Hi Tomasz, I've seen this statement several places in regards to IB
> Historical data requests can go back one full calendar year. and in my backfilling for 180 days of 1-minute bars through AB, I some times get data that is older than 180 days. Which is nice as it makes testing more valid. Has anyone tried to get a full year of 1-minute bars from IB? If it hasn't been tried, seems like it's worth a shot...
