Calls, puts, and premium
A call (CE) gives the right to buy; a put (PE) gives the right to sell. Buyers risk mainly the premium paid. Sellers collect premium but take larger risk if the move goes against them.
On NSE, stock and index options expire on fixed cycles. Liquidity, lot size, and open interest matter as much as the directional view.
Practice before live F&O
Use the Options Strategy Builder to sketch payoffs from end-of-day bhavcopy premiums, then watch educational AI Options bots that open iron condors and credit/debit spreads when filters pass.
Paper practice will not match live SPAN margin or intraday fills — treat it as mechanics training.
