Options are derivatives, which mean their value is derived from the value of an underlying investment. Most frequently the underlying investment on which an option is based is the equity shares in a publicly listed company. Options are traded on securities marketplaces among institutional investors, individual investors, and professional traders and trades can be for one contract or for many. Fractional contracts are not traded.
Participants in the options market buy and sell call and put options. Those who buy options are called holders. Sellers of options are called writers. Option holders are said to have long positions, and writers are said to have short positions. 
Types of option
In the special language of options, contracts fall into two categories - Calls and Puts. A Call represents the right of the holder to buy stock. A Put represents the right of the holder to sell stock.

Call Options

A Call option is a contract that gives the buyer the right to buy 100 shares of an underlying equity at the strike price for a period of time. The seller of a Call option is obligated to sell the underlying equity if the Call buyer exercises his option to buy on or before the option expiration date.
