I am interested in purchasing a copy of TradeStation 20001. I believe that this is the version which allows you to import external data, which is useful to me since I'd like to do intraday testing for the NQ contracts going back several years. Unfortunately, the current copy of TS only allows you to use the data that they have available in their system, which is limited to the last ~18 months or so. If you have a legal copy of TS2000i (with manuals, etc.) and are interested in selling it for a reasonable price, send me a PM. Thanks, EricP
