Best Stocks Historical Data Provider?

If you want to include fundamental data, Portfolio123 is a great option. It uses the compustat database, and includes delisted stocks.

That's a great site but I need workable data for backtests (meaning data on csv files or similar) rather than just charts. Thank you!

Thank you, but what about the split/merge adjustments and suvirvorship bias free requirements? Are they managed by Tradestation?

Corporate events like splits are not in the raw data that can be exported. You could plot some of the corporate events onto the charts with TradeStation. As far as survivorship bias they do not have charts of stocks that are no longer listed on the exchanges.

Thank you!
 
I can totally recommend PremiumData (dot net) for EOD stock data, fully adjusted / maintained. I only wish they did intra-day as well : )
 
Can anyone recommend a cheap source for historic MINUTE data for US Equities - back-adjusted and including de-listed stocks? I'm not sure if TradeStation includes de-listed? Also, not sure they adjust for dividends?
