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 :(
