Especially when using a custom view, you may find that the number of columns chosen exceeds the available space to show all the data. In this case, the table must be horizontally scrolled (left to right) to view all of the information. To do this, you can either scroll to the bottom of the table and use the table's scrollbar, or you can scroll the table using your browser's built-in scroll:
When you buy an option, the risk is limited to the premium that you pay. Selling an option is the equivalent of acting as the insurance company. When you sell an option, all you can earn is the premium that you initially receive. The potential for losses is unlimited. The best hedge for an option is another option on the same asset as options act similarly over time.
The price at which you agree to buy the underlying security via the option is called the "strike price," and the fee you pay for buying that option contract is called the "premium." When determining the strike price, you are betting that the asset (typically a stock) will go up or down in price. The price you are paying for that bet is the premium, which is a percentage of the value of that asset.
