Call Option
A contract that gives you the right to buy the underlying at a set price — your bullish bet, with loss capped at the premium.
Definition
A call option (CE on NSE) gives the buyer the right, but not the obligation, to buy the underlying — an index like NIFTY or a stock — at a fixed strike price on or before expiry. The buyer pays a premium for this right; the seller (writer) receives it and takes on the obligation to deliver if assigned.
Why it matters
A call is the simplest way to take a bullish view with defined risk. The most a buyer can lose is the premium, while the upside rises with the underlying. Calls also offer leverage — a small premium controls a full lot — which is why call volume and open interest on the chain reveal where traders expect upside.
Example
NIFTY spot is 22,500 and you buy a 22,600 call for a premium of 120. If NIFTY rises to 22,900 by expiry, the call is worth 300 (its intrinsic value) — a profit of 180 per unit. If NIFTY stays below 22,600, the call expires worthless and you lose only the 120 premium.
