I have seen a tip from somewhere that in order for you to be become successful always in your trading, you have to to a sniper rather than a machine gunner.. If you trade always see all opportunity, every indicator, every momentum, etc. before starting to trade. Don't be hasty to trade every signal day. You just have to find that one trade that can bring you good profits and not painful losses.
It depends on your style, there are many traders that are only looking to get some small profits with each trade they are not expecting that their trades skyrocket or anything, while there are others that do only a few trades but they need that each trade brings very important profits, which one is the best? The one that feels more natural to you, I am a long term holder so if I became a trader I will prefer the sniper approach that you are talking about.
