If you dont have experience writing software , or software requirements...dont bother with upwork, unless you're willing to use the people who charge $100-$200 and hr and are truly professionals.
Your ability to communicate what you want in a precise fashion is extremely critical to your success. Even more so if you hire an amateur. I've written several end-to-end trading platforms, and have outsourced some of the work thats not worth my time (on upwork)...very much a mixed bag. I spent almost as much time guiding the dev as I would have needed just to do the job myself.
I would love to talk with you and send you a video of my system. Can we set up a phone call anytime this week?? Please send me a private message and we can set something up.
I already have a system programmed on Tradestation but TS has too many limitations. I am ready to take on this task.
I can't commercializ it the way I need to.
