Wing, I did spend a lot of time drawing that up.
None of us have enough data to draw conculsions, so, as I mentioned a few weeks back, everything on this board is speculation.
I was trying to explain that Spooz's custom pricing ($200) and auto-spreader ($600) modules have price tags that under-cut their TT counterparts. Are you aware that these modules are attempts to directly compete with TT? Have you seen the types of software used by futures traders?
I write trading software for a living, and I do indeed have a very good understanding of how Spooz uses Excel. To make any statements about speed, they have clearly created a DLL plug-in for Excel, using C++ or C#.
