7 ESSENTIAL RULES OF FUTURES & OPTIONS TRADING

A complex instrument like F&O demands preparation. Before you step in, get familiar with the key concepts that can help you analyse the market.

Here’s a simple breakdown of what every beginner must know before placing their first trade:

1. Leverage can be a double-edged sword

F&O allows you to take large positions with a smaller upfront margin. This is called leverage

Why it matters:

• Both profits and losses are amplified
• Even small market moves can have a big impact
• Margin mismanagement can wipe out capital quickly

Tip: Always know your position size, margin requirements and possible loss before entering a trade.

2. Always account for Implied Volatility

Implied volatility reflects the markets expectations of future price movement and plays a major role in option pricing. Higher IV means higher option premiums, lower IV makes options cheaper.

Why it matters:

• Option premiums increase when IV rises
• Sudden drop in IV can lead to losses even if market moves in your favour
• Expiry days and major events often cause sharp changes in IV 

Tip: As a beginner, avoid buying options when Implied Volatility is extremely high. Focus on understanding how IV impacts option prices before taking larger positions.

3. Risk Management is not optional

This is a critical component that protects your capital in the long run. Risk management in F&O goes beyond just placing a stop loss, it also about knowing when to walk away even if the trade is in your favour.

Checklist to follow:

• Pre-defined stop loss- Set a strict stop-loss for each trade
• Position sizing - Deploy capital based on your risk appetite
• Realistic View- Avoid unrealistic expectation from a single trade – stick to your target

Tip: Profit comes later. Protecting capital comes first.

4. Always calculate your Risk-Reward Ratio

Before entering any trade, understand the potential reward against the risk you are taking

Why it matters:

A good risk-reward ratio (like 1:2/1:3) means you don’t have to win every trade

For example:
Let’s say you entered a trade with a risk-reward ratio 1:2,
Risk - ₹1000 
Potential profit -₹2000

That means, even if only 4 out of 10 trades work in your favour, you can still be profitable overall.

Tip: Enter a trade only after knowing your potential profit/loss.

5.  Expiry & Time Decay affect the value of your option contracts

Options lose value as they get closer to the expiration date, this is called time decay (Theta).

Why it matters:

• Option buyers lose value daily
• Option sellers generally benefit from time decay
• Prices moves accelerate closer to the expiry

Tip: Always be aware of the contract expiry before entering a position.

6. Understand ITM, ATM & OTM (Options) before placing your trade

The value of an Option depends on how close its strike price is to the current market price of the stock or index. In simple terms it explains why some options are expensive and others are cheap.

• ITM(In-the-Money)- Has intrinsic value, has relatively low risk and higher premium
• ATM (At-the-Money) – Closest to market price and is highly sensitive to price movement
• OTM (Out-the-Money)- No intrinsic value, is cheaper but riskier

7. For every winner, there’s someone who has incurred losses

Options trading is called a zero-sum game because the money made by one trade comes from another trader’s loss.

Remember:

• Profits don’t come easily or randomly
• Consistency comes from understanding risk, not from luck or tips
• Your trade against another market participant, who is often experienced

Quick Pre-Trade Checklist:

✔ Understand your position size and leverage

✔ Know the current volatility environment

✔ Enter with a predefined stop-loss

✔ Track the expiry date of your contract

✔ Start with small trades until you understand how F&O behaves

Your First Practical Exercise Before You Trade!

Before placing your first real F&O trade, try this simple exercise:

• Pick one index or stock you follow (NIFTY / BANKNIFTY, etc.)
• Note the strike price, premium, Implied Volatility, stop-loss, and target
• Calculate your risk-reward ratio before “entering” the trade
• Track how price, volatility, and time decay affect the option till market close

This helps you understand how F&O behaves without risking capital.
