Quote from geoMEAN:
Tradestation is great as a testing platform if you are a programatic trader, but their unrelentless inepititude as a company and the unreliability of their platform has finally caused me to start looking elsewhere.
As of 5/1/09 they are retiring their ONLY WORKING STABLE RELEASE of their platform, version 8.3.
8.4, 8.5, and 8.6 all have their problems that make it impossible to programatically trade in real time with code.
They have not responded officially to the multiple pleas from advanced customers not to retire 8.3.
The really annoying thing is that they only gave us a week's notice that 8.3 would be retired.
I'm really starting to look elsewhere. I partially left them as a broker and just used them for data a long time ago, but now I am looking for a full solution-- brokerage and data that fits my needs.
