Every week, I mark key levels for each currency pair to see how price reacts to them.
As you see on the charts, I have marked the last Week's and Last Month’s Highs and Lows for the 6 major pairs (actually they are 7 but there was no room for NZADUSD, but you can do that one by yourself as a practice)
Why are these levels important to us? Because they are kind of support and resistance levels and when price approaches to them, any breakout or rejection on these levels is very important: (Lows act like support and Highs act like resistance).
So, take a note for yourself and apply them on your chart to have an efficient setup for key levels. Mn : Monthly (Red Lines) , W: Weekly (Yellow Lines)
