अक्सर पूछे जाने वाले प्रश्न
What does "in the money" mean?
Call: stock > strike. Put: stock < strike. ITM = has intrinsic value. OTM = no intrinsic value, only time value. Exercise decision depends on whether ITM at expiry.
Is my loss capped at the premium?
On long options (buyer), yes. Loss max = premium paid. On short options (seller), loss is unlimited (calls) or large (puts). Never short options without stop losses or understanding max risk.
How does time decay affect profit?
Longer-dated options worth more. As expiration approaches, time value erodes. Buyer loses if stock doesn't move; seller benefits. For 45+ days to expiry, time decay is slow; under 7 days, rapid.
