The following comment from you confused me:
“Also, in my opinion focusing on a single asset like this is not the way to go at all. Could be really good for a period if it’s doing well but the reverse is also true.”
The reason it confuses me is because Petko has a whole trading course just using EURUSD. And, also somewhere in the courses I have taken from Petko I believe I learned it was best to use different EURUSD strategies to reduce risk. So if it is not advisable to just use EURUSD then why the course on just trading EURUSD. Further what other currencies would I then need to use to make a correct trading portfolio and how many difference currencies is the correct amount? So this is now all confusing to me.
