[R-SIG-Finance] TAQ data and Eric Zivot's HF Library

[Eric Zivot]

This library has gotten a bit old, and there are a bunch of new techniques
for the analysis of high frequency data (especially for realized variance
etc) that have appeared recently. I am in the process of substantially
updating the library with the help of one of my Phd students and this may
involve a port to R. I'll keep the list informed.

I find myself needing to analyze TAQ high frequency data.

Eric Zivot and Bingcheng Yan wrote a paper and released code here:

http://faculty.washington.edu/ezivot/research/hfanalysis.pdf
http://faculty.washington.edu/ezivot/research/HFLibrary.SSC

That can handle TAQ data, and has some other useful characteristics for high
frequency data cleanup.

1. Has anyone thought about porting these scripts to R ?

2. Some functions rely on diff.timeSeries from S+Finmetrics.  I'm not aware
of a correllary function in R.  Does anyone have any ideas on replicating
diff.Timeseries?

If I can get permission, any ported code would be made public so that no one
else would have to repeat the work.

Regards,

  - Brian
