How strong are the major currencies compared to each other since last month?
A quick look is to put each RSI on top of each other to get a first impression.
On top (purple line, value 82) we see the the USD/JPY steady climbing while at the bottom (light purple line, value 25) is the NZD/USD remaining weak.
The light blue line is the AUD/USD at 41 while the USD/CAD in black at 72.
Brown at 58 is the USD/CHF and EUR/USD, red at 39 close the GBP/USD at 37 in green.
This is an easy way to get a first impression how they move in strength/weakness over the last month.
On the RSI above the 50 level means more upward pressure than downward pressure while the opposite for RSI levels below 50.
Before trading, you need a closer look of course on each currency pair.
