Nice to have some real facts. Thanks.

How is your term "item" defined? Is an item the data for one chart,
one data series, or what?

Sounds good.

Good. (Like TradeStation has always done.)

Should definitely change. I have loaded 1000 days of SPX 1-tick bars
into TS2000i (1.35 million bars) and it works great!

Much better, but ASCII is pretty verbose for such data.

This would be OK if lots of historical data is available. Is there a
policy on how much historical data will be available? It seems as if
the major benefit of backtesting would be lost if there is too little
data for meaningful backtesting.
How about back-adjusted futures data. How far back will back-adjusted
data go. What kind of back-adjusting will they do?
Speaking of facts, is there a source on the TRAD website where the
accurate technical specifications of TSPro are listed. That would
save us a lot of guessing and testing.
Thanks.
