What's the Biggest Mistake New F&O Traders Make?
SEBI data says 93% of Indian F&O traders lose money over three years. The biggest single mistake — buying far OTM weekly options with no plan — shows up in every trader's journey. Here is what the data actually says, the five errors that feed that one mistake, and the practical fixes that keep your capital alive.
The single biggest mistake new F&O traders make is buying far out-of-the-money weekly options with no stop-loss, no target, and no understanding of how quickly theta destroys the position. SEBI data shows 93% of individual F&O traders lost money over three years (FY22–FY24), and the average loss per person was ₹2 lakh. The fix is not complicated — trade less often, size smaller, use stop losses, and stop chasing lotteries. But the fix requires discipline, which is exactly what the market is designed to exploit.
The numbers behind retail F&O trading in India:

only 7.2% over 3 years
SEBI just published the numbers. They are brutal.
In August 2025, SEBI released a comprehensive study of individual traders in the equity derivatives market covering FY22 to FY24. The headline: 93% of individual traders — 1.05 crore out of 1.13 crore unique traders — lost money in F&O over the three-year period. Combined net losses: ₹1.81 lakh crore. For the traders who did lose, the average loss was ₹2 lakh per person. For the 7.2% who made money, the average profit was ₹3 lakh — meaning the winners made more than the losers lost, but there were just far fewer of them.
The picture got worse in FY25. According to NSE data cited by the Economic Times and Business Standard, retail traders suffered net losses of ₹1,05,603 crore in FY25 — a 41% increase from FY24's ₹74,812 crore. SEBI's December 2025 update confirmed 91% of individual traders lost money in FY25. And Zerodha CEO Nithin Kamath told ET Now that roughly 16% of active retail traders lost their entire trading capital in FY25.
The one mistake underneath all five mistakes
Every trader loses money sometimes. Professional traders lose on 40–50% of their trades and still end up profitable because they manage size, risk, and exits. The difference between a professional and a losing trader is not win rate — it is how they behave when they lose. New F&O traders lose money not because options are inherently dangerous, but because they approach options with the wrong mental model: they treat lottery tickets as investments.
The core error: buying far OTM weekly options hoping for a big payoff. This is not trading — it is gambling with a brokerage account. SEBI's own data confirms that individual traders are overwhelmingly net buyers of short-dated OTM options. The institutional side (market makers and HFT firms) are the sellers, and they have every statistical advantage.
The five specific errors that kill new accounts
Error 1: Buying far OTM weekly options
A Nifty call option that is 3–5% out of the money, expiring in 2–3 days, costs ₹10–30. It feels cheap. It is not cheap — it is a probabilistic trap. The probability of that option finishing in the money is usually below 10%. The expected value of the trade, after accounting for theta decay and transaction costs, is negative. You are paying ₹15 for a ₹100 chance. That is a -EV bet, and over hundreds of trades, -EV bets produce guaranteed losses.
- SEBI data shows individual traders are overwhelmingly net buyers of short-dated options — the exact positions that decay fastest
- Weekly options lose 5–15% of their value per day in the final week before expiry (theta acceleration)
- The "lottery" payoff of 5x–20x is real, but it happens maybe 5–10% of the time — the other 90% of trades are slow bleeds
The fix: stop buying far OTM weeklies as your default trade. If you want to buy options, use at-the-money or slight OTM strikes with 15–30+ days to expiry. Yes, they cost more. But they give you time and delta, which are the two things a buyer actually needs.
Error 2: No stop-loss, no target
This one is so obvious it almost does not need stating, yet it is the single most common behaviour pattern among losing traders. A Reddit post on r/IndianStreetBets from a 28-year-old software engineer described it perfectly: he started with ₹50,000, lost ₹6.5 lakh in one year, and kept doubling down to recover losses. He eventually accumulated ₹1.25 crore in debt. The pattern is always the same — no stop-loss, no predefined risk, just hope.
A stop-loss is not optional for an option buyer. Options are wasting assets. Unlike stocks, which can hold value indefinitely, every option has an expiry date. If the underlying does not move in your favour before expiry, the option goes to zero — and without a stop-loss, you ride it all the way down. Professional traders typically risk 1–2% of capital per trade. New traders routinely risk 20–50% on a single option position.
