Futures and Options — F&O — let traders take leveraged positions on indices and stocks. That leverage is exactly why they're powerful and why they're risky. This primer keeps the jargon to a minimum.
Futures, briefly
A future is an agreement to buy or sell an underlying (like the Nifty 50) at a set price on a future date. You don't pay the full value upfront — you post margin, which is why futures are leveraged.
Options: calls and puts
An option gives you the right, but not the obligation, to buy or sell at a set price:
- Call (CE) — the right to buy. Traders buy calls when they expect a rise.
- Put (PE) — the right to sell. Traders buy puts when they expect a fall.
Key terms:
- Strike price — the level the option is tied to.
- Premium — what you pay for the option.
- Expiry — the date the option settles (weekly or monthly in India).
- Theta — time decay; options lose value as expiry approaches.
Why risk-first sizing matters more here
Because leverage amplifies both gains and losses, a single careless trade can do real damage:
- Size every position around a defined stop.
- Risk a small, fixed percentage of your account per trade.
- Respect expiry days — they're whippy and unforgiving.
- Never average down on a losing leveraged position.
Leverage doesn't make you right faster — it makes you wrong more expensively.
