In Episode #1 of our Options Crash Course, we trace everything back to the source - the option contract. Inside of an option contract between the long side and the short side, the strike price, expiration date, underlying stock, and quantity are all fixed, whereas the price of the contract itself is floating.
Then we take a look at the transaction itself, which isor counterparty. The market maker stands ready to buy at the bid price or sell at the ask price, and serve as the other side to any order we might want to execute.
Lastly, we move through thelong call, short call, long put, and short put, with the gimmes and gotchas presented for each.
