But, to say the true, not all the pairs are fully correlated with this BrainTrading M30 system.
For example, it may be difficult or almost impossible to trade some crosses:

The system is "trading" the pair/trend which system understand. Not as trader understand. If it is the signal (according to the indicators' system understanding) so it is the signal. Irrespective off the trader's opinion.
It is the different between signal system (BrainTrading M30 for example) and price action system (channel trading system or maksigen system for example).
Signal systems are thinking for you and instead of you. Trying to think.
The price action systems can not think for you as you will not see any command
"to open the order right now!".
So, if you are using any signal system (BrainTrading M30 for example) you may want to go to the history on the chart to understand:
will I trade this pair this week or not.
Jut open GBPUSD for last week or GBPJPY for last week with this system and you will understand about what I mean. Sometimes you are openning the chart with BrainTrading M30 and you can say to this BrainTrading M30: "I do not want to trade this pair this week and please don't ask me about it".
Why system? Why this word "system"?
I say "system" and everybody say "wow, this guy is having the System" ...

Do not make too much attention to that as the word "system" is related to the
indicators' system
or
system made by indicators
It is related to the indicators on one chart and it is not related to something we can call as a System (wow!).
I know that some people are calling "system" instead of simple say "EA". Because if they say "EA" so many people will ask: "elaborate please". But if they say "a System" so no one will ask because it is a System (wow!).
In my case it is just a indicators' system, or indicators' set, or set of many indicators on one chart.
