Since there is NO ETN Forum, please pardon my post in this EFT Forum. If you have, or have reference to spreadsheet validating sequence thru Roll with intermediate variable results, please respond or PM me! No BS or drama please! Am looking to validate a 2 or 3 day sequence passing thru the CBOE VIX Futures Settlement Date. Reference pages 25&25 of "http://www.ipathetn.com/US/16/en/documentation.app?instrumentId=259118&documentId=6204338" Alternate source of info: "https://acfr.aut.ac.nz/__data/assets/pdf_file/0007/29887/485340-Modeling-VXX.pdf" page 6. While the posted formulas seem quite simple and clear, I have been unsuccessful in obtaining "reliable results", so seeking insight from someone who has.
