Important update on 16. February 2019: Some links, and especially downloads links on this personal website may not be uptodate, as I recently transferred the whole site from www.finaquant.com to software.tuncalik.com.
Give me some time; I will check and correct them one by one.
I decided to offer all the software introduced on this website open-source and free.
Check my shared folder for most uptodate downloads. Open-Source downloads of the C#/.NET libraries Finaquant Calcs and Finaquant Protos are also included in this shared download folder as zipped Visual Studio 2012 files.
You may contact me if you need any help or consulting for my analytical software.
