Ok,I understand "put" is the right to sell and "call" the right to buy but now i don't understand this :
A put option (sometimes simply called a "put") is a financial contract between two parties, the seller (writer) and the buyer of the option.
The put allows the buyer the right but not the obligation to sell a commodity or financial instrument (the underlying instrument) to the writer (seller) of the option at a certain time for a certain price (the strike price). The writer (seller) has the obligation to purchase the underlying asset at that strike price, if the buyer exercises the option.
Why is the buyer selling and the seller purchasing,i mean what are the buyer and a seller in this case?
Or maybe buyer is called so cuz he s buying the option(put) which then lets him sell?
So if you want to buy money through options then you should sell a "put" option first,is that how it goes?
