I am a data analyst working for an also trading firm, I specialised in python, data scrapping/visualisation and linux system administration. I know CAD as I use it for some personal projects, so I relate to what you are trying to do. The timeline I am putting in is 7 days but I can shorten it if you need it done asap.
I would like to collaborate in the future and will work on free(until you can sell your software) but right now I am in a tight spot with my finance and need to make some quick money, I would like to be paid for this one.
Hope we can come to some mutual understanding and if not then, good luck with your venture, I wish you the very best.
