Analyzing The Expert Advisor Performance

Hi All

For example I use 5 different indicators in an expert advisor to generate buy sell signals with usual tp,sl etc.. extras.
Instead of analyzing the whole equity of the expert advisor, is it possible to analyze how much each indicator contributed profit in the expert advisor,, ?

Or is it possible to measure any drawdown of each indicator between opening and closing a trade in the expert advisor ?

Has anyone have any opininon?

ls it possible to build a voting mechanism in an expert advisor to see how much profit each indicator contributed?
