Is there any charting software that can graph the yield curve (schatz, bobl, bund, buxl / 2y, 5y, 10y, 30y) over time in a 3d graph? would be interesting to have in realtime..
In AmiBroker you can do such graphs, see 4th post here http://amibrokerforum.proboards.com...sing-tiny-bit-imagination?page=1&scrollTo=333 Other alternatives R, Matlab, Python, ...
If you look at the IBKR forward curves, it has historical and the current curves. Very easily done in Excel RTD , if your data provider has historical data. Finding the inexpensive provider with historicals is the hard part. Use interpolation for months that have not been listed.
Btw: Barchart has a free, limited use API and was cognizant of a need for a European Grouping. You can also demo barchart trader.
