The first part of learning is being able to find a line or level where you expect something to happen which is tradable. Something which is clear and provides a well defined risk.
However, the question is, "How much should you expect price to move away from the level"? Would you expect a pullback? Would you expect a reversal? etc.
You start building more on top and you can then become a bit more choosy about which ones to trade, which ones to leave alone. That is not a problem, because all a sudden more opportunties start appearing under your nose you never noticed before, so you can be more selective.
Sorry, I have not answered the question, but it's a little beyond what I have seen Will go over in the thread, so I am not sure how much more I should say at this time.
