Anybody have extensive knowledge of the forex market - particularly GBP

Good afternoon chaps,

I'm really interested in the forex markets, in particular the market for my home currency, the GBP. I'm looking to pursue a forex broking role but I haven't extensive knowledge of the sector - i've always been more of an equities guy.

I was hoping that somebody working within the forex market could enlighten me and share some market knowledge on a macro scale:

I was wondering what the major trends and forecasts are and what signifiant movements have occurred in the past couple of years - and why this has happened?

Also, what essential knowledge should I gain before applying?

All the best,
TBG
