Object Oriented Programming (OOP) Developer needed to modify an existing expert/indicator mql4

It is an indicator that uses data mining and uses that data to produce results. I want to modify it to produce the first signal like it normally does and then subsequent signals should be produced without using the zigzag position and use the first signal position to make the calculations. Also alter the indicator to use only two prediction modules when there's no fractals until there's one and produce results normally. Add an option for nrp arrow signals, adding a zigzag with alll their repainted points and adapting the code to make it nrp, this should be normal predictions but nrp from the original version of the indicator
