"Excellent analysis, the supports and resistances are a great guide for defining market entries. The most complicated thing is that these are not exact lines, but work zones, and the most complicated thing is to define the area of ​​this zone. How do you define the breadth of your support and resistance zones?

Using the USD/JPY daily chart from the setup in this post as an example, you can see I just placed a line on the spike marked with the green arrow. It was the first and most obvious rejection, so I used that. Then I drew the grey box to encompass as much of the obvious wicks on other touches, turning it into a zone:

Honestly though, there's no right or wrong. This is all just personal preference for me.
