I have a book on technical stock analysis that I am converting to R code. The rules of these trading systems are not particularly difficult (comparing today's price, to five days ago, then...), but they are complex. I have reduced this complexity down to an Excel spreadsheet and I can assist you with understanding them, but I need your help with the for-loops and conditional logic. I can also afford additional pay for this project as it progresses.
I look forward to working together and thank you for your consideration.
