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.
I agree with what you say that this is an OP, because the more strategies you use, the more complicated the situation becomes for you. At least if it's just one or even, let's say,
a maximum of two, it's still good as long as you don't exceed two strategies.
This is all I can say that it is fine, as long as you are comfortable using the strategy that you want to use in the actual trading that you will do in any
exchange that you will do trading activity.
