I prefer trading mostly major currency pairs like EUR/USD and GBP/USD. I have not traded minor or exotic currency pairs till now.
It is different in terms of liquidity and ability to move in trends which in part depend on how much it correlates with economic cycles of seasonal trends. The less factors affect some currency the more trend-like behavior of it we can expect.The pair makes no difference, other than the time frame and trade size you need. For example, I can trade USD/MXN just as easily as USD/CAD. However, I based trades off of weekly charts.
this is very common pair but really effective to trade comfortably.I usually prefer to trade with EUR/USD.
