Common Mistakes in Options Trading – Option Buying Errors, Option Selling Mistakes, Expiry Day Traps, Volatility Traps & Risk Management

Mistakes in Options Trading

In Part 7 we discussed how AI‑powered LTP Calculators analyze option premiums, implied volatility, Open Interest and Option Greeks to assist options traders. We also highlighted benefits and limitations of AI in options trading.

In this part our attention will turn to the other side of the table. As great as LTP Calculator is it cannot stop losses if traders keep committing avoidable errors. Knowing and avoiding these pitfalls often determines if traders are consistent or not over time.

Most Common Reasons Why Options Traders Lose Money

Contrary to popular belief it’s not lack of indicators or tools that account for most of the losses. Traders often lose money due to factors like:

• Poor Risk management by traders
• Emotional decision‑making by traders
• Misunderstanding option pricing by traders
• Ignoring volatility by traders
• Trading without a plan by traders
• Misinterpreting the NSE Option Chain by traders
• Misusing an LTP Calculator by traders

Successful options trading is about discipline and not about chasing a “perfect” indicator.

Mistakes in Options Trading #1: Buy Options only because they are Cheaper

This is one of the most common beginner mistakes. Traders tend to assume that ₹15 premium is better than ₹150 premium. This is almost always wrong.

Example

Current Nifty: 25,000

The ₹18 option appears cheap but:

• Has low Delta
• High probability of expiring worthless
• Rapid Theta decay
• Require a large market move

The ₹160 option may actually offer a higher probability of winning.

Professional Approach: Instead of buying cheaper options compare Delta, OI, IV, Time Value, Liquidity and Probability. This is where an LTP Calculator option chain becomes helpful.

Mistakes in Options Trading #2: Ignore Open Interest

Premium never tells the whole story. Professional traders always study Open Interest.

Example

Despite having a higher premium the first contract has significantly higher participation. Higher OI means:

• Better liquidity
• Smaller spreads
• Execution
• Stronger market participation

Ignoring OI often results in poor trade selection.

Mistakes in Options Trading #3: Ignore Change in Open Interest

Many traders look at OI as a snapshot. Professional traders analyze change in OI for deeper insights.

Example

This helps identify whether new positions are being opened or existing ones are being closed.

Mistake #4: Ignore Implied Volatility

Many beginners buy options before big events. Examples: RBI Policy, Union Budget, Company Earnings, US Federal Reserve announcements. These events often cause a spike in IV. Higher IV means premiums. After the event IV usually crushes down. Even with a move in the market option premiums may not rise much due to IV Crush.

Example

Before Event

Premium: ₹220

IV: 32%

After Event

Premium: ₹180

IV: 18%

Even though Nifty remained near the level Premium declined as IV expectations fell.

Mistakes in Options Trading #5: Ignore Theta Decay

Time is one of the enemies of option buyers. As each day passes the time value gets eroded. Theta decay is accelerated during weekly expiry.

Example:

Wednesday Premium: ₹140

ThursdayPremium: ₹125

Friday Premium: ₹102

Monday Premium: ₹48

Tuesday (Expiry) Premium: ₹6

without a significant move in the underlying index time decay can destroy option value.

An LTP Calculator helps traders notice this decay across expiries.

Mistake #6: Buy Far Out-of-the-Money Options

Many traders purchase OTM options because they are cheap.

Example

Current Nifty : 25,000

Trader buys : 25,600 CE

Premium : ₹5

Expectation : Rally…

Reality : The option expires worthless unless the market makes a huge move.

Professional traders realize that cheap options premium often come with low probability.

Mistake #7: Trade Without a Stop-Loss

Many traders take a trade with a profit target. No exit plan.

This exposes traders to emotional decision making.

Example

Entry : ₹120

Loss reaches : ₹95

Trader thinks : “It will recover.”

Premium falls to : ₹40

Eventually : ₹8

Having a predefined stop-loss helps preserve trading capital.

Mistake #8: Overtrade

Another common mistake is making too many trades.

Reasons:

• Boredom
• Revenge trading
• Fear of missing out (FOMO)
• Overconfidence after a trade

Professional traders often make higher-quality trades based on clear criteria.

Mistake #9: Trade During Low Liquidity

Not all option contracts are liquid.

Example

Low liquidity leads to:

• Bid-Ask Spreads
• Poor execution
• Higher slippage

Before entering a trade always check:

• Volume
• OI
• Bid-Ask Spread

Mistake #10: Ignore the Market Trend

Suppose:

Daily chart: Strong downtrend.

Trader buys: ATM Call.

Because: 5-minute chart shows a breakout.

This creates a conflict between lower timeframes.

Professional traders usually trade with the trend unless they have a well-defined counter-trend strategy.

Common Option Buying Errors

Option buyers typically make these errors:

Buying Without Confirmation

Entering before:

• Breakout confirmation
• Volume confirmation
• OI confirmation

Chasing Momentum

Option buyers often buy after the premium has surged.

Example

Premium: ₹80

Trader buys: ₹180

Market pauses: Premium falls.

Ignoring Time Decay: Option buyers purchase expiry options late in the week and ignore the rapid Theta decay near expiry.

Overleveraging:Option buyers buy multiple lots just because the premiums look cheap.

Common Option Selling Errors

Option selling has kinds of risks and typical mistakes include:

Selling Naked Options

1. Unlimited risk
2. Option sellers should only sell options if they are experienced and have proper risk controls

Ignoring Volatility Expansion

1. Option sellers sell options before events
2. Unexpected increase in IV can harm option positions

No Hedging

Professional option sellers often hedge.

Examples:

• Long options
• Spread strategies

Hedging helps option sellers define and manage risk.

Holding Until Expiry Without Monitoring

1. Market conditions change close to expiry.
2. Option sellers must monitor regularly.

Expiry Day Mistakes

Expiry day attracts traders as premiums can swing. But with premium Swing risks will also rise.

Common mistakes:

• Trading without a plan
• Buying options late
• Ignoring Theta decay
• Ignoring IV changes
• Holding losing trades hoping for a reversal
• Overtrading due to premium movement

Volatility Traps

Volatility can create opportunities but also confusion.

Trap 1: Option buyers buy after implied volatility has spiked, and buy high premium.

Trap 2: Option buyers ignore volatility crush. Premium collapses after a scheduled event.

Trap 3: Option buyers compare premiums without looking at implied volatility. A higher premium doesn’t always indicate direction; it could indicate higher expected volatility.

Risk Management Principles

Every professional trader follows a risk management framework.

Risk a small percentage, per trade.

Many experienced traders limit risk to a portion of their trading capital on any position. The percentage depends on risk tolerance and trading style.

Maintain a Risk-Reward Ratio

Example

Risk: ₹100

Target: ₹200

Risk-Reward: 1:2

Over a series of trades favorable risk-reward relationships can enhance long-term expectancy if the strategy has an edge.

Position Sizing

Instead of asking: “How much can I make?”  Ask: “How much can I lose if I’m wrong?”

Position size should be determined by risk rather than emotion.

Diversification

Avoid putting all capital into a single option position. Diversifying across strategies and reducing position concentration can manage portfolio risk.

Professional Trading Checklist

Before entering any option trade check:

✅ Market trend

✅ Support and resistance

✅ Open Interest

✅ Change in OI

✅ Volume

✅ Implied Volatility

✅ Option Greeks

✅ LTP comparison

✅ Bid-Ask spread

✅ Risk-Reward ratio

✅ Stop-loss

If several of these factors are unclear it’s better to wait than force a trade.
