I trade pretty much every pair, except the crappy ones.
But I do my analysis on the weekend to see what currencies are the strongest and what ones are the weakest, then take it from there.
I trade in the present, and what is happening now.
Unlike what you will read here, I have the simplest strategy you could think of, go in big and go in hard - although I don’t stick around for 300+ pips per trade.
I don’t, and have never done any of this “risk 1% of your account” stuff, and been trading a very long time.
A trader just practice on one pair not does good he should try other pairs. He can not grip on all trading pairs however few pairs are best to have practice on them. If he wants success he should monitor time to time 3 or 5 pairs. Certainly he will got a chance to do good trading in anyone of them.
I always favor to trade major currency pairs as forex is a challenging field. And what I think is: I can better craft my trading strategies and planning with relatively stable currency pairs.
I am fairly new to Forex so I stick with EUR/USD. It seems to more slow and is pretty easy to see stuff coming. I also watch GBP/USD and USD/JPY. Sometimes I jump into GBP/USD but that is fairly fast moving.
If you love doing scalping, it’s more appropriate to choose the lowest pair, otherwise good result will not come in spite of having knowledge and experience.
