your question is so open-ended / general. anyway ... This is the best of the best : price goes up. enter after the end of the retracement. price goes up. then it makes a U-turn. Take this reversal signal. and vice versa.
totally agree. trading is more of an art rather than science. hard to describe artistic things with words.
I find it a strange go between of the two. There is a scientific logic to it to an extent but the nuances of a strategy are very particular and personal like that or the style of an artist as you say. Precisely why the shortcuts most new traders look for don't work. There is no secret sauce that works for everyone.
