Are there any free, open source VBA addins or R packages that can be linked using the yahoo finance/Google finance/other data sources api to continuously download intraday data into excel or R?

This is the closest I have found to loading D/M/Y prices into excel but it doesn't allow for intraday. I have a few charts with my own technical indicators that I would love to have have refreshed every few seconds with new data. I know that yahoo finance only provides delayed data but that's not an issue for me.

I miss having Bloomberg :(

you need real-time tick in order to achive this. IB, esignal, iqfeed both provides RTD/DDE api to excel integration.

Hi Clebson, thank you for sharing this. Any free data providers that can allow you to load intraday data into excel? I don't mind if its delayed and I am not concerned if its not tick. –  jessica Jul 1 '13 at 22:47
    
@jessica Yahoo offers 15 minutes delayed stock updates. They have a CSV you can download and parse it quite easily. so in your excel sheet just set a timer using an excel API ( Application.OnTime ) as for example (: –  Clebson Derivan Jul 1 '13 at 23:26
