Do your own research.
also I think market is ranging 80% of the time. does it means you will win 80% of the time with a ranging EA?
Who said that ? On what base ? What is the definition of a ranging market ?
what ? it's well known that market ranges most of the time. We can measure it with ADX.
a ranging market is a market where oscillators are profitable, a trending market is a market where price goes strongly in one direction and MA is the indicator of choice.
MAs don't work in a ranging market because they are too late, and oscillators don't work in a ranging market because the reversing signal is then wrong
this is trading 101, and most traders agree to that.
You are contradicting yourself.
