Is there a source of historical US stock end-of-day data that contains the official open/close prices from listing exchange (that is, the prices that usually come from the opening/closing auctions)?
The providers I've look at so far (norgate, csidata) use the first and last regular-hours trades from the consolidate tape as their open/close prices.
Edit: I should mention that I'm also looking for a source that has 20-30 years of history and includes delisted stocks.
