Hi, Market XLS is a great product but I am running into problems with downloading data into one of my quantitative stratigies. I am trying to download ~9 months of daily adjusted close data for ~200 separate companies into Excel in a single sheet. I tried to do this using the Close_Historical function in the spreadsheet cells with the date in the left column, tickers in the top row. Unfortunately this takes several hours to complete (the spreadsheet downloads the data for the close of each day and each company separately). I can probably put up with that because this is for a strategy that I run monthly. My real problem is that once the spreadsheet ha completed the download it appears to start re-loading the data again, even though I have set formula calculation option to manual rather than automatic. Does anyone know of an alternative way to do what I want or a way of preventing continuous data downloading?
