Frequently asked questions
The basics, answered.
What is options trading?
Options trading is buying or selling contracts that give the right — not the obligation — to buy or sell an underlying like Nifty at a set strike price before expiry. Traders use options to speculate on direction, hedge existing positions, or earn from time decay.
Where should a beginner start?
Start with the option chain — the single screen that shows every strike's price, open interest and implied volatility. From there, learn Max Pain and the Put-Call Ratio for sentiment, then move on to simple strategies. Practise in the simulator before risking real capital.
Is options trading risky?
Yes. Options can expire worthless, and short (written) positions can carry large or even unlimited risk. Always understand the payoff of a strategy before you trade it, and never risk money you can't afford to lose.
