Thanks for the reply. I think I have found the problem which is with me as I suspected. I need to creat a new symbol in the Indices file I believe. I have never needed to do this before. The Indices folder only contains the FTSE 30 index together with 5 FTSE 350 sector indices. The FTSE 100 is not included but I have added it and the data now loads. I wonder why this index was not included in the standard symbols. Seems an important one to me.