Practical stop-loss rules for option buyers:
- Set a maximum loss of 20–30% of the premium paid — exit when it hits
- Set a target of 50–100% profit — book partial profits and let the rest ride with a trailing stop
- Never add to a losing position to "average down" — the option is decaying, not recovering
- If you cannot define your stop before entering, do not enter
Error 3: Not checking VIX before entering
India VIX measures the market's expectation of 30-day volatility. When VIX is elevated (above 16–18), all option premiums are expensive. When VIX is low (below 12), premiums are cheap. New traders enter trades without checking VIX, which means they buy options when premiums are already inflated (post-event or during high fear) and then watch them collapse even if the underlying moves in their favour — a phenomenon known as IV crush.
SEBI's study noted that many retail losses cluster around events — budget days, RBI policy announcements, global crises — when VIX spikes and premiums surge. Traders buy into the excitement, pay inflated premiums, and then watch the premium collapse after the event passes, even if their directional view was correct.
Always check India VIX before entering an option trade. If VIX is above 18, you are paying a fear premium — consider selling instead of buying, or using spreads to reduce cost. If VIX is below 12, premiums are relatively cheap and option buying has better odds.
Error 4: Overtrading — the transaction cost trap
SEBI's FY24 data found that the average transaction cost per trader was ₹26,000. That is not brokerage alone — it includes STT, exchange charges, GST, SEBI turnover fees, and stamp duty. For traders making 10–20 trades a day, transaction costs alone can eat 3–5% of capital per month, even if every trade is break-even before costs. You do not need to lose money on your trades to lose money overall — the friction alone is enough.
Overtrading also degrades decision quality. A study of 43 lakh futures trades found that trading profitability declines as frequency increases. Traders who made 500 or more trades per year had an 80% loss rate. The more you trade, the more you are paying the house edge, and the more likely you are to make emotional decisions after a string of losses.
Signs you are overtrading:
- You enter 3+ option trades a day
- You cannot explain why you entered a specific trade
- You feel anxious when you are not in a position
- You trade to recover from a previous loss (revenge trading)
- Your transaction costs exceed your profits
Error 5: Ignoring position sizing
Position sizing is not a glamorous topic. It does not get views on social media. But it is the single most important factor in whether a trader survives long enough to become profitable. A professional trader risks ₹5,000–₹10,000 per trade on a ₹5 lakh account. A new trader puts ₹50,000–₹1,00,000 into a single option trade on the same account. The professional can lose 10 trades in a row and still have 90% of capital. The new trader is blown up after 3 losses.
SEBI's data tells the story: the top 3.5% of loss-makers — the biggest losers — had an average loss of ₹28 lakh per person. That does not happen from a few bad trades. That happens from consistently taking oversized positions and refusing to cut losses. Meanwhile, the traders who were profitable had an average profit of ₹3 lakh over three years — modest, but real. The difference is not skill. It is sizing.
The 1% rule: never risk more than 1–2% of your trading capital on a single trade. On a ₹2 lakh account, that means your maximum loss per trade should be ₹2,000–₹4,000. If that feels too small to matter, it is exactly right — small losses let you survive long enough to learn.

The real-world cost: a case study
Nitin Kamath, CEO of Zerodha, shared a specific example on Instagram in May 2025: a professional with a ₹50 lakh annual salary lost over ₹2 crore in F&O trading. That is not a typo — a person earning ₹50 lakh a year (top 1–2% of Indian earners) blew up four years of pre-tax salary in the derivatives market. The loss was not from a single trade. It was from months of escalating position sizes, revenge trading, and refusing to accept that the strategy was not working.
This is not an unusual case. The pattern shows up across every broker's data: a trader starts small, loses, increases size to recover, loses bigger, takes a "sure thing" trade to recover everything, and blows up. The emotional spiral is predictable. The fix is mechanical — predefine risk, predefine exits, and follow them regardless of how you feel.
The post-SEBI-curb picture
SEBI tightened F&O regulations in late 2024 — increasing lot sizes, reducing the number of weekly expiries, and raising margin requirements. The impact was immediate. In Q4 FY25, the number of active individual F&O traders dropped from 53.5 lakh to 42.7 lakh. But average losses per trader narrowed: from ₹66,880 in Q3 to ₹57,920 in Q4, and net losses fell from ₹33,661 crore to ₹24,745 crore. Fewer traders, smaller losses per person — the regulations pushed the worst-positioned traders out.
