I have the following if its of any use:
Date ..............Open...... High....... Low........ Close.... Volume.......... Adj Close
4-Nov-05 .....5,431.......5,446......5,418......5,423......964,006,656...5,423.
My data goes back to 1984.
If you mean data in regards to daily, as in, where was the FTSE at 1030am on 4th November 1999, I don't think you'll find it. But good luck anyway.
Yours
