just test it , and link it wth your way of trading ,
so many years in the market i find that the most important thing in forex is to believe in the way you are trading , if you dont believe it , it hard to win from this , so once its hard for you to believe that using moon phases to win in this market , so simply dont use it . all im saying you can give it a try ..... for me i always link it with the way i trade
the last movement of the market look how was in the screen with moon phases
