Options trading is buying and selling contracts that give you the right, but not the duty, to buy or sell an asset at a fixed price before a set date. In India, most options trading happens on indices like the Nifty 50 and the Sensex.
A call option gains value when the price of the asset goes up.
A put option gains value when the price of the asset goes down.
The buyer pays a price called the premium, and the seller collects it and takes on the risk.
Options let you take a position with less money than buying the asset outright. The same feature makes losses add up fast, so it pays to test an idea on past data before real money goes in.

How Options Trading Works
An option is a contract between two people. The buyer pays the seller a premium. In return, the buyer gets a right that lasts until the expiry date.
The asset the option is based on is called the underlying. It can be an index like Nifty 50 or a stock like Reliance.
A Simple Example
Say Nifty is trading at 26,000 and you think it will rise this week. You buy a 26,100 call option.
You pay the premium for every unit in one lot, and one Nifty lot is 65 units.
If Nifty climbs well above 26,100 before expiry, the call gains value and you can sell it for a profit.
If Nifty stays below 26,100, the call loses value and can be worth zero at expiry.
As a buyer, the most you can lose is the premium you paid. You do not need to hold the option until expiry. Most traders sell it back in the market before that.
Call Options vs Put Options
Every option is either a call or a put. On Indian platforms you will see them written as CE (call) and PE (put).
CE and PE stand for “Call European” and “Put European”. European options can only be exercised at expiry, though you can buy or sell them any time before that.
Options Terms Every Beginner Should Know
You will see these words on every trading screen. Learn them once and the rest of options trading gets much easier.
The premium is the price of the option for one unit, and it changes every second the market is open.
The strike price is the fixed price written into the contract, and choosing it is one of your biggest decisions. Here is a simple guide on how to pick the right strike price.
The expiry date is the last day the contract is valid, after which it settles and stops trading.
The lot size is the smallest quantity you can trade, set by the exchange. Check the latest Nifty lot size before every trade, because it changes from time to time.
Moneyness tells you where the strike sits compared to the current price. An option can be in the money, at the money or out of the money, and this ITM vs ATM vs OTM guide explains each one.
Open interest (OI) is the number of contracts that are still open at a strike, and traders use it to see where the crowd is placing bets.
Implied volatility (IV) is the market’s guess of how much the price may move. When IV is high, options cost more. Learn how to read implied volatility before trading around big events.
The option chain is the table that lists every strike for one expiry, with its premium, OI and IV side by side.
See all of these terms on one screen. Open the Nifty option chain and check the premium, OI and IV for any strike.
Option Buyers vs Option Sellers
Every trade has two sides. The buyer pays the premium. The seller, also called the writer, receives it.
Buyers need a strong move to make money. Sellers win more often but can take a big hit on one bad day. This guide on what option selling is and how it works covers the seller’s side in detail.

What Changes an Option’s Price?
An option’s premium has two parts. Intrinsic value is the amount the option would be worth if it expired right now. Time value is the extra amount people pay for the chance that the price moves further before expiry.
Four things push the premium up or down:
The price of the underlying moves the premium the most. Calls gain when it rises and puts gain when it falls.
Time to expiry matters because time value shrinks every day, and it shrinks fastest in the last few days.
Implied volatility raises premiums when the market expects big moves, such as before results, the Budget or an RBI policy.
Interest rates have a small effect, and most short-term index traders can ignore them.
Traders measure each of these effects with numbers called the Greeks. Start with this practical guide to option Greeks like Delta, Theta and Vega.
Options Trading in India: The Rules Right Now
Exchange rules change often. Many older guides online still show the wrong expiry days and lot sizes, so here is where things stand.
Expiry Days
Nifty 50 weekly options expire every Tuesday on the NSE, and the monthly contract expires on the last Tuesday of the month.
Sensex weekly options expire every Thursday on the BSE, and the monthly contract expires on the last Thursday of the month.
Bank Nifty, FinNifty and Nifty Midcap Select have monthly contracts only, which expire on the last Tuesday of the month.
If an expiry day is a market holiday, the contract usually expires on the trading day before it.

