I have developed a small excel query that allows me to pull quotes from those 3 sites and prepare the data to be added to the manual entry .txt files.
Yahoo finance is ok, but I could not find some mutual funds and pension plans there, so I manage to get the quotes from those 3 sites. I strongly recommend ariva because is lightning fast. I also use the other 2 but for very special occasions because they are slow to give the quote back.
I hereby upload the V1 of the excel file with instructions, the query and 3 examples. Please give it a try and let me know your toughts and recommendations. I have some holidays now and could further develop it although I am not an IT guy ;-)
Hope it helps you as much as it helps me every saturday when reviewing the portfolio evolution.
All the best,
