We can use this to post tools, sheets, and code projects we build to help investors or ideas for fun. Anyone is free to post their own projects, excel, and code here. I am a bit rusty as I have been sick for a lot of the year but I whipped up some quick calculators for the Graham formula and Nathan's fair EV value modification yesterday. I built a binomial options pricing calculator for American options, Kelly criterion for trading, DCF, and probably more tools scattered in various files. I need to find them(got a new computer this year) update the source codes, and package them as an executable for Windows and an app for Mac users.
Viruses, malware, scams, and other malicious software and intent will be a permanent ban.
Files I share will include the source code, the exe/app, readme, and software license which will be an MIT license which means open source, modifiable, and very few restrictions comes without a warranty, and released from liability. Most of my current projects are CLI although I may build a GUI at some point or combine projects.
