We’ve all seen them those guys with lots of screens. There is good reason for having multiple charts visible at once.
Let me explain why.
Let’s say we concentrate on GBPUSD, EURUSD, USDJPY, just three charts, imagine a large move on USD, USD moves up, all 3 charts will reflect the move, showing a strong bullish USD. This can be a good confirmation or even signal for trading. Being aware that other charts may be affected by fundamentals on that chart.
It is well worth viewing multiple charts at once if you can. Just to gauge what is going on.
