But waiting for the right set-up gives you an edge in the market, when you trade only when you sees an opportunity, you will mostly comes out profitable, as long as you knows the craft a little, but probing the market every now and then will only make you lose money, because trading is more of patience and knowledge.
Others just copy, others are too lazy to study, so they only guess,
and others think that trading is just gambling, even though it really isn't.
A very good and experience trader do not take anything less than 1-3 risk reward ratio, because it's just like you are risking 20 dollar on a single trade to make 60 dollar if it goes your way, so if you can win like 40% of the trade you took, then you will surely be a profitable traders, but if you are taking 1-1 or 1-2 risk reward ratio, you would need to win like 70% of your trade before you can be profitable, which is very difficult to achieve.
