Common Mistakes in Option Trading Strategies

The mistakes that cost options traders money are remarkably consistent, and almost none of them involve getting the direction wrong. They involve the instrument being misunderstood in ways that produce losses on trades where the analysis was sound.

Each of the following has a specific remedy. Recognising which one applies to your own record is more useful than adopting a new strategy, because the same mistake will follow you into it.

Buying the Cheapest Strike Available

Distant strikes cost little because they are unlikely to become valuable. Traders read low cost as low risk and buy the component most certain to decay to nothing.

The remedy is selecting the strike from the expected size of the move — one that becomes meaningfully valuable if that move occurs, rather than requiring twice as much.

Treating Direction as the Whole Analysis

Premium responds to direction, the size of the move, the time taken and changes in volatility expectations. A view stating only direction provides no basis for choosing a contract.

The remedy is a complete view: direction, expected magnitude and timeframe, written before selecting anything, as described in options intraday tips.

Ignoring Time Decay Until It Bites

Time value erodes continuously and accelerates near expiry. Being directionally right but slow produces a loss while the underlying does exactly what was predicted.

The remedy is matching expiry to the timeframe the view assumes, and adding a time-based exit so a position that has not worked within its window is closed rather than held in hope.

Buying Premium Into Scheduled Events

Volatility expectations are elevated before announcements and collapse once uncertainty resolves. A position bought then frequently loses even when the event produces a large move.

The remedy is being flat into scheduled events, or accepting that such a position needs a far larger move than the direction alone suggests.

Oversizing Because the Loss Is Defined

For buyers the maximum loss is the premium, which looks small against the account and invites a larger position than the risk framework permits.

The remedy is capping premium committed as a fixed fraction of capital per session rather than per trade. A run of small defined losses is how accounts erode without any single trade breaching its limit.

Rounding Up to the Nearest Lot

Contracts trade in fixed lots, so correct sizing sometimes calls for less than one. Taking the trade anyway abandons the risk framework at the moment it was doing its job.

The remedy is simple and unpopular: where proper sizing falls below one lot, take no position.

Trading Strikes With No Depth

Liquidity concentrates near the current price in the nearest expiry. Outside that, spreads widen sharply, and on a low-priced contract the spread is a large percentage of the premium.

The remedy is checking spread and depth at the exact contract before entry rather than relying on the underlying’s volume. An illiquid strike is easy to enter and expensive to leave.

Ignoring the Round-Trip Cost

Option spreads are proportionally wide and are paid on entry and again on exit. At frequency this single cost can exceed brokerage and levies combined.

The remedy is computing the full round-trip figure at your usual size and requiring every setup to clear it comfortably before the trade is considered.

Selling Options Because Most Expire Worthless

Selling collects premium and benefits from decay, which makes it appear reliable. The risk shape is inverted: many small gains punctuated by occasional large losses, with obligations exceeding the premium received.

The remedy is treating sold positions as requiring margin, continuous attention and strict position limits rather than confidence in the frequency of small wins.

Letting a Defined-Risk Position Become Open-Ended

Multi-leg structures invite improvisation as the underlying moves. Closing one leg or adding another can convert a capped-risk position into an uncapped one.

The remedy is deciding permitted adjustments before entry, and treating anything outside that list as a reason to close rather than to modify.

Rolling to Avoid Recognising a Loss

Moving a position to a later expiry or different strike is presented as management. It is a fresh trade with fresh costs, and it is frequently taken to postpone an admission.

The remedy is a single test: would you open the new position from scratch today? If not, rolling into it is not management.

Widening the Stop

Moving a stop away from price converts a planned small loss into an unplanned large one, and it is always justified in the moment by a reason that seems sound.

The remedy is resting orders, since an intention to exit requires you to act correctly at exactly the point judgement is least reliable.

Increasing Size to Recover

Raising quantity after a loss applies the largest position when judgement is most impaired. Because premium moves sharply, the recovery attempt frequently exceeds the original loss.

The remedy is a daily limit set before the session and acted on automatically, plus a rule to reduce size rather than raise it after consecutive losses.

Building Complexity Without a View

Multi-leg structures feel professional, and that feeling is not evidence. A complicated position with no specific expectation behind it is several ways to pay transaction costs at once.

The remedy is working from the view outward: direction, magnitude, timeframe, then the simplest structure that expresses it.

Stacking Correlated Positions

Two positions in the same direction on correlated underlyings, or an index position alongside its heavyweight constituents, express substantially the same view at multiplied size.

The remedy is assessing total directional exposure rather than counting positions, as set out in index intraday tips.

Reading Percentage Returns on Premium

A small absolute change is a large percentage change when premium is low. Those figures read as evidence of a powerful method and encourage sizing up.

The remedy is judging results against capital committed rather than against premium, since the same arithmetic applies in reverse.

Holding to Expiry Without Knowing the Mechanics

Positions held to expiry are settled rather than disappearing, and a seller can face an obligation requiring funds or margin.

The remedy is establishing the settlement mechanics of the specific contract before the final sessions, and deciding in advance whether to close or carry.

Not Keeping a Record That Permits Diagnosis

Without the view, the expected move, the contract chosen, the premium and the spread at entry, every loss looks like an analytical failure and the wrong thing gets changed.

The remedy is logging those fields from the first trade, then reviewing them together, as covered in evaluating trading strategies and the routine in the intraday trading guide.

Carrying Sizing Between Instruments

A concentrated sector index travels considerably further in a session than a broad benchmark, and single stocks can gap on their own news. The same quantity carries very different risk across them.

The remedy is deriving size from each instrument’s own recent range rather than applying one habitual number, as set out in Bank Nifty intraday tips.

Using Options for a Simple Directional View

Where the view is purely directional and short-horizon, options add decay and volatility effects that have nothing to do with the analysis. Being right can still lose.

The remedy is choosing the instrument from the view: linear exposure for directional views, as covered in futures intraday tips, and options only where the payoff structure itself is wanted.

Trading Every Session Regardless of Conditions

Some sessions offer narrow range, thin participation and no clean structure. Costs in those conditions are certain while edge is not.

The remedy is treating standing aside as an active decision with positive expected value, rather than as a missed opportunity. Requiring a position daily turns a selective method into an indiscriminate one.

FAQs

Why are cheap strikes a mistake?

They are cheap because they are unlikely to become valuable. Low cost reads as low risk while actually buying the component most certain to decay away.

How does a defined loss lead to oversizing?

The maximum loss looks small against the account, so positions get larger than the framework permits. A run of small defined losses erodes capital without any single breach.

Is rolling a position ever correct?

Only if you would open the new position from scratch today. Rolling to postpone recognising a loss is a fresh trade disguised as management.

Why is selling options riskier than it appears?

The risk shape is inverted — many small gains and occasional large losses, with obligations exceeding the premium received. It requires margin and strict limits.

What is wrong with judging returns on premium?

Percentage moves on a small premium describe the instrument’s sensitivity, not decision quality, and the same arithmetic applies in reverse.

How should losing runs be handled?

Reduce size and continue at the reduced level. Increasing size to recover applies the largest position when judgement is most impaired.

What record makes diagnosis possible?

The view, expected move, timeframe, contract, premium, spread at entry and whether the plan was followed. Without those, the wrong cause gets blamed.
