Online stock options trading is a form of stock trading in which trades have been agreed upon in advance. Many of the new online stock traders might get overwhelmed by the fact that what stock options trading really is? Like in usually online stock trading, stock options trading also involves two parties, i.e. a buyer and a seller.

The buyer and the seller agree through an agreement that the buyer will buy or the seller will sell a particular amount of stocks of a particular company before or up to a pre decided date. After the time expires, the option expires as well. Option is called upon by anyone of the both parties.

There are two types of stock trading options prevailing in the market. They are as follows:

1. A call option

A call option is that in which a potential buyer of the stocks purchases a right to buy certain number of stocks of a company before a particular time period at a particular price. The buyer who has bought the call option has already paid the fee for buying that right; he may or may not want to purchase the stocks before that particular time period depending on the profitability or loss he can decide either way. The seller with whom the call option buyer has made the agreement will have to provide that particular number of stocks of a particular company to the buyer of the option no matter he has gains or losses.

2. A put option

A put option is totally opposite of the call option. In a put option a seller buys the right to sell the stocks of a particular company at a particular price before a particular amount of time. In this case the other party that is the buyer in the agreement will have to buy the stocks at that particular price if the seller chooses to exercise his right to sell at a predetermined price.

Options stock trading can be very difficult to handle for a newbie. People who don’t really know what this trading works should first learn the different terminologies, ins and outs of the options stock trading before taking any risk. In case of options trading sometimes the loss can be overwhelmingly higher than a loss through usual online stock trading.
