I have TS2000i and wouldnât consider it obsolete and use it all the time. True they no longer support it but I donât need support, but TS has a user support forum for it. Most TS8 strategies and indicators will run on 2000i (in some cases key words will have to be changed (e.g., âSell Shortâ to âSellâ)). And they just introduced some enhancements to their graphics package (e.g., maximum number of lines that can be plotted) so things will start to diverge there.
I run TS2000i under XP and use eSignal as the data feed (eSignal supports their ActiveX plug-in for TS2000i). Iâve have had no stability, blue screen, or freeze-up problems of any type.
The biggest difference is that TS8 supports automated trading (with the TradeStation Securities broker only) and that it will not let you import third party data. One of the common complaints about TS8 is that they only have a few months of tick data available, but with 2000i you can import as much third party data as you want (but you have to pay for it).
If you want to trade intraday, the eSignal Basic data feed will cost about $80/month for use by TS2000i vs. $100/month for TS8 that includes the data feed. So for that cost differential, TS8 may be a good choice. However, if you only need end-of-day data TS2000i can import data from a number of venders in MetaStock or text format for $20-30/month for free data from Yahoo.
