[Ffts-develop] Recent FFTS development

[Mark H. <mgh...@ya...>]

A few points:

1) I've been spending the last couple of months basically
   gutting the underlying evaluation graph stuff and rebuilding
   it to make it more stable. There are a lot of changes in the
   code that aren't even in cvs on soureforge... though they
   should be within a couple of weeks.

2) Odd lots shouldn't be a problem. Right now, the option object
   is actually *more* suited to this than to an exchange-traded
   option - it really corresponds to an option on a single
   stock, so you can do as many units as you like. And the
   expiration date is saved just as a date, not as a pointer to
   a listed option expiration month or something. I suspect that
   I'll keep this flexible option object around (which you
   could easily use for your warrants), and build a new "listed
   option" object to make it easier to do normal exchange-based
   options trading.

   Building new classes to represent different types of security
   isn't completely straightforward, but it's not too hard
   either, especially if the new security types can use market
   data in common with other types (so you don't need to build
   classes for the market data as well). I've tried to design
the
   ffts so that it's relatively easy to extend and customize
this
   way.

3) I've sort of stopped gathering daily market data for stocks
   and options (I had to cut off my lovely always-on internet
   connection a while ago :( ), but I did notice that the
program
   I use to snap and save option prices wasn't working right.
   Not sure what's up with that; the work on the fundamental
   architecture hasn't given me much time to play with the
higher
   level stuff.

Anyway, watch this space for more info on the next version of
the ffts, which should be appearing within the month.
