About Finwin Options (OptionChain)

Finwin Options (OptionChain) will return a WDDX structure with the following keys for base_symbol, high, prev, last, close, open, low and desc. It also includes keys called call_recs and put_recs that is a wddx recordset with a single row for each month it calls.

Symbol - symbol of option with a root (i.e. DLQ) and a 2-letter Month/strike identifier (i.e. UW). Therefore, DLQ UW is the symbol for DELL Computer, September, 17.5 strike price
Expire - This is a whole number representing the date of expiration. First 2 positions are the month, next 2 are the day, and the next 2 are the year. 092201 would be 9/22/2001.
Strike - The strike price of this option.
Last - Option price at last trade.
Change - Change from previous price.
Bid - Current Bid.
Bid_size - Current Bid_size.
Ask - Current Ask.
Ask_size - Current Ask_size.
Volume - Days volume.
Inc_Volume - Last Trade size.
OpenInt - Open Interest.

By passing a form parameter called puts and setting it to "true" you can also have "Put_recs" included in this return packet.

The optional parameter Fields is a list of all fields you wish to be returned. Utlizing this option will give you complete control over the data returned. If you leave this field blank or omit it altogether, you will be returned all applicable fields for the particular security type your are requesting.

You also have the ability to rename the field names. Among other benefits, this feature will allow you to more easily migrate existing applications to FinWin. To utilize this feature, simply use the format: Fields="NEWNAME=OLDNAME,...". For example, to rename SYMBOL to SYM, use: Fields="SYM=SYMBOL".
