Unadjusted DIA and SPY minute data back to 2003

[phantomdereal]

I backtested my strategy on DIA and SPY by using IQFeed minute data. Their data quality is fairly good but can only go back to May 2007. Now I would like to do a more extended backtest to cover the much more quiet time between 2004 and 2007.

I did some research on the net and till now only found kibot offering unadjusted data back to 1998. But after checking their sample data, I have to say the quality is not very good. So is there any other data provider offering unadjusted and high quality (both price and volume) minute data back to 2003?

Phantom, in case you cannot find the Unadjusted DIA, perhaps the DJIA index data itself may do the trick. (Not 100% accurate though).

And by the way, if you have access to the intraday data for the Dow Jones Ind in text file (csv, etc..) could you share it with me?

Good luck.
