New trading systems platform

[Joel Reymont]

What is wrong with using lists for this purpose?

You do process your time series sequentially, front to back, and I  
think you can do it recursively as well. Erlang has tail recursion  
and you can easily drop the first element of the list with [H|T].

I create http://groups-beta.google.com/group/uptick to disucss points  
specific to the platform as opposed to Erlang.

     Thanks, Joel
