How have you dealt with adjusting saved historical data, specifically using the IB API?
As far as I can tell, currently, I need to perform the calculations described on Quandl's blog.
I haven't looked closely enough into IB's fundamental data offerings to know if I'll need to get some of those data values from a different source (e.g., Quandl).
What has your experience been with this? Am I approaching this in the right way?
