Risk first. Then everything else.
Short, plain-English lessons on sizing, costs, options and checking who you take advice from. No tips, no hype — the things we wish every trader knew before their first F&O order.
Risk first
The 1% rule: size every trade from its stop-loss
How much to buy is a risk question, not a conviction question. The arithmetic that keeps one bad trade small.
Where a stop-loss goes, and why it is decided first
A stop-loss is the price that proves the idea wrong — not a number you can afford to lose.
Reward-to-risk and win rate: the two numbers that decide everything
Why a 40% win rate can make money and a 70% win rate can lose it.
Costs
F&O basics
Options in plain words: calls, puts, premium and expiry
What an option buyer pays for, what a seller takes on, and what happens on expiry day.
Why bought options lose value while you wait (theta)
Time value melts every day, fastest near expiry. What that means for option buyers.
Lot sizes, margin and leverage: why F&O cuts both ways
A lot is a large position bought with a small margin. SEBI's own study of who wins and who loses.
Research & safety
How to read a research call
Entry, target, stop-loss, horizon, rationale, risks, disclosures — what each part tells you.
Spotting stock-tip scams and unregistered advisers
Guaranteed returns, Telegram 'VIP' groups, profit-sharing offers: the signs, and how to check a SEBI registration.
