What Is an Option?
An option is a contract: you pay a small premium for the right (not obligation) to buy or sell a stock at a fixed price later. If the trade doesn't make sense at expiry, you simply walk away.
- Call: right to BUY — you want the price to go up
- Put: right to SELL — like insurance, it pays out when the stock drops
→ The panel on the right is a call buyer's P&L at expiry. Drag the spot price slider — the dollar number, the green dot on the curve, and the verdict text all update live.
