SO simple modification (make indicator faster 4 lines of code)

I am seeking a coder who has experience in converting an MT4 indicator & EA(.mq4 file, source code provided) to TradingView's Pine Script. The indicator should be identical to the original, with the same inputs and settings. Upon completion of the task, the coder will send me the Pine Script indicator & EA along with the full source code, and the project will remain confidential. This task should be straightforward
