Hi johnnyalpha,
Don't take this wrong. You and Limitup have just caught my interest/curiosity on this.

Seems most if not all brokerage houses with online trading support the Windows OS of at least the more recent flavors. Also the Mac/Apple OS.

Is this just a science project for you ??

What OS's are advertised to be supported from the brokerage houses you are looking at ??

I just don't understand. It seems like you are doing a lot of work and sounds like you are taking on a lot of risk using "home brew" OS software that has not been fully tested and approved for use by your brokerage house ????

Just some thougts,
Thanks, Lee
