, and shortfall attracts penalties.
Who Should Trade Options (And Who Should Not)
Good Candidates
- You have a solid understanding of stock market basics
- You can afford to lose the premium without stress
- You have studied chart reading (support, resistance, trends)
- You are disciplined with stop-losses and position sizing
- You have at least ₹50,000 dedicated risk capital
- You treat trading as a skill, not a gamble
Not Ready Yet If...
- You do not understand how stock prices move
- You are using borrowed money or savings you cannot lose
- You are looking for "quick money" or "tips"
- You cannot handle losing trades emotionally
- You have never traded equity (cash market) before
- You skip learning and jump to trading
SEBI Data Reality Check: SEBI's own study found that 89% of individual F&O traders in India made losses in FY22. The average loss was ₹1.1 lakh per person. Only 11% were profitable. This does not mean you cannot be in that 11% — but it means you must take education, risk management, and discipline seriously. Do not become a statistic.
Options trading is a skill that takes months to develop. Start by paper trading (virtual money) on platforms like Sensibull or Opstra. Trade with the smallest position size possible when you go live. Scale up only after you have 50+ trades with a documented edge.
