how much precentage accurate signal
and how much price after 2 week free trial
No one can give you accurate signal. All these guys either they are a member to other paid channels or you got some skills to guess how markets can move but they want to play safe by selling those signals to others so that they will be always in a profit side.
Anyway, OP is offering a free trial option so you can just try and find out how accurate their signals in two weeks. But remember always try with a small amount on these signals.
