    There is a non-zero probability of doing that - use the Bloomberg API in Excel if you have ISINs in Excel and if the whole work is to be done for Excel analysis. Otherwise, if it is for some expert system, use the Bloomberg API with C++/C#.

With the O-U model you have a reverting process that does not take a look at current values of s(t) while the...
