A short call
is a bearish to neutral options trading strategy that capitalizes on downward price movements in the underlying asset and the passage of time (theta decay). A long call
is a bullish options trading strategy that strictly capitalizes on upward price movements in the underlying asset.
A buying to open
a long call gives a trader the right, but not the obligation, to purchase shares of a stock at a predetermined price on a predetermined date
On the other hand, selling to open
a short call obligates a trader to sell
shares of a stock at a predetermined price on a predetermined date, assuming the short call is in the money
For every trader that buys a call option, there was theoretically another who sold that same call option
