The Art of Trading the professional way is to find important Sup/Res zone or lines and see how the market reacts to them. The more and more popular Market or Volume Profile can help to find them and to understand why the market reacts there and with some experience to set SL and TP. Price often runs from VAL to VAH or res versa or breaks out and runs back to VAH/VAL. POC are often points where the market stopps.
