 | | Option chains can also be imported from a simple comma delimited text file if you have access to data from providers not explicitly handled by the software. |
 | | As well as providing a simple way of selecting options, the option chain facility also lets you compare, for a given option, spread or combination, the impact on profit and loss of increasing or deceasing strikes for a given expiry date, moving to different expiry dates for a given set of strikes, or both. |
 | | On-line option chains are also used to produce a number of "sentiment indicators": put/call ratios (open interest and current volume), and "open interest configuration" charts, showing the open interest for puts and calls by strike. |
