Your Strategy Isn’t Killing Your Account. Your Position Size Is.

Nobody blows up an account because they picked the wrong strike once. They blow it up because their position size was too big for their account. Most F&O content talks about entries, levels, and market views, but the real question is simpler: if this trade goes wrong, how much can I lose and still come back tomorrow without panic-trading? If your account is ₹1,00,000 and your max acceptable loss is ₹2,000, that number should control the trade. Buy at ₹80 with a stop at ₹50, and your risk is ₹30 per unit. ₹2,000 divided by ₹30 gives you 66 units. If the lot size is bigger than that, the trade is too big for your account. “Only one lot” is not risk management if one lot already breaks your risk limit.

The scary part is how fast the math turns against you. Risk 10% per trade and seven bad trades can cut your account in half. Risk 20% and it can happen in four. And losing streaks are not rare; even decent traders hit them. Recovery is worse: down 50%, you need a 100% gain just to break even. Down 90%, you need 900%. That’s why “I’ll trade bigger to recover faster” is usually the sentence right before the account gets cooked.

For small accounts trading Indian index options, the textbook 1-2% risk rule is often hard because the minimum lot itself may be too large. So either use a real stop, trade smaller instruments, trade less often, or admit your actual risk is higher than you think. Open your last 20 trades and check your losses as a percentage of your account. Most people who think they risk 2% are actually risking 4%, 6%, 8% or more. Your edge doesn’t matter if your size doesn’t let you survive long enough to use it.
