The TradeStation was designed from the ground up not to work with time series alone - it was designed to be one of the best strategy creation and automation packages in the world....I am saying that, in terms of ease and breadth of strategy creation capabilities, EXCEL is far superior to TradeStation...which was a very pleasant discovery for me....pleasant because the ratio of books and freely available information on excel programming is 1 to 1000 as compared to the information about TS programming.,,,even if I have access to TradeStation forum,,,