The lesson from the curbs is simple: the problem was never that F&O trading is inherently bad. The problem was that F&O allowed new traders to take positions that were way too large relative to their capital, too frequently, with too little understanding. Reducing access to the most dangerous instruments (short-dated, far OTM weeklies) actually improved outcomes for the remaining participants.
A practical framework to avoid these mistakes
Before entering any F&O trade, answer these five questions:
- What is my maximum loss on this trade? (If it is more than 2% of capital, reduce size)
- What is my target? (If you cannot define a target, you are gambling)
- What is India VIX right now? (Above 18 = expensive premiums, consider selling)
- Have I taken more than 2 trades today? (If yes, stop)
- Am I trading to recover a loss? (If yes, close the app)

The bottom line
The biggest mistake new F&O traders make is not a single trade — it is a pattern of behaviour. Buying far OTM weeklies, ignoring stop losses, not checking VIX, overtrading, and taking positions that are too large for their capital. These five errors are all connected: they all come from treating options as lottery tickets instead of as tools that require precision, discipline, and risk management.
SEBI's data is clear: 93% of F&O traders lose money over three years. But that number also means 7% are profitable. The profitable ones are not smarter — they are more disciplined. They size small, cut losses fast, trade less often, and respect the math of options. That is a learnable skill. The hard part is not knowing what to do. The hard part is doing it when you are staring at a losing position at 2:45 PM on expiry day.
- SEBI data: 93% of individual F&O traders lost money over FY22–24, with combined losses of ₹1.81 lakh crore and average loss of ₹2 lakh per person.
- The biggest single mistake is buying far OTM weekly options without stop-losses — SEBI confirms individual traders are overwhelmingly net buyers of short-dated options.
- Overtrading is a silent killer: traders with 500+ trades per year had an 80% loss rate, and average transaction costs reached ₹26,000 per trader in FY24.
- The fix is mechanical, not emotional: never risk more than 1–2% per trade, always set stop-losses before entering, check VIX, and stop after 2 trades per day.
- Post-SEBI curbs improved outcomes: active traders fell from 53.5L to 42.7L, and average losses per trader narrowed, proving that reducing access to the riskiest instruments helps.
Frequently Asked Questions
What is the biggest mistake new F&O traders make?
Buying far out-of-the-money weekly options with no stop-loss, no target, and no understanding of theta decay. SEBI data shows individual traders are overwhelmingly net buyers of short-dated OTM options, and these positions have a negative expected value because of how quickly time decay erodes them.
What percentage of F&O traders lose money in India?
According to SEBI's comprehensive study covering FY22 to FY24, 93% of individual traders (1.05 crore out of 1.13 crore) lost money in equity F&O. In FY25, 91% of individual traders lost money, with net losses of ₹1,05,603 crore — a 41% increase from the previous year.
How much money do retail traders lose in F&O?
Over FY22–24, retail F&O traders lost a combined ₹1.81 lakh crore. The average loss for loss-makers was ₹2 lakh per person. In FY25 alone, net losses reached ₹1,05,603 crore. Zerodha CEO Nithin Kamath noted that approximately 16% of active retail traders lost their entire trading capital in FY25.
How can new traders avoid F&O losses?
Follow these rules: never risk more than 1–2% of capital per trade, always set a stop-loss before entering, check India VIX before buying options (high VIX = expensive premiums), limit yourself to 2 or fewer trades per day, and avoid far OTM weekly options as your default strategy. Use defined-risk strategies like spreads instead of naked option buying.
Did SEBI ban F&O trading?
SEBI did not ban F&O trading, but in late 2024 it tightened regulations: increasing lot sizes, reducing the number of weekly expiry days, and raising margin requirements. The goal was to reduce speculative overtrading. The impact was positive — active traders dropped from 53.5 lakh to 42.7 lakh, and average losses per trader narrowed.
Why do most option buyers lose money?
Option buyers lose money because options are wasting assets — they lose value every day due to theta decay. Buying far OTM options compounds this problem because those options have low delta (they need a big move to become profitable) and high time decay relative to their premium. Over 90% of far OTM weekly options expire worthless.
