Comparing pairs

Hi,
Even though I trade live and have done well both naked and with indicators, I consider myself an absolute newbie in other pairs than EUR/USD.

I found a very interesting a post I found here in FF which makes me wonder if there are hidden opportunities (hidden for me by ignorance on the subject) on pair comparison.
The post said:

"As long as GBP is falling simultaneously against USD and JPY it will continue to fall against all others. This is true for all other majors. This is a tiny secret that is so easy that most traders even do not consider it valuable."

You can see it here. The post is by Parisienne.
I found it extremely interesting. As I said, I'm sure it's because I've been focused only in EUR/USD all this time.
Does someone here trade looking for pair comparisons which could translate into a profitable system?

To me, at least, it is a tool I often use to evaluate if it is Weakness in one half of the Pair or Strength in the Other.

EUR/USD is Falling.
Is it caused by EUR weakness or USD Strength?
A quick peek @ Other USD Pairs & EUR Pairs suggests {not definatively} it is USD Strength.

Where the USD is getting the Strength is another question. One for which I no answer.

i must confess that it happens to me also...i'm just focusing on the EUR/USD since i got to the FX world, the difference between us is that you are already trading live, and i'm still over trials. But i would thing that it would be not that reliable to try out a strategy built for the EUR/USD over another pair. They have to react different.

thanks quantum for the hint

intresting post

I don't know about you, but I really think that people behave differently when there's money involved.
You can throw a stone to a target and hit every time. If they tell you that you're betting your house maybe you'll miss.

I think that you MUST trade with money once you have the basics in Forex. You can use a mini or micro account, but real money.
Why? Because market is moved by greed and fear, and you can't really experience those emotions with monopoly money.
Blew your $100,000 in your demo account? It doesn't matter, here's another $100,000. Want more? Check for demos of $2 million.
BUT: Blew your $100 account? There's a meal for the family, there's a toy for the kids, there's a nice something for your wife, there's a toy for you.
Now that's real and you've LOST that toy for the kids, you blew it and nobody is going to give it back.
I think it's healthy to trade with money. It doesn't have to be a lot, but you must feel the greed and the fear. If you don't, you'll just postpone something that will come eventually, something more important than green and red bars.
