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.
All strategy works depending on how you use it or apply them, reason being that a strategy I'm using to gain profit might be given to another trader and it won't work for him, not that the strategy is not working, but the trader might not follow the rules that backs the strategy to become profitable, like risk, management, being patient, emotional control and finally waiting for the terms of entry to be met.
