Forex is too volatile to be 100% predicted. There are always chances of losing even when both technical and fundamental analysis are done properly.
In demo, you can try anything you want. Like trading a CL contract 3 years out from the front month. You may get a fill. But that does not translate to REAL-WORLD PERFORMANCE.
True! Real trading is completely a new spectrum. There are so many aspects that come into the picture, and it can be so overwhelming..
The wider spreads of exotic currency pairs can lead to increase in the total trading cost and profits can become negligible.
for that reason it is more appropriate to avoid all exotic pairs , but in demo account you can use this kind of pair to see the performance how it works.
Exotics pairs contain currencies from countries that are developing or have unstable economics. It is better to avoid them as you need to have strong fundamental and technical knowledge. Plus,it is very expensive to trade them because of hefty spreads.
