The best advice for beginners to stay away from mechanical systems and work on something that works and has logic and such efforts will give you plenty to swallow and something that just works and that is price action without any help. Without help means no goodness whatsoever, work in and out day by day and figure out why prices are moving in that direction and what are the possible reasons (not fundamental), then after a year or two your practice has something that works and you only need to chart and one or two failures does not matter when you see one trade and it gives you more than you expect. in my personal view if you are a beginner in forex trading then you have to choose your indicator for forex trading, i would suggest to all beginners to choose the moving average indicator which really is a profitable and great indicator to gain profit in forex
