Common Options
Mistakes to Avoid
Most options losses come from a short list of repeatable errors — not bad luck. Knowing these mistakes before you make them is one of the highest-ROI lessons in derivatives trading.
Mistake 1: Ignoring time decay when buying options
Theta is the daily cost of holding an option. For buyers, it is a constant drag — even on flat days. Far out-of-the-money options that are close to expiry lose value fastest. A trader who buys a NIFTY OTM call on Tuesday hoping for a move by Thursday often finds that even a 100-point rally does not make the trade profitable because theta has eaten into the premium.
The fix: if you are buying options, buy with enough time for your thesis to play out — at least 5 to 10 trading days is a common rule of thumb, though no fixed number suits every situation. Understand how to read the option Greeks before sizing a position.
Mistake 2: Buying deep out-of-the-money options for cheap premium
Deep OTM options are inexpensive for a reason — the probability of them expiring in the money is very low. Many beginners are attracted to the idea of buying a ₹5 option and watching it become ₹500 on a massive move. In reality, those options expire worthless the vast majority of the time. The expected value of consistently buying cheap OTM options is negative for most underlying instruments.
A more considered approach is to buy options closer to the money, where delta is higher and the position actually responds meaningfully to underlying movement. For a comparison of how different strike choices behave, see ITM, ATM and OTM explained.
Mistake 3: Holding through expiry hoping for a reversal
Experienced traders cut losses; beginners hold and hope. An option that has lost most of its value three days before expiry is very unlikely to recover — the math of theta and probability is against it. Yet traders hold, paralysed by the sunk-cost fallacy, until the position expires worthless.
Set a maximum loss rule before entering: for example, if the option loses 40–50% of its value, exit and redeploy capital. Defining the exit upfront removes the emotional decision in the heat of the trade.
Mistake 4: Over-leveraging — too many lots for the account size
Options are leveraged instruments, and the margin required for one NIFTY lot is a fraction of the notional exposure. This tempts traders to take on far more exposure than their account can absorb. One gap-down opening on a short-seller position can trigger a margin call before the trader even has a chance to react.
A worked example: suppose NIFTY is near 22,500 and a trader sells two lots of the 22,300 put for ₹90 each, collecting ₹13,500 total. A global sell-off drives NIFTY down to 22,100 overnight. The put jumps to ₹300. Mark-to-market loss: (300 − 90) × 75 × 2 = ₹31,500 — more than double the premium collected, on a 200-point move. Good position sizing would have limited the lot count so this loss was survivable.
Mistake 5: Trading around events without accounting for IV crush
Before major events — budget, RBI policy, quarterly results — implied volatility rises as the market prices in uncertainty. After the event, IV collapses, often sharply, even if the underlying moves in the expected direction. This phenomenon is called IV crush.
A buyer who correctly predicts the direction but buys at high IV can still lose money if the vega loss from collapsing IV outweighs the delta gain from the move. Before entering pre-event trades, check IV rank and IV percentile to understand whether options are already expensive relative to their own history.
Mistake 6: Ignoring liquidity — wide bid-ask spreads
Not all options contracts trade freely. Far-OTM strikes and longer-dated contracts in stock options often have very wide bid-ask spreads. Entering such a contract means you are already losing money the moment you are filled, because the spread itself is a cost. Check open interest and volume before placing any trade — a contract with fewer than a few hundred lots of OI is usually too illiquid to trade safely.
Mistake 7: Conflating being right on direction with making money
You can correctly predict that NIFTY will rise by 200 points and still lose money on a call option — if the move happens too slowly (theta), the IV collapses (vega), or you bought the wrong strike (insufficient delta). Options are multi-dimensional instruments. Before entering, it helps to ask: what does this option need — in terms of price, time, and IV — for me to make money? Tools like the Greeks dashboard at /option-greeks can help model these scenarios.
Mistake 8: Not having a plan for what you will do if wrong
Perhaps the most common mistake across all trading is not deciding in advance what you will do when the trade goes against you. Without a pre-defined stop or adjustment rule, every losing trade becomes a real-time emotional decision — and those decisions are almost always made poorly. Before entering, write down: my maximum loss is ₹X. If the position reaches that level, I will [exit / adjust / roll]. For adjustment strategies, see adjusting positions and when to roll an options position.
Frequently asked questions
Why do most options buyers lose money?
Most option buyers lose because time decay (theta) works against them constantly. Even if the underlying moves in the right direction, a slow move or a drop in implied volatility can prevent the option from gaining value. Buying far-OTM options with little time remaining amplifies this problem.
What is over-leveraging in options?
Over-leveraging means allocating too large a portion of your capital to a single options position. Because options can lose 50–100% of their value quickly, a single bad trade can wipe a significant fraction of the account. The fix is strict position sizing — never risking more than a small percentage of total capital per trade.
Is buying options safer than selling?
Buying options does have defined risk — you can only lose the premium paid. However, the probability of profit is lower, and time decay works against you. Selling has higher win rates but larger potential losses. Neither is inherently safer; the right choice depends on your view, risk tolerance, and the market environment.
How do I avoid getting stuck in an illiquid options contract?
Always check the bid-ask spread and open interest before entering a trade. Contracts with very low open interest or wide spreads are illiquid — you may not be able to exit at a fair price. Stick to near-ATM strikes on weekly NIFTY or Bank Nifty expiries for the best liquidity.
