What do you mean "until"? Tradestation is advertising on their website and in print that there is 20 years of intraday futures data available. Is this not the case? For the e-mini's, do they have the full 3:45pm to 3:15pm the next day? Is it tick data? 1 minute? or what? Say I want to stick with my current broker but want to use TS7 for system testing. Given the alternative between $199 a month for subscribing only or $99 per month for brokerage customers, isn't the wise choice to park $5k in a TS account to get the $99 rate?
