From my observation of some older traders who are consistently profitable in the market, I have observed that they usually are very consistent with their strategy or approach to the market.
Just as starting to trade on one pair first is important for a beginner trader, it is also necessary for a new trader to know that the easiest way to become confused is to try to learn different trading strategies from different traders or sources at once.
One trading strategy is enough to make you successful until it is no longer working.
If you are going to use one strategy then you probably your strategy won't be good for all purposes. That's why for some strategies only work in certain cases and they probably master those cases to make a benefit on their strategy. You'd probably need to at least master one strategy before even bother to try other strategies, sometimes you don't need to learn all of the strategies just to get profit.
