Option is actually contracts between buyers and sellers, usually covering #100 shares of underlying( stock or ETFs ). They work a lot like insurance: one side pays a premium for protection or opportunity, while the other side collects that premium in exchange for taking on an obligation.Options chain
Each option has it:
• strike price
• expiration date
• price
• strike price
• expiration date
• price
Strike - is agreed price 'level' on the CONTRACT. Where seller is happy to buy 100 shares for which he is rewarded with a premium. While the buyer pays that premium for protection if the stock moves to this level.
Expiration date → The last day the option contract is valid, after which it disappears.
Price (premium) → The upfront cost paid by the buyer to hold the option, collected by the seller.
