Mastering 0-DTE & Zero-to-Hero Execution

Some plain words. A strike is the fixed price in the option. A call option gains when the index rises above its strike. “Out of the money” means the strike is above the index today, so the option has no value if used now, only the chance that it will. A premium is the price you pay for that chance. It is like a token advance on a flat: if the deal does not go through, the advance is gone.

Illustration. NIFTY is at 24,500. You buy a 24,700 call, far above the index, for ₹10 per unit. One lot of 65 costs 10 × 65 = ₹650. That is the most you can lose. For the option to give back even your ₹650, NIFTY must close above 24,700 + 10 = 24,710 at expiry, a rise of 210 points on the day.

What if it works? Suppose NIFTY closes at 24,800. The call is worth 24,800 − 24,700 = 100 points. That is ₹100 per unit, ten times the ₹10 paid. In rupees, 100 × 65 = ₹6,500 received against ₹650 paid, a gain of ₹5,850. That is the picture that makes these trades attractive.

What if it does not? If NIFTY closes at or below 24,700, the option expires worthless and the ₹650 is lost in full. That is a loss of 100% of what you put in. Now add up a series. Ten such trades that all fail cost 10 × 650 = ₹6,500. A single win of ₹5,850 would not even repay that. The arithmetic asks a plain question: how often must the win come to cover the losses, and can anyone know that in advance? No one can.

Implied volatility (IV) is the amount of movement already priced into an option. Before a known event, such as a policy announcement or results, IV is often higher, in the same way that umbrellas cost more just before the monsoon. So the market has already charged you for the possible surprise. You gain only if the actual move is larger than the movement priced in.

After the event, IV usually falls sharply, an effect often called an IV crush. A far out-of-the-money option can lose value quickly, even when the index moved in your favour, if the move was smaller than the option needed. This is one reason such trades lose so often around events.

The takeaway: a catalyst raises both the chance of a large move and the price of the option. It does not tilt the arithmetic in your favour by itself. Anyone who says an event “makes it a good setup” is describing a hope, not a calculation.

Recovery is harder than the loss. If you lose half your capital, you need a 100% gain, not 50%, to get back. This is why sizing matters more than picking the exact trade. A run of losses in cheap options is common, so the size of each trade decides whether you can stay in the game.

SEBI has published studies on individual traders in equity F&O, and they have repeatedly found that most of them lose money after costs. The FY26 study was reported to have found that about 88% lost money, but this must be checked against the SEBI publication itself. Needs verification. Whatever the exact figure, the pattern across the studies is consistent, and it is a fair reason for caution.

What this does not tell you: it does not prove that every trader loses, or that you will. It shows that the odds are hard, that costs matter and that the stories of huge gains are not the typical result. If you still choose to trade, decide your limits first and treat every rupee as capital you can afford to lose.
