David,
For reliable and long histories of fundamental data (including
analysts' estimates) you really have to use professional data-
providers, and unfortunately (but understandably) that costs money. I
use Datastream (who own IBES/First Call) and Bloomberg. Both
Bloomberg and Reuters do not have as much historic data as Datastream.
Re Q2, I integrate macro, fundamental and technical data in quant
models, and yes, due to the ThCSV-plugin (now to be replaced by the
SQL-plugin)Amibroker allows one to combine this data, backtest it,
etc.
This is my approach. In general, as others have pointed out also,
find / create a niche, the precondition for success.
Just my opinion. Hope it helps.
