trend following trading system in excell

Hello, I am looking for a freelancer to develop a trend following trading system in excel for me. My risk tolerance for this system is high, and I am looking for a system focusing on stocks. I prefer this system to act in a short/medium-term time frame. The system should also have an appropriate money management system in place. The details of the system will be provided to the selected freelancer. Thank you for considering my project.