Lot Sizes
These lot sizes apply from the January 2026 contracts. Always confirm them on the exchange website before you trade.
Settlement
Index options are settled in cash, so no shares change hands.
Stock options are different. If a stock option is in the money at expiry, it is settled by delivery of the actual shares, which can need a lot of money. Read how to avoid taking delivery in a deep ITM stock option before you trade stock options near expiry.
How to Start Options Trading in India: 6 Steps
Open a demat and trading account with a broker and activate the F&O segment. Brokers ask for income proof before they switch it on.
Practise before you use real money. Paper trading for beginners shows how to trade options with virtual money first.
Pick one index and one expiry to learn on, such as the Nifty weekly contract, instead of jumping between many.
Read the option chain and choose a strike that matches your view and your budget.
Write down your exit before you enter: your target, your stop loss and the time you will close the trade. Use a position size calculator so one bad trade cannot hurt your account too much.
Review every trade. Note what you planned, what happened and what you will change next time.
Practise step 2 the realistic way. Replay any past market day in the Option Simulator and place trades candle by candle, as if it were live.
Beginner-Friendly Options Strategies
A strategy is a set of one or more options you combine to match a market view. Start with simple ones where the risk is known before you enter.
Each of these is explained with examples in our guide to the best option trading strategies in India. For a range-bound market, this iron condor strategy guide goes step by step.
You can also build any of them in the Strategy Builder and see the payoff chart, Greeks and margin before you trade.

Algorithmic Options Trading: Turning a Strategy Into Rules
Algorithmic options trading means writing your strategy as clear rules and letting software place the trades. A rule could be “sell the ATM straddle at 9:20 AM, keep a 25% stop loss on each leg and exit at 3:15 PM”.
Rules help options traders in a few ways:
They remove guesswork at the moment of entry, when fear and greed are strongest.
They manage several legs at once, which is hard to do by hand on a fast day.
They exit at your stop loss even if you are away from the screen.
They can be tested on years of past data before you trust them with money.

Algo trading is legal for retail traders in India. Since 1 April 2026, SEBI’s framework requires algo orders to go through your broker and carry an exchange-assigned Algo ID. This explainer on SEBI’s algo trading rules covers what that means for you.
Risks You Should Understand First
SEBI’s study of the equity derivatives segment found that about 91% of individual traders made a net loss in FY25. Together, those losses came to about ₹1.06 lakh crore. Knowing why helps you avoid the same traps.
Lot sizes multiply every rupee of premium, so a small move in the premium becomes a big move in your account.
Time decay works against buyers every single day, and fastest near expiry.
Premiums can fall sharply right after an event like results or the Budget, even if the price moves your way. Traders call this an IV crush.
Sellers can lose many times the premium they collected if the market makes a sudden big move.
Expiry day brings fast, large swings in premium. These Nifty expiry day rules help you plan for it.
Brokerage, taxes and slippage eat into profits, especially if you trade often.
Common Mistakes Beginners Make
Many beginners buy far out-of-the-money options because they look cheap, but most of these expire worthless.
Some traders enter without an exit plan and then hold losing trades hoping they will come back.
Adding more lots to a losing position turns a small loss into a large one.
Trading too many lots too early leaves no room to learn from mistakes.

How Options Trading Profits Are Taxed
In India, profits and losses from F&O trading are usually treated as non-speculative business income, not capital gains. They are added to your income and taxed at your slab rate. Most F&O traders file ITR-3, and a tax professional can tell you if an audit applies to you.
From Your First Call Option to a Tested Plan
Options reward preparation more than prediction. Pick one index, then write down when you enter, which strike you choose, where you exit and how much you risk on each trade. Check how those rules behaved over past expiries and in today’s market before real money goes in.
AlgoTest puts the option chain, simulator and backtesting in one place, so you can see how an idea behaves before you decide to trade it.

FAQs
Is options trading good for beginners?
It can be, if you start small and learn first. Buying options limits your loss to the premium, which makes it easier to control risk. Practise with paper trading or a simulator before you use real money.
How much money do I need to start options trading in India?
To buy one option, you need the premium multiplied by the lot size. For a Nifty option, that is the premium times 65. Selling options needs much more, because the broker blocks margin, so check the amount with a margin calculator first.
Can you lose more than you invest in options?
An option buyer cannot lose more than the premium paid. An option seller can, because losses grow as the price moves further against the position. This is why sellers use stop losses or hedges.
What do CE and PE mean in options?
CE means a call option and PE means a put option. The “E” stands for European, which means the option can only be exercised at expiry. You can still buy or sell it any time before that.
What is the difference between options and futures?
A futures contract makes both sides buy or sell at the agreed price, so gains and losses can be large on both sides. An option buyer has a right but no duty, so their loss is limited to the premium. Learn more about futures and options algo trading in India.
Is algo trading in options allowed in India?
Yes. Retail traders can use algos as long as the orders go through a broker under SEBI’s algo trading framework. Each algo order now carries an exchange-assigned Algo ID.
