Duplicate of Post in Software (not sure correct forum) I need an (old) install of  Interactive Brokers' TWSRTDAPI  (for Excel 2016 on Win7 ). ...yes... I realize this is cave man technology, please humor me Some version between 9.4 and 9.9 Older copies used to be available on IB's sites, but no longer exist. If there are any software packrats out there with a copy to share, I would appreciate the help. Statistics: Posted by ilscot — 53 minutes ago
