Option Trading

What Is an Option?
An option is a financial contract that gives the buyer the right, but not the obligation, to buy or sell an underlying asset at a specific price (called the strike price) on or before a specific date (called the expiry date).

There are two main types of options:

Call Option – Gives the right to BUY the underlying asset.

Put Option – Gives the right to SELL the underlying asset.

🔹 Example:
If you buy a Call Option on Reliance with a strike price of ₹2,500 and the stock goes to ₹2,600, you can buy it at ₹2,500 and sell it at market for ₹2,600 – making a profit.

Basic Terminologies in Option Trading
Strike Price: The fixed price at which the option holder can buy or sell the asset.

Premium: The price paid to buy the option contract.

Expiry Date: The last date on which the option can be exercised.

Lot Size: The fixed quantity of the underlying asset in one options contract.

ITM/ATM/OTM (Moneyness):

In the Money (ITM): Option has intrinsic value.

At the Money (ATM): Strike price = current market price.

Out of the Money (OTM): Option has no intrinsic value yet.

Core Concepts of Option Trading
1. Option Buying vs Option Selling
Option Buyers pay a premium and have limited risk but unlimited profit potential.

Option Sellers (Writers) receive the premium but take on potentially higher risk.

2. Time Decay (Theta)
Options lose value as they approach expiry. This is called time decay. It works against buyers and in favor of sellers. Therefore, option sellers benefit more from time decay.

3. Volatility (Vega)
Volatility affects the premium of options. Higher expected volatility leads to higher premiums. Traders often use Implied Volatility (IV) and Historical Volatility (HV) to make trading decisions.

4. Option Greeks
Advanced traders use Greeks to measure different risks in an option:

Delta: Sensitivity to price change.

Gamma: Change in Delta with price movement.

Theta: Impact of time decay.

Vega: Impact of volatility changes.

Rho: Impact of interest rate changes.

Understanding Greeks is crucial for adjusting and managing option positions.

Popular Option Strategies
Once a trader understands calls and puts, they can use strategies combining multiple options:

✅ Single-Leg Strategies (Basic)
Buying Call or Put: Speculative strategy to profit from movement in one direction.

Selling Call or Put: Used to earn premium with a view that the market will stay flat or move in the opposite direction.

✅ Multi-Leg Strategies (Advanced)
Bull Call Spread: Buy one call and sell another at a higher strike. Used in moderately bullish outlook.

Bear Put Spread: Buy one put and sell another at a lower strike. Used in moderately bearish outlook.

Straddle: Buy a call and a put at the same strike and expiry. Used when expecting a big move, but unsure of the direction.

Iron Condor: Four-option strategy used in sideways markets to earn limited profits with limited risk.

Risk Management in Option Trading
Because options involve leverage, managing risk is crucial. Key practices include:

Position sizing: Only use a small portion of capital per trade.

Stop-loss and Target levels: Always have a predefined exit plan.

Avoid overtrading: Overuse of leverage leads to quick losses.

Understand margin requirements: Especially important for sellers.

Tools Used in Option Trading
Traders use various tools to analyze the market:

Option Chain Analysis: Shows available strike prices, premiums, and Open Interest (OI).

OI Data: High OI at certain strikes indicates strong support/resistance.

IV Chart: Helps spot overbought or oversold options.

Payoff Diagrams: Visual representation of potential profit or loss.
