Pinescript expert - enabling function partially coded

Dear expert pinescript programmer Required is a pinescript specialist and expert to work on a strategy that was fully functioning prior to 3 additional filters added to the code. I have full specifications for this strategy. I have the working code prior to the changes and the code with an attempt to the additional functionality to it. Required is the make a additions that are coded long to actually work in the existing program - logic issue. Then make the short do the same processes as the long. The above only fixes additional filters and functionality to an existing strategy that is already fully functional. The script with about 2000 lines of code is only given after you enter into the contract. I have the working code prior to the changes and the code with an attempt to the additional functionality to it. You will need to supply examples of complicated strategies you have worked on successfully in the past. This is a urgent technical issue to resolve.
