Longer time frames such as monthly, quarterly and yearly suggest same speculation of the Pound going higher on Yen.
Fundamental news in the UK has been in support of slow growth out of global recession with no great news of the Yen pulling up in any steady and consistent way.
For less experienced traders, please note that it is always important to look at your longer time frames as well it is equally important that your charting and supports what is going on in the world of FUNDAMENTALS which should never be excluded. In my experience of trading, I believe firmly that is the prime tool of investigating and proving the fundamental data "which is always correct and exact" "not speculated"!!!
