Murrey Math Strategy - Profitable or not?

Can experts tell me that Murrey Math Strategy is profitable or not..?
Is it professional source of forex ?

Mr Murrey who invented the system was very successful.
I am currently testing some of the indicators but I don't know which one is correctly coded.
a lot of them I have been testing have been showing different values.
I'm hoping someone here on FF can share a confirmed one.

it is good with USD pairs ..
there are 2 ways of using MML ... use as pivot point means if price goes above 4/8 or go below 4/8 then buy or sell ..2nd (reversal) if price touch upper last level +2/8 then sell
and if touch -2/8 lower last level then buy

thank you bro
BTW i use price action but want to imporve my trading so that's why i asked about Murrey mathline...
I want to use murrey mathlines with price action strategy....so what you think can it best strategy if i use combiantion of both of them ?

I used MM a lot in the past great for confirmation. It can work for some and not others, you need to develop your own, that is the only way you will ever be profitable. It is your business

It is / was a trader in FF, who has the MM as trading system, but or I didn't had enough patience to learn it or just didn't work
As I remember he has a real name "Markus", not sure the nickname / username.
