Nobody opens an F&O account planning to lose it. Almost everyone who blows one up can pick a chart correctly more than half the time. Ask around, and the pattern that actually kills accounts isn't bad analysis — it's a trader who was right on direction three times in a row, got comfortable, sized up on the fourth trade, and got wrong at exactly the wrong moment. Analysis picks your entries. Risk management decides whether you're still around to use it next month.

None of the five rules below are complicated. Following them when you're three trades deep into a losing streak and convinced the next one will fix everything — that's the actual skill, and it's the one this article can't teach you by itself. Reading it is step one.

Rule 1 — Cap Any Single Trade at 2% of Capital

If your options capital is ₹5,00,000, the most you let any single trade cost you — the premium paid outright, or the defined max loss on a spread — is ₹10,000. That's the 2% rule, and it's the closest thing options trading has to a foundation.

The logic is just arithmetic, but it's arithmetic worth sitting with. Even skilled options traders lose 30-40% of their trades — that's normal, not a sign anything's broken. Cap each loss at 2% and you can lose ten in a row and still have 80% of your capital, which is a recoverable position. Lose 20% on one bad trade instead, and you now need roughly a 25% gain just to get back to even. Getting back to even from a big hole is always harder than the hole made it look going in — both mathematically and, worse, psychologically, because that's exactly when traders start taking bigger risks to catch up.

One thing worth remembering on PaperBull specifically: NIFTY trades in lots of 65 shares and SENSEX in lots of 20, so your actual position size moves in whole-lot steps, not smooth percentages. Work out your rupee risk limit first, then find the lot count that fits under it — not the other way round.

Rule 2 — Decide Your Exit Before You Enter

Every trade needs a stop loss decided in advance, while you're still calm and the position hasn't gone anywhere yet. Waiting until the trade is already down to figure out your exit means you're now making the decision with your emotions involved, which is precisely when people make the worst calls.

Illustrative example — not a recommendation

A common rule for buyers is exiting once the option has lost half its value — bought a call at ₹100, your stop sits at ₹50, and you honour it without renegotiating in your head. For sellers, a common rule is the mirror image: exit once the price you sold at roughly doubles. Sold a call for ₹40, you're out if it reaches ₹80 — you've booked a ₹40 loss instead of letting it become ₹200 or ₹300. These are illustrative starting points to adapt to your own strategy, not a specific trade recommendation.

Knowing where to stop is the easy part. Actually pulling the trigger when the price hits it — instead of telling yourself "it'll bounce" — is where most people fail, and it's exactly why building the habit with paper trading first is worth the time before real capital is on the line.

Rule 3 — Put a Ceiling on the Bad Days and Bad Weeks

Set a hard number for how much you'll allow any single day, and any single week, to cost you. Hit the daily number, you're done trading for the day — full stop, not "just one more to get it back." Hit the weekly number, you're done for the week.

For a ₹5,00,000 account, something like ₹15,000-20,000 as a daily limit (3-4% of capital) and ₹30,000-40,000 as a weekly limit (6-8%) is a reasonable starting range.

The weekly number matters more than people give it credit for, because bad days compound. Down ₹20,000 on Monday, down another ₹20,000 on Tuesday, and you're already 8% into the week with three trading days left. The instinct at that point is almost always to trade bigger on Wednesday to claw it back — and that instinct is exactly how a bad week becomes the week that ends someone's account.

Rule 4 — Resist the Urge to Average Down

Averaging down means adding to a losing position at a worse price to bring your average cost down. It's a debatable strategy in long-term stock investing. In short-dated options, it's close to indefensible.

The reason is structural, not emotional: options have an expiry date built in. A ₹100 call you bought keeps decaying toward zero the closer it gets to expiry — see Theta Decay & Time Value for why — no matter how many additional lots you throw at it. Every lot you add just compounds the loss if your original view was wrong, and even a correct-but-late directional call can still lose if the move doesn't arrive before Theta finishes eating the premium.

Rule 5 — Don't Bet the Whole Book on One Style of Trade

A portfolio built entirely from buying options struggles through quiet, high-IV stretches where nothing moves enough to justify what you paid. A portfolio built entirely from selling options can lose months of steady income in one large, unhedged move — a Budget day, an RBI surprise, a global shock.

A mix along these lines is worth considering rather than committing everything to one approach:

• Roughly 40-50% in directional option buying (calls and puts)
• Roughly 30-40% in defined-risk selling structures — Iron Condors and spreads, where the worst case is known upfront
• Roughly 10-20% in event-driven plays like straddles ahead of major announcements
