I'm looking for a programmer with expertise in gold

Hello, I already have the skeleton of a working EA, but I need to add a few more filters. I need someone to help me who has experience with gold and knows which indicators don't work and can suggest indicators that might work.

Furthermore, I need you to plot lines at these prices and only enter those lines, as well as only operate buys from a daily percentage and sells from a daily percentage, among other filters.
