Allan, can you point me to a copy of the spec for the UMDS?
It does sound like one of the better starting points.
I've heard something to the effect that current versions of
UMDS have certain weaknesses in handling historical data,
but that Kent is working to fix those weaknesses. I'd be
able to comment more intelligently about that if I could read
a real spec.
I understand UMDS has three fatal weaknesses as far as I'm concerned:
1: It doesn't allow the importation of custom data into its
realtime database. Same weakness as Omega's server. I've
found a workaround for this problem in TS 3.5, but that
workaround isn't practical for TS 4.0. Who knows about TS 5.0?
2: It doesn't work on any computer that's connected in any way
to any network. This means I couldn't use it on my computer
that's networked with my wife's computer, even though our
activities are totally unrelated, except we share resources
like printers, backup devices, etc.
3: It doesn't run on Linux. How can any software be considered
"open" if it requires the use of a Microsoft product?
Aside from the proprietary nature of the MS environment, I
consider my trading workstation to be "mission critical" and
no MS operating system meets that criterion.
