How much history does Interactive Brokers make available?

[ZenEng]

I searched their site and ET but found no information how much historical data is kept.

Anyone have a pointer to a resource that tells how much tick, minute, and day history is kept and available for download?

points to this table that states there is almost no historical data for IB:

I believe it is only 30 days.

This link sort of suggests one year: http://www.interactivebrokers.com/php/apiUsersGuide/apiguide/api/historical_data_limitations.htm

But it is kind of an obscure place to define that!

This also seems relevant: http://www.interactivebrokers.com/p...orical_data.htm#XREF_67601_Viewing_Historical
